The axes of the kidneys in children with a thoracolumbar gibbus deformity may be distorted to simulate a horseshoe kidney. Measurements of the angle of the gibbus and the angle of intersection of the renal axes were made in 68 children with thoracolumbar meningomyelocele. Thirty-eight children with a gibbus deformity and thoracolumbar meningomyelocele had an abnormality of the renal axis on supine urography, including 19 (28 per cent) in whom a horseshoe kidney was suggested. Three additional children with a gibbus deformity and thoracolumbar meningomyelocele had a normal renal axis. Regression analysis of these data indicated a linear relationship between the angle of the gibbus and the amount of deviation of the renal axis for the values studied. Nuclear scintigraphy, ultrasound studies and clinical records were reviewed in all 41 children with a gibbus deformity. In none were the kidneys fused. There were 21 children with thoracolumbar myelomeningocele who had no gibbus deformity and a normal renal axis. Six other children will be described in detail, 2 of whom were excluded because of severe scoliosis and 4 with congenital renal anomalies.
患有胸腰段脊柱后凸畸形的儿童，其肾脏的轴线可能会扭曲，类似马蹄肾。对68例胸腰段脊髓脊膜膨出患儿进行了脊柱后凸角度及肾轴交叉角度的测量。38例患有脊柱后凸畸形和胸腰段脊髓脊膜膨出的患儿在仰卧位尿路造影时出现肾轴异常，其中19例（28%）提示为马蹄肾。另外3例患有脊柱后凸畸形和胸腰段脊髓脊膜膨出的患儿肾轴正常。对这些数据的回归分析表明，在所研究的数值范围内，脊柱后凸角度与肾轴偏差量之间存在线性关系。对所有41例患有脊柱后凸畸形的患儿的核素扫描、超声检查及临床记录进行了回顾。均未见肾脏融合。有21例胸腰段脊髓脊膜膨出患儿无脊柱后凸畸形且肾轴正常。另外6例患儿将详细描述，其中2例因严重脊柱侧弯被排除，4例有先天性肾脏异常。
