Trapezium fractures rarely present as isolated fractures and warrant anatomical fixation to minimize post-traumatic arthritis. Fixation techniques reported include open approach to trapezium fracture and fixation, percutaneous fixation under image intensifier guidance or percutaneous arthroscopic fixation under gravitational traction. We have reported a novel method of percutaneous fixation of a trapezium Walker type IV coronal split fractures under gravitational traction and per-operative image intensifier guidance. Two percutaneous headless differential pitch screws were used for fixation, which was off-loaded using an inter-metacarpal K-wire. Patient was discharged on the same day with a light-weight cast. The fixation yielded acceptable reduction of the articular surface as confirmed by radiographs. The cast and off-loading K-wire were removed at four weeks post-surgery and hand therapy was commenced. 3-month review showed optimal radiological healing with excellent return to function without pain. In conclusion, using gravitational traction can allow percutaneous fixation of trapezium fractures with excellent results and also make an otherwise complex procedure simpler. LEVEL OF EVIDENCE: IV.
舟骨骨折很少作为孤立性骨折出现,需要进行解剖固定以最大程度地减少创伤后关节炎。报道的固定技术包括切开入路舟骨骨折固定、影像增强器引导下经皮固定或重力牵引下经皮关节镜固定。我们报告了一种在重力牵引和术中影像增强器引导下经皮固定舟骨 Walker Ⅳ型冠状分裂骨折的新方法。使用 2 枚经皮无头差速螺钉进行固定,使用掌骨间 K 线卸载。患者当天出院,用轻便石膏固定。X 线片证实固定后关节面的复位效果可接受。术后 4 周去除石膏和卸载 K 线,并开始手部治疗。3 个月的随访显示,影像学愈合良好,功能恢复极佳,无疼痛。总之,使用重力牵引可以实现舟骨骨折的经皮固定,效果极佳,而且使原本复杂的手术变得更简单。证据水平:IV 级。
