A Novel Surgical Indication for Scheuermann's Kyphosis

Area of Science:

• Orthopedic Surgery
• Spinal Deformity Correction
• Pediatric Orthopedics

Background:

• Scheuermann kyphosis often requires surgical correction for thoracic curves exceeding 70 degrees to achieve proper sagittal alignment.
• Patients with maximal compensatory lumbar hyperlordosis face risks of accelerated degeneration, necessitating careful pre-operative assessment.

Observation:

• Assessing lumbar lordosis in standing neutral and supine extension radiographs identifies patients at risk.
• Minimal additional lordosis in extension, spinous process abutment, or greater standing lordosis suggests maximal compensation.

Findings:

• A case report details an adolescent with Scheuermann kyphosis at their limit of hyperlordosis compensation.
• The patient underwent successful posterior spinal fusion and Ponte Smith-Petersen osteotomies with no complications.

Implications:

• This case highlights the importance of evaluating compensatory mechanisms in Scheuermann kyphosis surgical planning.
• Early identification and appropriate surgical techniques can lead to successful outcomes and return to activity.
