A clinical study and classification of posterior spinal tuberculosis

Area of Science:

• Orthopaedics
• Infectious Diseases
• Spinal Surgery

Background:

• Tuberculous involvement of the posterior spinal elements is an uncommon condition.
• Existing literature and orthopedic textbooks offer limited information on this specific spinal tuberculosis manifestation.
• This highlights a gap in understanding and managing posterior spinal tuberculosis.

Purpose of the Study:

• To analyze the clinical presentation, diagnostic investigations, and treatment outcomes of posterior spinal element tuberculosis.
• To introduce and validate a new four-point classification system for posterior spinal tuberculosis.
• To contribute to the limited body of knowledge regarding this rare spinal pathology.

Main Methods:

• A retrospective study of 27 cases of posterior spinal element tuberculosis over a 6-year period.
• Data collected from two centers: 21 cases from Central India and 6 from South Eastern Iran.
• Analysis of clinical findings, imaging results, treatment modalities, and patient outcomes.
• Development of a novel four-point classification based on lesion site, stage, associated lesions, and neurological deficit.

Main Results:

• The study details the varied clinical presentations and diagnostic challenges associated with posterior spinal tuberculosis.
• Treatment strategies employed included medical management and surgical interventions, with outcomes analyzed.
• A new four-point classification system was proposed to categorize the disease based on key pathological and clinical features.
• The classification aims to standardize reporting and potentially guide treatment decisions.

Conclusions:

• Posterior spinal element tuberculosis, though rare, requires careful clinical evaluation and appropriate management.
• The proposed four-point classification offers a structured approach to understanding and potentially treating this condition.
• Further research and larger studies are warranted to validate the classification and optimize treatment protocols for spinal tuberculosis.
