Intraoperative type 1 proximal femoral fractures: influence on the stability of hydroxyapatite-coated femoral components.
We reviewed a series of 120 uncemented total hip replacements using the Omniflex stem with hydroxyapatite coating. Twenty minor intraoperative proximal fractures occurred. All fractures were treated with cerclage wiring after removal of the stem. Radiographic and clinical results of these 20 patients were compared with the remaining 100 implants in which this complication did not occur. In 20% of the cases of both groups, a migration of less than 2 mm was observed. No differences were detected in Harris Hip Scores, subsidence of the stem, and radiographic behavior. We concluded that a properly stabilized proximal femoral fracture above the lesser trochanter did not influence the clinical and radiographic results at more than 3 years follow-up.
