Treatment of TFCC Tears with Surgical Intervention

Surgical Techniques and Post-Operative Care

Arthroscopic foveal repair with suture anchor is preferred for Palmer 1B peripheral tears with disrupted deep fibers/foveal detachment, as it restores anatomic TFCC attachment to the foveal insertion site, which is critical for DRUJ stability, and allows concurrent treatment of associated injuries 1
Immobilize forearm rotation for 4 weeks post-operatively in neutral rotation, and wrist immobilized in neutral position, to ensure proper healing after surgical repair 1
Gentle active wrist motion begins at 4 weeks, strengthening exercises at 8-12 weeks, and return to heavy tasks and sports at minimum 3 months, to gradually restore function and prevent re-injury 1
Radiographic follow-up, including radiographs at 3 weeks post-operatively and additional imaging at immobilization cessation, is necessary to confirm healing and assess the need for further intervention 1

The American College of Radiology recommends MR arthrography for its better diagnostic accuracy than standard MRI for TFCC tears and associated ligament injuries, when conservative treatment fails and surgery is being considered 2
3.0T MRI without contrast has a sensitivity of 63-100% and specificity of 42-100% for TFCC tears, providing a useful diagnostic tool, although with variable accuracy 2
CT arthrography is superior to MRI and similar to MR arthrography for TFCC lesions, offering an alternative imaging modality, according to the Journal of the American College of Radiology 3, 4
Dorsal sensory branch of ulnar nerve (DSBUN) neuroapraxia occurs in approximately 10% of cases, with full spontaneous recovery expected, highlighting the importance of careful surgical technique and post-operative monitoring 1
Immobilization-related complications, such as skin irritation and muscle atrophy, occur in 14.7% of cases, but are generally minor, and can be mitigated with proper immobilization and rehabilitation protocols 1
