EVANS, WEST, MINOR, DETACHMENT
The study was designed as a double-blinded randomized clinical trial, with blinding for patients and outcome assessors but not to the surgeons. Between December 2008 and January 2013, 37 patients were enrolled having sustained a stable pertrochanteric fracture with an intact greater trochanter and lateral femoral wall, regardless of detachment of the minor trochanter (Evans type I, II and IV). Patients were operated at two centers: Copenhagen University Hospital, Hvidovre, and Holstebro Regional Hospital, Hospital Unit West, Holstebro. Patients were randomly assigned to a lag screw with either a HA-coated screw thread or a NON-coated screw thread (Fig. CONSORT flow chart showing the inclusion/exclusion process until 6-month final follow-up
