Capitate sliding osteotomy combined with lunocapitate fusion for stage II/III scaphoid non-union advanced collapse

1

Lunocapitate fusion is the most common surgical method for stage II/III scaphoid non-union advanced collapse, but faces challenges like low fusion rates.
2

This study analyzed outcomes of capitate sliding osteotomy combined with lunocapitate fusion versus lunocapitate fusion alone over a follow-up period of 24 months.
3

The treatment group showed significant improvements in DASH scores, VAS pain scores, wrist ROM, and grip strength compared to the control group.
4

All patients in the treatment group achieved solid fusion, indicating the effectiveness of the combined surgical approach.
5

The combination technique may enhance fusion rates and functional outcomes, suggesting a potential advancement in treating stage II/III SNAC.
