Background: The objective of the current study was to retrospectively examine the morphological magnetic resonance imaging (MRI) characteristics of the gluteus maximus of buttock augmentation at levels of predetermined anatomic points.
Methods: The present study was a retrospective cross-sectional study. Adult women who underwent high-quality MRI scanning at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to January 2021 were included in this work. The transverse MRI data measured at the inferior point of the sacroiliac joint, just above the femoral head, and at the ischial tuberosity were collected and statistically analyzed.
Results: Fifty-two cases (104 sides of female gluteus maximus) were included in the final analysis. The A point (surgery starting point) were 54.4±6.34 mm, 54.91±5.57 mm, and 73.91±5.57 mm away from the posterior midline at the level of inferior point of the sacroiliac joint, just above the femoral head, and at the ischial tuberosity, respectively. Accordingly, the thickness of the muscle at these locations was 16.0±4.17 mm, 23.4±4.40 mm, and 24.6±7.58 mm, respectively. The diameter of the implant did not exceed 14.18±1.22 cm. In addition, the gluteus maximus at the lowest point of the sacroiliac joint and above the femoral head exhibited an arc structure, which needs to be tilted to the deep plane during separation.
Conclusions: Dissimilar from previous experience of blind dissection, the gluteus maximus muscle can be more scientifically and reasonably dissected using the indexes for gluteus augmentation supplied in this study.

Tensor Fasciae Latae and Gluteus Maximus Muscles: Do They Contribute to Hip Abduction?

Hip abductors are essential for hip function. To understand abduction weakness, it is important to know which muscles contribute to abduction force. Our aim was to investigate the effects of an experimentally induced weakness of the different muscles (tensor fasciae latae [TFL], gluteus medius and minimus (Gmed/min), gluteus maximus [Gmax]) on the abduction force.

Glioma-associated oncogene (-altered mesenchymal tumors are a newly described entity of neoplasms with very few case reports published in the literature. -altered neoplasms have a moderate degree of variability as they are seen in a broad range of anatomic sites and amongst people of all ages. A common feature that most -altered tumors share is the histologic makeup of monomorphic ovoid cells organized in distinct nests and an arborizing vascular blood supply.

Background: The muscles that encase the hip serve a crucial role in both joint stability and functional efficacy, and as developmental dysplasia of the hip (DDH) progresses, the surrounding musculature may undergo specific adaptations that reduce joint stability, thereby exacerbating dislocation. Yet, the exact nature of changes in muscle morphology and quality remains inadequately investigated. This study aimed to compare magnetic resonance imaging (MRI) evaluations of the iliopsoas and other hip flexor and extensor muscles in children with unilateral DDH before and after treatment.

The perianal abscess is a common emergency surgical presentation. While in most cases simple drainage suffices, occasionally the abscess can track deeply presenting a management challenge. We describe the case of a complex circumferential horseshoe ischioanal abscess with extension below the levator ani through the greater sciatic notch and into the left gluteal region, with the collection involving the intergluteal space and gluteus maximus.

Introduction: The Gibson approach, used in hip-preserving surgery, is intermuscular and develops the space anteriorly to the gluteus maximus. Reliable anatomical landmarks for the development of this interval do not exist, but the interval is marked by perforating vessels (PV) of the inferior gluteal artery. The aim of this study was to provide reference values for the relationship between palpable anatomical landmarks on the femur/pelvis and the anterior border of the gluteus maximus using CT scans of the proximal femur.
