Summary
Minimally invasive periacetabular osteotomy (PAO) using endoscopy is feasible in cadavers. This technique may reduce surgical trauma for hip dysplasia reconstruction in young adults.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Hip Reconstruction
Background:
- Periacetabular osteotomy (PAO) is a standard surgical procedure for hip dysplasia.
- Traditional PAO requires large incisions, leading to significant surgical trauma and longer recovery times.
Purpose of the Study:
- To evaluate the feasibility of performing PAO using a mini-incision under direct endoscopic control.
- To assess the safety and efficacy of this novel minimally invasive approach in cadaveric specimens.
Main Methods:
- Five fresh-frozen cadaver pelves were used for the study.
- Specialized curved guides and osteotomes were developed for the endoscopic osteotomy.
- The procedure was performed under direct endoscopic and image intensifier guidance, followed by fixation with cannulated screws.
Main Results:
- A complete periacetabular osteotomy was successfully performed in all five cadavers using the mini-incision endoscopic technique.
- No damage to vital neurovascular structures or intra-articular fractures were observed during post-procedure dissection.
- The osteotomy was effectively stabilized using two cannulated screws.
Conclusions:
- Periacetabular osteotomy can potentially be performed via a mini-incision with direct endoscopic visualization.
- This preliminary cadaveric study suggests that minimally invasive PAO may be a viable option for experienced surgeons to explore in clinical trials.
