Abstract
PURPOSE: To assess outcomes for patients who sustained peri-implant fractures (PIFs). METHODS: Medical records of patients who sustained a PIF were reviewed for demographic, injury, outcome, and radiographic data. PIFs were classified using a reproducible system and stratified into cohorts based on fracture location. Clinical outcomes were evaluated for each cohort. RESULTS: Fifty-six patients with 61 PIFs with at least 6 months of follow-up were included. The mean age of the cohort was 60.4 ± 19.5 years. Twenty-two (36.1%) PIFs occurred in males, while 39 (63.9%) occurred in females. Fifty-two (85.2%) PIFs were sustained from a low-energy injury mechanism. PIFs were most often treated with plate/screw constructs (50.8%). Complications included: 6 (9.8%) nonunions, 5 of which were successfully treated to healing, 5 (8.2%) fracture related infections (FRI), and 1 (1.6%) hardware failure. Sixty (98.4%) PIFs ultimately demonstrated radiographic healing. CONCLUSION: PIFs are usually treated surgically and have a relatively high incidence of complications, with nonunion in femoral PIFs being the greatest. Despite this, the rate of ultimate healing is quite high.
