Type IV – It is called as Traumatic spondylolisthesis, caused due to acute fracture of the posterior elements Type V – It is Pathologic spondylolisthesis caused by spinal tumours or other pathological conditions. This type of spondylolisthesis usually occurs at L4-L5 region of the spine. Type III – It is Degenerative spondylolisthesis, commonly caused by ageing and disc degeneration. Type II – It is also known as Isthmic spondylolisthesis, generally occurs as a result of abnormal wear on the vertebrae from repetitive stress.

Type I – It is also called as Dysplastic (or Congenital) spondylolisthesis, often caused by birth defects.

Spondylolisthesis – Types & Grades Spondylolisthesis is classified into six types. Hence, it is vulnerable to traumatic injuries, degeneration, disc herniation and nerve compression. L5-S1 receives a higher degree of mechanical stress compared to the above portion and also helps in transferring loads from the spine into the pelvis and legs. L5 and S1 are merged by the lumbosacral facet joints along with articular cartilage. L5-S1 is the point of transition between the lumbar spine and sacral spine in the lower back. Overview of L5-S1 Have you heard of L5-S1 and wondering what is it about? L5-S1 is the lumbosacral junction. In simple words, when the defect weakens the bones to an extent that it cannot maintain its alignment in the spine and starts shifting or slipping out of place. Whereas in spondylolisthesis, the defective pars interarticularis can be only on one side or on both sides.

In simple words, spondylolysis means an underdeveloped or a crack or fracture in one of the vertebrae. a small section of bone joining the facet joints in the back of the spine. Difference between Spondylolysis & Spondylolisthesis Spondylolysis refers to a condition where there is a defect in a portion of the spine called pars interarticularis, i.e. when spondylolysis is left untreated or in case of trauma. It is commonly preceded by spondylolysis, i.e. About 5-6% of males and 2-3% of females suffer from spondylolisthesis. Spondylolisthesis involves the forward slip of superior vertebra over the inferior other relatively, that may cause pain. The word ‘spondylo’ means spine and ‘listhesis’ means slippage. There is no relation between radiological picture and intensity of degenerative changes within the lumbar discs.Spondylolisthesis L5-S1: Symptoms, Causes & Treatment Qi Spine Clinic, 2 years ago What do you mean by Spondylolisthesis L5-S1? Spondylolisthesis refers to the condition where one lumbar vertebrae slips over the other. Also there is no relation between disc degeneration and radiological findings.Ĭlassic x-ray examination presents low value in diagnostics of lumbar disc degeneration and its herniation. We found no relations between other radiological findings (narrow intervertebral space, diminished lordosis, scoliosis) and herniation and its localization within the spinal canal. The statistical analysis revealed the only one relation -between traction osteophytes and herniation classified as disc prolapse (p<0.05). The radiological picture was related to the degeneration of the intervertebral discs. Removed discs were histologically evaluated to determine degeneration symptoms. According to localization, herniation was defined as central, lateral or intermediate. Herniation was classified as protrusion, prolapse or disc sequestration. In each case the x-ray examination of lumbar spine was performed. The study enrolled 187 individuals operated due to lumbar disc herniation. As well, we looked for relation between radiological findings and progression of disc degeneration. The aim of study was to establish relation between radiological findings and herniation type and its localization. The x-ray examination is one of the fundamental diagnostic modalities in patients with low-back-pain.
