(spon'di-lō-lis-thē'sis), [MIM*184200]

spondylolisthesis

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 5th lumbar vertebra and the 1st sacral vertebra; ranges from mild to severe Etiology Congenital defect in 5th 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

an·te·ro·lis·the·sis

(an'tĕr-ō-lis'thĕ-sis)
Forward displacement of a vertebral body with respect to the vertebral body immediately below it, due to congenital anomaly, degenerative change, or trauma.
Synonym(s): spondylolisthesis.
[antero- + G. olisthēsis, a slipping]

spondylolisthesis

The moving forwards of a vertebra relative to the one under it, most commonly of the 5th lumbar vertebra over the top of the SACRUM. This is due to a congenital weakness (SPONDYLOLYSIS) of the bony arch that bears the facets by which the vertebrae articulate together. Spondylolisthesis causes severe backache on standing and leads to nerve pressure effects. The condition may also affect vertebrae in the neck.

The decision to treat the patient with a lumbosacral orthosis can be based on several variables: the presence of a stress fracture or a true fracture, the presence of a spondylolisthesis, pain control, and patient compliance.
In addition, spondylolisthesis remains a commonly seen association and may represent progression in the underlying pars pathology.
(57) When looking at a subgroup of patients with degenerative spondylolisthesis and degenerative scoliosis, no patients in the endoscopic cohort required reoperation within the 1-year follow-up period.
Increased angle of PI was determined as a predisposing factor in the pathogenesis and development of degenerative spondylolisthesis, resulting in increased PI, increased SS, and increased LL (4,8,9).
Many short-term follow-up studies have shown positive outcomes for lumbar spinal stenosis with or without spondylolisthesis;[6],[7] however, long-term studies are limited.[8] Moreover, some recently published studies have reported contradictory results, indicating that Dynesys may not provide a significant advantage for outcomes.[9],[10] This retrospective study presented a 6.6-year follow-up (range, 72-96 months) study of lumbar spinal stenosis treated with decompression and Dynesys stabilization.
