Translations

Spondylolisthesis

spondylolisthesis

[¦span·də·lō‚lis′thē·səs] (medicine) Forward displacement of a vertebra upon the one below as a result of a bilateral defect in the vertebral arch, or erosion of the articular surface of the posterior facets due to degenerative joint disease.

Spondylolisthesis

the forward displacement of the spine in man as a result of degenerative changes in an intervertebral disk or spondylolysis (congenital aplasia of a vertebral arch). The displacement of the fifth lumbar vertebra over the sacrum is the most common form of spondylolisthesis. The disease develops slowly over several years; however, it may sometimes appear suddenly after a trauma. Its development is promoted by other diseases of the spine, including spondylosis, by heavy physical labor, and by an increase in body weight. The disease is manifested by pain and limited mobility in the corresponding segment of the spine. Roentgenologic examination is important in diagnosing spondylolisthesis. Treatment is complex and includes special work arrangements, kinesitherapy, and the use of corsets that relieve strain. Osteoplasty is performed if vertebral displacement is pronounced.

spondylolisthesis

[spon″dĭ-lo-lis-the´sis] forward displacement of a vertebra over a lower segment due to a congenital defect or fracture in the pars interarticularis, usually of the fifth lumbar over the sacrum, or of the fourth lumbar over the fifth. adj., adj spondylolisthet´ic.

spon·dy·lo·lis·the·sis

(spon'di-lō-lis-thē'sis), [MIM*184200] Forward movement of the body of one of the lower lumbar vertebrae on the vertebra below it, or on the sacrum. Synonym(s): spondyloptosis [spondylo- + G. olisthēsis, a slipping and falling]

spondylolisthesis

(spŏn′dl-ō-lĭs-thē′sĭs)n. Forward displacement of one of the lower lumbar vertebrae over the vertebra below it or on the sacrum.

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