Spondylolysis is characterized by a posterior defect in the vertebral body, specifically at the pars interarticularis. Typically, this defect is a consequence of trauma or persistent repetitive loading and hyperextension. When this instability causes the vertebral body to shift, it is referred to as spondylolisthesis.

摘要

Spondylolysis is characterized by a posterior defect in the vertebral body, specifically at the pars interarticularis. Typically, this defect is a consequence of trauma or persistent repetitive loading and hyperextension. When this instability causes the vertebral body to shift, it is referred to as spondylolisthesis.
