Thoracic and Lumbar Spine Dissection for Pediatric Deformity

Area of Science:

• Orthopaedic Surgery
• Neurosurgery
• Spinal Anatomy

Background:

• Posterior approach is standard for idiopathic scoliosis (IS).
• Iatrogenic complications (durotomy, pneumothorax) can occur.
• Limited video resources exist for posterior element exposure.

Purpose of the Study:

• To provide a detailed, step-by-step guide to the posterior surgical approach for IS.
• To enhance trainee preparation for posterior spinal fusion (PSF).
• To highlight critical anatomical landmarks and potential pitfalls.

Main Methods:

• Review of the authors' preferred surgical technique for posterior spinal exposure.
• Focus on pearls and pitfalls of errant techniques.
• Inclusion of a sample pre-test for trainee knowledge assessment.

Main Results:

• Subperiosteal dissection is key for hemostasis.
• Thoracic spine dissection risks durotomy, pneumothorax, and nerve injury.
• Preserving facet joints and avoiding supraspinous ligament violation are crucial for outcomes.

Conclusions:

• A thorough understanding of posterior spinal anatomy is vital for safe and effective IS treatment.
• This technique article aims to improve surgical outcomes and reduce complications.
• Enhanced trainee education through detailed procedural guides is essential.
