The Incidence of Major Complications following Per-Acetabular Osteotomy (PAO)

Description

This video transcript features a presentation by Benjamin Rouse from Sheffield Children's Hospital Foundation Trust and the University of Sheffield. He discusses a study on the incidence of major complications following peri-acetabular osteotomy (PAO), a surgical intervention for acetabular dysplasia, a condition where the acetabulum (hip socket) is malformed or underdeveloped. Rouse explains the treatment of acetabular dysplasia, including conservative methods and surgical options like PAO, which aims to reposition the acetabulum to improve hip joint stability and delay the need for total hip arthroplasty.



Rouse then reviews existing literature on complication rates, noting that previous studies reported major complication rates ranging from 6% to 37%. His own study assesses complications in 243 hips across 220 patients, finding an overall complication rate of 38.8%, with a major complication rate of 7.4%. Common issues identified included acetabular migration and superior pubic ramus non-union. Despite the occurrence of complications, Rouse emphasizes that PAO remains a safe procedure.



The discussion addresses aspects such as patient demographics, surgical fixation methods, and limitations of the study, including the potential impact of body mass index (BMI) and age on complication rates.



As the audience poses questions, Rouse clarifies that findings may influence surgical practices regarding screw use and the preoperative counseling process for patients, informing them about the potential risks associated with their demographic profile. The presentation concludes with an emphasis on the need for further research, suggesting a longitudinal study to gather more comprehensive data.
