HAND

Traumatic peripheral nerve injuries cause chronic pain, disability, and long-term reductions in quality of life. However, their incidence after extremity trauma remains poorly understood.

The IBM® MarketScan® Commercial Database from 2010 to 2015 was used to identify patients aged 18 to 64 who presented to emergency departments for upper and/or lower extremity traumas. Cumulative incidences were calculated for nerve injuries diagnosed within 2 years of trauma. Cox regression models were developed to evaluate the associations between upper extremity nerve injury and chronic pain, disability, and use of physical therapy or occupational therapy.

The final cohort consisted of 1 230 362 patients with employer-sponsored health plans. Nerve injuries were diagnosed in 2.6% of upper extremity trauma patients and 1.2% of lower extremity trauma patients. Only 9% and 38% of nerve injuries were diagnosed by the time of emergency department and hospital discharge, respectively. Patients with nerve injuries were more likely to be diagnosed with chronic pain (hazard ratio [HR]: 5.9, 95% confidence interval [CI], 4.3-8.2), use physical therapy services (HR: 10.7, 95% CI, 8.8-13.1), and use occupational therapy services (HR: 19.2, 95% CI, 15.4-24.0) more than 90 days after injury.

The incidence of nerve injury in this national cohort was higher than previously reported. A minority of injuries were diagnosed by emergency department or hospital discharge. These findings may improve practitioner awareness and inform public health interventions for injury prevention.

The purpose of this study was to determine the impact of upper extremity peripheral nerve blocks on emergency department (ED) utilization after hand and upper extremity surgery.

We reviewed all outpatient upper extremity surgeries performed in a single Midwestern state between January 2009 and June 2019 using the Indiana Network for Patient Care. These encounters were used to develop a database of patient demographics, comorbidities, concurrent procedures, and postoperative ED visit utilization data. We performed univariate, bivariate, and multivariate logistic regression analyses.

Among 108 451 outpatient surgical patients, 9079 (8.4%) received blocks. Within 1 week of surgery, a greater proportion of patients who received peripheral nerve blocks (1.4%) presented to the ED than patients who did not (0.9%) (P < .001). The greatest risk was in the first 2 postoperative days (relative risk, 1.78; P < .001). Pain was the principal reason for ED utilization in the block cohort (53.6%) compared with those who did not undergo a block (35.1%) (P < .001). When controlling for comorbidities and demographics, only peripheral nerve blocks (adjusted odds ratio [OR], 1.71; P = 0.007) and preprocedural opioid use (adjusted OR, 1.43; P = .020) conferred an independently increased risk of ED utilization within the first 2 postoperative days.

Peripheral nerve blocks used for upper extremity surgery are associated with a higher risk of unplanned ED utilization, most likely related to rebound pain. Through proper patient education and pain management, we can minimize this unnecessary resource utilization.

Approximately 56% of patients diagnosed with carpal tunnel syndrome present with bilateral symptoms; however, few studies have investigated bilateral simultaneous endoscopic carpal tunnel release (ECTR) and postoperative effect on return to activity. The purpose of this study was to evaluate the length of recovery in patients who received bilateral simultaneous ECTR, including pain medication requirements, return to activities of daily living, return to work, and return to recreational activities.

A retrospective analysis was performed on patients who underwent bilateral ECTR by a single hand fellowship–trained surgeon from 2013 to 2019. Demographic, operative, and clinical outcomes were collected via chart review and a telephone interview. Student t tests and χ² tests were conducted for analysis.

Eighty patients were included in the study; 40 were successfully contacted for telephone interview follow-up. Patients reported an average of 2 days of use of postoperative narcotic pain medication and an average of 5, 7, and 19 days of return to activities of daily living, work, and recreational activities, respectively. Female patients reported more days of narcotic pain medications (1 day vs 3 days, P = .0483) and an average of longer return to work than men (9 days vs 5 days, P = .0477). Manual laborers reported longer return to work (9 days vs 5 days, P = .0500). Older patients (aged >65 years) reported longer return to recreational activities (39 days vs 11 days, P = .0189).

