Average Correction of Cobb’s Angle in Congenital Scoliosis Using Growing Rode as a Mode of Correction

Abstract

Introduction: Scoliosis with rotational imbalance is mainly characterized by the vertebral rotation related to the curve in the coronal plan. Aims and objectives: The basic aim of the study is to assess the average correction of Cobb’s angle in congenital scoliosis using growing rode as a mode of correction. Material and methods: This descriptive study was conducted in DHQ hospital Sargodha during 2019 to 2021 for the period of two years. The data was collected with the permission of ethical committee of hospital. The data was collected from 12 patients from age range 4-12 years. Among that 12 patients there were 7 male and 5 female patients. We carried out a convenience sampling, including all scoliosis patients who received surgical treatment with elongating rods in the period studied, and excluded all patients diagnosed with syndromic scoliosis, and with incomplete records in their clinical history. Results: There were 12 patients of scoliosis under 10 were reviewed. Of these, 35 (5%) required surgical treatment with growing rods and met the selection criteria. The presurgical and postsurgical radiographic change showed a 47.7% reduction in the Cobb angle (31.8° ± 14.6° difference), which was statistically significant (p<0.001; t-student). During the study period, 8 patients showed some procedure-related complication; another 2 patients (22.9%) showed instrumentation failures, and 2 cases (5.7%) showed infection in the operated area which, it should be noted, was associated with instrumentation failure. Univariate analysis was performed to define which variables could be potential predictor factors of complications in our patient sample. Conclusion: Treatment of scoliosis in patients under age 10 with growing rods has achieved a significant reduction in the magnitude of the deformity before final bone fusion.
