Isthmic anterolisthesis (also called type 2) is caused by a defect in the pars interarticularis (spondylolysis) but it can also be seen with an elongated pars. [ 11 ] [ 12 ] Degenerative anterolisthesis (also called type 3 ) is a disease of the older adult that develops as a result of facet arthritis and joint remodeling.
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).
A significant correlation was found between decreased mobility in motion segment C7-T1 and T1-T2 and increased risk for neck- shoulder pain. [1] [4] Norlander and Nordgren [5] have also shown that several clinical symptoms show relationship to segmental mobility examined with CTR. A significant correlation was found between decreased mobility ...
Grade 5 is given when the ilium (bone) is calcified at a level of 100% and the iliac apophysis is fused to iliac crest; it corresponds to the end of growth. Risser grading is traditionally used to estimating the future growth potential of the adolescent spine, particularly in the setting of spinal scoliosis .

The incidence of spondyloarthritis as a disease entity was recorded in only four investigations, and ranged from 0.48/100,000 in Japan [54] to 62.5/100,000 in Spain. [55] [56] Data on the prevalence of spondyloarthritis were reported from 16 investigations; the results ranged from 0.01% in Japan [54] to 2.5% in Alaska. [57] [56]
The vast majority of spondylolysis occur in the lumbar vertebrae, however it can also be seen in cervical vertebrae. [2] The lumbar vertebra consist of a body, pedicle, lamina, pars interarticularis, transverse process, spinous process and superior and inferior articular facets, which form joints that link the vertebrae together. When examining ...
A joint space of between 1.5 and 4 mm is regarded as normal. [15] Ankle osteoarthritis. For the ankle, the Kellgren–Lawrence scale, as described for the hip, has been recommended. [16] The distances between the bones in the ankle are normally as follows: [17] Talus - medial malleolus: 1.70 ± 0.13 mm; Talus - tibial plafond: 2.04 ± 0.29 mm
