Based on recent studies, it is postulated that the radiology and shape of the facet joints, such as more frontally oriented facet with a wide surface during extension and flexion and higher stresses on the posterior element, is related to the development of these clefts [ 122144 ]. As grading healing progresses, the fracture line disappears with marginal sclerosis. Clinical Features In Contrastive analysis hypothesis slideshare logo to their limited origin, isthmic spondylolysis and spondylolisthesis present a challenging clinical picture.
The signal intensity of the defect is variable: low on T1-weighted images, low to intermediate on T2-weighted images when the defect is composed of fibrous or fibrocartilaginous tissue, and low on both T1- and T2-weighted images when osseous union is noted. Orthopedic testing is invariably vague in establishing the diagnosis, but the stork test should be included in the examination of any patient with suspected spondylolysis. Grades Spondylolisthesis.

Previously reported cases of pedicular clefts in athletes, such as weight lifters, soccer, baseball, and volleyball players, ballet dancers and gymnasts, whose repetitive shearing and rotational forces were loaded to the pedicle, have been documented [ 10 , 43 , 51 ]. The spinous process at L2 is slightly deviated arrow head. CT is believed to be the most useful modality in the evaluation of size and location of the isthmic fracture.

Although it has been contentiously recommended that one not routinely perform oblique views owing to high radiation dose and low diagnostic yield, this is the only view that reliably depicts spondylolysis.

The mechanism of the slippage of the lumbar spine in skeletally immature subjects is still being debated. This is also supported by the high incidence of spondylolisthesis observed in certain ethnic groups and the heredity of spondylolisthesis in some families. The defects of the bilateral pars are demonstrated with surrounding sclerosis, and the margin of both clefts is irregular arrows. If the defect is wider than the amount of slippage, then resorption has occurred at the defect; if it is narrower, then attempted healing has occurred.

Bilateral pars defects at the L4 vertebra allow anterior displacement of the body and pedicles. Occasionally, flexion-extension dynamic studies show motion across the pars defect. Pedicular fractures in patients with degenerative lumbar spondylosis, osteoporosis due to medication with predonisone, and after spinal surgery have also been noted and reported to occur unilaterally and bilaterally [ 41 , 52 , 53 ]. On an oblique film the alignment of the facet joints changes abruptly at the level of slippage. Two adjacent vertebrae, the intervertebral disc, spinal ligaments and facet joints between them constitute a functional spinal unit [ 2 ] Fig.
