Profile films of the lumbar region show the vacuum-disc phenomenon fairly frequently especially at the L5-S1 level and when there is disc degeneration. Two varieties can be distinguished : one with a well-defined enlarged medial image, and a more limited type which is often anterior, at the fibrous ring level and in contact with the vertebral plates. The latter is seen less frequently, but needs to be considered, as it precedes the changes seen in the nucleus pulposus in the intersomatic alteration. It has been shown that this image is of gaseous origin. It is caused by the liberation of gas into a newly-formed intersomatic cavity situated either in the nucleus pulposus or fibrous ring levels. The vacuum-disc phenomenon is of great diagnostic value as it is usually found in relation to degenerated discs and permits orientation of diagnosis towards classical arthrosis or Pott's pseudo-arthrosis when atypical radiological images are seen.

Of the three major areas of the spinal column, the cervical spine is least commonly infected; approximately 3 to 5 per cent of all spinal infections involve the cervical spine. Tuberculous, pyogenic, fungal, and parasitic infections may involve the cervical spine and occur in this order of decreasing frequency. Difficulty in differential diagnosis most commonly involves tumor. Fungal and parasitic infections of the cervical spine are extremely rare, but fungal infections have been increasing over the past three decades. Clinical suspicion, radiologic examination, and definitive diagnosis via tissue biopsy are necessary so that definitive procedures can be instituted. Specific antibiotic coverage, surgery to facilitate the body's defenses and antibiotic penetration, and stabilization of the spine are the most important therapeutic measures to be instituted.
Tuberculous spondylitis treatment in developing nations remains controversial. We report our experience, working in a Center where appropriate medical and human structures are available. 22 of 78 adults treated at Jeanne-Ebori Hospital (Gabon), for tuberculous spondylitis, between August 1982 and June 1992, underwent surgery. The average age was 48 years (range, twenty-six to sixty-eight years). Eighteen patients had neurological complications: progressive spinal cord lesions: 15 cases (tetraplegia: 3, paraplegia: 11, tetraparesis: 1) and radicular syndromes (3 cases). The patients were seen in advanced stages of the disease with bone destruction, associated with collapse of vertebrae in ten cases. Indications for surgery were: neurologic in eleven cases, mechanical in one case, and mixed in ten cases (neurologic and mechanical: 5, etiologic and mechanical: 3, etiologic and neurologic: 2). Anterior approach were performed in 10 cases, posterior approach in 12 cases, generally, following an initial three weeks course of antituberculous therapy. The average length of time spent in hospital including rehabilitation had been 10.4 weeks. The average follow-up was 23.7 months (range: 8 months to 8 years). All patients obtained fusion, and stability was achieved after 3-5 months. The neurological recovery was complete in 9 cases, partial in 8 cases, unchanged in one case. All patients were considered medically cured. The analysis of material and socio economic difficulties obliges us to reduce the treatment length by favoring surgical intervention in relatively advanced lesions. Moreover, that allows to specify the diagnosis.

OBJECTIVE: To describe the rheumatic conditions found in skeletal remains of Amerindian ancestry disinterred from a 16th century Mexican cemetery. METHODS: A physical anthropologist and 2 rheumatologists surveyed the recovered skeletal remains. RESULTS: We examined the skeletal remains of 443 subjects. We found 19 cases of Pott's disease, 17 of osteoarthrosis in various anatomical locations, 2 spondyloarthropathies, probably ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis, one probable septic arthritis in the stemoclavicular joint, and 2 compression fractures of the spine. We found no cases of gout or rheumatoid arthritis. CONCLUSION: This is the first report on the presence of rheumatic conditions in colonial Mexico. Studying the remains of these populations can provide useful information about the origin and evolution of different rheumatic conditions.
