Hemiartoplasty of the Hip Joint with a Bipolar Endoprosthesis for Fail Osteosynthesis of the Femoral Neck

Abstract

Introduction. Hip replacement in the last century was called the most successful operation in orthopedics. Replacement of the destroyed joint tissues with an implant allows to relieve a person from pain, restore motor activity and ensure a long-term improvement in the quality of life without disability. Endoprosthetics is indicated both for diseases of the hip joint, which according to the literature are affected by about 35 % of the adult population, and for fractures of the femoral neck. As a rule, the age of patients undergoing endoprosthetics is older than 60 years.The purpose of this publication is to demonstrate the successful experience of subtotal hip replacement with bipolar endoprosthesis in a patient with an ungrown fracture of the neck of the left hip in conditions of metalosteosynthesis with screws with migration of metal structures and violation of fracture consolidation.Materials and methods. Description of a clinical case and a brief analysis of the literature on this topic. The experience of subtotal endoprosthetics of the left hip joint with a bipolar endoprosthesis is presented. The effectiveness of treatment was evaluated based on the data of X-ray examination methods, as well as when assessing the function of the limb and the amplitude of movement in the hip joint.Results. As a result of hip replacement with a bipolar endoprosthesis, complete restoration of limb function and activity of the patient was achieved.Discussion. The choice of a bipolar endoprosthesis with acetabular roof plasty was due to the need to restore joint function and the desire to maintain a greater potential for revision arthroplasty of the patient, which is very likely given the age. Along with the use of augments and individual implants, the method showed a good result of treatment with less trauma.Conclusion. Based on the given clinical example, it can be concluded that both preoperative planning for femoral neck fractures with risk assessment and expanding the range of metal structures, including the least traumatic for bone tissue, is important, as well as the need to improve continuity in the treatment of patients and individualize the postoperative plan. management, socialization and activation of the patient
