Summary
This study standardized the scarf osteotomy procedure for hallux valgus correction. It provides a framework for surgical training, simulation, and assessment to improve consistency and reduce complications.
Area of Science:
- Orthopedic Surgery
- Surgical Technique Standardization
Background:
- The scarf osteotomy is a common procedure for correcting hallux valgus (bunion).
- Variability in surgical technique execution can lead to inconsistent outcomes and potential complications.
Purpose of the Study:
- To establish a standardized sequence of key procedural steps for the scarf osteotomy.
- To guide surgical training, simulation, and assessment in hallux valgus correction.
Main Methods:
- A three-round Delphi consensus process was employed.
- An expert panel of foot and ankle surgeons participated in the consensus process.
Main Results:
- Statements achieving predefined consensus thresholds were identified.
- A standardized framework for the scarf osteotomy procedure was developed.
Conclusions:
- The study provides a framework for standardizing the scarf osteotomy procedure.
- This standardization can inform training curricula, simulation design, and assessment criteria.
- The findings aim to improve surgical consistency and reduce complications related to technical variability.
