The Kingston periacetabular osteotomy utilizing computer enhancement: a new technique

Area of Science:

• Orthopedic Surgery
• Computer-Assisted Surgery
• Hip Reconstruction

Background:

• Periacetabular osteotomy (PAO) is a critical procedure for hip preservation.
• Existing PAO techniques can be challenging to perform with consistent accuracy.
• Advancements in computer technology offer potential for improved surgical precision.

Purpose of the Study:

• To develop and evaluate a novel computer-enhanced periacetabular osteotomy (PAO) technique.
• To assess the safety, reliability, and accuracy of computer-guided PAO.
• To determine the potential of this technique to increase the adoption of PAO in hip reconstruction.

Main Methods:

• A modified posterior approach with trochanteric osteotomy was utilized.
• Computed tomography (CT) data generated a 3D surface model for surgical planning.
• An optically tracked system and custom software guided the three-dimensional osteotomies.
• Acetabular fragment repositioning and fixation with pelvic reconstruction plates were performed.

Main Results:

• The technique was successfully applied to eight patients.
• An average correction of 17 degrees in the center-edge angle was achieved.
• The computer and optical guidance system demonstrated accuracy in seven of eight cases.
• No intraoperative or postoperative complications were reported.

Conclusions:

• The developed computer-enhanced PAO technique allows for safe and predictable surgical outcomes.
• This technology has the potential to make periacetabular osteotomy a more widely utilized procedure.
• Computer-assisted navigation enhances precision in hip reconstruction surgery.
