“…The purposes of our study were to evaluate the effect of hip abductor muscle strength on hip function, to validate the utility of our CT-based analysis for the quantification of muscle volume and muscle degeneration of GMED, and to assess factors that affect hip abductor strength in patients with unilateral hip OA. Reduction of muscle volume and degeneration of the GMED were evident in the present study, which agrees with findings of previous reports [ 2 – 4 ]. Correlation of hip abductor strength with limping score of HHS, rather than hip pain or walking distance, indicated the importance of hip abductor muscle strength for normal gait in patients with unilateral hip OA.…”

“…Thus, dysfunction of the GMED is responsible for unstable hip and postural imbalance of the pelvis during ambulation. A reduction in the volume of the GMED in patients with hip osteoarthritis (OA) is a major reason for limping gait [ 2 – 4 ]. Therefore, quantification of the GMED can provide vital information for obtaining normal gait in patients with hip OA.…”

BackgroundThe gluteus medius (GMED) affects hip function as an abductor. We evaluated muscle volume and degeneration of the GMED by using CT-based analysis and assessed factors that affect hip abductor strength in patients with unilateral hip osteoarthritis (OA).MethodsWe examined clinical and imaging findings associated with hip abductor strength in consecutive 50 patients with unilateral hip OA. Hip abductor muscle strength and Harris hip score (HHS) were assessed. Leg length discrepancy (LLD) and femoral offset were assessed using X-ray; CT assessment was employed for volumetric and qualitative GMED analysis. Volumetric analysis involved measurement of cross sectional area (CSA) and three-dimensional (3D) muscle volume. CT density was measured for the qualitative assessment of GMED degeneration with or without adjustment using a bone mineral reference phantom.ResultsHip abductor muscle strength on the affected side was significantly lower than that on the contralateral healthy side and positively correlated with overall score and score for limping of gait of HHS, demonstrating the importance of hip abductor strength for normal hip function. A significant correlation was found between CSA and 3D muscle volume, unadjusted CT density and adjusted CT density, and hip abductor strength and these CT measurements. Multiple linear regression analysis demonstrated that 3D muscle volume, adjusted CT density, and LLD are independent factors affecting hip abduction.Conclusions3D measurement of muscle volume and adjusted CT density more accurately reflect quantity and the GMED quality than do conventional assessments. Increase in muscle volume, recovery of muscle degeneration, and correction of LLD are important for improving limping in patients with hip OA.

“…This may correlate with BMI through higher muscle mass in men. This is consistent with another study showing equal relative hip muscle distribution in women and men but higher absolute muscle volumes and more muscle relative to BMI in men compared with women [27]. When controlling for other variables like sex and BMI, this study showed no overall differences in muscle damage when using a short versus standard length stem.…”

Study Design Secondary analysis, cross-sectional study Background Chronic hip joint pain (CHJP) can lead to limitations in activity participation, but the musculoskeletal factors associated with the condition are relatively unknown. Understanding the factors associated with CHJP may help develop rehabilitation strategies to improve quality of life of individuals with long-term hip pain. Objectives To compare measures of hip abductor muscle volume and hip abductor muscle strength between women with CHJP and asymptomatic controls. Methods Thirty women, 15 with CHJP and 15 matched asymptomatic controls (18–40 years of age), participated in this study. Magnetic resonance imaging was used to determine the volume of the primary hip abductor muscles, consisting of gluteus medius (GMed), gluteus minimus (GMin), a small portion of gluteus maximus (GMax), and tensor fascia latae (TFL), within a defined region of interest. Break tests were performed using a handheld dynamometer to assess hip abductor strength. During the strength test, the participant was positioned in sidelying with the involved hip in 15° abduction. Independent-sample t tests were used to compare muscle volume and strength values between those with CHJP and asymptomatic controls. Results Compared to asymptomatic controls, women with CHJP demonstrated significantly increased gluteal muscle volume (228±40cm3 versus 199±29cm3; p=.032), but decreased hip abductor strength (74.6±16.8Nm versus 93.6±20.2Nm; p=.009). There were no significant differences in TFL muscle volume between the two groups (p=.640). Conclusions Women with CHJP appear to have larger gluteal muscles, but decreased hip abductor strength compared to asymptomatic controls.