Simultaneous bilateral ECTR is a successful procedure with shorter recovery times than reported previously. Female patients, manual laborers, and older patients experience a longer recovery and should be counseled appropriately.

Delayed-onset carpal tunnel syndrome (DCTS) can develop weeks and months after distal radius fracture (DRFx). A better understanding of the risk factors of DCTS can guide surgeon’s decision making regarding the management of DRFx and also provides another discussion point to be had with elderly patients when discussing outcomes of nonoperative management.

We reviewed 216 nonoperatively managed DRFx between June 2015 and January 2019 at a single level 1 trauma center and senior author’s office. We identified 26 patients who developed DCTS at a minimum of 6 weeks after DRFx, which constituted our case group. The remaining 190 patients served as the control group (non–carpal tunnel syndrome [CTS]). Differences between case and control group were evaluated through univariate and multivariate analyses.

The prevalence of DCTS among nonoperatively managed DRFx was 12%. In univariate analysis, volar tilt (VT) and teardrop angle (TDA) were significant independent predictors of development of DCTS. Multivariate logistic regression analysis determined that the odds of developing CTS increased by 12% and 24% for each degree of decrease in VT and TDA, respectively. No other significant risk factors were identified.

Decreasing VT and TDA are the most significant risk factors associated with DCTS in nonoperatively managed DRFx. These are simple and reliable radiographic measurements that provide significant prognostic value. These parameters can be used to guide surgeon decision making regarding management of DRFx in the elderly while aiding patient expectations and outcomes following nonoperative management of DRFx.

The purpose of this systematic review was to determine the metrics used to assess outcomes after treatment for carpal tunnel syndrome.

We performed a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines of level I and II randomized controlled trials of treatment for carpal tunnel syndrome. We searched the PubMed/MEDLINE electronic database for studies on treatment of carpal tunnel syndrome from January 2008 to January 2018. A total of 105 studies were included in the final analysis. The metrics used to assess outcomes in each studies were collected, compared, and described.

Nearly all the studies used a patient-reported outcome measure (PROM) to assess outcomes (94%). The most common PROMs used were the Boston Carpal Tunnel Questionnaire (60%) and the Visual Analog Scale for pain (51%). Electrophysiological testing and physical examination were also commonly used to assess outcomes (50% and 46%, respectively). Cost, sleep, and return to activities of daily living were assessed in a minority of studies (1%, 1%, and 5%, respectively).

Successful treatment of carpal tunnel syndrome is commonly defined based on a PROM, highlighting recent efforts to measure outcomes from the patient’s perspective. Other patient-centered metrics such as return to work and sleep quality, however, were rarely reported, whereas objective measures such as nerve conduction studies were prevalent. Further work is needed to determine patients’ preferred method of measuring outcomes after treatment for carpal tunnel syndrome to inform goal-directed decision-making and treatment.

Small joint reconstruction of the hand poses a significant challenge, especially in children where both functional motion and preservation of the epiphysis are desired. Auto-transplantation of whole joints is the only way to reconstruct a functional joint that maintains growth potential. Historically, nonvascularized toe-to-finger joint transfer has been criticized for high rates of avascular necrosis and joint dissolution, while vascularized transfers seemingly resulted in increased durability of the joint space and epiphysis. However, certain populations remain poor candidates for microvascular reconstruction, such as those with congenital deformities or sequelae from trauma or infection. In our case series, we demonstrate that a simplified nonvascularized surgical technique and careful patient selection can produce stable, functional joints.

Nonvascularized toe-to-finger joint transfer was performed in 3 children between the ages of 4 and 6. Reconstructed joints included 2 proximal interphalangeal (PIP) joints and 1 metacarpophalangeal (MCP) joint. Donor grafts consisted of second toe PIP joints harvested en bloc to include the epiphysis of the middle phalanx, collateral ligaments, volar plate, and a diamond-shaped island of extensor tendon with its central slip attachment.

