Define Congenital spondylolisthesis
Dysplastic (congenital) spondylolisthesis results from a congenital defect at the L5-S1 articulation
Spondylolisthesis Treatment, Surgery & Symptoms
There may be no objective signs in Spondylolysis, or in first or second degree Spondylolisthesis. The finding of Spondylolysis on x-ray in an adult is likely to be incidental, and not the cause of back pain if that pain did not commence in childhood or adolescence. Tightened hamstrings are present in the majority of those who are symptomatic. Tenderness and spasms of the paravertebral muscles may be present at the level of the vertebral defect and surrounding segments. Pain may be induced and increased by certain movements.
Biomechanical factors are significant in the development of spondylolysis leading to spondylolisthesis. Gravitational and postural forces cause the greatest stress at the pars interarticularis. Both lumbar lordosis and rotational forces are also believed to play a role in the development of lytic pars defects and the fatigue of the pars in the young. An association exists between high levels of activity during childhood and the development of pars defects. Genetic factors also play a role.

Dysplastic Spondylolisthesis results from congenital abnormalities of the upper sacral facets or inferior facets of the fifth lumbar vertebra that allow slipping of L5 on S1.
In Spondylolysis, symptoms are often absent. Defects are then discovered only incidentally on x-ray made for other purposes. In Spondylolisthesis, injury may aggravate (permanently worsen) any symptoms, but rarely does a single injury cause symptoms in a person who previously had none. Symptoms generally begin insidiously during the second or third decade as an intermittent dull ache in the lower back, present with increasing frequency during walking and standing. Later, pain may develop in the buttocks and thighs, and still later unilateral sciatica may develop.
The most common symptom of spondylolisthesis is lower back pain
The etiology of spondylolisthesis is multifactorial. A congenital predisposition exists in types 1 and 2, and posture, gravity, rotational forces, and high concentration of stress loading all play parts in the development of the slip.
Several theories on the causes of pain in patients with spondylolytic spondylolisthesis have been proposed. These include isthmic defect, the intervertebral disc, adjacent facet joint and stenotic changes which have been implicated in the causation of back and sciatica syndrome. Histological studies have demonstrated the presence of nociceptive fibres in the pars defect. Communication between the facet capsule and the isthmic defect which appear to occur because of capsular tears. Kirkaldy-Willis has drawn attention to the lateral recess and foraminal stenosis with entrapment of the exiting nerve by the pars interarticularis. Fibrosis around the exiting nerve following laminectomy and fusions in patients with spondylolisthesis provides another source of pain.

The following is a classification of Spondylolisthesis and Spondylolysis according to cause:
Type I. Dysplastic: This type results from congenital abnormalities of the upper sacral facets or inferior facets of the fifth lumbar vertebra that allow slipping of L5 on S1.

There are multiple classification of lumbar and lumbo-sacral spondylolisthesis. As such clinically, in the adults the distinction between isthmic and congenital spondylolisthesis is considered to be theoretical and anatomic (Ref). We have used the term lytic spondylolisthesis in adults who have presented with lytic defect in the pars to distinguish them from patients with attenuated pars interarticularis and patients with degenerative, post surgical, post traumatic, pathological spondylolisthesis and that occurring in patients with widespread or localised bone.

Type II. Isthmic: This type results from a defect in the pars interarticularis that allows forward slipping of L5 on S1. Three types of isthmic spondylolistheses are recognized:

Neurologic signs often correlate with the degree of slippage and involve motor, sensory, and reflex changes corresponding to nerve-root impingement (usually S1). Progression of listhesis in these young adults usually occurs in the setting of bilateral pars defects and can be associated with the following physical findings:

Type I. Dysplastic: This type results from congenital abnormalities of the upper sacral facets or inferior facets of the fifth lumbar vertebra that allow slipping of L5 on S1. There is no pars interarticularis defect in this type. The sacrum is not strong enough to withstand the weight and stress. Thus, the pars and inferior facets of L5 are deformed. If the pars elongates, it is impossible to differentiate it by x-ray from the isthmic (type II b) Spondylolisthesis. If the pars separates, it becomes impossible to differentiate it by x-ray from the isthmic lytic (type II a) Spondylolisthesis. This type is also associated with sacral and neural arch deficiencies. It has a familial tendency.
