Capitate sliding osteotomy combined with lunocapitate fusion for stage II/III scaphoid non-union advanced collapse.
Adding capitate sliding osteotomy to lunocapitate fusion left patients with less wrist disability.
Capitate sliding osteotomy combined with lunocapitate fusion for stage II/III scaphoid non-union advanced collapse.
Although lunocapitate fusion is currently the most prevalent and effective surgical approach for stage II/III scaphoid non-union advanced collapse (SNAC), clinical challenges such as suboptimal fusion rates and compromised wrist functionality remain unresolved.
This study aims to investigate the application of capitate sliding osteotomy combined with central and eccentric fixation techniques in lunocapitate fusion, with the dual objectives of enhancing fusion rates and enabling rigid fixation to facilitate early postoperative rehabilitation, thereby improving postoperative functional outcomes.
We retrospectively analyzed patients who underwent lunocapitate fusion combined with capitate sliding osteotomy (treatment group) and those who underwent lunocapitate fusion alone (control group) between 2016 and 2024.
disability score fell to near normal, far lower than fusion alone
51.57 ± 3.94-20.05 ± 3.61 in the control group ( p < 0.001).
5.38 ± 0.70-1.23 ± 0.25 in the control group ( p < 0.001).
82.54° ± 3.85°-107.25° ± 4.80° in the control group ( p < 0.001).
13.53 ± 2.94 kg to 25.56 ± 2.32 kg in the control group ( p < 0.001).
In this retrospective comparative study, the combination of capitate sliding osteotomy with lunocapitate fusion was associated with higher fusion rates and greater improvements in short-term functional outcomes compared with lunocapitate fusion alone for stage II/III SNAC.
This technique appears to be a promising option that may allow for earlier rehabilitation.
