The Hemiarthroplasty Procedure with Austin-Moore Prosthesis in the Treatment of Displaced Femoral Neck Fractures Technical Aspects and Their Role in the Functional Results

Abstract

Purpose. The assessment of the frequency of during surgery technical errors about the implantation of Austin-Moore prosthesis for the patients treated at our hospital. Review of the technical aspects for the implantation of Austin-Moore prosthesis. Patients and Methods. We retrospectively reviewed the medical records and radiographs of all our patients, treated with the Austin Moore prosthesis, problems that have arisen during the surgery, the initial problems, prosthetic failures etc. Results. 48% of patients had at least one intra-operatory error, 14% of cases had intra operatory fractures. Mistakes had significant correlation with the surgeons experience who have conducted the hemiarthroplasty with Austin Moore prosthesis. Conclusion. Austin Moore prosthesis is difficult to implant and requires skilled surgeons with good experience and good technique. When using this type of prosthesis in the fractures of the femoral neck the case should be selected very well. Keywords: hemiarthroplasty, prosthesis, Austin- Moore, fracture, femoral neck.
