Spondylolysis Essay

Decent Essays

A defect in the pars interarticularis of the spine is defined as spondylolysis (Debnath et al., 2009). Spondylolysis is commonly known as a stress or fatigue fracture and it appears to be more frequent in children and adolescents. The first sign of spondylolysis starts with subtle stress reaction within the bone of the posterior arch of the lumbar spine which my develop and lead to a stress fracture. The frequency of this injury in the youthful athletic populace is much higher than the overall public also varies somewhere around 15% and 47% in children athletes. Apparently, repetitive lumbar hyperextension and excessive loading may predispose the youngest sporting population for this type of injury. In addition, genetic inheritance weakness …show more content…

(2009) suggested that stress on the pars interarticularis during infancy, early adulthood may be a reason for the development of dysplasia. Moreover, the ossification during the embryological state may not progress uniformly or there appears to be a transition between dense trabecular bone in the PI and the inferior articulating facet and less dense trabecular bone at the base of the pedicle only in the lower segments. Such abnormalities in tissue density may persist into childhood leading to a potential area of weakness.

Apparently, repeated microtrauma from sheer and compression associated particularly with hyperextension may predispose youth athletes to new acute symptomatic defects of PI. This microtraumas may further be affected by excessive compression and extension or rotation, which is a characteristic of many sports.

Symptoms start with a gradually onset of low back pain and may vary according to age, the type of pars defect nd sporting activities. Pain appear to arise from the spondylolysis ligament that contains neuropeptides which are related to sensory or nociceptive transmission and high density neural tissue. Pain may be associated with disc degeneration nd facet joint degeneration and segmental
