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.

| Measure | Description | Time Frame |
|---|---|---|
| Harris hip score | HHS index score of 0 indicates the worst possible function of the hip and a value of 100 indicates full function. | 17 years |
| Measure | Description | Time Frame |
|---|---|---|
| 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.
