Traditional treatments of early onset spine and chest wall deformity, such as spinal fusion, focused on the vertebral column deformity and often restricted growth of the spine.

早发性脊柱和胸壁畸形，如脊柱融合术，专注于脊柱畸形和脊柱的增长，往往局限于传统的治疗方法。

Another diagnosis to consider is a closed spinal dysraphism, where the vertebral arches are not fused well, but there is no vertebral column agenesis.

另一种鉴别诊断是闭合性的脊髓椎管闭合不全，同样椎弓没有融合，但没有脊椎发育不良。

Therefore, the dwarf mutation in X. helleri is caused by the developmental defect in spinal column, and the vertebral malformation underlies the body type alteration anatomically.

因而推测，剑尾鱼的侏儒突变是由于脊椎的发育缺陷所致，椎体异常是其体型变化的结构基础。
