Traumatic upper arm defect treated with latissimus dorsi muscle transposition

Area of Science:

• Orthopedic surgery
• Pediatric reconstructive surgery
• Microsurgery

Background:

• Acute upper extremity injuries in children can lead to significant functional deficits and cosmetic concerns.
• Restoring both form and function is crucial for optimal recovery and quality of life in pediatric patients.
• The latissimus dorsi muscle is a large, versatile flap often used in reconstructive procedures.

Observation:

• A child presented with an acutely injured upper extremity requiring reconstructive surgery.
• The latissimus dorsi muscle transfer was performed to address contour and functional deficits.
• Exposed vital structures were protected by the transferred muscle, and a split-thickness skin graft was used for coverage.

Findings:

• Latissimus dorsi muscle transfer effectively restored contour and function to the injured upper extremity.
• The procedure provided essential protection for underlying neurovascular structures.
• Adequate elbow flexion was achieved without necessitating transposition of the latissimus dorsi insertion.

Implications:

• Latissimus dorsi muscle transfer is a viable and effective option for pediatric upper extremity reconstruction.
• This technique offers a reliable method for protecting vital structures during reconstruction.
• The findings suggest that complex flap modifications may not always be required for functional restoration.
