A prospective randomized study comparing a new implant with three interlocked pins for internal fixation of femoral neck fractures (Hansson Pinloc System, Swemac Linköping, Sweden) versus 2 parallel pins with hooks (Hansson Pins, Swemac Linköping, Sweden).
Patients, who are to be treated with internal fixation due to a femoral neck fracture, will be randomized by the surgeon to Pinloc or Hansson Pins using an on-line randomization system. The patients will be followed up at open visits at 3 months and 1 year. At two years the patients will be contacted by phone and medical records studied in order to detect any fracture complications.
