Retroisthmic cleft refers to a cleft in the lamina and is rarely reported. It was first described by Brocher, and later Wick et al. proposed the term "laminolysis" to describe the retroisthmic cleft by analogy with the nomenclature of the applied stress fracture of the pars interarticularis (spondylolysis) and the pedicle (pediculolysis). In this paper, we describe two adolescent sports players with symptomatic lumbar laminolysis. Both improved significantly after adequate conservative treatment. Knowledge of laminolysis in adolescent patients with low back pain is necessary to avoid overlooking it and late diagnosis. For correct diagnosis, multidetector three-dimensional computed tomography (CT) is suggested. In addition, magnetic resonance imaging (MRI) also allows detection of inflammation in the defects.
峡部裂性裂指的是椎板裂，较为少见。它由 Brocher 首次描述，随后 Wick 等人通过类比关节突间（峡部裂）和椎弓根（椎弓根裂）的应用应力骨折的命名法，提出了“椎板溶解”这一术语来描述峡部裂性裂。本文描述了 2 例有症状的青少年运动性腰椎峡部裂患者，充分的保守治疗后，他们的症状均明显改善。对于腰痛的青少年患者，了解椎板溶解症有助于避免漏诊和延误诊断。为了正确诊断，建议使用多层螺旋 CT（MSCT）。此外，磁共振成像（MRI）也可以检测到缺损处的炎症。
