The facet joints are formed by the superior and inferior processes of each vertebra. The first cervical vertebra has an inferior articulating surface but, as it does not restrict lateral or posterior translation, is not always considered a proper zygoma [9] (zygoma is Greek for "yoke", i.e. something that restrains movement).
The bone grafts complete their fusion in 4–8 months following the surgery, securing the spine in the correct position. The procedure is also used to treat spinal instability, fractures in the lumbar spine and, severe degenerative disc disease. The process is relatively non-invasive, performed through small incisions and has a high success ...
Clay-shoveler fracture – fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae; Burst fracture – in which a vertebra breaks from a high-energy axial load; Compression fracture – a collapse of a vertebra, often resulting in the form of a wedge-shape due to larger compression ...
The burst fracture is categorized by the "severity of the deformity, the severity of (spinal) canal compromise, the degree of loss of vertebral body height, and the degree of neurologic deficit." [2] Burst fractures are considered more severe than compression fractures because long-term neurological damage can follow. The neurologic deficits ...
Bilateral C2 pars fractures are known as a variant of the hangman's fracture. On an anterior oblique radiograph of the lumbar spine , the pars is the neck of the imaginary Scottie dog; the Scottie dog's eye is the pedicle, [ 3 ] its hindlegs the spinous process, its nose the transverse process, its ear the superior articular facet and its ...
A tear in the disc ring may result in the release of chemicals causing inflammation, which can result in severe pain even in the absence of nerve root compression. Disc herniation is normally a further development of a previously existing disc protrusion , in which the outermost layers of the annulus fibrosus are still intact, but can bulge ...
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high-dose steroids. [1] The condition may also occur without any clear reason. [1] The most commonly affected bone is the femur (thigh bone). [1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1]
