    • 3. OVERVIEW (definition) The word spondylolisthesis is derived from the Greek words spondylo , meaning spine, .and listhesis , meaning to slip or slide • It is a descriptive term referring to slippage (usually forward) of a vertebra and the spine above it relative to the vertebra below it • It lead to a deformity of the spine as well as a narrowing of the spinal canal (central spinal stenosis) or compression of the exiting nerve roots (foraminal stenosis).

    • 8. PATHOPHYSIOLOGY and TYPES Free Powerpoint Templates Page 8
    • 9. PATHOPHYSIOLOGY • Spondylolisthesis occurs when there’s bilateral defects in the vertebral pars intrarticulariss which permit the vertebral body to slip anteriorly. Usually occurs at level (L5,S1) • Spondylolysis is the most common cause for spondylolisthesis. It’s a unilateral or bilateral defect in the vertebral pars interarticularis result from Free Powerpoint Templates stress fracture. Page 9
    • 10. • spondylolysis typically is acquired as the bone "fatigues" from recurrent microtrauma during excessive lumbar hyperextension or repeated lumbar flexion and extension. • rebeated Hyperflextion and extension of the joints are more common in athletes. • (diving, weight lifting, wrestling and football) Free Powerpoint Templates Page 10
    • 11. • Spondylolysis progresses to spondylolisthesis in approximately 15% of cases. Progression to spondylolisthesis is correlated with persistent pain and lack of healing. Free Powerpoint Templates Page 11
    • 12. TYPES ( according to etiology ) It can be classified into 6 distinct categories as the following ( developed by Wiltse, Macnab, and Newman ): Type I: Congenital spondylolisthesis Type II: Isthmic spondylolisthesis Type III: Degenerative spondylolisthesis Type IV: Traumatic spondylolisthesis Type V: Pathologic spondylolisthesis Type VI Free Powerpoint Templates : Postsurgical Page 12
    • 13. Type I: Congenital spondylolisthesis • characterized by presence of dysplastic sacral facet joints allowing forward translation of one vertebra relative to another. Type II: Isthmic spondylolisthesis • Caused by the development of a stress fracture of the pars interarticularis. • It is also further divided into 3 subtypes : Type IIA , type IIB and type IIC . Type III: Degenerative spondylolisthesis It is commonly caused by intersegmental instability producedTemplates arthropathy. by facet Free Powerpoint Page 13
    • 14. Type IV: Traumatic spondylolisthesis Caused by fracture or dislocation of the lumbar spine, not involving the pars Type V: Pathologic spondylolisthesis. Caused by malignancy, infection, or other types of abnormal bone Type VI : Postsurgical (iatrogenic) Free Powerpoint Templates Page 14
    • 15. EPIDEMIOLOGY - Generally - Mortality/Morbidity - Race - Sex - Age Free Powerpoint Templates Page 15
    • 16. Generally •Approximately 82% of cases of isthmic spondylolisthesis occur at L5-S1. Another 11.3% occur at L4-L5. • Heavy Athletic activities requiring predispose some athletes to developing pars defects. • Degenerative spondylolisthesis occurs more frequently with increasing age. • The L4-L5 interspace is affected 6-10 more times than any other level. • Sacralization of L5 is frequently seen with L4-5 degenerative spondylolisthesis . Free Powerpoint Templates Page 16
    • 17. Mortality/Morbidity • Increased mortality is not associated with spondylolisthesis. • The most common morbidity is persistent low back pain or nerve impingement. • Degenerative spondylolisthesis produces characteristic arthritic symptoms that may worsen with age. Free Powerpoint Templates Page 17
    • 18. Race Isthmic spondylolytic defects affect roughly 1.1% of black females. • The most commonly affected group is the white male with an incidence of 6.4%. • Arkara Plains Indians and Aleut people groups have a very high incidence of spondylolytic defects, due to a combination of genetic and environmental factors. Degenerative spondylolisthesis affects black females more commonly than white females( females more affectedFree Powerpoint Templates than males). Page 18
    • 19. Sex • Congenital spondylolisthesis (dysplastic type) occurs with a 2:1 female to male ratio with symptoms beginning around the adolescent growth spurt. These comprise about 14-21% of all cases of spondylolisthesis • Degenerative spondylolisthesis occurs more commonly in females with a 5:1 female to male ratio. The incidence increases after age 40 years. Free Powerpoint Templates Page 19
