Abstract:
BACKGROUND:Thoracic vertebrae connected with the ribs of corresponding segments constitute the thorax. Because of thoracic vertebrae deeply and complicated structure, it is difficult to operate or to expose thoracic vertebrae completely. The traditional anterior ways can thoroughly remove the focus and achieve a good internal fixation, but this treatment needs to cut the rid. The surgeon discovered in years of clinical practice that distraction of intercostal space without cutting off the ribs could completely remove the focus and achieve fixation and fusion. OBJECTIVE:To explore the feasibility, advantages and disadvantages of anterior plate fixation and autologous bone graft fusion in the repair of thoracic spinal tuberculosis.
METHODA total of 30 cases of thoracic spinal tuberculosis were enrol ed. On the base of traditional thoracic spinal anterior surgical approach, the rib was reserved. Anterior distraction device was used to open the ribs for clearance and to move the focus of thoracic spinal tuberculosis. Autologous ilium was obtained and subjected to fusion and anterior plate fixation. Visual Analog Scale, Oswestry Disability Index, Frankel grade and Bridwel bone healing rating were used before and after treatment.
RESULTS AND CONCLUSION:A total of 30 patients were fol owed up for 3-60 months. The bone healing (class A) was seen, but no fistula formation was visible. Nerve compression symptoms were improved, without aggravating cases. Postoperatively, the average Cobb angle correction was 10.32°. After 6 months, imaging revealed bone fusion of affected vertebral body. After 18 months, the vertebral height was not lost obviously, no recurrence of vertebral tuberculosis. These results indicated that anterior intercostal space without cutting ribs exposed clearly, showing a large space, where can meet the requirement of first-stage debridement fixation and fusion in the repair of thoracic tuberculosis. The pathological changes were visibly clear;the focus was thoroughly removed, and the ribs were reserved. The outcomes are identical to rib resection. Simultaneously, autogenous iliac trilateral cortex has good supporting effects. Loose cancellous bone mesh has good osteogenesis and is helpful to bone healing.
