Does the Fixation Span Impact on Results of Surgical Correction of Pediatric Congenital Spine Deformities? Analysis of a Monocentric Cohort

Abstract

<jats:title>Abstract</jats:title> <jats:p><jats:bold>Background: </jats:bold>We aimed at reviewing results of surgical correction of congenital spinal deformity with regard to length of instrumentation and type of osteotomy.<jats:bold><jats:italic>Methods.</jats:italic></jats:bold> Study comprised 117 patients with congenital spinal deformity treated between 2010 and 2018. Patients’ aged 1 to 18 years. Mean follow-up was 3 years (1 to 8). Posterior approach was used in all cases. Patients were subdivided into 4 groups.<jats:bold>Result: </jats:bold><jats:bold><jats:italic>Monosegmental unilateral fixation (Group I) f</jats:italic></jats:bold>or 15 children with mean age of 48.3 months. Cobb angle for scoliosis and kyphosis were 31.1° and 29.3° corrected to 74.9% and 84.0% respectively. Blood loss was 213.6 mL. Operating time was 165 minutes.<jats:bold>Monosegmental bilateral fixation (Group II) </jats:bold>for 24 patients with mean age of 53.1 months. Cobb angle for scoliosis and kyphosis were 32.5° and 30.9° corrected to 83.7% and 100.6% respectively. Blood loss was 215.4 mL. Operating time was 160.5 minutes.<jats:bold>Three segmental bilateral fixation (Group III)</jats:bold> for 29 patients with mean age of 78.2 months. Cobb angle for scoliosis and kyphosis were 36.6° and 37.6° corrected to 83.1% and 86.7% respectively. Blood loss was 342.7 mL. Operating time was 197.0 minutes. <jats:bold><jats:italic>Polysegmental bilateral fixation (Group IV) </jats:italic></jats:bold>for<jats:bold><jats:italic> </jats:italic></jats:bold>49 children with mean age of 112.7 months. Cobb angle for scoliosis and kyphosis were 40° and 58.2° corrected to 72.5% and 81.6% respectively. Blood loss was 549.3 mL. Operating time was 288.8 minutes.C<jats:bold>onclusion: </jats:bold>Choice of spinal fixation technique was determined on the basis of patient’s age, magnitude of the deformity and concomitant vertebral abnormalities.</jats:p>
