Jingchu Net (Hubei Daily Network) reported (correspondent Cheng Heyi, Cheng Yuhong) that recently, Vice President Pan Zhengqi of Xiangyang Sixth People’s Hospital (Xiangzhou District People’s Hospital) collaborated with Director Chen Wanjun of the Orthopedics Department, successfully completing the first 3D printing modeling-assisted complex hip joint revision surgery via a direct lateral approach in the supine position, with close cooperation from the anesthesia department. The successful implementation of this surgery provides a more precise and safer treatment plan for patients with complex hip joint diseases.
According to the patient, fifteen years ago, they underwent bilateral total hip replacement surgery due to avascular necrosis of the femoral head. Over time, the pain in the left thigh root has intensified. Diagnosis revealed loosening and upward migration of the hip joint prosthesis, along with mixed bone defects on the acetabular side. Such revision surgeries are challenging, prompting the orthopedic team at Xiangyang Sixth People’s Hospital to utilize 3D printing technology for the hip joint revision.

Before the surgery, Pan Zhengqi and Chen Wanjun utilized 3D printing modeling technology to conduct high-precision CT scans of the patient’s hip joint, obtaining detailed skeletal data. They then performed three-dimensional reconstruction using specialized software, creating a physical model that accurately represented the patient’s hip joint lesion at a 1:1 scale, clearly displaying the extent of the acetabular bone defect, the position of the prosthesis, and the distribution of surrounding blood vessels and nerves, while simulating various surgical plans.
After thorough preoperative preparation, the surgical team performed a complex artificial hip joint revision surgery. With the cooperation of the anesthesia department, they adopted a supine position, harvested structural bone grafts from the same side iliac crest, and for the first time used the direct lateral Hardinge approach to support the acetabular bone defect site with a wedge and mixed allograft bone particles for the joint revision. The surgical process was smooth, and postoperatively, the patient’s acetabular rotational center was restored with good initial stability of the cup.
The successful application of 3D printing modeling-assisted technology in hip joint revision surgery opens new pathways for orthopedic treatment. Xiangyang Sixth People’s Hospital established an orthopedic center in March this year, led by treatment group leaders with titles of associate chief physician or above. In the future, the hospital will continue to increase investment in medical technology innovation, actively introduce cutting-edge technology, and continuously improve the level of medical services to bring health and well-being to more patients.
