Abstract

[Purpose] Few previous studies have delimitated the palpation zone of the gluteus medius muscle with a focus on its fiber bundles. The purpose of this study was to clarify the morphological characteristics of the gluteus medius muscle using an anatomical approach, and to define its proper palpation zone. [Participants and Methods] In this study, we evaluated thirteen halves of the pelvic region in seven formalin-fixed cadavers. We identified the borders between the iliotibial band and gluteus medius muscle, and between the gluteus medius and gluteus maximus muscles, on the iliac crest. Furthermore, we quantified the border points of the gluteus medius' fiber bundles and observed its anatomical and morphological characteristics. [Results] We identified two fiber bundles in the gluteus medius muscle, an anterior and a posterior fiber bundle, and detected that a portion of the posterior fibers was located subcutaneously. [Conclusion] We propose that the region where the posterior fibers of the gluteus medius muscle are located subcutaneously is an appropriate zone for the palpation of this muscle.

Diagram of the zone where the posterior GMed fibers can be palpated subcutaneously (right lower limb). The posterior GMed fibers should be palpated slightly distal to the iliac crest (shaded area) between 62% and 83% of the iliac crest length, which is 100% of the length from the ASIS to the PSIS. Note that the iliac crest length is not the linear distance between ASIS and PSIS, but the length that follows the curve of the iliac crest.
