Spinal tuberculosis accounts for almost 50% of all skeletal involvements. Global reconstruction with adequate debridement and decompression, all through posterior approach alone, is one of the surgical treatment modalities in the management of this disease. A 33-year-old female presented to our facility with lumbar tuberculous spondylitis; had 8-month history of low back pain and 4-month history of progressive low back swelling with associated fever, drenching night sweat, and progressive weight loss. She had a single-stage debridement and instrumented fusion via a posterior-only approach. She is ambulant with normal gait and gaining weight by the 1-year follow-up visit, with radiologic evidence of fusion. The posterior-only approach for 360° instrumented fusion is quite rewarding in the operative care of spinal tuberculosis.

| Introduction|| |
The spine is the most common site of skeletal tuberculosis as it accounts for almost 50% of all musculoskeletal involvements amongst the rather less common extra pulmonary manifestations of the disease. The lumbar spine remains the second most affected region of the vertebral column.
Chemotherapy with multidrug anti-tubercular treatment is the mainstay of care in Pott's disease and indications for surgery include: lack of response to chemotherapy, recurrence, static, or worsening neural deficit even after initiating chemotherapy, instability, incapacitating pain, and deformities. Circumferential reconstruction alongside adequate debridement and decompression, exclusively via the posterior approach, is one of the surgical treatment modalities in the management of spinal tuberculosis.
| Case Report|| |
A 33-year-old female with 8-month history of low back pain and 4-month of progressive lower back swelling. The pain visual analogue scale (VAS) score was 8/10. She had associated history of low-grade fever, drenching night sweat, progressive weight loss, and unpasteurized milk ingestion. There was occasional bilateral lower limb paresthesia and difficulty in walking due to the low back pain; however, there was no history of sphincteric dysfunction.
Examination revealed a chronically ill-looking young woman with a 16 × 16 cm hemispherical mass over the left Petit's triangle, non-tender and fluctuant with no differential warmth plus midline tenderness over the lower back. There was full power in all muscle groups except both hips with MRC (Medical Research Council) Grade 4/5. A clinical diagnosis of Lumbar Tuberculous Spondylitis was made. Pain radiographs and magnetic resonance imaging [Figure 1] and [Figure 2] showed extensive destruction of entire L4 vertebral body with inferior and superior end plates of L3 and L5, respectively, plus pre- and paravertebral collections with canal and nerve root compression. Four months after commencement of multi-drug anti-tubercular regimen she had a single-stage debridement plus abscess drainage, lumbar decompression and instrumented fusion with rod-pedicle screw construct and expandable inter-body titanium cage via a posterior-only approach from L2 to S1 [Figure 3], [Figure 4], [Figure 5].

The vertebral sequestrum sample for histology result further confirmed the diagnosis of Tuberculous Spondylitis. A significant clinical improvement was achieved as the Visual Analog Scale (VAS) score improved from eight (8) preoperatively to eventually zero (0) postoperatively enabling her to ambulate pain-free at 1-year follow-up [Figure 6] with radiologic evidence of stable fixation and bony fusion.

| Discussion|| |
Surgical approach in spinal tuberculosis has evolved from anterior to posterior. The anterior approach allows direct access to the infected focus and is convenient for debriding infection and reconstructing the defect. Nevertheless, in the lumbar region, attainment of bony stability through anterior instrumentation alone may be inadequate due to presence of the concomitant osteoporosis associated with infection of tuberculosis that renders the vertebrae structurally weak and thereby preventing adequate fixation. A combined anterior and posterior approach helps to overcome stability-related drawbacks of the anterior approach alone. However, it involves two surgeries—single event or staged procedure. When performed as a single event, it is associated with increased operative time and blood loss as well as exposure of vital structures such as peritoneum in already immunocompromised tuberculosis patients, predisposing them to further infection and additional morbidity.
In recent times, the posterior approach has been in the limelight because it is less invasive, allows circumferential cord decompression, and provides a strong three-column fixation via pedicle screws. The functional recovery evaluated in terms of VAS score in our index case is comparable to that of other workers and our patient was also pain-free during her last follow-up with radiologic evidence of stable fixation and fusion.
| Conclusion|| |
Single-stage decompression and instrumented fusion via a posterior-only approach may be an effective and safe procedure for surgical treatment of lumbar tuberculous spondylitis in young adults.
