Bone tuberculosis: results and experience in Leicestershire

Management of tuberculosis falls to the thoracic physician and includes extrapulmonary sites. We have conducted a survey of notification of bone tuberculosis in Leicestershire from 1978 to 1983 inclusive. Eighty-one cases were notified, 75 were traced and 69 confirmed tuberculosis (mean age 40.2 years, 39 male, 54 from the Indian sub-continent (ISC)). Mean length of symptoms was 8.4 months, the commonest being pain and swelling. The diagnosis was established by evidence of bone involvement plus at least one of the following: positive Heaf test (54/56), positive culture at bone sites for Mycobacterium tuberculosis (45/47), or suggestive histology (30/34). There were no resistant organisms. Chemotherapy (mean duration 16.2 months) was well tolerated. Spine was the site most often involved (37 patients, 34 ISC), with abscess formation common (17 patients). Four who presented with spinal cord compression received a mean of 8 months' bed rest, three required decompression and one died. No patient developed new neurological signs on treatment. Fourteen others received an average of 2.3 months' bed rest. In this predominantly ISC immigrant population, spinal tuberculosis is common but does not progress to cord compression on treatment. For those without cord compression the course and outcome were similar whether or not they were treated with bed rest.
