Fatty infiltration of the gluteus medius and minimus muscles: volumetric analysis of both hips in patients with unilateral greater trochanteric pain syndrome using 2-point-Dixon MRI.

ABSTRACT:

Objectives

To investigate normal and pathologic values of fatty infiltration (FI) and muscle volume through volumetric quantification of the main hip abductors of patients with unilateral greater trochanteric pain syndrome (GTPS) using 2-point-Dixon MRI.

Materials and methods

Patients prospectively underwent MRI of both hips: FI of the gluteus minimus (Gmin) and medius (Gmed) muscles were quantified by volumetric fat fractions (3D FF) using 2-point-Dixon MRI. Whole (WMV) and lean muscle volumes (LMV) were calculated for both muscles. 3D FF and volumes were compared between asymptomatic and GTPS hips, using the Wilcoxon signed-rank test. Gender-specific differences were assessed using the Mann-Whitney U test.

Results

Forty-one patients (mean age 65.0 ± 13.6 years, 27 f
