The first twelve cases of computer assisted periacetabular osteotomy

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Surgical Navigation

Background:

• Dysplastic hips often require complex surgical interventions like the Bernese periacetabular osteotomy.
• Precise instrument guidance is crucial for successful outcomes in this procedure.
• Existing methods may lack the real-time feedback needed for optimal surgical control.

Purpose of the Study:

• To introduce and evaluate a novel image-guided freehand navigation system for Bernese periacetabular osteotomy.
• To assess the system's utility in preoperative planning and intraoperative control.
• To describe the features and clinical implementation of this surgical navigation technology.

Main Methods:

• Application of an image-guided freehand navigation system during Bernese periacetabular osteotomy.
• Utilization of computed tomography (CT) scan data for preoperative planning and surgical guidance.
• Development and integration of a sophisticated surgeon-machine interface.

Main Results:

• The navigation system has been successfully implemented in a clinical setting.
• The system has been utilized in 12 patient cases to date.
• Image data visualization supports preoperative planning and enhances surgical action control.

Conclusions:

• Image-guided navigation offers a novel approach to Bernese periacetabular osteotomy.
• The implemented system demonstrates feasibility and potential for improved surgical precision.
• Further clinical experience will refine the application of this technology in treating dysplastic hips.