    • 20. Age •Acute isthmic spondylolysis often occurs during the first and second decades of life. Most cases occur before the patient reaches age 15 years. • Younger patients are at higher risk than older patients for developing progressive spondylolisthesis. •But the risk for progression in adults is rare when the lesion is at L5.. Free Powerpoint Templates Page 20
    • 21. • In contrast, lesions at L4-5 may progress into adulthood because of increased sagittal rotation, shear translation, and axial rotation at this segment •Congenital/dysplastic spondylolisthesis has been documented in children as young as 3.5 months. More commonly, congenital spondylolistheses go undiagnosed until later in life after an individual has been ambulating for quite some time. •Degenerative spondylolisthesis occurs most commonly after age 40 years. Free Powerpoint Templates Page 21
    • 22. CLINICAL PRESENTATION - Symptoms . - Signs . Free Powerpoint Templates Page 22
    • 23. Symptoms 1-The patient is usually asymptomatic. 2- unlikely cause back pain in adults (especially after age 40 y) with no history of symptoms before age 30 years 3-Low back pain is the most common symptom , and it is often exacerbated by motion, The patient may report relief of pain with extended periods of rest. 4- it is associated with numbness and tingling in the legs (L5 or S1 distribution) and leg pain. Free Powerpoint Templates Page 23
    • 24. Signs 1-Tenderness to deep palpation of the spinous process above the slip (typically L4) & causes radicular pain due to palpation. 2- muscle tightness (Tight hamstrings muscle) that is associated with all grades of spondylolisthesis occurs at a rate of 80%. It commonly results in an abnormal gait & inability of the patient to flex the hip with the knees extended. Free Powerpoint Templates Page 24
    • 25. 3- Paraspinal muscle spasm and tenderness are usually present. 4- Limited forward flexion of the trunk is common with reduced straight-leg raising, which may cause pain 5- Postural deformity and a transverse abdominal crease are seen as a result of the pelvis being thrust forward. Free Powerpoint Templates Page 25
    • 26. 6- Patients with degenerative spondylolisthesis (DSPL) are characterized by an increased pelvic tilt (PT) and decreased sacral slope (SS) than the control population, suggesting the presence of a pelvic compensation Free Powerpoint Templates Page 26
    • 27. PHYSICAL EXAMINATION 1-Phalen-Dickson sign: bent-knee, hip-flexed posture with high-grade spondylolisthesis 2-One-legged hyperextension test (stork test): Use To differenation between spondylolysis (+) and spondylolisthesis(-) Free Powerpoint Templates Page 27
    • 28. 1-Phalen-Dickson sign: With increasing slippage, the sacrum becomes relatively more vertical, impairing hip extension and compelling the patient to walk with a knee-flexed, hip-flexed gait Free Powerpoint Templates Page 28

    • 30. DIAGNOSIS In most cases it is not possible to see visible signs of spondylolisthesis by examining a patient. Patients typically have complaints of pain in the back with intermittent pain to the legs. Spondylolisthesis can often cause muscle spasms, or tightness in the hamstrings. Spondylolisthesis is easily identified using plain radiographs. Free Powerpoint Templates Page 30
    • 31. Grades ( Myerding Classification) Free Powerpoint Templates Page 31
    • 32. DIAGNOSTEC TESTS 1- Radiography: lateral view of lumbar spine is especially useful in detection Spondylolisthesis. 2- Computed Tomography: CT SCANNING axial or sagittal image of the lumbar spine can be performed with or without contrast enhancment. 3- Magnetic Resonance Imaging(MRI): has the distinct advantage of imaging of the spine in any plane. Typically, the axial and sagittal planes are used. Free Powerpoint Templates Page 32

    • 53.  Treatment for spondylolisthesis depends on several factors, including the age and overall health of the person, the extent of the slip, and the severity of the symptoms.  Treatment most often is conservative and more severe spondylolisthesis might require surgery. Free Powerpoint Templates Page 53
    • 54. 1.Conservative treatment o Bed rest. o Avoidance of activities if there is >25% slippage. o Non-steroidal anti-inflammatory drug (NSAID). o Epidural steroid injections(ESI) Generally, an ESI is given only when other treatments aren't working. o A brace or back support might be used to help stabilize the lower back and reduce pain. Free Powerpoint Templates Page 54
