The stress fracture of the pars interarticularis occurs on the side opposite to activity. For instance, for a right-handed player, the fracture occurs on the left side of the vertebrae. [5] Pars interarticularis marked with red lines. Spondylolysis has a higher occurrence in the following activities: [5] Baseball; Military service; Tennis ...
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 ...
As a result, Barsa and coauthors showed that the result of fracture fusion reduced after one year but only one patient died of other disease during the follow-up. [8] Hakalo and Wronski (2008) showed the benefits of operative treatment such as using transoral C2-C3 discectomy with plate-cage stabilization or posterior direct pars screw repair ...
Spondylolysis, also known as a pars defect, is a defect or fracture at the pars interarticularis of the vertebral arch. Spinal disc herniation , more commonly called a "slipped disc", is the result of a tear in the outer ring ( anulus fibrosus ) of the intervertebral disc , which lets some of the soft gel-like material, the nucleus pulposus ...
Computed tomography can be helpful in evaluating bony vertebral abnormalities, such as fractures. [38] This can be helpful in determining if the fracture is a new, old, and/or progressing fracture. [38] CT use in spondylolisthesis evaluation is controversial due to high radiation exposure. [39]
Open fracture with adequate soft tissue coverage of a fractured bone despite extensive soft tissue laceration or flaps, or high-energy trauma (gunshot and farm injuries) regardless of the size of the wound [14] [15] IIIB: Open fracture with extensive soft-tissue loss and periosteal stripping and bone damage. Usually associated with massive ...
The petrous part of the temporal bone is pyramid-shaped and is wedged in at the base of the skull between the sphenoid and occipital bones.Directed medially, forward, and a little upward, it presents a base, an apex, three surfaces, and three angles, and houses in its interior the components of the inner ear.
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
