DE CARLI, Pablo et al. Artrodesis mediocarpiana: estudio de la evolucion clinico-radiologica con tres anos de seguimiento minimo. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2015, vol.80, n.4, pp.274-281. ISSN 1852-7434.

Objective: To determine the clinical and radiological outcomes of patients treated with midcarpal arthrodesis with a minimum follow-up of three years. Methods: Patients treated in our Service through midcarpal arthrodesis since May 1998 were studied. From a total of 27 patients, 11 wrists with a minimum follow-up of 3 years were included. Eight patients were men and three were women, with a mean age of 47 years (range 16-66) and an average follow-up of 6.7 years (range 3-15). The technique was 2 or 4 corner fusion with scaphoid resection plus distal radius graft. Pain using Visual Analog Scale, mobility, and grip strength were evaluated. QuickDASH scoring and control X-rays were performed. Results: Pain improved from a preoperative value of 5/10 at rest and 8/10 at activity to 0/10 and 2/10 after surgery, respectively. The lost motion with respect to the healthy side was flexo-extension 39%, radial deviation 15%, and ulnar deviation 31%. There were no changes in pronosupination and the postoperative QuickDASH score was 10. Force was 92% compared to the opposite side. Radiologically four patients didn´t show changes in radiolunate joint space; in the remaining, it was narrower. Two patients were reoperated on for nonunion with bone graft. Conclusions: Midcarpal fusion improves symptoms, retaining 61% of flexo-extension, 85% of the radial deviation, 31% of the ulnar deviation and 92% of the force.
