Spondylolisthesis of l5 on s1 - Grade2 Spondylolisthesis of L5/S1
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.
So why does spondylolisthesis affect the L5-S1 joint in particular?
Spondylolisthesis has been classified into grades I, II, III, IV and V depending on the severity of the displacement of the vertebra above on the vertebra below. In severe cases involving the lumbar spine, cauda equina syndrome can occur.
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.

The clinical examination provides information about the location of the pain, muscle spasm, lumbar spine range of motion, hamstring muscle tightness, muscle strength in the legs, reflexes, and sensation in the legs.

Question: Hi Chad, I recently purchased from Amazon, and think its a very well written book. I love the plans and how they’re laid out in the book. I’ve been strength training for a few years, and have had decent trainers along the way, so I honestly feel like I have form pretty locked down.With that said, I was experimenting with my back arch while doing back squats in June this year, and ended up herniating my L5/S1 disc in my lumbar spine – so completely stupid and a mistake I’ll never make again. I was out for a few months, and did physical therapy for over 2 months. I’m now back in action, and have been cleared to do split squats, single leg squats..basically any squat that is not with both legs. I’m leaning on the cautious side!My question for you, is how can I do the program and work around the 2 legged squat / deadlift exercises? I suppose I could wait a few more months to get started, but your book got me excited to focus again.Thanks,

Most spondylolytic defects and cases of Spondylolisthesis are congenital. The prevalence of Spondylolisthesis in the general population is about 5% and is about equal in men and women. Spondylolysis and Spondylolisthesis most frequently involve L5, although L4 can also be affected and, rarely, more proximal levels.
