Clinical Report: Capitate Sliding Osteotomy with Lunocapitate Fusion for SNAC

Overview

This study evaluates the effectiveness of capitate sliding osteotomy combined with lunocapitate fusion in patients with stage II/III scaphoid non-union advanced collapse (SNAC). Results indicate significantly improved fusion rates and functional outcomes compared to lunocapitate fusion alone.

Background

Scaphoid fractures are common wrist injuries that can lead to non-union and subsequent scaphoid non-union advanced collapse (SNAC), resulting in debilitating wrist arthritis. Current surgical options for stage II/III SNAC, such as lunocapitate fusion, have limitations including suboptimal fusion rates and compromised wrist functionality. Addressing these challenges is crucial for improving patient outcomes.

Data Highlights

Key Findings

• The treatment group showed significant improvement in DASH scores postoperatively compared to the control group (p < 0.001).
• VAS pain scores decreased significantly in the treatment group compared to the control group (p < 0.001).
• Wrist flexion–extension range of motion improved significantly in the treatment group (p < 0.001).
• Grip strength increased significantly in the treatment group compared to the control group (p < 0.001).
• All patients in the treatment group achieved solid fusion.

Clinical Implications

The combination of capitate sliding osteotomy with lunocapitate fusion may enhance fusion rates and functional recovery in patients with stage II/III SNAC. This approach could facilitate earlier rehabilitation and improve overall patient outcomes.

Conclusion

Capitate sliding osteotomy combined with lunocapitate fusion demonstrates promising results in improving fusion rates and functional outcomes for patients with stage II/III SNAC. Further studies may be warranted to validate these findings.
