Interposition-suspension arthroplasty with allografts for trapezio-metacarpal joint osteoarthritis treatment: evolution and long term results. Cir. plást. iberolatinoam.

Background and Objectives. The trapezium-metacarpal (TMC) joint has a special anatomy that is modified when the osteoarthritis come in. Of all the techniques, we propose an interposition- suspension arthroplasty with criopreserved allografts that we think that reproduces truly the joint movement. Methods. We submit a prospective study with 103 patients that suffered osteoarthritis of de TMC joint and were treated with this technique of arthroplasty. Pain, ability for work or daily live activities were valued to evaluate this technique and its remaining in time. Results. An improvement in pain and in their daily activities wasobtained following arthroplasty, and these results were kept on time even in patients with as a long follow up as 9 years. Complications were solved in all cases without sequelae. Joint movement is similar to the movement of two rings interlocked, which allows the same grades of movement than the TMC joint. Conclusions. The submitted technique evidence the movement of a coil section allows recover all the movement to the joint. This technique could be used in any stage of the disease and retain its results along the time.
