Inverted arcuate osteotomy and external fixation for adolescent tibia vara

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics

Background:

• Adolescent Blount's disease (tibia vara) is a developmental disorder affecting the proximal tibia.
• Accurate surgical correction is crucial for long-term outcomes and preventing secondary osteoarthritis.

Purpose of the Study:

• To describe and report the outcomes of a specific surgical technique for adolescent Blount's disease.
• To evaluate the efficacy and reliability of inverted arcuate osteotomy with external fixation.

Main Methods:

• Retrospective review of 15 patients undergoing inverted arcuate osteotomy.
• Combined surgical approach utilizing external fixation for stable support and adjustment.
• Assessment of surgical outcomes based on the Schoenecker criteria.

Main Results:

• 80% of patients achieved good or excellent results according to the Schoenecker criteria.
• Overcorrection was associated with poor outcomes, indicating the need for precise correction.
• The technique demonstrated effectiveness in correcting deformity across three planes.

Conclusions:

• Inverted arcuate osteotomy combined with external fixation is a reliable and effective surgical method.
• This technique offers a simple approach for managing adolescent tibia vara.
• Careful attention to avoiding overcorrection is essential for optimal patient results.
