In early March, she underwent an artificial hip replacement in our bone and joint surgery department. “I didn’t know it was possible to replace the joint before, otherwise how else would I have endured the pain for more than 20 years.” Mrs. Wu is from Pei County, 20 years ago due to the pain in her right hip, causing her to walk very difficult for a long time, only with crutches can barely walk. In the past two years, Mrs. Wu’s left hip pain became more and more serious, and her activities were severely restricted, so she could not stand and walk for long distances. After many inquiries, Mrs. Wu came to our orthopaedic and joint surgery department with the help of her son, and was seen by Dr. Na Jian, the deputy chief physician. The patient was diagnosed with “aseptic necrosis of the left femoral head with severe dislocation” through pelvic radiographs, CT scan of both hips and other auxiliary examinations. The patient was diagnosed as “left femoral head aseptic necrosis with severe dislocation”. Dr. Na Jian, deputy chief physician, introduced that the patient’s fracture had led to complete necrosis of the left femoral head and dislocation, resulting in the formation of a pseudarthrosis, which could only be treated surgically. Due to the patient’s long onset, the surrounding soft tissue contracture, the shortening of the affected limb is obvious, the soft tissue adhesions are serious, the old fracture causes the proximal femur to heal malformed, and the normal anatomical joint is destroyed, many reasons make the surgery significantly more difficult. The patient’s basic condition determined that the surgery was difficult and risky, and that long-term exercise was needed to restore the joint function after successful surgery. The surgery was carried out as scheduled, and Dr. Na Jian, the deputy chief surgeon, and Dr. Wang Tao, the attending surgeon, performed the left total hip replacement under epidural anesthesia for Mrs. Wu in close cooperation with the Department of Anesthesiology. The surgeon used skillful techniques and careful thinking to ensure the precise installation of the joint, the restoration of the length of the affected limb, no damage to the muscles and sciatic nerve, and the adjustment of the anterior tilt angle to maintain the function of the joint and reduce the chance of acetabular dislocation. The operation went smoothly and the intraoperative bleeding was well controlled. After the operation, the patient’s vital signs were stable and her body gradually recovered, and both lower limbs were close to equal length, and she has been discharged from the hospital and resumed normal walking. In recent years, the Department of Bone and Joint Surgery of our hospital has performed artificial hip replacement for a number of patients like Mrs. Wu, all of whom have achieved good treatment results and relieved many patients with mobility problems.
