Surgical Correction of Thoracic and Thoracolumbar TB Kyphosis by Posterior Only Approach Using Rajasekaran's Kyphosis...

Area of Science:

• Spine Surgery
• Orthopedic Surgery
• Infectious Disease (Spinal Tuberculosis)

Background:

• Spinal tuberculosis (TB) can lead to significant kyphotic deformity.
• Treatment strategies for spinal TB kyphosis vary based on disease activity.
• A posterior-only surgical approach is evaluated for efficacy in correcting kyphosis.

Purpose of the Study:

• To analyze clinical and radiological outcomes of thoracic and thoracolumbar TB kyphosis correction.
• To compare outcomes between active and healed spinal TB kyphosis.
• To assess the utility of a posterior-only surgical approach using kyphosis classification.

Main Methods:

• Prospective analysis of retrospective data from 52 patients with spinal TB kyphosis (>30°).
• Patients categorized into Group A (Active TB) and Group B (Healed TB).
• Kyphotic deformity classified using Rajasekaran classification; posterior-only surgical techniques employed.

Main Results:

• Group A (Active TB, n=25) had mean pre-op kyphosis of 39.5°, reduced to 20.8° at 2-year follow-up.
• Group B (Healed TB, n=27) had mean pre-op kyphosis of 85°, reduced to 53.5° at 2-year follow-up.
• Different surgical techniques were required based on kyphosis type and disease activity.

Conclusions:

• Correction strategies for spinal TB kyphosis differ significantly between active and healed disease.
• A posterior-only surgical approach, guided by Rajasekaran's kyphosis classification, aids decision-making.
• This classification system helps tailor surgical plans for optimal outcomes in spinal TB kyphosis.
