Abstract

Introduction

The purpose of this study was to characterize the morphological variations in the quadratus femoris muscle (QF) and to create an anatomical classification that could be used in the planning of surgical procedures in this area, radiological imaging, and rehabilitation.

Materials and methods

Ninety-two lower limbs from 46 cadavers, fixed in 10 % formalin solution, were examined.

Results

The QF muscle was present in all specimens. According to morphology, the QF muscle was classified into three types. The most common type was Type I, characterized by one muscular belly (78.3 %), while the second most common type was Type II, characterized by two bellies, was observed in 17.4 % of cases. The rarest type was Type III. It was characterized by three bellies and was found in 4.3 % of the cases.

Conclusions

The current classification system on quadratus femoris morphological variability is novel. Morphological variants may contribute to clinical issues, such as the ischiofemoral impingement syndrome, that could arise from type I quadratus femoris. Hence, the current study may be applicated to planning surgical procedures, imaging, and rehabilitation.

股四头肌解剖图：我们了解一切吗？

引言这项研究的目的是描述股四头肌（QF）形态变化的特征，并建立一种解剖学分类，以用于该部位的外科手术规划、放射成像和康复。根据形态，QF 肌肉可分为三种类型。最常见的类型是 I 型，其特征是有一个肌腹（78.3%），第二常见的类型是 II 型，其特征是有两个肌腹，占 17.4%。最罕见的类型是 III 型。结论目前关于股四头肌形态变异的分类系统很新颖。形态变异可能会导致临床问题，如I型股四头肌可能引发的股骨峡部撞击综合征。因此，本研究可应用于外科手术、成像和康复计划。