Follow-up ranged from 7 to 29 months. Each patient demonstrated functional improvements in joint motion and stability. Postoperative radiographs confirmed adequate joint alignment and persistence of the joint spaces. Epiphyseal closure was observed in 1 patient as early as 25 months postoperatively.

Nonvascularized joint transfer should remain a practical consideration for small joint reconstruction of the hand in certain pediatric patients.

Poland syndrome (PS) is a congenital condition characterized by pectoralis hypoplasia and an ipsilateral hand anomaly that frequently necessitates surgery in childhood. This study aimed to determine long-term functional and psychosocial implications of PS.

Patients underwent strength testing of their affected limb by comparing with their contralateral arm. They completed Disabilities of the Arm, Shoulder, and Hand (DASH), 36-item Short-Form Health Survey (SF-36), and several Patient-Reported Outcome Measurement Information System (PROMIS) surveys. Aggregate scores were compared with population norms.

Twenty-eight patients were enrolled, and 16 returned for strength testing. The average age was 42 years (range, 18-65 years), and the average follow-up was 25 years (range, 1-52 years). Dynamometer testing showed decreased strength in shoulder internal rotation and abduction/adduction, hand grip, and key pinch/tip pinch. Average DASH and SF-36 scores were comparable with population norms. The PROMIS Upper Extremity score (46.2) was significantly lower than the average 50 (SD, 10.0); the Social Roles score (57.3) indicated significantly less disability than the general population. Seventy-nine percent reported higher than average satisfaction with life, 82% had normal self-esteem, and 21% and 4% met screening criteria for depression and anxiety, respectively. The Derriford Appearance Scale revealed that 68% of patients identified PS as their most self-conscious feature, with 36% reporting subsequent life adjustments.

This cohort of PS patients self-reported more favorable functional, psychological, and emotional outcomes than expected based on significant shoulder and hand strength deficits. Despite these deficits, patients make adaptations, allowing fulfilling lives with psychosocial functioning similar to their peers.

Extensor tendon adhesions occurring after proximal phalangeal (P1) fractures are not uncommon. A previous report described the use of an adipofascial flap (AFF) to prevent adhesions after dorsal plating of the P1. The purpose of the study is to examine the results of open reduction and internal fixation with the use of an AFF (F group) and without (N group, that is, no flap used) in a larger group of patients.

A retrospective study involving a period of 11 years was conducted involving results of 21 unstable fractures of the P1 of the fingers in 18 patients. In all, 12 fingers were treated without any flap (N group) and 9 fingers were treated with the AFF (F group). For each patient, the total active motion (TAM) ratio, and the grip strength (Jamar) ratio were assessed, and adverse effects and the 10-point visual analogue scale (VAS) score were recorded. For statistical analysis, sample characteristics were described using mean ± standard deviation and median, and a Bayesian approach was used for inferential analysis.

In the F group, the TAM ratio (84% ± 13% vs 65% ± 17%) was higher with a lower rate of adverse effects (OR: 0.067, 95% CI, 0.0035-0.58,) and a lower VAS score with evidence of the positive effect of the AFF. The Jamar ratio was similar in the 2 groups (F group 80% ± 25% vs N group 79% ± 19%) with no associated effect of the AFF on grip strength.

The AFF is a reliable tool to reduce adhesions between plates and the extensor apparatus of the P1 and may be useful to improve finger function after plating of P1 fractures.

Therapeutic, Retrospective, Level IV

Orthopedic surgical patients in general have been found to be at higher risk for developing opioid dependence in the postoperative period. However, there is conflicting evidence in the literature whether opioid exposure after hand surgery leads to prolonged use. In the absence of a nonoperative control group, it is not clear whether prolonged opioid use in hand surgical patients is related to undergoing a surgical intervention. The purpose of our study to compare opioid prescription fulfillment patterns in surgical and nonoperative patients in a hand surgery practice.

