“…In the current study, another factor significantly associated with an increased risk of hip dislocation was discrepancy of offset; this could give rise to poor soft tissue tension and therefore contribute to the increased risk of dislocation. Other studies have found that lower offset was a risk factor for dislocation of unipolar hemiarthroplasty prostheses [14,18]. Mukka et al [17] reported that patients with single dislocations had no difference in postoperative femoral offset compared with age-and sex-matched control subjects, but there was a smaller femoral offset compared with offset in the patients with recurrent dislocations.…”

Background Hip dislocation after treatment of a femoral neck fracture with a hemiarthroplasty remains an important problem in the treatment of hip fractures, but the associations between patient factors and surgical factors, and how these factors contribute to dislocation in patients who have undergone bipolar hemiarthroplasty through an anterolateral approach for femoral neck fracture currently are only poorly characterized. Questions/purposes We evaluated patients with bipolar hemiarthroplasty dislocation after surgery for femoral neck fracture treated through an anterolateral approach and asked: (1) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dislocations? (2) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dissociations?

“…Dislocation of a bipolar hemiarthroplasty in a patient who received the implant to treat a hip fracture can be devastating [5,18]. The reported dislocation incidence of bipolar hemiarthroplasty ranges from 1.5% to 11% and may be associated with patient-and operation-related factors [1,17,22].…”

“…In our study, nine of the 15 had low activity because of dementia or hemiplegia. According to the result of the studies of Hur 5) , Iorio 10) , and Ninh 11) , the possibility of dislocation should not be overlooked. Especially in the patients with higher risk factors, extra awareness is required to prevent dislocation.…”

“…Hur 5) reported two cases of dislocation that happened in two incision total hip arthroplasty for femoral neck fracture in elderly patients and both of them had muscle weakness. Ninh 11) said central nerve disorders such as dementia, epilepsy and paralysis are risk factors for dislocation after hip arthroplasty in elderly people. In our study, nine of the 15 had low activity because of dementia or hemiplegia.…”

Introduction:We wanted to evaluate the efficacy of bipolar hemiarthroplasty using Berger's two-incision surgical technique for patients with muscular weakness around the hip joint and/or a high risk of dislocation. Materials and Methods:We performed bipolar hemiarthroplasty for 15 femoral neck fractures using Berger's twoincision technique between December 2005 and July 2007. The mean age of the patients was 75.2 years old. Four of them had difficulty in walking due to the sequalae after stroke and five have been treated for psychoneurologic disorders. We investigated the operation time, the length of the anterior and posterior incisions, the amount of bleeding, the time untill walking after the operation, the total hospital stay, the recovery to activities of daily living and the complications such as dislocation. Results:The mean operating time was 93 minutes. The average anterior and posterior skin incision length was 6.4 cm and 7.2 cm, respectively. The mean amount of bleeding was 420 cc at the time of surgery and 230 cc postoperatively through a drain. The patients started walking at a mean of 3.3 (1 to 5) days after the operation and the mean hospitalization was 24.3 days. Fourteen patients went back to their pre-injured activities of daily living, except one case with an intraoperative periprosthetic fracture. As for complications, two cases (13.3%) of femoral fracture were intraoperatively observed and one case of skin necrosis on the anterior incision site occurred. There were not any cases of dislocation or infection. Conclusion:Two-incision bipolar hemiarthroplasty had advantages for rehabilitation in elderly patients who have a high risk of dislocation, as well as in the patients with muscle weakness. But the operation took a long time and it had a high complication rate.

“…Decreasing femoral offset and limb-length shortening may reduce muscle tension, decreases the length of the lever arm, and may induce impingement between prosthesis and acetabulum, leading to dislocation [7][8][9]. Recent publications [5,8] also found a high association between a low center-edge (CE) angle and dislocation.…”
