Learn about the types and symptoms of spondylolisthesis

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.

High-grade traumatic C7-T1 spondylolisthesis without neurological deficits is very rare.

The mechanism of traumatic lumbar spondylolisthesis is complex and controversial. Some authors supported that hyperextension stress, hyperflexion and compression stress, or tangential force may be responsible for the occurrence of the trauma. It is challenging to propose an exact mechanism when the injury is complicated and severe. In our opinion, as the case had fracture of facet joints, the vectors of compression or axial translation may be the cause of the injury. Subsequently, we suggest the main factor is combination of tangential force and compression force.

High-grade Traumatic Spondylolisthesis of C7 on T1 …

The lytic (subtype a) results from the separation or dissolution of the pars. The incidence of this type of Spondylolisthesis increases from less than 1 percent in children 5 years of age to 4.5 percent in children 7 years of age. The remaining 0.8 to 1 percent increase occurs between the ages of 11 to 16 years, presumably because of stress fractures caused by athletic activity. Extension movements of the spine, with lateral flexion, can increase the shearing stress at the pars interarticularis and result in Spondylolysis.

Although this subtype has a strong hereditary tendency, it makes up only half of the dysplastic group. The elongated pars (subtype b) is believed to result from micro fractures that heal with an elongated pars rather than from a lytic lesion. Acute pars fractures (subtype c) always result from significant trauma; these are rare and most frequently occur with Spondylolysis rather than with Spondylolisthesis.

Traumatic lumbar spondylolisthesis is uncommon lesion usually secondary to violent trauma. Among these injuries there were characteristic concomitant transverse processes fracture- of adjacent segments and according to the points of Herron and Roche PH the presence of transverse process fracture must result in the suspicion of associated traumatic lesions of the lumbosacral joint. Our case also suffered from fractures of transverse processes, which support the above viewpoint. However, the transverse process fracture is not the necessary sign associated with this kind of injury.,

Traumatic spondylolisthesis by Lori Valliere - issuu

Five types of spondylolisthesis are reported in literatures including dysplastic, isthmic, degenerative, traumatic and pathologic spondylolisthesis. Traumatic spondylolisthesis is usually accompanied by a fracture of the posterior elements, which result in instability and listhesis.
