The Conversion Rate of Bipolar Hemiarthroplasty after a Hip Fracture to a Total Hip Arthroplasty
Sulaiman Alazzawi,Walter B Sprenger De Rover,James Brown,Ben Davis 대한정형외과학회 2012 Clinics in Orthopedic Surgery Vol.4 No.2
Background: Bipolar hip hemiarthroplasty is used in the management of fractures of the proximal femur. The dual articulation iscited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rates andis easier to convert to a total hip arthroplasty (THA) should the need arise. However, these claims are debatable. Our study examinesthe rate of conversion of the bipolar hemiarthroplasty to THA and the justifi cation for using it on the basis of future conversionto THA. Methods: All cases of bipolar hemiarthroplasty performed in our unit for hip fractures over a 9-year period (1999-2007) were reviewed. Medical notes and radiographs of all patients were reviewed, and all surviving patients that were contactable received atelephone follow-up. Results: Of all 164 patients reviewed with a minimum of 1 year from date of surgery, 4 patients had undergone a conversion oftheir bipolar prosthesis to THA. Three conversions were performed for infection, dislocation, and fracture. Only one (0.6%) conversionwas performed for groin pain. Conclusions: Our study show that bipolar hemiarthroplasties for hip fractures have a low conversion rate to THAs and this iscomparable to the published conversion rate of unipolar hemiarthroplasties.
