Severity of spondylolisthesis is classified by percentage of slip. Surgical fixation is indicated in the presence of neurologic injury or segmental instability and should involve instrumented fusion across both levels. Answer 1 anterior stabilization is an option, but must involve both the levels above and below (c4-6) for this separation type fracture.
Separation type fractures have 2 fracture lines involving the lamina and pedicle, leading to separation of the articular mass from the vertebral body. This compromises the stability of the inferior facet (of the vertebra above) and the superior facet (of the vertebra below), leaving the entire lateral mass free from the adjacent vertebral segment, yielding 2 levels of instability. Comminution type fractures have multiple fracture lines, including lateral wedging and coronal plane deformity.
Split type fractures have a vertical fracture line in the coronal plane, with separation of the lateral mass in the ap plane and upward migration of the superior articular process of the vertebra below. Figure b shows floating left lateral mass (fracture lines through lamina and pedicle). Affected birds are unable to stand normally and may be completely paralyzed. .

The moving forwards of a vertebra relative to the one under it, most commonly of the 5th lumbar vertebra over the top of the ) of the bony arch that bears the facets by which the vertebrae articulate together. The condition may also affect vertebrae in the neck. This compromises the stability of the inferior facet (of the vertebra above) and the superior facet (of the vertebra below), leaving the entire lateral mass free from the adjacent vertebral segment, yielding 2 levels of instability.
Fracture separations of the lateral mass are not well seen on plain radiographs. They found that deformity (mean translation 5 mm and angulation 7 deg) occurred more commonly at the level below (80) than the level above (20). Figure b shows floating left lateral mass (fracture lines through lamina and pedicle).
This is best treated with posterior two-level fusion involving both the level above and the level below. See also orthopedics the forward slippage of a lumbar vertebra on the vertebra inferior thereto, which usually involves lumbar vertebra, most often at the level between the 5 lumbar vertebra, stress fractures, traumatic fractures, bone diseases it may be associated with and produce lordosis clinical low back pain and pain in thighs and buttocks, stiffness, muscle tightness, tenderness in slipped area, paresthesias, sciatica due to nerve root compression forward displacement of a vertebral body with respect to the vertebral body immediately below it, due to congenital anomaly, degenerative change, or trauma.
