These views may demonstrate a pars interarticularis abnormality, which is depicted as a defect in the collar of the ‘‘Scotty dog.’’ Radiographic evaluation should not be an isolated clinical examination.
• It is the opinion of the work group that in adult patients with history and physical examination findings consistent with isthmic spondylolisthesis, standing plain radiographs, with or without oblique views or dynamic radiographs, be considered as the most appropriate, non-invasive test to confirm the presence of isthmic spondylolisthesis.
• In the absence of a reliable diagnosis on plain radiographs, computed tomography scan is considered the most reliable diagnostic test to diagnose a defect of the pars interarticularis.
This, in turn, leads to one of the most obvious manifestations of lumbar instability. analysed the correlation between disc degeneration and the age, duration and severity of clinical symptoms and grade of vertebral slip.
This slippage can occur in 2 directions: most commonly in anterior translation, called anterolisthesis, or a backward translation, called retrolisthesis. The disc degeneration on subsegmental level was significantly related to age and duration of clinical symptoms, although it was not related to the severity of clinical symptoms or the grade of vertebral slip There are different classification systems regarding the etiology, terminology, subtypes of spondylolysis and spondylolisthesis, and treatment. Wiltse Classification: It is one of the most commonly used classification systems to convey the etiology of spondylolisthesis.
Degenerative changes to both the facet joints and the intervertebral disk cause the slip.
Sagittal orientation of the facet joints and facet tropism also have been related to the development of degenerative spondylolisthesis.
There is insufficient evidence to make a recommendation for or against the use of palpation in the physical exam diagnosis of adult patients with isthmic spondylolisthesis.
Grade of Recommendation: I (Insufficient Evidence) 2.
This pathology involves a fractured pars interarticularis of the lumbar vertebrae, also called the isthmus.
This affects the supporting structural integrity of the vertebrae, which could lead to slippage of the corpus of the vertebrae, called spondylolysthesis.