We retrospectively compared 320 patients that underwent elbow, wrist, and hand surgery procedures with 741 nonoperative patients treated by 2 hand surgeons. The Pennsylvania Drug Monitoring Program (PDMP), a mandatory statewide database, was used to evaluate the primary outcomes of filling more than one opioid prescription and filling opioid prescriptions beyond 6 months of the index surgery or clinic visit. Bivariate and multivariable logistic regression analysis was performed using the following variables: surgery, prior benzodiazepine use, and prior opioid use.

There was no difference in prior opioid use (15.2% vs 16.9%, P = .51) or prior benzodiazepine (10.4% vs 8.4%, P = .33) use between the nonoperative and operative groups. Patients that underwent surgery had a higher incidence of filling more than one opioid prescription (20.9% vs 8.8%, P < .001). However, continued opioid use was not statistically different between nonoperative and operative patients (2.8% vs 5%, P = .08). Bivariate analysis demonstrated that prior opioids (odds ratio [OR] = 12.94, P < .001) and prior benzodiazepines (OR = 1.95, P < .001) were significant independent risk factors for prolonged opioid use. Multivariable analysis demonstrated prior opioid use to be the only independent risk factor for prolonged opioid use (OR = 12.58, P < .001).

Undergoing outpatient hand surgery do not appear to be an independent risk factor for filling opioid prescriptions beyond 6 months. Significant risk factors for prolonged opioid use include prior use of controlled substances, particularly prior opioid use.

The seesaw test consists of flexion and extension of the thumb metacarpal on the trapezium, with continuous axial pressure to keep the metacarpal base reduced in the carpometacarpal (CMC) joint. We aim to evaluate this maneuver compared with the grind test.

We prospectively enrolled 80 participants from March 2017 to March 2018 at a single institution, excluding those who had previous thumb surgery or pathology. Each participant underwent both seesaw and grind tests by 2 independent examiners. We included 24 patients with a mean age of 73 years in the CMC osteoarthritis group (Eaton stages 2-4) and 44 patients with a mean age of 66 years in the control group (Eaton stages 0 and 1). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and multirater κ measure.

The seesaw test had a higher sensitivity than the grind test (42%-71% vs 13%-17%), but a lower specificity (82%-86% vs 91%-98%). The PPV was more consistent between examiners for the seesaw test (63%-68% vs 42%-80%), and the NPV was higher (73%-84% vs 66%-68%). There was a slight agreement between the attending surgeon and the fellow performing the grind test (κ = 0.08) and a moderate agreement between the attending surgeon and the fellow performing the seesaw test (κ = 0.59).

The seesaw test is superior to the grind test, with a much higher sensitivity, slightly lower specificity, more consistent PPV, and slightly higher NPV. Therefore, the seesaw test could be a valuable addition or even replacement for the grind test, and we recommend considering it in daily practice.

To perform a comprehensive osteologic investigation into trapezium anatomy and investigate the relationship between anatomical factors and osteophyte formation, focusing on sex-specific differences.

This was a cadaveric study involving 1233 trapezia and first metacarpals. Two subgroups (“Control” and “Main Study”) were established. The “Control” cohort was used to identify features of the trapezium in specimens devoid of osteophytic change. The prevalence and severity of osteophytic change were investigated in the “Main Study” cohort. Sex differences were specifically assessed. Regression analyses were used to identify factors associated with osteophyte formation.

Three discrete surface morphologies exist at the trapezium trapeziometacarpal (TM) facet: heart, quadrilateral, and bean. Controlling for height, men have a larger trapezium TM facet surface area. However, the trapezium assumes the same off-center saddle shape in both sexes. The presence of osteophytes at the basilar joint is a common finding; no differences in osteologic prevalence exist between sexes. The progression of osteophytic change complements the radiographic Eaton-Littler classification system. The trapezium TM facet increases the surface area with incremental osteophyte involvement, with the degree of surface area expansion correlated with increases in the severity of osteophytic change. Increased age, increased surface area, bean morphology, and decreased volar joint depth are associated with more severe osteophyte formation.

Anatomical features of the trapezium may contribute to osteophyte development. Although the prevalence of osteophytic disease appears equal between sexes, sex differences exist in some anatomical parameters. These differences may help explain the increased prevalence of symptomatic basilar joint disease in women.

