Customized Triflange Hip Implant for Pelvic Discontinuity

Patient Overview: 

A 65-year-old female patient underwent primary hip replacement with standard cups on both hips. Postoperative CT scans revealed both cups had dislocated from the acetabulum cavity, indicating implant failure.  

Further assessment showed bilateral pelvic discontinuity, requiring a precise and customized surgical approach. 

 

 

Surgical Planning: 

Collaborating with Dr. Ramneek Mahajan, the team meticulously planned the surgery. Based on detailed CT scans, customized tri-flange hip implants were designed for left hip.  

Additionally, 3D FDM-printed models of both hips were created to identify deformities, ensuring thorough preoperative analysis and risk mitigation. 

3D-Printed, Patient-Specific Implants: 

The triflange hip implant was manufactured using metal 3D printing technology with medical-grade titanium Ti6Al4V, chosen for its strength and biocompatibility.  

The implant was tailored to fit the patient’s unique anatomy, providing enhanced stability and durability through its light weight and easy-to-bone integration nature. 

 

Post-op Outcome: 

The surgery on the left hip was successful, with the implant fitting seamlessly. Dr. Ramneek Mahajan expressed satisfaction with the outcome, emphasizing the crucial role of patient-specific design and detailed preoperative planning.

The patient showed great improvement in left hip stability and mobility, leading to a noticeable boost in overall quality of life. Thanks to the success of the left-side surgery, the upcoming procedure on the right side is expected to be smoother and more manageable.
