Abstract

Background The flexor hallucis longus (FHL) muscle is crucial in fine motor control of the great toe but the muscle is often sacrificed in free fibula flap (FFF) reconstruction. The aim of this study was to compare great toe movement between complete and partial FHL resection during FFF harvest to see if FHL can be left behind (without undergoing fibrosis) in situ when bulk is not required at the recipient site. Methods A prospective, cross-sectional, observational study was performed including patients undergoing FFF harvest over a 2-year period. Movement of great toe interphalangeal joint was recorded of operated and unoperated legs in patients undergoing partial and complete FHL harvest and data analyzed. Results There was a statistically significant ( p < 0.05) difference between the two groups of patients. Conclusion FHL can be safely left in situ in patients not requiring bulk at the recipient site as blood supply, nerve supply, and muscle function are not compromised in partial FHL harvest. Further image-based and dye-based studies are warranted.

游离腓骨瓣完全和部分切除屈拇肌后大脚趾活动度的比较研究

背景屈拇长肌（FHL）对大拇趾的精细运动控制至关重要，但在游离腓骨瓣（FFF）重建中往往会牺牲这块肌肉。本研究的目的是比较游离腓骨皮瓣采集过程中完全切除和部分切除拇长屈肌后大拇趾的运动情况，以了解当受体部位不需要大块肌肉时，能否在原位保留拇长屈肌（不发生纤维化）。方法进行了一项前瞻性横断面观察研究，研究对象包括两年内接受 FFF 切除术的患者。记录了部分和完全切除 FHL 的患者手术腿和未手术腿的大拇趾指间关节活动情况，并对数据进行了分析。结果在部分切除 FHL 的患者中，由于血液供应、神经供应和肌肉功能不会受到影响，因此在不需要在受体部位进行大块切除的患者中，FHL 可以安全地留在原位。有必要进一步开展基于图像和染料的研究。
