Trapeziectomy, Partial Trapezoidectomy, and Abductor Pollicis Longus Dual Loop Ligament Reconstruction for Advanced Basal Joint Arthritis: Long-Term Outcome of 150 Cases.

Background: Although hand surgeons usually concur that arthroplasty is indicated for disabling basal joint arthritis, controversy persists regarding the preferred surgical methods. This article describes a novel technique of trapezial excisional arthroplasty with partial trapezoidectomy and abductor pollicis longus (APL) dual ligament reconstruction, and reports the long-term results of 150 cases. Based on this experience, we hypothesize that this technique is a reliably effective and durable surgical option for basal joint arthritis.
