There are 2 fairly common types of spondylolisthesis in children - dysplastic and isthmic. The dysplastic type is secondary to congenital defects at the lumbosacral joint. The isthmic is usually due to a fatigue fracture of the pars interarticularis but there is also an hereditary element in this type. Most children with spondylolisthesis never develop significant symptoms and even of those who do, the vast majority can be treated without surgery. If symptoms persist or if further olisthesis is occurring, a one-level spinal fusion done through a paraspinal approach is recommended. It is most important not to allow olisthesis to develop to the point that the child shows the cosmetically undesirable stigmata characteristic of the condition. Solid fusion can be obtained in every case and will stop further slip.
儿童中存在两种相当常见的脊椎滑脱类型——发育不良型和峡部裂型。发育不良型继发于腰骶关节的先天性缺陷。峡部裂型通常是由于关节突间部疲劳性骨折，但此类型也存在遗传因素。大多数脊椎滑脱儿童从未出现明显症状，即使出现症状的儿童，绝大多数也可通过非手术治疗。如果症状持续或出现进一步滑脱，建议采用经椎旁入路进行单节段脊柱融合术。最重要的是不要让滑脱发展到使儿童出现该病症在外观上令人不悦的特征。每种情况都能实现牢固融合，并能阻止进一步滑脱。
