Chronic lunotriquetral ligament injuries: arthrodesis or capsulodesis.

Lunotriquetral ligament ruptures were treated by arthrodesis or ligament reconstruction. The outcomes were retrospectively reviewed: 17 underwent an arthrodesis, 13 a reconstruction with a strip of the extensor retinaculum. In the arthrodesis group, nine were not satisfied; complications and re-operations were numerous; eight developed a pseudarthrosis. In the reconstruction group, eight were satisfied, five were not. Complications were less frequent and less severe.
