RESUMO
STUDY DESIGN: Analysis was based on radiographic appearance of 57 cases of congenital scoliosis and associated anomaly PURPOSE: The aim of the present study was to assess the incidence, morphology and the associated anomalies of the congenital spinal scoliosis. SUMMARY OF LITERATURE REVIEW: Hemivertebra is the most common type of congenital scoliosis and urogenital, musculoskeletal and cardiac anomalies are strongly associated. MATERIALS AND METHODS: The authors analysed the morphology and the associated anomalies of 57 cases of congenital scoliosis from 1994 to 2000. RESULTS: It was more common in male(32 males and 25 females). The bony anomalies were classified as failure of formation(40cases, 70.2%), failure of segmentation(11cases, 19.3%) and mixed type(6cases, 10.5%). Of the failure of formation, there were 36 cases(63.2%) of hemivertebra, 2 cases of posterior quadrant vertebra and 2 cases of wedge vertebra. We found associated anomalies in 26 patients(45.6%). Associated cardiac anomalies were 2 dextrocardia, ventricular septal defect, atrial septal defect and patent ductus arteriosus. Associated musculoskeletal anomalies were 5 rib fusion, 2 developmental dysplastic hip, 3 Klippel-Feil syndrome, Achondroplasia, Arnold-Chiari malformation, spinal dysraphism with sacral hair patch, cleft palate with congenital anklyloglossia. Associated neurogenic anomalies were 2 cases of syringomyelia and 3 mental retardation. There were unilateral renal agenesis and undescended testicle in urogenital anomalies. CONCLUSIONS: Common type of the congenital scoliosis was hemivertebra(63.2%) caused by the failure of formation(70.2%). Associated anomalies were found in 26 patients(45.6%).
