Greater Trochanteric Pain Syndrome: Epidemiology and Associated Factors

Abstract Segal NA, Felson DT, Torner JC, Zhu Y, Curtis JR, Niu J, Nevitt MC, for the Multicenter Osteoarthritis (MOST) Study Group. Greater trochanteric pain syndrome: epidemiology and associated features. Objectives To describe the prevalence of greater trochanteric pain syndrome (GTPS); to determine whether GTPS is associated with iliotibial band (ITB) tenderness, knee osteoarthritis (OA), body mass index (BMI), or low back pain (LBP); and to assess whether GTPS is associated with reduced hip internal rotation, physical activity, and mobility. Design Cross-sectional, population-based study. Setting Multicenter observational study. Participants Community-dwelling adults (N=3026) ages 50 to 79 years. Interventions Not applicable. Main Outcome Measures Greater trochanteric tenderness to palpation in subjects with complaints of hip pain and no signs of hip OA or generalized myofascial tenderness. Results The prevalence of unilateral and bilateral GTPS was 15.0% and 8.5% in women and 6.6% and 1.9% men. Odds ratio (OR) for women was 3.37 (95% confidence interval [CI], 2.67−4.25), but age and race were not significantly associated with GTPS. In a multivariate model, adjusting for age, sex, ITB tenderness, ipsilateral and contralateral knee OA, BMI, and LBP, ITB tenderness (OR=1.72; 95% CI, 1.34−2.19), knee OA ipsilaterally (OR=3.47; 95% CI, 2.72−4.42) and contralaterally (OR=1.74; 95% CI, 1.32−2.28), and LBP (OR=2.79; 95% CI, 2.22−3.50) were positively related to GTPS. In this complete model, BMI was not associated with GTPS (OR=1.10; 95% CI, 0.80−1.52 when comparing ≥ 30 with
