Arthroscopic Resection of Tarsal Coalitions Via an Ultrasonic Bone Scalpel: A Case Report and Feasibility Study

Objective. This study aimed to evaluate the efficacy and feasibility of arthroscopic resection of tarsal coalitions via an ultrasonic bone scalpel. Methods. A retrospective analysis was conducted on a 29-year-old male patient suffering from persistent pain due to a tarsal coalition. The patient underwent arthroscopic resection of the tarsal coalition via an ultrasonic bone scalpel, followed by a 3-month postoperative follow-up. Intraoperative blood loss and operative time were recorded. Postoperative outcomes were assessed via X-ray, computed tomography (CT), and magnetic resonance (MR) images to evaluate the completeness of the resection and soft tissue recovery. Pain levels and functional recovery were evaluated via the visual analog scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, respectively. Complications were also documented. Results. The surgery was successfully completed without nerve or vascular injury, with minimal blood loss (~5 mL) and a total operative time of 45 minutes. At the 3-month follow-up, the patient’s VAS pain score improved significantly from 7 preoperatively to 1 postoperatively. The AOFAS score increased from 65 to 90. The CT scans confirmed the complete resection of the tarsal coalition, with no recurrence observed. The MR images revealed no significant vascular or neural injury. The patient was satisfied with the surgical outcome, and no complications were reported. Conclusion. Arthroscopic resection of tarsal coalitions via an ultrasonic bone scalpel is feasible and promising. This procedure significantly improves pain symptoms and ensures functional recovery without causing notable damage to surrounding soft tissues.
