Surgical and Health-related Quality of life Outcomes in Children With Congenital Scoliosis During 5-year Follow-up Comparison to Age and Sex-matched Healthy Controls

Abstract

<p><strong>Background: </strong>Congenital spinal anomalies represent a heterogeneous group of spinal deformities, of which only progressive or severe curves warrant surgical management. Only a limited number of studies have investigated the impact of surgery on the health-related quality of life and very limited data exists comparing these outcomes to healthy controls.</p><p><strong>Methods: </strong>A single surgeon series of 67 consecutive children with congenital scoliosis (mean age at surgery 8.0 y, range: 1.0 to 18.3 y, 28 girls) undergoing hemivertebrectomy (n = 34), instrumented spinal fusion (n = 20), or vertical expandable prosthetic titanium rib procedure (n = 13) with a mean follow-up of 5.8 years (range: 2 to 13 y). The comparison was made to age and sex-matched healthy controls. Outcome measures included the Scoliosis Research Society questionnaire both pre and postoperatively, radiographic outcomes, and complications.</p><p><strong>Results: </strong>The average major curve correction was significantly better in the hemivertebrectomy (60%) and instrumented spinal fusion (51%) than in the vertical expandable prosthetic titanium rib group (24%), respectively (P < 0.001). Complications were noted in 8 of 67 (12%) children, but all patients recovered fully during follow-up. Pain, self-image, and function domains improved numerically from preoperative to final follow-up, but the pain score was the only one with a statistically significant change (P = 0.033). The Scoliosis Research Society pain, self-image, and function domain scores remained at a significantly lower level at the final follow-up than in the healthy controls (P ≤ 0.05), while activity scores improved to a similar level.</p><p><strong>Conclusions: </strong>Surgery for congenital scoliosis improved angular spinal deformities with a reasonable risk of complications. Health-related quality of life outcomes improved from preoperative to final follow-up, but especially pain and function domains remained at a significantly lower level than in the age and sex-matched healthy controls.</p>
