title: Treatment of scaphotrapezio-trapezoid arthritis.
abstract: Arthritis of the scaphotrapeziotrapezoid (STT) joint presents with deep thenar eminence and thumb basilar pain and is often coexistent with carpometacarpal arthritis of the thumb. Conservative treatment includes splinting and corticosteroid injections. Operative treatment consists primarily of fusion of the STT joint, although alternatives include trapeziectomy, fibrous arthroplasty, and prosthetic replacements. When STT arthritis is coexistent with carpometacarpal arthritis, excision of the trapezium and proximal 2 mm of trapezoid has been recommended. Complications of surgery include pericarpal arthrosis, superficial radial nerve injury, and nonunion.
