Abstract
Background: Congenital kyphosis is a spinal deformity resulting from disruption in the formation of the anterior part of the vertebrae on the sagittal plane during early fetal development. Understanding demographic trends and associated anomalies in affected individuals within specific regions and countries is pivotal for tailoring more suitable treatment approaches within these patients.
Methods: This retrospective cross-sectional study was conducted on 108 patients referred to Shafa Yahyaian Hospital in Tehran between 2010 and 2019. Demographic and radiological criteria were assessed in all patients who underwent surgery for congenital kyphosis at this hospital. Parameters such as age, gender, BMI, presence of cardiac, urogenital system, and spinal anomalies, kyphosis type, as well as Cobb's angle before and after surgery, were gathered, reviewed, and analyzed from patients' records.
Results: Of the cohort, 74 patients were categorized as congenital kyphosis type 1, 21 as type 2, and 13 as type 3, encompassing 69 female (63.9%) and 39 male patients (36.1%). The mean age at the time of examination and symptom onset was 6.5 years, while the mean age at the time of surgery was 16.5 years. Notably, 38 patients exhibited a cardiac anomaly, 14 had genitourinary system anomalies, and 39 presented with spinal anomalies. A statistically significant correlation existed between the presence of a cardiac anomaly and the type of congenital kyphosis, with type one exhibiting a markedly higher incidence of cardiac anomalies compared to the other two types.
Conclusion: The findings revealed a higher frequency of type 1 congenital kyphosis. Moreover, patients with type 3 congenital kyphosis underwent surgery at a significantly younger age than those with the other two types, potentially attributed to its higher progression rate. Spinal cord, cardiac, and genitourinary tract anomalies were respectively observed as the most prevalent anomalies among the patients.
