Dual Mobility Cup Total Hip Arthroplasty (DMC-THA) in Neck of Femur Fractures in Elderly: A Prospective Study

Introduction: Neck of femur fracture persisted as a common hip fracture in the elderly. Various modes of treatment have been adopted with the aim of early mobilization and durability. However, conventional arthroplasty procedures have been associated with certain drawbacks which made the evolution of Dual Mobility Cup Total Hip Arthroplasty (DMC-THA) a potential selection. The present study was aimed to evaluate the functional and radiological outcomes of the use of DMC-THA in the management of neck of femur fractures in the elderly Indian population. Materials and Methods: A prospective study including 40 patients with fractured neck of femur in elderly treated with DMC-THA in a tertiary re hospital. The patients were evaluated in terms of functional and radiological outcomes during follow-up at 6 weeks, 3 months, 6months & 2 years. Results: Out of 40 patients, two patients were lost to follow-up and excluded from the study. The remaining 38 patients had shown good functional outcomes using the Harris hip score. Also, there was a significant improvement in the range of motion around the hip joint in the subsequent follow-ups. There were no reported complications like peri-prosthetic joint infection, dislocation, peri-prosthetic fracture. Conclusion: DMC-THA is an alternative to conventional THA in the surgical management of fractured neck of femur in elderly patients with the advantages of increased range of motion, less risk of dislocation, and improved postoperative rehabilitation.
