Undisplaced Femoral Neck Fractures

Completed

• Conditions: Hip Fractures; Arthroplasty Complications; Femoral Neck Fractures; Undisplaced Fracture; Internal Fixation; Complications
• Interventions: Device: Internal fixation or hip arthroplasty

• Registration Number: NCT03392285
• Lead Sponsor: Sundsvall Hospital

Brief Summary

Purpose The purpose of this study is to compare the clinical outcome and the rate of reoperations in a cohort of patients with undisplaced femoral neck fractures treated with internal fixation and patients with displaced femoral neck fractures treated with hip arthroplasty.

Methods In a consecutive series of patients we compared the results of internal fixation for undisplaced femoral neck fractures with those of hip arthroplasty for displaced fractures (control group) of elderly patients. Risk of reoperation and patient reported hip function assessed with Harris hip score and WOMAC were used as outcome measurements.
