Arthroscopic algorithm for acute traumatic triangular fibrocartilage complex (TFCC) tears.

Abstract

The triangular fibrocartilage complex (TFCC) is crucial for stability and acts as a shock absorber and load transmitter at the distal radioulnar joint (DRUJ). It is often injured in wrist trauma, particularly in young athletes. Clinical assessment involves patient history, physical examination, and imaging modalities like MRI, with wrist arthroscopy as the gold standard for diagnosing TFCC tears. Multiple classification systems categorize TFCC tears based on location and arthroscopic appearance, guiding treatment decisions. Surgical options are recommended for tears refractory to conservative management or severe tears. Despite numerous arthroscopic treatments available in the literature, this article aims to simplify the approach. It presents the authors' surgical algorithm for managing acute traumatic TFCC tears arthroscopically. The choice of technique depends on the lesion's location, with various options for peripheral and foveal tears. Post-operative rehabilitation is crucial for optimal recovery. This article provides a comprehensive review of acute traumatic TFCC injuries, covering anatomy, classification, assessment, and treatment options. Emphasis is placed on accurate diagnosis and appropriate arthroscopic management through a structured approach.
