TMC arthrodesis is an effective alternative to LRTI procedure for patients with high physical demand. Fusion of the TMC articulation proved to be a reliable surgery with good long term results, different methods of fixation have been described in the literature The main problem of the arthrodesis technique is the non-union and hardware failure, although non-union not always are symptomatic(1). Kazmer et al, compared 14 patients treated with modified arthrodesis versus 22 LRTI patients, and found 25% greater pinch strength in fusion group, as well as similar range of motion, the non-union rate was of 7 % (16). Non-union rates in literature are on average 8% to 21% (7).
