Abstract

Background: The objective of the study is to characterize factors associated with radiographic union and pain at final follow-up in surgical repair of scaphoid nonunion.

Methods: Patients who underwent scaphoid nonunion repair at our institution between 2005 and 2024 were retrospectively reviewed. Demographic and surgical factors were abstracted. Preoperative, immediate postoperative, and final follow-up scapholunate (SL) angles were measured. Radiographic union (>75% healing) and patient-reported pain at final follow-up were assessed. Associations between SL angle measurements, patient characteristics, and surgical variables with union and pain were evaluated using unpaired t tests and χ² tests.

Results: Fifty-five patients met inclusion criteria with persistent nonunion occurring in 17 patients (30.1%). Patient sex was significantly associated with union (P = .045) but not pain at final follow-up (P = .399). All other demographic factors (smoking status, diabetes, prior surgery) and surgical factors (fracture location, surgical approach, implant type, graft type, and use of adjunct Kirschner-wire) were not significantly associated with union or pain at final follow-up (all P > .05). Among SL angle measurements, only a lower final follow-up SL angle was significantly associated with higher union rates (P = .038). No SL angle measurement was associated with pain at follow-up (all P > .05).

Conclusions: Patient sex was associated with union. No other demographic or surgical variables were associated with union or pain at final follow-up. A lower SL angle at final follow-up was independently associated with successful union, suggesting that correction of carpal alignment may contribute to improved healing in scaphoid nonunion repair.

成人舟骨不连手术中舟月骨角度矫正对影像学愈合的影响：一项机构回顾性队列研究。

背景：本研究的目的是在舟状骨骨不连手术修复的最后随访中描述与影像学愈合和疼痛相关的因素。方法：回顾性分析我院2005年至2024年间舟骨不连修复的患者。人口统计学和外科因素被抽象化。测量术前、术后即刻和最后随访时舟月骨（SL）角。在最后随访时评估放射学愈合（bbb75 %愈合）和患者报告的疼痛。采用非配对t检验和χ2检验评估SL角测量值、患者特征和手术变量与愈合和疼痛之间的关系。结果：55例患者符合纳入标准，17例患者（30.1%）出现持续性骨不连。患者性别与愈合（P = 0.045）显著相关，但与最终随访时的疼痛无关（P = 0.399）。所有其他人口统计学因素（吸烟状况、糖尿病、既往手术）和手术因素（骨折位置、手术入路、植入物类型、移植物类型和辅助克氏针的使用）与最终随访时的愈合或疼痛无显著相关（均P < 0.05）。在SL角测量中，只有较低的最终随访SL角与较高的愈合率显著相关（P = 0.038）。在随访时，测量SL角与疼痛无相关性（均P < 0.05）。结论：患者性别与骨愈合有关。在最后随访时，没有其他人口统计学或手术变量与愈合或疼痛相关。最后随访时较低的SL角与愈合成功独立相关，表明腕关节对中矫正可能有助于改善舟骨不愈合修复。
