Combined Transosseous and Capsular Repair for TFCC Tears with DRUJ Instability-A Step Toward Comprehensive Joint Stabilization.

Abstract

Triangular fibrocartilage complex (TFCC) tears involving the foveal attachment are a known cause of distal radioulnar joint (DRUJ) instability. While transosseous repair of the deep TFCC fibers is a widely accepted technique for restoring DRUJ instability, persistent instability remains a clinical challenge in a subset of patients. Combining transosseous repair with volar and dorsal capsular repair is an important technique to consider when treating Atzei Class 2 TFCC tears. This evolving approach reflects a more comprehensive appreciation of the TFCC as a complex stabilizing unit, rather than an isolated ligamentous structure.
