Abstract
Background
When performed alone, endoscopic carpal tunnel release and endoscopic cubital tunnel release are safe and effective surgical options for the treatment of carpal and cubital tunnel syndromes, respectively. However, there is currently no literature that describes the performance of both procedures concomitantly. We describe the results of 17 cases in which dual endoscopic carpal and cubital tunnel releases were performed for the treatment of concurrent carpal and cubital tunnel syndromes.
Methods
A retrospective review of all patients in a single surgeon practice that presented with concomitant ipsilateral carpal and cubital tunnel syndromes was performed. Within an 8-month period, 17 patients had undergone 19 concomitant ipsilateral endoscopic carpal and cubital tunnel releases after failing conservative treatment. Pre- and postoperative measurements included subjective numbness/tingling; subjective pain; manual muscle testing of the abductor pollicis brevis (APB), intrinsics, and flexor digitorum profundus (FDP); static two-point discrimination; quick-DASH (Disabilities of the Arm, Shoulder and Hand) scores; grip strength; chuck pinch strength; and key pinch strength. Complete data are available for 15 patients and 17 total procedures.
Results
Thirteen male and four female patients (average age of 50.5) underwent dual endoscopic cubital and carpal tunnel release. Two patients were lost to follow-up and eliminated from data analysis. Pre- and postoperative comparisons were completed for median DASH scores, grip strength, chuck pinch strength, and key pinch strength at their preoperative visit and at 12 weeks. DASH scores improved significantly from a median of 67.5 to 16 (p =0.002), grip strengths improved from 42 to 55.0 lbs (p =0.30), chuck pinch strengths improved significantly from 11 to 15.5 lbs (p =0.02), and key pinch strengths increased significantly from 13 to 18 lbs (p = 0.003). Average static two-point discrimination decreased from 5.9 to 4.8 mm. In terms of pain, 82 % of patients had complete resolution of pain, and the remaining 18 % experienced pain only with strenuous activity. In terms of numbness/tingling, 100 % of patients had complete resolution of median nerve symptoms; 88 % of patients had substantial improvement of numbness and tingling symptoms, and 12 % had residual ulnar nerve symptoms. In terms of muscle strength, 92 % of patients had improvement to 5/5 APB strength, while 100 % of patients had improvement to 5/5 intrinsic and FDP strengths. Two minor complications occurred, including one superficial hematoma and one superficial cellulitis.
Conclusions
Preliminary data demonstrate that dual endoscopic carpal and cubital tunnel release is a safe and effective treatment option for patients who present with concurrent cubital and carpal tunnel syndromes recalcitrant to non-surgical management. Postoperative results and complications are comparable to endoscopic carpal and cubital tunnel releases performed alone.
