SPINAL TUBERCULOSIS IN TWO CENTRES: A DIFFERENT ANIMAL?

Objective: To compare the presentation, diagnosis and treatment of spinal tuberculosis in two cities, one in the UK, and one in Malaysia Design: Retrospective comparison over a five-year period from June 1995. The Centres studied were the Royal Orthopaedic and Queen Elizabeth Hospitals, Birmingham (UK), and the Kuala Lumpur General Hospital (KL), Malaysia. Subjects: There were 80 patients (29 females, mean age 42) in the KL group, and 19 patients (8 females, mean age 45) in the UK group. Outcome measures: Frankel grading before and after treatment were measured for both groups. Results: KL patients had higher rates of immunocompromise, and had fewer spinal levels involved, 2.1 compared with 2.6 (p-−0.04). There were 65 procedures, 58 positive ZN stains, and 65 positive cultures as compared with 24, 2 and 9 in Birmingham respectively. Improvement in Frankel grading was seen in four patients in UK (5 grades), and in 17 patients in KL (29 grades). Conclusions: Although the two groups exhibited similar demographics, the rate of immunocompromise-related tuberculosis, severity of neurological deficit, and type of surgery undertaken differed significantly. Reasons for the difficulty in identifying the tubercle bacillus in Birmingham are discussed.
