摘要

目的：趾长伸肌（EDL）和腓骨近端肌（FT）都表现出广泛的形态变化。方法：对一具70岁男性尸体进行常规解剖，以供研究和教学之用。结果：EDL肉质腹部明显缩小，而FT呈肥厚。EDL肌腱表现出非典型伸长，仅分叉成三个不同的滑动，插入第二、第三和第四趾的指背扩张。相比之下，FT肌腱非常发达，分为两个滑脱。外侧滑块附着在第五跖骨基部的背侧，而内侧滑块向远端延伸，融入第五趾趾的背侧扩张。结论：在涉及肌腱切口的损伤中，临床医生应考虑EDL的变化，以确保适当的肌腱修复。FT肌瓣和肌腱移植是矫正踝关节松弛和足下垂的常用方法。了解EDL和FT的变化对手术计划至关重要。

A rare unilateral variation of extensor digitorum longus and fibularis tertius muscles.

Purpose: Both the extensor digitorum longus (EDL) and fibularis tertius (FT) muscles exhibit a wide range of morphological variations.

Methods: A 70-year-old male cadaver was subjected to routine anatomical dissection for research and teaching purposes.

Results: The EDL had a markedly smaller fleshy belly, whereas the FT appeared hypertrophic. The EDL tendon displayed an atypical elongation and bifurcated into only three distinct slips, which inserted into the dorsal digital expansions of the second, third, and fourth toes. In contrast, the FT tendon was remarkably well-developed and divided into two slips. The lateral slip attached to the dorsal aspect of the base of the fifth metatarsal, while the medial slip extended distally to integrate into the dorsal digital expansion of the fifth toe.

Conclusion: In injuries involving tendon incisions, clinicians should consider EDL variations to ensure proper tendon restoration. The FT muscle flap and tendon grafts are commonly used to correct ankle joint laxity and foot drop. Understanding variations in the EDL and FT is crucial for surgical planning.

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
