SURGICAL OUTCOME OF SPINAL DEFORMITIES IN CHILDREN UNDER 10 YEARS OF AGE – A RETROSPECTIVE REVIEW

Abstract

Introduction: Spinal deformities (scoliosis, kyphosis or kyphoscoliosis) in children under 10 years of age result from congenital, neuromuscular and idiopathic etiologies. The progression of the deformity is affected by its nature, location and age of onset. Spinal arthrodesis is the procedure of choice in patients with progressive deformities. The use of instrumentation facilitates curve correction and arthrodesis rates. Pediatric spinal surgery is technically demanding, and is still considered controversial. The advent of reduced size spinal instrumentation allowed surgeons to expand their use to pediatric patients. The use of spinal instrumentation in children with various spinal deformities has not been well documented.

Objective: To assess the safety and efficacy of spinal arthrodesis in young patients with progressive spinal deformities.

Patients and Methods: We retrospectively reviewed the medical charts and radiographs of 25 patients younger than 10 years of age who underwent corrective surgery for various spinal deformities. Radiographic outcome, fusion rates and complication were compared between instrumented and non instrumented patients.

Results: At two years of follow up instrumented corrective procedures resulted in superior correction compared to non-instrumented patients and in solid arthrodesis in all. Complications were infrequent.

Conclusions: The use of reduced size spinal instrumentation in young patients with progressive spinal deformities is safe and effective. Curve correction, length of bracing and fusion rates are all in favour of instrumentation, wile complication rates are acceptable. The use of spinal instrumentation in young patients requires expertise and patience.
