“…It has been reported that fatty infiltration into muscle increases with age 29,40 . Fatty infiltrate can be due to disuse in these muscles 41 , denervation of muscles 42 and as a result of certain metabolic disorders 43 .…”

“…GMed and GMin atrophy has been identified in normal ageing, with atrophy present in approximately one third of people aged between 60 and 69 years and one half of the population over 70 years 29 . The progression of atrophy in advanced OA has been identified previously in unilateral OA 11 although no significant differences were identified in a meta-analysis when comparing either an OA and control group or affected and unaffected sides 9 .…”

“…6,10 There may also be a specific sequence of atrophy between the segments of the GMin, with the anterior segments seen to atrophy before the posterior segments in people with endstage OA, 11 after total hip replacement (THR) 12 and in normal aging. 13 Recent studies 14,15 have identified altered GMed muscle electromyography (EMG) in people with severe OA. However, the use of a surface electrode on GMed in these studies precludes the evaluation of individual segments of GMed and brings into question the accuracy of muscle activity recordings since EMG signal contamination from surrounding muscles is probable.…”

The gluteal muscles act as stabilizers of the hip joint and are important for the maintenance of hip function. Atrophy and weakness of the gluteal muscles have been identified in people with hip OA, but it is not known whether these muscles also exhibit altered activity patterns. The aim of this study was to compare gluteal muscle activity in people with hip OA and healthy older adults. Fine-wire intramuscular electrodes were inserted into the three segments of gluteus medius (GMed) and two segments of gluteus minimus (GMin) in 20 participants with unilateral hip OA and 20 age-and gender-matched controls. Electromyographic activity of these muscle segments was examined during walking along a 10 m walkway. Peak amplitude, average amplitude, and time to peak were compared between groups during the stance phase of the gait cycle. During early stance, the OA group demonstrated a higher burst of activity in posterior GMin (P = 0.02) and trends toward a higher peak in anterior GMin. Both groups displayed peak activity in anterior GMin in the early stance phase in contrast to previous reports in young adults. This early burst of muscle activity was more pronounced with increasing severity of OA. No differences were identified in GMed activity. While altered GMin activity is associated with aging, these changes were more pronounced in participants with hip OA. To reduce disability associated with hip OA, future rehabilitation programs should consider targeted gait strategies and exercises for GMin.

“…In an older individual, disorders of the GMIN tendon encompass a spectrum of tendon abnormalities ranging from chronic degenerative tendinosis to partialthickness tears and, in some cases, eventually fullthickness tears. 28 In patients with GTPS, this process typically, but not exclusively, occurs in conjunction with AB GMED pathology. Patients will often present with greater trochanteric pain that also involves the anterolateral hip region.…”

Gluteus minimus disorders are a potential source of greater trochanteric or anterior hip pain. Disorders of the gluteus minimus tendon most commonly occur in conjunction with gluteus medius tendon abnormalities but can also occur in isolation. Understanding the sonoanatomy of the gluteus minimus muscle‐tendon unit is a prerequisite for recognizing and characterizing gluteus minimus tendon disorders, which, in turn, guides treatment for patients with greater trochanteric or anterior hip pain syndromes.
