The pain could be diffuse in the lower extremities, involving the L5 and/or L4 roots unilaterally or bilaterally, but generally bilaterally Symptoms decrease with sitting or standing with lumbar flexion and with lying.
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.
• Type 1: Congenital spondylolisthesis An elongation of the pars interarticularis can be seen in congenital spondylolisthesis, in which the pars lesion is due to a congenital anomaly of the L5-S1 facet articulation.
As the slip progresses, the pars elongates in response to the deformity.
This relationship is known as neurogenic intermittent claudication According to Jerrad MD. in the first month after the first symptoms increase the likelihood of the formation of a bony callus. concluded that the formation of a bony unit is not inevitable for a good clinical outcome of therapy.
As it happens a fibrocartilaginous callus can also be sufficient for normal functioning and pain reduction, and can meet the requirements of an athlete.
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.
• 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.
