Mobility after intertrochanteric hip fracture fixation with either a sliding hip screw or a cephalomedullary nail: Sub group analysis of a randomised trial of 1000 patients

•Patients treated with a short cephomedullary nail have better mobility scores compared to those treated with a SHS.•Superior results relate to younger patients, based at home, cognitively intact and more independent pre-fracture.•ASA grade and patient sex did not influence patient mobility after surgical treatment for intertrochanteric hip fracture. The aim of this study was to determine if different patient groups have superior mobility regain following intertrochanteric hip fracture fixation with a cephomedullary nail compared to a sliding hip screw (SHS). The present study is a subgroup analysis of patients which were enrolled into a randomized controlled trial which randomized 1000 patients with an intertrochanteric hip fracture to fixation with either a short cephomedullary nail (Targon® PF or PFT) or a SHS. In the present study the two treatment groups were dicotomised on the basis of six variables determined at the time of admission; age (
