Corrective Osteotomy for Hip Dysplasia: A PAO Case Guided by 3D Planning

A patient suffering from hip dysplasia recently underwent a peri-acetabular osteotomy (PAO). 

This condition, which can lead to pain and limited mobility, often requires complex surgical correction to restore proper alignment of the acetabulum and improve joint stability.

For this case, a detailed preoperative analysis was carried out, and a personalized surgical plan was developed. Using 3D imaging, the desired correction was carefully planned to ensure an optimal repositioning of the acetabulum. 

To support this plan in the operating room, a patient-specific cutting guide was created.

During the surgery, the guide was positioned on the bone and secured with seven K-wires, providing stability and precise orientation for the osteotomies. 

Step by step, the guide assisted the surgical team in performing the first 2 cuts accurately while maintaining control over the depths and trajectories defined during the planning phase. 

After the 2 other distal cuts were performed manually, the acetabulum was rotated and the k-Wires came into aligment in the desired position. 

The aligner guide was then inserted along the parallel k-Wires allowing for secure fixation of the bone fragments according to the initial plan.

The procedure was carried out smoothly, and the correction achieved was consistent with the objectives set during preoperative planning. 

Thanks to this approach, the patient benefited from a precise correction aimed at improving hip function and quality of life.
