SPONDYLOLYTIC SPONDYLOLISTHESIS
SPONDYLOLYTIC SPONDYLOLISTHESIS
Spondylolytic Spondylolisthesis is a condition in which bilateral fracture (stress fractures) of the pars interarticularis of the vertebra occurs.
Pars interarticularis is the portion of the laminae that is between the superior and inferior articular processes of a vertebra. It is subjected to bending forces that are transmitted from lamina to the pedicles.
In this condition, the posterior elements which include the laminae, the articular processes, the spinous process and the transverse processes get completely separated from the neural arch and the vertebral body.
As a result, the vertebral body begins to slip forward on the vertebra below. This slipping forward of the vertebra causes alteration in its location and creates excessive stress on supporting ligaments and joints which in turn causes narrowing of the posterior joint space. When the posterior joint space is narrowed, there is a compression on spinal nerves, the spinal cord or the cauda equina. It occurs most frequently at the L5/S1 because of the angulation of the segment and the anterior shear forces that exist there.
The impingement of the nerves may cause lower back pain.
The pain sensitive structures are:
1. Anterior and posterior longitudinal ligaments
2. Interspinous ligaments
3. Spinal nerves
4. Dura mater
5. Vertebral bodies
6. Zygapophyseal joint capsules
7. Synovial linings
8. Muscles
Symptoms of Spondylolitic Spondylolesthesis are:
Pain areas: in the legs, thighs and buttocks that worsens with standing or lower back
Also common: hamstring tightness, stiffness, or tenderness
Diagnosis:
Can be done through
1. X-ray
2. MRI
3. CT scan
Treatment:
1.Devices
Back brace
2. Surgery
Facetectomy
3. Medications
Analgesic and Nonsteroidal anti-inflammatory drug
4. Medical procedure
Epidural steroid injection
5. Self-care
Physical exercise

6.Therapies
Stretching