Knowledge is lacking on patient goals and motivation for carpometacarpal joint osteoarthritis (CMCJ OA) surgery. The objective of this study was to explore patient goals and motivation for surgery, whether patient goals were reflected in self-reports of pain and function, and factors characterizing patients highly motivated for surgery.

This cross-sectional study included 180 patients referred from their general practitioner for CMCJ surgical consultation. Goals for surgery were collected with an open-ended question, categorized with the International Classification of Functioning, Disability and Health coding system, and compared to self-reports of pain and function. Motivation for surgery was rated with a Numeric Rating Scale (NRS, 0-10, 0 = not motivated). Factors characterizing patients highly motivated for surgery (NRS ≥ 8) were explored with multivariate regression analyses.

The mean age of the participants was 63 years (SD = 7.6), and 142 (79%) were women. The most common goals for surgery were to reduce pain and improve arm and hand use, but these were not reflected in self-reports of pain and function. Fifty-six (31%) of the patients were characterized as highly motivated for surgery. High motivation for surgery was strongly associated with reporting more activity limitations (odds ratio [OR] = 4.00, P = .008), living alone (OR = 3.18, P = .007), and a young age (OR = 0.94, P = .002).

Decisions on CMCJ OA surgery should be based on assessment and discussion of patients’ life situation, hand pain, activity limitations for, and goals and motivation for surgery. According to the european league against rheumatism (EULAR) recommendations, previously received conservative and pharmacological treatment should also be evaluated.

The elbow is one of the most commonly dislocated joints, and dislocation is usually accompanied with an assortment of soft tissue injuries. The purpose of this study was to retrospectively analyze and describe the patterns of ligamentous, tendinous, and muscular injuries in patients with an acute elbow dislocation and subsequent magnetic resonance image (MRI) evaluation.

From 2008 to 2020, 235 patients clinically diagnosed with an elbow dislocation were seen in the department, of which only 19 underwent an MRI of the affected elbow. Twelve patients met inclusion criteria, and MRIs were evaluated by both a radiologist and an upper extremity orthopedic surgeon. Magnetic resonance images were assessed for injury to the ulnar collateral ligament (UCL); radial collateral ligament (RCL); lateral ulnar collateral ligament (LUCL); common flexor and extensor tendons; biceps, brachialis, and triceps tendons; fracture; and joint effusion.

Magnetic resonance imaging findings included the following: UCL was injured in 11 of 12 patients; RCL was injured in 9 of 12 patients; LUCL was injured in 9 of 12 patients; common flexor tendon was injured in 11 of 12 patients; and common extensor tendon was injured in 9 of 12 elbows. The biceps, brachialis, and triceps tendons showed injury in 1 of 12, 2 of 12, and 2 of 12 elbows, respectively. Four elbows had at least 1 fracture present, whereas 8 demonstrated an effusion.

In this series, injuries to the UCL and common flexor tendon were most common. Although ligamentous injuries are exceedingly common in elbow dislocations, large studies of MRI findings prove difficult due to MRI costs.

Despite increased utilization of conservative measures for displaced olecranon fractures in elderly patients, in whom operative fixation may be complicated by coexisting comorbidities and declining bone quality, the noninferiority of nonoperative management has yet to be proven. The purpose of this study was to review nonoperative management of displaced olecranon fractures in the elderly patient population.

A literature search of the PubMed database was performed using the term olecranon fracture. Papers included those with results for patients aged 65 years and older published between 1990 and 2018 in the English language. Data were pooled to analyze outcomes and complications of nonoperative management of olecranon fractures in the elderly patient population.

Four eligible studies combined for a total of 69 patients with 70 fractures with an average age of 83.8 years (71-95 years), female predominance of 88%, and a mean follow-up of 12.4 months who underwent nonoperative management of displaced olecranon fractures. While only 25% of fractures went on to radiographic union, the mean Disabilities of the Arm, Shoulder, and Hand score was 16.9 (0-59.6), the mean arc of motion was 138°, and 92% of patients achieved excellent results. One-quarter (26%) of the patients experienced complications: radial head subluxation (1), skin sore (1), degenerative arthropathy (1), pain on movement (2), click in movement of the elbow (5), and local pain (8).

