The relationship between spondylosis and spondylolisthesis.
Patients with spondylolysis do not usually have any symptoms and may not even be aware that they have this condition. When symptoms do occur, they may include pain in the lower back, which is usually worse with physical activity. Symptoms are most common after the teenage growth spurt, which is usually around age 15 or 16.
Many patients with spondylolysis are asymptomatic. Of those with symptoms, approximately one-quarter are associated with spondylolisthesis.3 Pain is usually limited to the low back. If the pain radiates, it is usually to the buttocks or the back of the thigh and is often from hamstring tightness rather than lumbar radiculopathy. With associated higher grade spondylolisthesis, however, radiculopathy becomes more common due to associated foraminal stenosis.
Are Spondylosis and Spondylitis the Same Thing?

Type II: Isthmic. Caused by a defect in the pars interarticularis that may be a fatigue fracture, an acute fracture, or an intact but elongated pars.
What is the difference between spondylosis and spondolysis?
Spondylolysis refers to an osseous defect within the posterior neural arch, most commonly within the pars interarticularis, an isthmus of bone located between the superior and inferior articular processes. Spondylolysis most commonly affects the L5 level (in 85 ” 95% of cases) with the majority of the remaining cases occurring at L4 (5 ” 15% of cases).1 While the exact etiology of spondylolysis is unknown, it is generally believed to represent a stress fracture caused by repetitive loading,2 although there are hereditary and genetic contributing factors.
What is the difference between spondylosis and spondolysis
Imaging evaluation of a patient with low back pain typically begins with a series of lumbar spine radiographs. Spondylolysis is usually evident on lateral radiographs, although oblique projections may be useful. On frontal projections, fragmentation of the lamina may be identified.4 If spondylolisthesis is present, it should be graded according to the Myerding system,5 with grade I indicating anterior subluxation of less than 25%; grade II, 25% to 50%; grade III, 50% to 75%; and grade IV, 75% to 100%.

Spondylolisthesis is readily identified on the midline sagital images. However, as most cases of spondyolysis have normal lumbar vertebral alignment, other findings must be utilized to detect the pars defects. In addition to demonstrating cortical disruption of the pars (A,B), several ancillary findings have been described that may aid in the diagnosis of lumbar spondylolysis.6,7,8 These include a widened anteroposterior diameter of the spinal canal on sagittal images, reactive marrow changes in the posterior elements, and abnormal wedging of the posterior aspect of the vertebral body.
