RESUMEN
Partial trapeziectomy with suspension ligamentoplasty is a commonly performed treatment of thumb osteoarthritis. Nevertheless, the post-operative recovery remains long and critical reason for which different modifications of the surgical technique have been proposed. To compare two suspension ligamentoplasty techniques, one with a mitek anchor and another without, a retrospective study of 55 consecutive operated patients was performed. A detailed clinical analysis of pain, function and a radiologic assessment of the trapeziometacarpal space were performed. Mitek anchor fixation was associated with a shorter convalescence period. However, in spite of an improved radiological maintenance of the scaphometacarpal space, mitek anchor fixation was associated with an impaired postoperative function and residual pain when compared with the conventional suspension ligamentoplasty procedure. Patient's satisfaction was comparable in both groups. In our series stabilization of the suspension ligamentoplasty procedure by the insertion of a mitek anchor did not bring the hoped benefits to the patients with a trapeziometacarpal arthritis.
