[Tetanus osteoarticular complications in Dakar]

To assess the epidemiological and clinical features of osteoarticular symptoms during tetanus infection, we carried out a retrospective study in infectious Diseases Ward of the University Teaching Hospital in Dakar (Senegal). Over a period of 7 years (1990-1996), 1, 199 cases of tetanus of more than 1 month of age were diagnosed. Among those who survived (n = 948), 18 cases of osteo-articular manifestations were observed (1.8%): 15 presented with vertebral fracture located within the thoracical part T4-T8 (83.3%) while 3 patients had para-articular osteoma in the elbows (16.7%). These complications occurred on stage II (89%) and stage III (11%) of Mollaret's classification of tetanus infection. Males were more represented than females (sex-ratio = 5) and the median age was 13 years (range = 6-45 years). The mean hospitalisation duration was significantly higher for patients with para-articular osteoma (6 weeks) than for those with vertebral fracture (3 weeks). No major functional impairment was noticed during hospitalisation and patients required only physiotherapy and clinical and radiological surveillance. Although not frequent and of some little functional consequence, osteoarticular complications of tetanus, should invite to improve the antitetanic immunization strategies in developing countries.
