A Modified Step-Cut (Reverse V) Osteotomy to Treat Posttraumatic Cubitus Varus Deformity

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Surgical techniques

Background:

• Posttraumatic cubitus varus deformity is a common complication in children.
• Accurate correction is crucial for restoring elbow function and preventing long-term issues.
• Current methods aim for stable and precise correction, especially in younger patients.

Purpose of the Study:

• To evaluate the efficacy of a modified step-cut (reverse V) osteotomy for correcting posttraumatic cubitus varus deformity in children.
• To determine if focusing correction solely on the coronal plane is sufficient for precise and stable outcomes in this age group.

Main Methods:

• A modified step-cut (reverse V) osteotomy was performed on pediatric patients.
• The procedure involved exposing the distal humerus, performing a triangular osteotomy, and reducing the deformity.
• Fixation was achieved with Kirschner wires, followed by splint immobilization and early active motion.

Main Results:

• The study included eight patients with an average age of 6.8 years.
• The modified step-cut osteotomy allowed for precise and stable correction of cubitus varus deformity.
• Focusing on coronal plane correction was sufficient for achieving desired outcomes in this cohort.

Conclusions:

• A modified step-cut osteotomy is an effective method for correcting posttraumatic cubitus varus deformity in children under ten.
• Coronal plane correction alone is adequate for achieving precise and stable results in this patient population.
• This technique offers a reliable surgical option for pediatric elbow deformities.