    • 55. o Physical therapy: Stabilization exercises are the mainstay of treatment. These exercises strengthen the abdominal and/or back muscles, minimizing bony movement of the spine. These measures only provide temporary relief. Free Powerpoint Templates Page 55
    • 56. 2. Surgical treatment  Surgery might be necessary if the vertebra continues to slip or if the pain is not relieved by conservative treatment and begins to interfere with daily activities.  The main goals of surgery for spondylolisthesis are: 1) to relieve the pain associated with an irritated nerve, 2) to stabilize the spine where the vertebra has slipped out of place, 3) and toFree Powerpoint Templates ability to function. increase the person’s Page 56
    • 57. The main types of surgical treatmen for spondylolisthesis include: 1) laminectomy (decompression) 2) Fusion Free Powerpoint Templates Page 57
    • 58. 1. Laminectomy  When the vertebra slips forward, the nearby nerves that exit the spine can become pinched or irritated.  In addition, the size of the spinal canal in the problem area shrinks, placing pressure on the nerves inside the canal. The goal is remove the lamina and release pressure on the nerves . Free Powerpoint Templates Page 58
    • 59. Types of laminectomy : A. traditional open lumbar laminectomy :  the two laminae and spinous process of a vertebra are removed to relieve excess pressure on the spinal nerves in the spine. B.METRx Minimally Invasive Hemilaminectomy:  It involves removing part of one of the two laiminae on a vertebra to relieve excess pressure on the spinal nerve(s) in the lumbar spine. Free Powerpoint Templates Page 59
    • 60. 2. Fusion  A spinal fusion is normally done immediately after laminectomy for spondylolisthesis.  It is designed to fuse the two vertebrae into one bone and stop the slippage from worsening.  The fusion is used to lock the vertebrae in place and stop movement between the vertebrae. • Types : A. Traditional Fusion B. Minimally invasive surgical spine fusion Free Powerpoint Templates Page 60
    • 61. A. Traditional Fusion  The vertebrae are affixed to one another using surgical instrumentation.  Bone graft is then placed between the vertebrae allowing them to "fuse" together over time.  This stabilizes the painful joint segment and relieves pressure from the painful spinal nerves Examples : 1. Postero-lateral fusion (PLF) 2. Posterior Lumbar Interbody Fusion(PLIF) Free Powerpoint Templates Page 61
    • 62. 1. posterolateral fusion (PLF)  posterolateral fusion is the grandfather of fusion technique as it was developed just over 100 years ago.  In a posterior approach to lumbar fusion, the surgeon makes an incision down the middle of the lower back.  One of the criticisms of PLF is that it involves an extensive dissection (the stripping of muscle and fascia off of bone) of the adjacent transverse processes, facet(s) and sometimes lamina.  After the decompression, the surgeon will place graft material along the sides of the vertebrae to stimulate bone growth.  Titanium screws and rods are often used to provide immediate stability to the spine until a Free has been achieved solid fusionPowerpoint Templates . Page 62
    • 63. 2. Posterior Lumbar Interbody Fusion(PLIF):  In this procedure, the problem vertebrae are fused from the anterior (front) and posterior (back).  The surgeon works from the back of the spine and removes the disc between the problem vertebrae.  Bone graft material is inserted from the back of the spine into the space between the two vertebrae where the disc was removed (the interbody space)  Transpedicular instrumentation is attached to stabilize the motion segment while fusion occurs. Free Powerpoint Templates Page 63
    • 64. B. Minimally invasive surgical spine fusion It allows the surgeon to make smaller incisions in the skin and avoid large muscle retraction. • Transforaminal Lumbar Interbody Fuision (TLIF): o It is arguably an important improvement on traditional PLIF, because it minimizes nerve root and thecal sac retraction/damage and necessitates less osseous and soft tissue dissection. o This technique approaches the epidural space from a more posterolateral direction, taking out the facets on one side and only part of the lamina. o The bony endplates are scraped until rough and the space is filled with a plastic or metal cage and bone chipes to achieve a fusion between the vertebral bodies.
