Dysplastic anterolisthesis (also called type 1) results from congenital abnormalities of the upper sacral facets or inferior facets of the fifth lumbar vertebra, and accounts for 14% to 21% of all anterolisthesis. [10] Isthmic anterolisthesis (also called type 2) is caused by a defect in the pars interarticularis (spondylolysis) but it can also ...
The exam is based on neurological responses, touch and pinprick sensations tested in each dermatome, and strength of the muscles that control key motions on both sides of the body. [7] Muscle strength is scored on a scale of 0–5 according to the adjacent table, and sensation is graded on a scale of 0–2: 0 is no sensation, 1 is altered or ...
Retrolisthesis can be classified as a form of spondylolisthesis, since spondylolisthesis is often defined in the literature as displacement in any direction. [1] [2] Yet, medical dictionaries usually define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum).
Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by abnormal calcification/bone formation (hyperostosis) of the soft tissues surrounding the joints of the spine, and also of the peripheral or appendicular skeleton. [1] In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the ...
The aim of deep abdominal co-contraction exercises is to train muscles surrounding the lumbar spine which provide stability of the spine. Spondylolysis results in a spinal instability and disrupts patterns of co-recruitment between muscle synergies. Specifically, local muscles that attach directly to the spine are affected. The lumbar ...
Gaenslen's test, also known as Gaenslen's maneuver, is a medical test used to detect musculoskeletal abnormalities and primary-chronic inflammation of the lumbar vertebrae and sacroiliac joint. [1] This test is often used to test for spondyloarthritis , sciatica , or other forms of rheumatism , and is often performed during checkup visits in ...
It represents <1% of all cervical spine injuries. [1] Several subtypes of atlanto-occipital dislocation are known. One suggested categorization scheme includes anterior, vertical and posterior of the head relative to the spine. Other variants with lateral or rotatory displacement have been described, as well as mixed types.
