Latent tb
Activation
Extrapulmonary tb (tertiary)

Treatment & management
Pharmacologic (Anti-TB Therapy - ATT):
Rhze 2months rh 4 months
Extended to 9-12 months for potts
Supportive Therapy:
Nutritional support (high protein, vitamins D & B6, calcium).
Pain management.
Bracing (short-term) to support unstable spine.
Physical therapy (isometrics → strength/posture rehab
Surgical Management (if indicated):
Neurological deficit, spinal instability, severe kyphosis (>60°), or failure of medical therapy.
Debridement, abscess drainage, spinal stabilization.
General Practitioner Role (3A Competency in Indonesia):
Diagnose and initiate treatment.
Refer to orthopedic and rehabilitation specialists for comprehensive care.
Prevention & education
Prevention
BCG Vaccination (infancy – reduces risk of severe TB forms).
Early treatment of pulmonary TB to prevent hematogenous spread.
Infection control measures:
Education
Recognize early TB signs: chronic back pain, weight loss, night sweats.
Complete TB treatment course to prevent resistance or recurrence.
Reduce stigma to encourage early care seeking.
Promote hygiene, nutrition, and adequate ventilation at home.
Prognosis & complications
a. Prognosis:
Favorable with early diagnosis and complete anti-TB treatment.
Most patients achieve microbiological cure and structural stabilization.
Delayed treatment → permanent deformities or neurologic deficits.
Children: risk of deformity progression due to growth after healing.
Neurological Deficits – due to spinal cord or nerve root compression.
Spinal Instability – due to vertebral destruction.
Kyphotic Deformity – gibbus formation, may impair function/cosmesis.
Systemic Spread of TB – potential for multifocal or miliary TB
Main diagnosis
Patients history
Tubercullin skin test (mantoux) 17mm
Gibbus deformity
Reason for consideration: Presents with fever, back pain, and possible abscess formation.
Reason for unlikelihood:
More acute onset than TB.
Patient lacks signs of sepsis or leukocytosis (normal WBC).
Spinal Epidural Abscess
Reason for consideration: Back pain, systemic signs of infection, tender spinal mass.
Reason for unlikelihood:
No neurological deficits.
No signs of acute infection like fluctuant mass or elevated leukocytes.
Traumatic
Vertebral Fracture
Reason for consideration: Can present with back pain and spinal deformity.
Reason for unlikelihood:
No history of trauma.
Chronic progression not typical of fractures.
Vertebral Dislocation
Reason for consideration: May cause deformity and back pain.
Reason for unlikelihood:
Patient lacks trauma history.
Neurological signs absent.
Neoplastic (Tumor)
Spinal Metastasis
Reason for consideration: Presents with chronic back pain, kyphosis, and systemic symptoms (weight loss, fatigue).
Reason for unlikelihood:
No known history of primary malignancy.
Patient is relatively young (30 years old) — uncommon age for metastasis.
Liposarcoma
Reason for consideration: Deep soft tissue mass possible in the back, especially retroperitoneally.
Reason for unlikelihood:
Usually painless until late stages.
Systemic symptoms like night sweats and fever are rare in liposarcoma
Autoimmune
Ankylosing Spondylitis
Reason for consideration: Presents with back stiffness, worsens at rest, HLA-B27 association.
Reason for unlikelihood:
Pain improves with rest (opposite of typical AS).
No mention of morning stiffness or sacroiliac involvement.
Rheumatoid Arthritis
Reason for consideration: Can involve the spine and cause deformities.
Reason for unlikelihood:
Typically affects cervical spine, not thoracic.
No joint pain, stiffness, or autoimmune markers mentioned.
Degenerative
Spondylolisthesis
Reason for consideration: Can cause chronic back pain and visible spinal lump.
Reason for unlikelihood:
No vertebral slippage seen on imaging.
No history of chronic mechanical back pain or neurological symptoms.
Herniated Nucleus Pulposus (HNP)
Reason for consideration: Common cause of back pain.
Reason for unlikelihood:
No radiating pain or neurological deficits.
No relief from supine position, which usually alleviates HNP discomfort.
