SUMMARY
We performed a systematic review to find out the safety and efficacy of various procedures for isolated scaphotrapeziotrapezoid osteoarthritis. Eleven articles were included. The most common procedure was arthroplasty with pyrocarbon implant (28%), followed by resection of distal pole of scaphoid with proximal trapezium and trapezoid resection (18%). The other procedures included trapeziectomy with ligament reconstruction and tendon interposition (LRTI) (14%), arthroscopic resection of distal scaphoid (11%), trapezium and trapezoid resection with LRTI (10%) and arthrodesis (10%).Complications were noted in 18 (15%) patients. The most common complication (7.5%) was asymptomatic dorsal intercalated segmental instability (DISI) followed by dislocation of the pyrocarbon implant (3%). Fusion resulted in decreased range of motion and grip strength. The distal scaphoid resection was related to high rate of DISI. The dislocation of pyrocarbon implant is avoidable with good surgical technique. Arthroplasty with pyrocarbon implant may be the first choice in younger patients.
