Abstract:

A prospective study of 110 Corail® uncemented hemiarthroplasties performed for fresh femoral neck fractures in 110 patients was carried out. The patients were followed during 10 years, unless they died before. Mean patient age was 84 (63-99) years; 75% were women and 25% had mental impairment. Implantation was uneventful in all patients except 7 (6 calcar cracks and 1 major trochanter fracture). Full-weight-bearing was allowed in almost every uncomplicated case, with only one 9-mm subsidence explained by the use of an undersized implant. A comprehensive radiographic analysis was undertaken in 44 hemiarthroplasties with a minimal implantation time of five years. A constant pattern of radiologic changes was identified and described. No loosening was noted; however, 7 radiolucent lines were seen in Zone 1 and 3 in Zone VII. Results of this prospective survey indicated that the HA-coated Corail prosthesis produces favorable functional and radiological outcomes for these elderly and frail patients.
