Abstract
Objective. To study the effect of modern methods of spinal instrumentation for treatment of tuberculous spondylitis on growth of vertebrae after deformity correction in extensively growing children.
Material and Methods. A total of 28 preschool age children were operated on for tuberculous spondylitis complicated by kyphosis exceeding 50°. Eight patients were operated on without posterior instrumentation, 20 patients - with additional posterior compressive implants. More than one year follow-up included assessment of the following metric parameters: anterior and posterior vertical size of fusion, anterior and posterior vertical size of the intact vertebra caudal to the anterior fusion inside and outside the instrumented zone.
Results. Degenerative changes in the initially intact spinal motion segments within fixation zone were observed for 2 years after surgery in 17 out of 20 patients operated on with posterior instrumented fixation. These changes were presented by a sharp decrease in the intervertebral disc height and by a sclerosis of adjacent end plates.
Conclusion. Children operated on with application of modern implants have not still reach the age of the growth stop, though follow-up periods are sufficiently long. This does not allow predicting the spine development in the adolescence.
