1. The long-term results of 740 European patients suffering from spinal tuberculosis and treated without and with specific anti-tuberculous drugs have been surveyed. 2. The results of treatment by conservative methods and by conventional surgical methods have been compared in the two periods. The attainment of spinal stability as judged by serial examination of radiographs was the main criterion in assessing healing. 3. Although the results of conventional treatment have improved since the advent of chemotherapy, the credit is mainly due to the influence of more frequently and more expertly applied operations. 4. With chemotherapy the well tried medical and surgical procedures produce stable spines in three-quarters of cases. With early operation on the lesion the results are better and more quickly obtained. Of eighty spines on which focal surgery was performed during the past twelve years before the lesions had become extensive, seventy-seven (9·62 per cent) healed by bone. The average duration of hospitalisation after such operation was four and a half months. No patient has had to be readmitted. 5. The difficulties and possible dangers of these methods must be emphasised. The operations are difficult and dangerous when the lesions have been allowed to get out of hand and become unduly extensive. They are contra-indicated in cases where there is very marked deformity. 6. Training in special techniques of operation is necessary. Duplicated drainage of the hemithorax after thoracotomy is essential, and skilled after-care is important if good results are to be obtained.
In spinal tuberculosis MRI can clearly demonstrate combinations of anterior and posterior lesions as well as pedicular involvement. We propose a classification system, using information provided by MRI, to help to plan the appropriate surgical treatment for patients with thoracic spinal tuberculosis. We describe a series of 47 patients, divided into four groups, based on the surgical protocol used in the management. Group A consisted of patients with anterior lesions which were stable with no kyphotic deformity, and were treated with anterior debridement and strut grafting. Group B comprised patients with global lesions, kyphosis and instability who were treated with posterior instrumentation using a closed-loop rectangle with sublaminar wires, and by anterior strut grafting. Group C were patients with anterior or global lesions as in the previous groups, but who were at a high risk for transthoracic surgery because of medical and possible anaesthetic complications. These patients had a global decompression of the cord posteriorly, the anterior portion of the cord being approached through a transpedicular route. Posterior instrumentation was with a closed-loop rectangle held by sublaminar wires. Group D comprised patients with isolated posterior lesions which required posterior decompression only. An understanding of the extent of vertebral destruction can be obtained from MRI studies. This information can be used to plan appropriate surgery.
We have reviewed 74 tuberculous hips in 73 children treated from 1950 to 1991. From 1979 to 1991 we treated 28 patients with rifampicin, isoniazid and pyrazinamide given for nine months (series A), using active mobilisation for the more recent cases. Before this, 46 hips had been treated with streptomycin and isoniazid with or without para-aminosalicyclic acid given for a mean of 18 months (series B), and all these patients were immobilised for a mean of 2.2 years. The radiological appearances at presentation as classified by Shanmugasundaram (1983) predicted the outcome. Most hips were of the 'normal' type (50% and 59% of series A and B respectively) followed by the dislocating type (25% and 13%) and the atrophic type (8% and 9%). There were good or excellent results in 93% of the 'normal' type. All the atrophic type had poor results. The dislocating type had a poor result if the joint space was narrow after reduction of the hip. Early mobilisation had no effect on the outcome of the 'normal' type of disease. The newer drug regimens allowed for shorter courses of treatment, but did not necessarily give a better outcome.
We performed a randomised, controlled clinical trial to compare ambulant short-course chemotherapy with anterior spinal fusion plus short-course chemotherapy for spinal tuberculosis without paraplegia. Patients with active disease of vertebral bodies were randomly allocated to one of three regimens: a) radical anterior resection with bone grafting plus six months of daily isoniazid plus rifampicin (Rad6); b) ambulant chemotherapy for six months with daily isoniazid plus rifampicin (Amb6); or c) similar to b) but with chemotherapy for nine months (Amb9). Ten years from the onset of treatment, 90% of 78 Rad6, 94% of 78 Amb6 and 99% of 79 Amb9 patients had a favourable status. Ambulant chemotherapy for a period of six months with daily isoniazid plus rifampicin (Amb6) was an effective treatment for spinal tuberculosis except in patients aged less than 15 years with an initial angle of kyphosis of more than 30° whose kyphosis increased substantially.
1. The results of ischio-femoral arthrodesis for tuberculous arthritis of the hip in thirty-five adults and in twenty-nine children are reported. The "blind" technique of Brittain was used in thirteen patients and the open technique in fifty-one. 2. Bony fusion was obtained by the first operation in thirty-three out of the thirty-five adults and in twenty-three out of twenty-nine children. In children strikingly better results were gained from the posterior open technique than from the original "blind"technique of Brittain. 3. There was no evidence that ischio-femoral arthrodesis in children interfered with the growth of the limb.
1. The anatomical and physiological principles underlying the operation of ischio-femoral arthrodesis by an anterior approach are discussed. 2. The technique of the operation is described.
