Patients with operative gluteus medius tears often present with a concomitant history of lumbar pathology

Studies have indicated a correlation between patients presenting with decreased gluteus medius function and a history of lumbar pathology (LP). However, literature investigating the relationship between the prevalence of lumbar pathology in patients with gluteus medius tears is lacking. The purpose of this study is to determine if patients undergoing repair for gluteus medius tears have concomitant lumbar pathology.

Patients aged 18-80 who underwent endoscopic gluteus medius repair by one fellowship-trained surgeon between May 2016 and May 2020 for peritrochanteric pain/tenderness, abductor weakness, and MRI findings consistent with a gluteus medius tear were identified. Pre-operative and post-operative data were gathered using the Visual Acuity Scale (VAS), and post-operative data was gathered using the Abbreviated International Hip Outcome Tool (iHOT-12) and Hip Outcome Score - Activities of Daily Living (HOS-ADL). Outcomes were compared between patients with and without a history of lumbar pathology.

Of 23 hips, 19 (82.6%) presented with a prior history of lumbar pathology. Twenty (87.0%) patients identified were female. A total of 19 hips were included with completed PROM scores. Patients with lumbar pathology had similar pre and post-operative patient reported outcomes.

This study demonstrates a high incidence of lumbar pathology in patients presenting for operative gluteus medius tears, which may suggest an association between lumbar disease and the development of gluteus medius weakness and tears.
