| Popis: | Surgery for hip fractures is one of the most common orthopaedic procedures and is set to increase over the coming decades.1,2) Although many surgical treatments are available for fractures of the proximal femur, most surgeons agree that older patients with a displaced intracapsular proximal femoral fracture should be treated by a hip arthroplasty.3) This can be either a total hip arthroplasty (THA) or a hemiarthroplasty.3) The ideal prosthesis is still debated and often depends upon surgeon, patient, and unit factors.2) Bipolar hip arthroplasty has been in use for the treatment of primary hip arthritis since 1974,4) but is most commonly now employed in the management of fractures of the proximal femur.5) The dual articulation is cited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rate and is "easy" to convert to a THA should the need arise. However, the published literature refutes the proposed bipolar benefits of less erosion and less dislocation, and demonstrates equal functional outcomes to unipolar hemiarthroplasty.6-10) Therefore, the only remaining reason to use bipolar arthroplasty (when the unipolar alternative is available) would be for planned conversion to THA, should the patient develop groin pain. The latter is the most common cause of revision of failed hemiarthroplasty to THA. It usually reflects either a progressive arthritis or a loosening of the stem.11,12) Universally, the cost of the bipolar arthroplasty implants are considerably greater than the cost of unipolar, therefore our aim was to examine the rate of conversion of bipolar hemiarthroplasty to THA and whether the additional expense of bipolar arthroplasty was justified on the basis of ease of future conversion to a THA because of groin pain. |
