Purpose
Various surgical methods have been described for the management of lumbar tuberculous spondylitis in the literature. However, there were few reports on the two-stage surgical treatment of lumbar tuberculosis in children of elementary school age. We present a retrospective clinical study of 14 patients with lumbar and lumbosacral tuberculous spondylitis treated by two-stage surgery (first stage: posterior instrumentation; second stage: anterior debridement and allografting). The purpose is to determine the clinical efficacy of such surgical treatment for lumbar tuberculosis in children.
Method
Our series was comprised 9 males and 5 females with an average age of 7.5 years treated with the abovementioned surgical procedure. All patients had lumbar and lumbosacral involvement with one patient having spondylitis at L2–3, three at L3–4, seven at L4–5, and three at L5–S1. All patients had single motion segment involvement. The Frankel scoring system was used to assess the neurological deficits. Frankel’s grade B in two patients, grade C in four and grade D in eight. The following data were followed-up for an average period of 50.1 months (42–64 months) in these patients: healing of disease, deformity correction and its maintenance, neurologic function, and spinal bony fusion.
Results
The average preoperative local deformity angle was −13.8°, correcting to 3.4° postoperatively and 1.5° at the final follow-up. With the exception of one patient who received a D at the final follow-up, all cases obtained complete neurological recovery. No breakage and looseness of internal fixation was found. Bony fusion was achieved in all cases within 6 months postoperatively. There was no recurrent tuberculous infection.
Conclusion
Two-stage (posterior and anterior) surgery is a safe and effective procedure for the patient of elementary school age suffering from lumbar and lumbosacral tuberculous spondylitis, especially for the patients in poor general condition. The procedure has the advantage of minor surgical invasion, effective kyphosis correction and less complications.
