Background and purposeProspective studies on patient related outcome in patients <70years with a femoral neck fracture (FNF) are few. We aimed to investigate functional outcome and health-related quality of life (HRQoL) in 20–69years old patients with a FNF treated with internal fixation.Patients and methods182 patients, 20–69years with a FNF treated with internal fixation were prospectively included in a multicenter study. Follow up included radiographic and clinical examination at 4, 12 and 24 months. Collected data were hip function using Harris Hip Score (HHS), HRQoL (EQ-5D and SF-36), fracture healing and re-operations.ResultsAt 24 months, HHS was good or excellent in 73% of the patients with displaced fractures and 85% of the patients with non-displaced fracture (p=0.15). Of the patients with displaced fracture (n=120), 23% had a non-union (NU) and 15% had an avascular necrosis (AVN) with a 28% re-operation rate. None of the patients with non-displaced fracture (n=50) had an NU, 12% had a radiographic AVN and 8% needed a re-operation. The mean EQ-5Dindex in patients with displaced fracture decreased from 0.81 to 0.59 at 4 months, 0.63 at 12 months and 0.65 at 24 months (p<0.001). The corresponding values for patients with non-displaced fracture were 0.88, 0.69, 0.75 and 0.74 respectively (p<0.001). The mean SF-total score in patients with displaced fracture decreased from 76 to 55 at 4 months, 63 at 12 months and 65 at 24 months (p<0.001). The corresponding values for patients with non-displaced fracture were 80, 67, 74 and 76 respectively (p<0.001).InterpretationTwo thirds of the patients with displaced femoral neck fracture healed after one operation and three quarters reported good or excellent functional outcome at 24 months. However, they did not regain their pre-fracture level of HRQoL.
