Pott's disease of the spine: findings from Sudan

ABSTRACT

Spinal tuberculosis is the commonest type of skeletal tuberculosis. It has variable presentations, but commonly presents with backache and weakness of lower limbs. Its prevalence is increasing world wide after the epidemic of HIV. To the best of our knowledge there are no studies addressing the clinical presentation of this disease in Sudan. In this study we included 84 patients with spinal tuberculosis. The study was conducted in two major hospitals in Khartoum in the period from January 2002 to December 2006. Results show males constituted 46 patients [54.8%] and females 38 [45.2%]. Their ages ranged between 16 years and 80 years, the mean age was 44.46 +/- SD 16.99. All patients had pain and or tenderness at the site of the lesion. Paraplegia or paraparesis was reported in 36 patients [42.8%], quadriplegia or quadriparesis in 25 [30%], Sciatica and root weakness in 22 [26.1%] and right brachial monoplegia in one patient. Evidence of active pulmonary tuberculosis was found in 15 patients [17.8%], abdominal tuberculosis in 7 patients [8.3%], lymphatic Tuberculosis in 1 patient [1.2%]. Cervical vertebrae were affected in a total of 26 patients [30.9%], the dorsal in 39 patients [46.4%] and the lumbar in 30 patients [35.7%]. One vertebra was affected in 3 patients [2.57%], 2 adjacent vertebrae in 48 patients [57.14%], 3 vertebrae in 24 patients [28.57%], 4 vertebrae in 4 patients [4.76%], 5 vertebrae in 1 patient [1.19%] and 6 vertebrae in 4 patients [4.76%].
