The outcome of posterolateral fusion in highly selected patients with discogenic low back pain

Tuberculosis of the spine (Pott's disease) presenting as 'compression fractures'

STUDY DESIGN

Case reports and survey of literature.

OBJECTIVE

Case reports of two women with tuberculosis (TB) of the spine (Pott's disease) presenting with severe back pain and diagnosed as compression fracture are described. Physicians should include Pott's disease in the differential diagnosis when patients present with severe back pain and evidence of vertebral collapse.

SETTING

Ohio, USA METHODS: A review of the literature on the pathogenesis, pathophysiology, clinical presentation, diagnostic methods, treatment and prognosis of spinal TB was conducted.

RESULTS

After initial delay, proper diagnosis of spinal TB was made in our patients. Microbiologic diagnosis confirmed M. tuberculosis, and appropriate medical treatment was initiated.

CONCLUSIONS

Although uncommon, spinal TB still occurs in patients from developed countries, such as the US and Europe. Back pain is an important symptom. Vertebral collapse from TB may be misinterpreted as 'compression fractures' especially in elderly women. Magnetic resonance imaging scan (MRI) is an excellent procedure for the diagnosis of TB spine. However, microbiologic diagnosis is essential. Mycobacterium tuberculosis may be cultured from other sites. Otherwise, biopsy of the spine lesion should be done for pathologic diagnosis, culture and stain for M. tuberculosis. Clinicians should consider Pott's disease in the differential diagnosis of patients with back pain and destructive vertebral lesions. Proper diagnosis and anti-tuberculosis treatment with or without surgery will result in cure.
