RESUMO
OBJECTIVE: Creation of a pain-free, flexible and stable (pseudo) joint between the carpus and the base of the 1st metacarpal bone. INDICATIONS: Painful carpometacarpal (CMC)I joint due to primary or secondary osteoarthritis, CMCI instability. CONTRAINDICATIONS: Carpal instability, local infection, tumors. SURGICAL TECHNIQUE: Resection of the trapezium (and of the arthritic joint surfaces in CMCI and STT [scaphoid-trapezium-trapezoid-joint]), stabilization of the base of the 1st metacarpal bone by suspension with a distally pedicled strip of the flexor carpi radialis tendon or variants thereof. POSTOPERATIVE MANAGEMENT: Immobilization in a splint for 3-5 weeks, followed by hand therapy. RESULTS: Worldwide for almost 40 years, regardless of the exact technique, almost always (90%) significant pain reduction, increased strength in the grip and slightly less in the pinch grip, very good mobility, 85-95% very satisfied patients and very good long-term results.
