Interlocking wedge osteotomy for cubitus varus deformity

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Skeletal deformities

Background:

• Cubitus varus deformity is a common condition in children.
• It results in a decreased carrying angle and potential functional limitations.
• Previous treatments have limitations in addressing multiplanar deformities.

Purpose of the Study:

• To evaluate the efficacy of the interlocking wedge osteotomy for correcting cubitus varus.
• To assess the functional and radiographic outcomes of this surgical technique.
• To determine the safety and reliability of the interlocking wedge osteotomy.

Main Methods:

• Retrospective review of 20 pediatric patients with cubitus varus deformity.
• Treatment involved interlocking wedge osteotomy.
• Assessment included radiographic measurements and clinical evaluation of carrying angle, range of motion, and patient outcomes.

Main Results:

• Simultaneous correction of medial, posterior tilt, and internal rotation deformities was achieved.
• Mean carrying angle improved from 21.5° varus to 8.8° valgus.
• Elbow flexion increased, and hyperextension decreased, with a mean follow-up of 37 months.

Conclusions:

• The interlocking wedge osteotomy is an effective technique for correcting multiplanar cubitus varus deformities in children.
• It provides stable fixation and allows for three-dimensional correction.
• The procedure leads to significant improvements in elbow alignment and function.
