“…Dissociation is rare and has been reported in only a few case reports [4,7,8,13,16]. The reasons for disassociation after hemiarthroplasty have been reported as component selection and alignment, surgical technique, and patient factors [4,7,8,11,13,15,16]. Varley and Parker [25] reported that dissociations accounted for 12% of all dislocations in bipolar prostheses.…”

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?

“…A history of hip surgery, inadequate soft tissue tension, method of surgical approach, and preoperative [1,6,20,25,32]; it is known that patients with neuromuscular diseases have a greater incidence of postoperative dislocations after THA [9,25,31]. Once the dislocation has occurred, complications and morbidity related to difficulty in manual reduction, chances of open reduction, and replacement of prostheses increase [2,12,22,25,27]. Thus, prevention is more important than treatment.…”

“…Haidukewych et al [13] reported high component survivorship (95.1% at 5 years, 93.6% at 10 years, and 89.2% at 15 years) and a low dislocation rate (1.9%) after bipolar HA for displaced femoral neck fractures in elderly patients. However, high death rates (14%-47% [9,11,31]) and postoperative complication rates (32%-87% [11,31]) have been reported after surgically treating patients who had neuromuscular disease, particularly after the treatment of fractures about the hip [3,9,10,12]. Some studies suggest these patients have high rates of dislocation ranging from 10.6% to 45% [9,25,31], and decubitus ulcers ranging from 6% to 49% [9,25,31].…”

Background Patients with neuromuscular disease reportedly have a higher incidence of postoperative dislocation after bipolar hemiarthroplasty. Although the literature has focused on a high prevalence of preoperative neurologic conditions in patients who had dislocations after bipolar hemiarthroplasties, the relative incidence of dislocation in patients with neuromuscular disease and without is unclear. Questions/purposes We therefore (1) asked whether the incidence of postoperative dislocation after bipolar hemiarthroplasty was greater in patients with neuromuscular disease than for those without, and (2) whether function differed between the two groups, and (3) explored potential risk factors for dislocation in two groups.
