Luaran Klinis Teknik Operasi Single Rod Global Derotation pada Kasus Adolescent Idiopathic Scoliosis di RSUP Haji Adam Malik Medan Tahun 2016-2020

Abstract

Introduction: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine on the coronal, sagittal, and axial sides. AIS is the most common case of scoliosis, counted for 80% of pediatric scoliosis cases. Surgical management of AIS continues to evolve to find the optimal correction system and must be able to correct the existing deformity. Single rod derotation (SRD) is one of the most commonly used surgical techniques to correct spinal deformities. Aims: To determine the clinical outcome of the SRD surgical technique in AIS at Haji Adam Malik General Hospital Medan. Methods: A retrospective cross-sectional study was conducted in 2016-2020 at Haji Adam Malik General Hospital Medan. The subjects in this study were AIS patients who had undergone surgery with the SRD technique and had complete medical record data including demographic data, onset, kyphosis angle before and after surgery, and Cobb angle before and after surgery. Results: This study involved 23 female AIS subjects with a mean age of 16.09 years. The most common Lenke-based diagnoses were AIS Lenke 1 (52.2%), followed by AIS Lenke 3 (26.1%), AIS Lenke 6 (13%), and AIS Lenke 4 and 5 (4.3%). In this study, there were no patients with AIS Lenke 2. The average change in the angle of kyphosis before and after surgery showed significant results (25.830 VS 15.910 p<0.001) with a mean correction of 31.82%. There was a significant difference in the mean Cobb angle before and after SRD surgery (67.260 vs 34.870, p<0.001). SRD correct the Cobb angle with an average of 48.69%. The mean blood volume during SRD surgery was 393.48 ml with an average surgical duration for 249.13 minutes. Conclusion: The SRD technique significantly improves the kyphosis and Cobb angles so that it can be a good surgical option for patients with AIS.
