Spinal Tuberculosis In Children With Postoperative Kyphosis Formation Related Factors

Objective:Study of pediatric postoperative spinal tuberculosis kyphosis formation related factors.Methods:Retrospective analysis from 2002 January to 2013 June in our hospital were under the age of 14 with a complete preoperative clinical and radiological data and spinal tuberculosis in children patients clinical and imaging follow-up data. Kyphosis deformity in children cases were selected from the late, and were followed up for children. The follow-up results were analyzed, with a systematic research on the different age, different lesion location, lesion range, different therapeutic methods and prognosis of spinal kyphosis formation, to explore the related factors.Results:. A total of 35 patients with different degree of kyphosis, were followed up. Male 14 cases, female 21 cases; age 1-15 year old, average 6.75 years old; the course of 12-120 months, average 36.2 months. All patients underwent standing spine and lateral X ray film, CT and MRI diagnosis. Preoperative lesions were located in the cervicothoracic junction region 1 cases, thoracic vertebrae in 22 cases,11 cases of thoracic and lumbar,1 cases,1 cases involving 2 vertebral bodies,3-5 vertebral bodies in 14 cases,5 vertebral bodies in 20, Underwent anterior debridement and bone graft and internal fixation in 22 cases, simple posterior debridement bone graft and internal fixation in 13 cases.16 cases were complicated with nerve injury,6 cases of Frankel grade C grade 10 cases, D grade. Spinal tuberculosis recurred in 22 cases. Follow up at 9 years of age in 29 cases (83%), over 10 years old in 6 cases (17%).Conclusion:Cause of postoperative spinal tuberculosis kyphosis includes the following factors:the choice of treatment the patient’s age, surgery, the number of involved vertebrae protrusion deformity angle, at the beginning of treatment after the number of vertebral body completely lost and lesion location spinal level etc.
