Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
The former are wider apart than the latter since in the articulated column, the inferior articular processes are embraced by the superior processes of the subjacent vertebra. [1] The transverse processes are long and slender. They are horizontal in the upper three lumbar vertebrae and incline a little upward in the lower two.
Transitional vertebrae have the characteristics of two types of vertebra. The condition usually involves the vertebral arch or transverse processes. It occurs at the cervicothoracic, thoracolumbar, or lumbosacral junction. For instance, the transverse process of the last cervical vertebra may resemble a rib.
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 ...
There are seven processes projecting from the vertebra: one spinous process; two transverse processes; four articular processes; A major part of a vertebra is a backward extending spinous process (sometimes called the neural spine) which projects centrally. [7] This process points dorsally and caudally from the junction of the laminae. [7]
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 the vertebra, the pars interarticularis is the bony segment between the superior and inferior articular facet joints ...
Nix sustained a transverse process fracture in his back during the first half of a game against the Las Vegas Raiders on Nov. 24. He finished the game and played the following week through pain ...
The posterior quarter of the ala represents the transverse process, and its anterior three-quarters the costal process of the first sacral segment. Each ala also serves as part of the border of the pelvic brim. The alae also form the base of the lumbosacral triangle. The iliolumbar ligament and lumbosacral ligaments are attached to the ala.
