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

Danderyd Hospital100 enrolled

Overview

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.

Outcomes

Primary Outcomes

Harris hip score

HHS index score of 0 indicates the worst possible function of the hip and a value of 100 indicates full function.

Time frame: 17 years

Secondary Outcomes

Reoperations and complications

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

Time frame: 17 years
