Abstract
Aim
To evaluate efficacy of a one stage posterior approach in decompression and eradication of infection in TB spine.
Background
The classic operation for TB spine is anterior spine debridement. This involves a trans-thoracic, or retroperitoneal approach, thus increasing morbidity in an already compromised patient. The anterior procedure in the form of the Hong Kong operation is aimed at decompressing the spine, and debridement of necrotic tissue. If kyphosis is a major problem, its correction requires a posterior procedure, often not at the same sitting.
Material and Method
A retrospective review of patients treated surgically for TB Spine during the time period 2009–2012. We examined the records of those patients that were treated by a posterior only approach. We took note of the demographics of the patients. We measured the efficacy of the decompression by measuring the pre op and post op neurologic status as measured by the Frankel grading. The efficacy of debridemide was assessed by measuring the preoperative and follow up ESR.
Results
We identified 11 patients for review, 8 male and 3 females. 8 were HIV positive. The disease affected the thoracic spine. The average follow up was 12 months. There was good correction of the deformity and this was maintained throughout the follow up period. The ESR decreased in all the patients. Neurologic improvement was noted in 5 patients and no patients deteriorated. Statistical methods to quantify these changes were not significant because of the small numbers.
Conclusion
In our environment a number of patients are immunocompromised by the HIV virus. A trans thoracic approach increases the morbidity in these patients. Effective decompression and debridement can be achieved by the posterior only approach.
