“…Our results disagree with the randomized prospective study of Van Thiel et al [21] and Calder et al [18] , who did not find any differences between the Moore unipolar and bipolar prostheses concerning acetabular erosion. Our results are consistent with Yamagata et al [22] and D'Arcy and Devas [23] who found more erosion with unipolar prosthesis, and Wetherell and Hinves [14] who reported a rate of erosion of 5.6% with the bipolar implant compared with 11% for the cemented Thompson prosthesis.…”

Between 2002 and 2007, fifty elderly patients with displaced femoral neck fractures were treated with hip replacement at Emergency Hospital, wasity hospital .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 radio-logically 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.

“…In addition, this finding was not reflected in the daily living activities (Harris hip and Barthel scores). Similar clinical studies have shown that radiological erosion does not lead to clinical complaints (9,10). Although significant acetabular erosion with unipolar prostheses has been reported (10), it was caused by the younger age and higher daily living activity of the affected patients (6,9).…”

“…Some authors advocate the unipolar prosthesis, whereas others prefer the bipolar prosthesis (5)(6)(7)(8)(9)(10)(11)(12)(13). The theoretical advantage of the bipolar prosthesis is the motion at its inner bearing in addition to the prosthesis-acetabulum interface (14).…”

Background: The choice of prosthesis in hemiarthroplasty is controversial for geriatric patients after femoral neck fracture. We hypothesised that selection criteria for unipolar or bipolar prostheses could be constructed based on factors affecting mortality. Aims:The aims of this retrospective study were: (1) to determine the factors affecting mortality of femoral neck fracture patients ≥65 years of age; (2) to compare patient mortality rates, radiological findings, and functional outcomes according to prosthesis type (unipolar or bipolar); and (3) to evaluate the persistence of inner bearing mobility of bipolar prostheses.Study Design: Retrospective comparative study. Methods:In total, 144 patients operated for hemiarthroplasty and aged ≥65 were included. We classified the patients into either unipolar or bipolar prosthesis groups. To reveal factors that affected mortality, age, sex, delay in surgery, and American Society of Anesthesiologists score were obtained from folders. Barthel Daily Living, Harris hip, and acetabular erosion scores were calculated and bipolar head movement was analysed for live patients.Results: One-year mortality was 31.94%. Age ≥75 (p=0.029), male sex (p=0.048), and delay in surgery ≥6 (p=0.004) were the patient characteristics that were related to increased mortality. There were no significant differences in sex, age, American Society of Anesthesiologists score, delay in surgery, mortality, or Barthel, Harris, acetabulum scores between the two groups. Twenty patients from each group were admitted for last follow-up. Bipolar head movement was preserved for 33.3% of patients. They were inactive patients with low Barthel and Harris scores. Conclusion:Although bipolar head movement was preserved in inactive patients, we suppose that this conferred no advantage to these patients, who could hardly walk. In this study, male patients, those aged ≥75 years, and those operated at ≥6 days had an increased risk of mortality. Also, although not significant in multivariate analysis, high American Society of Anesthesiologists score (≥3) was related to increased mortality. Considering that one of three patients died during the first postoperative year, we think that these patients should be operated as soon as possible, and expensive bipolar prostheses must be used selectively in regard to patient characteristics.

“…Numerous different implants and designs are used, but no definite conclusions have been made regarding what type of hemiarthroplasty is most favorable Gurusamy 2004, 2005). Acetabular cartilage degenerates more rapidly in response to articulation with a metallic hemiarthroplasty component (Dalldorf et al 1995), but several studies have shown excellent long-term results of bipolar hemiarthroplasties (Wetherell and Hinves 1990, Eiskjaer and Ostgard 1993, Haidukewych et al 2002. Conversion of a well-fixed hemiarthroplasty with failure on the acetabular side has been reported to be a simple procedure using a standard acetabular cup; the femoral stem may be left in situ (Sierra and Cabanela 2002).…”
