Metatarsophalangeal arthroscopy of the hallux

a description of a modified technique

Abstract

Objective: This study sought to describe a modified arthroscopic technique in which a traction device with a horizontal vector and nylon mesh are used to allow continuous and uniform distraction without requiring an assistant surgeon to perform manual traction. Methods: Nine patients (seven females and two males; mean age 31.8 [30-52] years) with an indication for treatment of this joint who had been diagnosed with different pathologies, including synovitis, hallux vagus, and hallux rigidus, were selected and underwent arthroscopy of the first metatarsophalangeal joint using this modified technique. Results: Patient evaluations determined using the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale were recorded before and after surgery. The mean scores before and after the procedure were 43.66 (32-55) and 95.22 (90-8), respectively. No scars or joint complications were observed at a six-month follow-up, and all subjects experienced rapid recovery and quickly returned to daily functions. Conclusion: Similarly to conventional arthroscopy of the metatarsophalangeal joint, the modified technique produced satisfactory surgical outcomes; moreover, this technique reduced surgical time and improved the surgeon’s autonomy by obviating the need for an assistant surgeon to perform traction. Level of Evidence IV; Therapeutic Studies; Case Series.