Displaced olecranon fractures in patients aged older than 70 years may be effectively managed with nonoperative measures to produce high satisfaction and functional range of motion.

Surgeons are sometimes presented with patients with distal radius fractures who present in a delayed fashion or lose reduction after several weeks of attempted closed management. There are limited studies on delayed surgical treatment of distal radius fractures to assist providers in decision-making.

We conducted a matched cohort study to compare radiographic outcomes and complications for patients with a distal radius fracture treated with delayed (3-5 weeks) or early (0-2 weeks) surgical fixation. Patients ages 18+ who underwent open reduction and internal fixation of distal radius fractures by a volar approach at 2 Level I trauma centers between 2003 and 2015 were eligible. We measured radiographic outcomes and reviewed medical records to determine operative approach and complications.

There were 25 cases and 50 controls matched for age (18-87), sex, and AO fracture type. The delayed group had surgery at a mean of 24.8 days from injury and the early group at 5.6 days. There was no statistically significant difference between the delayed and early cohorts in radiographic parameters on injury x-rays, in improvement in radiographic parameters on first postoperative x-rays, or in maintenance of radiographic parameters at union.

We did not find significant differences in radiographic outcomes or complication rates between patients with delayed versus early surgical treatment for distal radius fracture. Providers treating patients with late presentation or late displacement have the option of surgical fixation beyond the first few weeks after injury.

III (Retrospective matched cohort study)

After a distal radius fracture (DRF), severe pain, disabilities, and pain-related psychological problems can arise and sometimes remain ~1 year later. DRF-related disabilities have been assessed with questionnaires but not by kinematic evaluations; the kinematic features of DRF patients are unknown. Here, we investigated the kinematic characteristics of DRF patients and explored the relationship between their clinical assessments and kinematic characteristics.

We analyzed 20 patients with DRFs after their surgeries. We recorded their finger-tapping using a magnetic sensor, and we calculated the velocity, magnitude, and movement-initiation hesitation. The patients’ pain intensity and fear of movement were assessed by a visual analogue scale and the Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH). To investigate the features of the patients who achieved only slight improvement, we compared the kinematic characteristics of the DRF patients in 2 subgroups: the “good improvement group” and the “slight improvement group” based on a cutoff value of the DASH score (>40) at 1 month postsurgery.

The DASH score at 30 days postsurgery was significantly correlated with hesitation at 1 day postsurgery (r = .66, P < .0071) and with velocity at 7 days (r = −.54, P < .0071). Our kinematic analyses revealed significant differences in velocity at 7 days postsurgery (P < .05) and in hesitation at 1 day postsurgery (P < .05) between the subgroups.

Since assessments using range-of-motion measurements or a questionnaire are not sufficient to evaluate a patient’s movement disorder, a kinematic analysis should be conducted for quantitative assessments.

While not studied for distal radius fractures, the effect of surgical timing on complication rate has been extensively analyzed in the treatment of pilon fractures. The primary aim of this study was to identify any effect surgical timing has on postoperative complication rates after surgical fixation of distal radius fractures in diabetic patients.

All patients who underwent surgical fixation of distal radius fractures at a single suburban academic hospital between 2012 and 2019 were reviewed. For each patient, demographics, comorbidities, injury details, fixation method, and postoperative complications were noted. The effect surgical delay, among other factors, had on complication rate in diabetic and nondiabetic patients was explored.

Overall, 124 diabetic and 371 nondiabetic distal radius fractures were included. While diabetics had a statistically higher rate of total complications (21.0 vs. 13.5%, P = .045) but similar major complications requiring surgery (P = .12), there was no difference in surgical delay between groups among patients who had total (P = .31) or major (P = .69) complications. Surgical timing was not a risk factor for total (P = .50) or major complications (P = .32) in diabetic fracture bivariate or multivariate analysis. Only younger age and higher energy injuries were significant risk factors for total complications in bivariate (P = .02, P = .03) and multivariate (P = .04, P < .05) analysis.

