Abstract Background The separate design concepts of dual-mobility cups and triple-taper femoral stems were developed to improve survivorship following total hip replacement (THR) by reducing instability/dislocation and enabling enhanced fixation. Successful outcomes at over two decades have been reported with earlier-generation devices based on these concepts. The current study aimed to provide the first long-term results with a unique pairing of later-generation dual-mobility cup and triple-taper cementless femoral stem after a decade of use in patients undergoing THR. Methods In this retrospective analysis, records were reviewed for all subjects implanted with this dual-mobility cup/cementless femoral stem combination at three centers between 2002 and 2005. Any subject who had not already had follow-up visit beyond 10 years, was not previously revised, and still living were invited for a single follow-up visit consisting of Merle d’Aubgine Scores, the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index, and standard radiographs. Results There were 244 THRs available for analysis. At a mean follow-up of 11.9 years, the Kaplan-Meier survivorship (endpoint: revision for any reason) was 99.1% (95% CI, 97.6–99.7) for the stem and 95.9% (95% CI, 93.1–97.6) for the cup. Merle d’Aubigne Scores were significantly improved from baseline and WOMAC scores were in the satisfactory range at the final follow-up. Radiographic analysis revealed no cases of stem subsidence, no cases of bone hypertrophy, 1 (0.4%) case of bone atrophy, and 3 (1.2%) cases of osteolysis around the stem. No subjects had radiolucent lines greater than 1 mm in any femoral Gruen zone. Evidence of cup migration was seen in 1 (0.4%) subject and 1 (0.4%) subject had evidence of osteolysis that was seen in Gruen zones I, II, IV, and V. Conclusions This combination of a later-generation dual-mobility cup and cementless triple-taper stem was associated with excellent survivorship and satisfactory functional outcomes at over 10 years follow-up. Trial registration ClinicalTrials.gov, NCT02648152. Date of registration: January 6, 2016. Retrospectively registered.

Neck Of Femur Fracture

Introduction: Neck of femur fractures is the most common fractures in elderly people as they present with osteoporosis. There is a higher chance of proximal femur fracture in a schizophrenic patient as there is a loss of bone mineral density due to a drug-induced increase in the level of prolactin and immobility. Patients with Parkinson’s disease were at higher risk for the development of hip fractures due to gait disturbances and instability. Case Report: A 63-year-old male patient presented with complaints of the right arm pain, swelling, deformity of the right arm, and difficulty in extending the wrist for 3 days. The patient had a history of falls and trauma to the left arm at home. X-ray right arm showed distal one-third spiral humerus fracture for which intramedullary nailing was done. X-ray of the pelvis with both hips showed right neck of femur fracture with associated greater trochanter (GT) fracture. We managed with total hip replacement using a dual mobility cup and tension band wiring for GT fracture. Postoperatively, the patient has a good range of motion at the hip. The functional outcome is good as per Harris’s hip score. Conclusion: Neck femur fractures in elderly patients with associated comorbidities such as schizophrenia and parkinsonism are best managed with total hip replacement using a dual mobility cup. It avoids the risk of dislocation in high-risk patients and prevents secondary procedures. Careful clinical and radiological examination of the pelvis is very essential even in asymptomatic patients with a history of trauma to prevent delayed diagnosis of these types of fractures in patients with schizophrenia and parkinsonism.

SummaryAn eight-year-old male English Setter was referred for management of a dislocation of a cemented dual mobility canine total hip prosthesis that occurred four months after the initial surgery. Revision surgery showed that the dislocation was associated with fracture of the ultra-high molecular weight polyethylene liner. The dislocation was successfully reduced after replacing the liner. A dual mobility acetabular component is composed of a mobile polyethylene liner inside a metallic cemented cup. Chronic wear of the components of a canine dual mobility total hip replacement has not been described previously. The use of this type of implant is fairly recent and limited long term follow-up of the implanted cases may be the explanation. Acute rupture of a polyethylene liner has never been described in humans, the only case of rupture of a polyethylene liner occurred 10 years after implantation. The case presented here of rupture of the polyethylene liner of a dual mobility total hip replacement is a hitherto unreported failure mode in this model of acetabular cup in the dog.
