270 · DOS Abstracts Prevalence of hypermobility and its impact on hip function 2-4 years after diagnosed with greater trochanteric pain syndrome Lisa C. U. Reimer, Julie S. Jacobsen, Inger Mechlenburg Orthopedics, Aarhus University Hospital; Physiotherapy, Faculty of Health Sciences, VIA University College; Clinical Medicine, Aarhus University Background: Greater Trochanteric Pain Syndrome (GTPS) is a common and dis- abling hip condition. Hypermobility has been suggested as a possible cause of GTPS. The purpose of this study was to report the prevalence of hypermobility and to investigate its impact on hip-related function and awareness in patients with GTPS. Purpose / Aim of Study: The primary aim of this study was to report preva- lence of GJH and investigate the impact of GJH on self-reported outcome in patients 2-4 years after initial diagnosis with GTPS. Materials and Methods: This cross-sectional study was based on a cohort of patients diagnosed with GTPS in the period 2013- 2015. Hypermobility was investigated with the Beighton score and defined by a cutoff score ≥5. Patients’ current hip function and awareness was collected with the questionnaires the Copenhagen Hip and Groin Outcome Score and the Forgotten Joint Score. Findings / Results: 612 patients with GTPS were identified based on the di- agnosis-system and out of these 145 (37%) were included. The prevalence of hypermobility within this cohort was estimated to be 11% (95% CI: 3;26) for males and 25% (95% CI:17;34) for females. No significant association was found between hypermobility and self-reported hip function and awareness. Conclusions: The prevalence of hypermobility in patients with GTPS was high but the prevalence of hypermobility did not influence hip function and aware- ness. The results were based on a very low response rate and should be inter- preted with this in mind. 211.