Complication rates after surgically stabilized distal radius fractures in diabetic patients are higher than in nondiabetic patients. However, this rate is not affected by surgical timing. Instead, surgeons should consider factors such as diabetic control in an effort to maximize outcomes and decrease complications.

Prognostic Level III

Hand infections caused by mycobacteria are relatively uncommon compared to infections caused by other pathogens; therefore, much of the available literature consists of case reports and limited case series. Broadly categorized into tuberculous and nontuberculous mycobacterial (NTM) infections, both tuberculous and NTM infections are typically insidious with long incubation periods and with the ability to remain dormant for prolonged periods.

We reviewed the most current literature on the epidemiology, presentations, treatment methods, and resistance patterns of mycobacterial infections of the hand focusing on the indications and outcomes of nonoperative as well as operative interventions.

The worldwide burden of tuberculosis remains high and while the overall rate of new diagnosis drug resistant tuberculosis has been on the decline some regions of the world have demonstrated staggeringly high resistance rates to first-line tuberculosis therapies. Signs and symptoms of mycobacterial hand infection are typically inconsistent, and highly dependent on the specific structures of the hand that are affected; therefore, these infections may mimic other infections of the hand like tenosynovitis, joint space infections, and cutaneous infections. The main stay of treatment remains antimycobacterial therapies including but not limited to rifampin, isoniazid, pyrazinamide, and ethambutol.

The complications associated with mycobacterial hand infections can be significant. Prompt evaluation, including a thorough history to evaluate for potential exposures to infectious sources, followed by appropriate antibiotic choice and duration, with surgical management as needed, is key to reducing the chance that patients experience lasting effects of the infection.

Complete extension of the thumb and activation of the extensor pollicis longus (EPL) tendon are fundamental to ensure maximum function. Many EPL repair techniques are described in the literature.

The authors present an alternative technique using the brachioradialis (BR) tendon. Thirty patients with injuries of the EPL tendon in zone 8 were studied. In all cases, neither direct suture repair nor traditional tendon transfer was possible.

Thumb extension was restored in all patients with satisfactory extension recovery. All patients achieved excellent extension; good functional results were observed in 2 cases, and in 1 case satisfactory results were achieved using the Geldmacher assessment and the Kapandji assessment. The overall results were rated as excellent, good, fair, or poor according to the Quick Disabilities of the Arm, Shoulder, and Hand Scale.

The BR tendon was suitable to treat all cases, in particular injuries occurring near Lister’s tubercle, due to its appropriate length for tenorrhaphy albeit with a short distal head.

The purpose of this study was to identify independent risk factors associated with an increased rate of surgical site complications after elective hand surgery.

This study is a retrospective review of all patients who underwent elective hand, wrist, forearm, and elbow surgery over a 10-year period at a single institution. Electronic medical records were reviewed, and information regarding patient demographics, past medical and social history, perioperative laboratory values, procedures performed, and surgical complications was collected. Surgical site complications included surgical site infections, seromas or hematomas, and delayed wound healing or wound dehiscence. A univariate analysis was then performed to identify potential risk factors, which were then included in a multivariate regression analysis.

A total of 3261 patients who underwent elective hand surgery and met the above inclusion and exclusion criteria were included in this study. The mean age was 57 years, with 65% female and 35% male patients. The overall surgical complication rate was 2.2%. Univariate analysis of patient factors identified male sex; number of procedures >1; history of drug, alcohol, or smoking use; American Society of Anesthesiologists (ASA) class III and IV; and serum albumin <3.5 mg/dL to be significantly associated with complications. However, multivariate regression analysis identified that only ASA class III and IV (odds ratio = 3.27) was significantly associated with surgical complications.

Patients classified as ASA class III or IV were identified to be at a significantly increased risk of complications following elective hand surgery. Health factors which triage patients into these 2 groups may represent potentially modifiable factors to mitigate perioperative risk in the elective hand surgery population.
