Factors influencing the incidence of reoperation after femoral neck fractures.

This investigation compares two groups of patients with fractures of the femoral neck: 22 required a further operation and 72 did not. Special attention was paid to osteoporosis, the displacement of the fracture, viability of the femoral head, operative impaction and osteosynthesis with a Thornton nail or three Scand hip pins. There was a significant (p less than 0.01) difference between the two groups with regard to osteoporosis, fracture displacement and viability of the femoral head. Scand hip pins, as compared to Thornton nails, showed a tendency (p less than 0.1) to need a smaller number of reoperations. Operative impaction compared with no impaction showed no difference.
