Artrosis de la articulación trapecio-metacarpiana. Tratamiento quirúrgico con resección del trapecio y reconstrucción con tendosuspensión del abductor pollicis longus

Abstract

Trapeziometacarpal joint osteoarthritis causes pain in the thumb, usually around the fifth decade, and with a prevalence of 25%. The deep anterior oblique ligament, the intermetacarpal ligament and the dorso-radial ligament play an important role in the stability of the joint. Materials and methodsThe results with resection of the trapezium and ligamentoplasty with abductor pollicis longus (APL) are presented in a series of cases.Two techniques were used, with one group with resection of the trapezium plus suspension arthroplasty with the APL (technique described by Brunelli), and another group with resection of the trapezium and a new suspension arthroplasty with the APL with the flexor carpi radialis. ResultsA total of 21 hands were operated on in each group, with minimum follow-up of 12 months. Pain, mobility and satisfaction were evaluated. The results were similar in both groups, with decreased pain (EVA) from between 8 and 9 to less than 1, with good mobility, and all the patients were satisfied with the results. DiscussionDifferent studies show that there are no differences between resection only of the trapezium or combined with ligament reconstruction and / or tendon interposition. The trapezoidal space decrease is almost equal in all groups, and did not correlate with the strength of the thumb.In this study, good results were achieved in both groups in terms of the reduction in pain and mobility, and similar to an earlier group treated with Artelon. These results support the hypothesis that either technique provides good results, thus we recommend using the simplest according to patient needs.
