This study examined the occurrence rate of ten lower extremity anatomical variants occurring over a 6-year period from 1988 to 1994 in a sample range of 166 to 279 cadavers at the University of Osteopathic Medicine and Health Sciences. Literature review of these anomalies shows similar findings for all presented structures with the exception of two. The peroneus quartus muscle was found to be significantly less prevalent than previous studies have indicated. This difference may be attributed to the larger sample size used in this study or differences of interpretation of the definition of the peroneus quartus muscle. Additionally, the flexor digitorum brevis tendon to the fifth digit was found to be absent much more than Sarrafian reports in a total sample size of 926. The importance of these anatomical variants, both in surgery and while using advanced diagnostic imaging such as computed tomography and magnetic resonance imaging, should be realized by the podiatric physician. Awareness of these variants will decrease confusion when considering treatment options.
本研究调查了1988年至1994年这6年间，在整骨医学与健康科学大学166至279具尸体样本范围内出现的10种下肢体解剖变异的发生率。对这些异常情况的文献综述显示，除了两种情况外，所有呈现结构的研究结果都相似。发现第四腓骨肌的发生率明显低于以往研究表明的情况。这种差异可能归因于本研究中使用的样本量更大，或者对第四腓骨肌定义的解释存在差异。此外，在总共926个样本中，发现小指短屈肌腱缺失的情况比萨拉菲安报告的要多得多。足病医生应认识到这些解剖变异在手术以及使用计算机断层扫描和磁共振成像等先进诊断成像时的重要性。了解这些变异将减少在考虑治疗方案时的困惑。
