Background: Treatment of periprosthetic femoral fractures (PPFF) is difficult. Careful pre-operative planning and meticulous intra-operative technique during hip arthroplasty is the most important aspect in the preventio n of periprosthetic fractures. Objective:The aim of the present study was to evaluate the results of surgical treatment of Vancouver C periprosthetic femoral fractures. Methods: The study included 18 patients presented to orthopedic department at Zagazig University Hospitals. ORIF with plate osteosynthesis was used in patients with type C PPF fractures. Time of follow up from six months to one year. Results: Seven patients responded good satisfaction (38.9%), five responded fair satisfaction (27.8%), three patients had excellent feedback (16.7%), and three patients had poor experience (16.7%). The final results were affected by the time lapse before the occurrence of fracture and the time lapse before union and wasn't affected by the age, sex or the timing of occurrence of the fracture. Functional outcome after healing of the fracture was less than the preinjury stage.
