[Trapezoid-metacarpal arthrodesis].
There is no ideal surgical indication for rhizoarthrosis of the trapezoid-metacarpal joint. Fusion using two screws or a screw and a pin allow solidification after minimal immobilization for 45 days with the thumb placed in front of the index. A 1 to 21 year follow-up (mean 68 months) of 30 hands showed 23 cases of arthrosis and 7 cases of polyarthritis. Overall results were good in 17 cases, acceptable in 8 and poor in 5. Pain relief was obtained or improved in 90% of the cases. Radiographically, pseudarthrosis was seen in 10%. No reoperations were required. Fusion is an alternative to other surgical approaches allowing pain relief and solid grip without the major problems related to prostheses.
