Trapeziometacarpal distraction arthroplasty is a surgical technique for the treatment of trapeziometacarpal arthrosis. It consists of distracting the first metacarpal and then anchoring it in suspension to the second metacarpal by means of a tendon graft. Both a reduction of the subluxation of the base of the first metacarpal and an opening or distraction of the trapeziometacarpal joint, with a clear decrease in the forces of attrition on its joint surfaces, are thereby obtained. Compared with the traditional techniques of arthroplasty, this technique avoids trapeziectomy; it is therefore less destructive and is quicker and easier to carry out. It appears to be equally effective regarding pain, correcting the deformity, and recovering grip strength.
大多角骨-第一掌骨撑开关节成形术是一种治疗大多角骨-第一掌骨关节病的外科技术。该技术包括撑开第一掌骨，然后通过肌腱移植将其悬吊固定于第二掌骨。如此一来，既减少了第一掌骨基底的半脱位，又撑开了大多角骨-第一掌骨关节，同时明显降低了关节面的磨损力。与传统的关节成形术相比，该技术避免了大多角骨切除术；因此，其破坏性较小，实施起来更快、更容易。在缓解疼痛、矫正畸形和恢复握力方面，该技术似乎同样有效。
