Scheuermann's disease is a rigid progressive kyphosis occurring in late childhood to adolescence. It is the most common cause of sagittal imbalance and angular progressive kyphosis in adolescents associated with back pain. The exact etiology of the disease is unclear, but it is characterized by defective growth of the end plate that may result from excessive mechanical stress on a weakened end plate during spinal growth. Several other theories have been proposed, and it is thought to be a multifactorial disease occurring as a result of the interplay of multiple factors. The radiographic features consist of anterior vertebral body wedging, irregular end plates, Schmorl's nodes, and intervertebral disk degeneration. The natural history and evolution of this disease is also unknown. Conservative management with physiotherapy, rehabilitation, and bracing is the first line of treatment. Mechanical bracing helps prevent further progression of the kyphotic deformity. Surgery is mostly indicated in patients with failure of conservative management, with neurologic compromise, and for cosmetic reasons.

休门氏病是一种发生在儿童晚期至青春期的僵硬进行性脊柱后凸。它是与背痛相关的青少年矢状不平衡和角度进行性后凸的最常见原因。该疾病的确切病因尚不清楚，但其特征是终板生长缺陷，这可能是由于脊柱生长过程中弱化终板受到过度机械应力所致。还提出了其他几种理论，认为它是一种多因素疾病，是多种因素相互作用的结果。放射学特征包括前椎体楔入、不规则终板、许莫尔结节和椎间盘退变。这种疾病的自然史和进化也是未知的。物理治疗、康复和支撑等保守治疗是第一线治疗。机械支撑有助于防止后凸畸形的进一步发展。手术主要适用于保守治疗失败、神经系统损害以及出于美容原因的患者。
