Stability of the lumbar spine is necessary during functional activities. įigure 1: Aspects of the Lumbar vertebrae The pedicles are the junction between the vertebral body and the neural arch. The processes spinous are thick and broad, and are dorsally and caudally orientated. Due to the weight-bearing function of the lumbar spine, the lumbar vertebral bodies are larger than the other vertebral bodies of the spine. The lumbar vertebrae consist of various parts, in particular the vertebral body, the posterior elements (one process spinous and two processes transversus) and two pedicles. Those five vertebrae are the largest of the spine and increase in size from superior to inferior. The lumbar spine, consisting of 5 separated vertebrae, is located between the thoracic spine and the sacrum. In some cases, the syndrome can also evoke neuromuscular damage. Kissing Spine has numerous consequences such as the formation of hypertrophic spinous processes, which can lead to mechanical back pain in combination with degenerative disc disease. ,, , Kissing Spine mainly affects the lumbar area of the spine, with L4-L5 being the most frequently affected level, but it has also been reported in the cervical spine. ![]() It is described as a condition where adjoining lumbar spinous processes become closely approximated to one another, resulting in the formation of a new joint between them. This syndrome was first diagnosed by Baastrup in 1933. 4 Characteristics/Clinical Presentationĭefinition/Description īaastrup’s Disease, generally known as Kissing Spine, is characterised by degenerative changes of both the spinous processes and interspinous soft tissues of two neighbouring vertebrae.
