The pelvic support osteotomy: indications and preoperative planning

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Hip reconstruction

Background:

• Neonatal septic arthritis can lead to severe hip joint destruction.
• This destruction often results in Trendelenburg gait and short limb gait in young patients.
• Pelvic support osteotomy is a surgical technique developed to address these complications.

Purpose of the Study:

• To provide a historical overview of the evolution of pelvic support osteotomy.
• To present an analysis of preoperative assessment for planning the procedure.
• To determine optimal placement and correction angles for the double level femoral osteotomy.

Main Methods:

• Review of historical modifications to the pelvic support osteotomy procedure.
• Analysis of preoperative assessment parameters for surgical planning.
• Defining specific criteria for the location and correction magnitude of each osteotomy level.

Main Results:

• The study outlines key considerations for the first osteotomy: optimal location and desired valgus/extension correction.
• It details the second osteotomy: optimal location and desired varus/derotation correction.
• Preoperative assessment is crucial for successful surgical planning and execution.

Conclusions:

• Pelvic support osteotomy is an effective procedure for correcting gait abnormalities secondary to hip destruction.
• Precise preoperative planning, including accurate assessment of osteotomy levels and correction angles, is essential for optimal outcomes.
• This approach aims to improve functional mobility in young patients affected by severe hip joint destruction.
