UNLABELLED: The incidence rate of periprosthetic fractures has increased in the past decade. Osteolysis, age and preoperative function are factors that influence morbidity. Treatment options include conservative and surgical treatment.
OBJECTIVES: To conduct a study analyzing the functional results of the surgical treatment of periprosthetic hip fractures at the ABC Medical Center considering preoperative and postoperative variables.
MATERIAL AND METHODS: Cross-sectional retrospective study of patients with a diagnosis of periprosthetic hip fracture between January 2000 and December 2011, classified using the Vancouver system. The Oxford Hip Score was used pre- and postoperatively as a functional measure. The variables to evaluate included age, sex, surgical technique, and the time elapsed between primary surgery and the periprosthetic fracture.
RESULTS: Twenty-five patients were analyzed; frequency was 3.3 cases per year. 80% of periprosthetic fractures were postoperative; 72% were total hip arthroplasties. The time elapsed between primary surgery and the traumatic event was 2 to 4 years (68%), with a mean of 4.5 years for hemiarthroplasties and 3.9 years for total arthroplasties. Patients who according to the Oxford Hip Score had good function maintained their results; 75% of those with moderate function maintained their score. Patients with poor function improved.
CONCLUSIONS: At the ABC Medical Center, the outcomes of the treatment of periprosthetic hip fractures are considered as good according to the Oxford Hip Score.
