Arthroscopic debridement alone for intercarpal ligament tears

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Hand and Wrist Surgery

Background:

• Persistent wrist pain often results from intercarpal ligament tears.
• Scapholunate and lunotriquetral ligament injuries are common causes of wrist instability and pain.
• Current treatment options for these tears vary, with surgical intervention often considered.

Purpose of the Study:

• To evaluate the efficacy of arthroscopic debridement as a standalone treatment for complete and incomplete intercarpal ligament tears.
• To assess symptom resolution, functional improvement, and radiographic changes following arthroscopic debridement of scapholunate and lunotriquetral ligament tears.

Main Methods:

• Retrospective analysis of 43 wrists with isolated scapholunate or lunotriquetral ligament tears.
• All patients underwent arthroscopic debridement of torn ligament edges.
• Follow-up included clinical examination for symptom resolution and grip strength measurement, with radiographic assessment for instability.

Main Results:

• A majority of patients experienced symptom resolution or improvement: 66% for complete and 85% for incomplete scapholunate tears; 78% for complete and 100% for incomplete lunotriquetral tears.
• Postoperative grip strength improved by an average of 23%.
• No static intercarpal instability patterns were observed on follow-up radiographs.

Conclusions:

• Arthroscopic debridement alone can provide symptomatic relief for a majority of patients with intercarpal ligament tears.
• This minimally invasive approach appears effective for both scapholunate and lunotriquetral ligament injuries.
• Long-term outcomes regarding sustained pain relief require further investigation.
