spondylolisthesis

Spondylolisthesis

The term spondylolisthesis is derived from the combined Greek terms spondylos (vertebra), and listhesis (to slip). The term literally means the “slippage of one vertebra forward in relation to the adjacent vertebra.

Spondylolisthesis is the subluxation of a vertebral body over another in the sagittal plane.

Classification

Five types were classified according to the Wiltse classification system 1):

Degenerative spondylolisthesis.

Isthmic spondylolisthesis.

Traumatic spondylolisthesis

Pathologic spondylolisthesis

Dysplastic spondylolisthesis


see Cervical degenerative spondylolisthesis.

see Thoracic degenerative spondylolisthesis.

see Lumbar degenerative spondylolisthesis.


see High grade spondylolisthesis

Treatment

Surgery is indicated if symptoms are disabling and interfere with work, if the condition is progressive, or if there is a significant neurological deficit. The ideal surgical treatment remains controversial 2).

Lumbar fusion for spondylolisthesis tends to yield more consistent outcomes than fusion for degenerative disk disease and discogenic low back pain.

Types

Posterolateral fusion

posterior lumbar interbody fusion
