Bipolar Hemiarthroplasty Vs Total Hip Replacement | …

Bipolar hip hemiarthroplasty is used in the management of fractures of the proximal femur. The dual articulation is cited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rates and is easier to convert to a total hip arthroplasty (THA) should the need arise. However, these claims are debatable. Our study examines the rate of conversion of the bipolar hemiarthroplasty to THA and the justification for using it on the basis of future conversion to THA.

Both clinical and radiographic follow-up ranged from 1 month to 6 years (median, 1 month) reflecting our unit policy of not routinely following up hip fracture patients. With a minimum time from surgery of 1 year, 4 patients out of 164 had undergone revision of their bipolar prosthesis into THA. One patient underwent revision to a THA due to groin pain after 2 years, with the remaining patients undergoing revision for infection, dislocation and fracture (one of each). Two patients had removal of their implants due to persistent infection. Both patients were not medically fit for further revision.

The published literature refutes the proposed bipolar benefits of less erosion and less dislocation, and demonstrates equal functional outcomes to unipolar hemiarthroplasty.- Conversely, dealing with complications arising from bipolar arthroplasty can be more difficult. Dislocation of the bipolar hip implant for example, is more likely to require open reduction or to undergo dissociation of the implant.

"Bottle-Opener" Effect in Bipolar Hip Prostheses Dislocations

Between 2002 and 2007, fifty elderly patients with displaced femoral neck fractures were treated with hip replacement at Emergency Hospital, Mansoura University. Patients were randomly selected, 25 patients had either cemented or cementless bipolar prosthesis, and another 25 patients had either cemented or cementless fixed-head prosthesis. There were 34 women and 16 men with an average age of 63.5 years (range between 55 and 72 years). All patients were followed up both clinically and radiologically for an average 4.4 years (range between 2 and 6 years). At the final follow-up, the average Harris hip score among the bipolar group was 92 points (range between 72 and 97 points), while the fixed-head group was 84 points (range between 65 and 95 points). Radiologically, joint space narrowing more than 2 mm was found in only 8% (2 patients) among the bipolar group, and in 28% (7 patients) of the fixed-head group. Through the follow-up period, total hip replacement was needed in two cases of the bipolar group and seven cases of the fixed-head group. Bipolar hemiarthroplasty offered a better range of movement with less pain and more stability than the fixed-head hemiarthroplasty in elderly patients with displaced femoral neck fractures.

If only one part of the joint is damaged or diseased, a partial hip replacement may be recommended. In most instances, the acetabulum is left intact and the head of the femur is replaced, using components similar to those used in a total hip replacement. The most common form of partial hip replacement is called a bipolar prosthesis.
