To investigate the application of capitate sliding osteotomy combined with lunocapitate fusion to enhance fusion rates and improve postoperative functional outcomes in patients with stage II/III scaphoid non-union advanced collapse (SNAC).
Key Findings:
DASH scores improved significantly in the treatment group from 53.91 ± 5.75 to 10.73 ± 5.52 compared to the control group's improvement from 51.57 ± 3.94 to 20.05 ± 3.61 (p < 0.001).
VAS pain scores decreased significantly in the treatment group from 5.72 ± 0.87 to 0.71 ± 0.22 versus the control group's decrease from 5.38 ± 0.70 to 1.23 ± 0.25 (p < 0.001).
Wrist flexion–extension ROM improved from 80.49° ± 3.36° to 113.74° ± 3.76° in the treatment group compared to 82.54° ± 3.85° to 107.25° ± 4.80° in the control group (p < 0.001).
Grip strength increased from 12.24 ± 1.47 kg to 29.27 ± 2.32 kg in the treatment group versus 13.53 ± 2.94 kg to 25.56 ± 2.32 kg in the control group (p < 0.001).
Interpretation:
Limitations:
Retrospective study design may introduce selection bias.
Limited sample size in both treatment and control groups.
Ten-year observational data showed lower disease activity and functional disability coinciding with broader use of biologic and targeted synthetic therapies.
