Introduction: Pediatric cervical spine implants and construction designs had rapidly evolved in the last decade. Anatomic and biomechanical differences between pediatric and adult cervical spine require a thorough preoperative planning, because these implants were originally designed for adults. The objective of this study was to assess the postoperative results of cervical instrumented fusion in children under 10 years old, and to describe the surgical technique and complications. Methods: Twenty-eight children with different cervical pathology treated with instrumented fusion were evaluated. The following procedures were used: Roy-Camille’s and Magerl’s techniques for lateral masses, Goel-Harms’ technique for C1-C2 fusion, and occipital-cervical fusion with occipital plates or screws. Inclusion criteria were: children under 10 years, no prior spine surgery, and minimum follow-up of 2 years. Results: Sample included 17 girls and 11 boys, with a mean follow-up of 3.8 years (range 2-10). Mean age was 6.1 years (range: 1.6-10). Overall complication rate was 32.1%. The highest complication rates were associated with: genetic syndromes [6 cases (21.4%)], skeletal dysplasias [3 cases (10.7%)]. Thirteen patients were <6 years, 7 of them had complications (53.8%). Conclusions: Cervical instrumented fusion in patients <10 years old proved to be a feasible and safe surgical procedure. Vertebral dysplasias, congenital, syndromic anomalies, and being younger than 6 years old are the main factors associated with high complication rates.
