English Abstract:

  【Abstract】 Objectives: To summarize the reasons of re-operation for pediatric spinal tuberculosis. Methods: A retrospective analysis of 123 cases with pediatric spinal tuberculosis from June 2002 to June 2013 and undergoing surgical treatment was reviewed. Among them, there were 59 males and 64 females; age ranged from 1 to 14 years(mean 6.9 years). There were 76 cases undergoing anterior operation, 26 cases undergoing posterior operation and 21 cases with combined anterior and posterior operation. The reasons of re-operation were reviewed retrospectively. Results: Among 123 cases with pediatric spinal tuberculosis, 27 patients underwent re-operation, there were 15 males and 12 females; age ranged from 2 to 13 years(mean 8.2 years). Delayed healing of spinal tuberculosis was noted in 5 cases, kyphosis was noted in 14 patients, instrument failure was noted in 4 cases, recurrence of spinal tuberculosis accompanied by instrument failure was noted in 1 case, delayed healing of spinal tuberculosis accompanied by kyphosis was noted in 2 cases, postoperative instrument failure accompanied by kyphosis in 1 case. Anterior re-operation was performed in 19 cases, posterior re-operation in 4 cases, combined anteropsterior re-operation in 4 cases. Incidence of postoperative kyphosis showed significant difference among three groups(P<0.05), postoperative re-operation, delayed healing and recurrence rate showed no significant difference among three groups(P>0.05). The difference was satistically significant with respect to the instrument failure after operation(P＜0.05). Conclusions: Postoperative kyphosis, delayed healing, recurrence and instrument failure are the main causes of re-operation for pediatric spinal tuberculosis. Anterior approach has higher rate of re-operation than posterior and combined anteroposterior approach.
