Total Hip Arthroplasty Compared to Internal Fixation for Displaced Intracapsular Fractures of the Femoral Neck

Not Applicable

Completed

• Conditions: Femoral Neck Fracture
• Interventions: Procedure: Internal fixation; Procedure: Total hip arthroplasty

• Registration Number: NCT01344772
• Lead Sponsor: Danderyd Hospital

Brief Summary

The primary aim of this study was to determine the Harris hip score as an evaluation of hip function, in mentally competent elderly patients (\>65 years old) treated with either THR or IF, after contracting a displaced femoral neck fracture. The secondary aim was to compare the rate of reoperations and complications between the two groups.

Arm && Interventions

Group	Intervention	Description
Internal fixation	Internal fixation	Displaced femoral neck fracture treated with internal fixation using two parallel cannulated screws.
Total hip replacement	Total hip arthroplasty	Displaced femoral neck fracture treated with total hip replacement through a posterior approach.

Primary Outcome Measures

Name	Time	Method
Harris hip score	17 years	HHS index score of 0 indicates the worst possible function of the hip and a value of 100 indicates full function.

Secondary Outcome Measures

Name	Time	Method
Reoperations and complications	17 years	IF group: nonunion, osteonecrosis, deep infection or fracture in the vicinity of the screws. Protruding screws or extraction of the screws when the fracture was healed was not defined as a complication.; THR group: radiographic signs of loosening of the femoral- or acetabular component, dislocation, periprosthetic fracture or deep infection
