Brief summary

Trapezometacarpal protheses are implanted for patients with trapezometacarpal arthritis. Having a pre-operative thumb adduction angle of less than 25 degrees with hyperextension, meaning a Z-deformity are somehow a reason to go for another surgical treatment: trapezectomy with ligament reconstruction. This study will aim at analyzing the results of another surgical treatment which is the trapezometacarpal arthroplasty in this type of deformities.
