“…In addition, sacralisation of L5 is 4 times more common in degenerative spondylolisthesis population. This suggests that a relatively immobile L5/S1 articulation tends to predispose L4/5 to added stress [5]. However, such anatomic anomalies are not seen in our case.…”

“…The body-weight transmits a forward and downward vector force to the L5 level, but this force is resisted by the soft tissues and the posterior articulations. When the facet joints are in the sagittal plane there is relatively less bony resistance to anterior shear force compare to joints that are in oblique or coronal orientation [5]. Our case showed a sagittal facet joint orientation at the level L3-L4 and L4-L5, 38.5˚ and 26.5˚ respectively.…”

Abstract:Introduction: Lumbar degenerative spondylolisthesis is a major cause of impaired quality of life and diminished functional capacity in the elderly. Degenerative spondylolisthesis often involves only one or two level and tend to present with one or two level spinal canal stenosis. Case Report: The authors describe an unusual case of degenerative spondylolisthesis involving 3 levels of the lumbar spine from L2 to L5. The patient was a 58 year old woman who suffered chronic back pain and neurogenic claudication. Plain radiography revealed grade I degenerative spondylolisthesis at L2-L3, L3-L4 and L4-L5. Elevated pedicle-facet joint angles and W-type facet joints at the lumbar spine was observed. Magnetic resonance imaging showed L2-S1 spinal cord compression at the lumbar spine. Patient underwent L2-S1 decompression laminectomy and posterior lateral fusion of L2-S1 with posterior instrumentation and bone grafting. Symptoms improved significantly at 4 months follow-up. Conclusion: Thorough evaluation for multilevel segmental involvement in degenerative spondylolisthesis is important because of the frequency of severe symptomatic spinal stenosis or foraminal encroachment. Good surgical outcome can be expected from decompression and stabilization. The pathogenesis of multi-level lumbar degenerative spondylolisthesis can be complex and heterogeneous.

“…Zygapophyseal degeneration can also produce retrolisthesis (posterior slippage). Based on a study of 57 cases (Rothman et al, 1985), however, the pattern of degenerative retrolisthesis is very different. Males are affected more than females (60% to 40%), and the vertebral level involved tends to be higher, with L3-4 accounting for 33% of cases and L4-5 only 27%.…”

“…However, zygapophyseal remodeling was observable in less than 18% of cases, while disc involvement was common. This suggests that retrolisthesis may be more a manifestation of disc degeneration and narrowing than joint degeneration (Rothman et al, 1985). Since this is basically a phenomenon of soft tissue, its identification in archaeological skeletons would present a challenge.…”

Spondylolysis refers to a separation in a vertebral arch between the body and the spinous process. Most spondylolysis seen in humans occurs in the lower lumbar region and is due to stress (fatigue) fracturing, usually through the isthmus between the superior and inferior articular processes. Referred to here as “typical” spondylolysis, it is related to erect posture and bipedal locomotion, and, as such, it is a uniquely hominid condition. It develops only after a child has begun to walk, and a developing lesion may heal or progress to complete separation. Seen more often in males than females, frequencies among populations vary widely. Certain activities have been suggested to put individuals performing them at greater risk to develop the condition. Although often approached as a pathological condition requiring corrective treatment, spondylolysis usually produces relatively mild symptoms if any at all, and may even provide the advantages of greater lower back flexibility. Complete bilateral spondylolysis separates the inferior articular processes from the body, thus allowing the body to slip forward relative to the vertebra below (spondylolisthesis). Another form of the condition, referred to as degenerative spondylolisthesis, allows a slow forward migration of one vertebra over another due to osteoarthritic remodeling of the posterior vertebral joints without any spondylolysis. © 1996 Wiley‐Liss, Inc.

“…4 However, in a comparative study of facet orientation in younger and older patients, Love et al concluded that the sagittal orientation of the facet angle is a result of arthritic remodeling in the older age group, and not a primary cause of degenerative spondylolisthesis. In a review of 150 cases, Rothman et al 15 reported that forward subluxation is primarily a disease of the posterior joints and is found most commonly at L4 -L5, whereas retrolisthesis is a primary disorder of the disc space and is noted more commonly at L3-L4. The slip was almost always referred to as anterolisthesis.…”

Decompression primarily relieves radicular symptoms and neurogenic claudication whereas fusion primarily relieves back pain by elimination of instability. The goals for instrumentation are to promote fusion and to correct deformity. Fusion has a better long-term outcome than decompression alone. There is evidence that instrumentation improves fusion rate but does not improve clinical outcome in a relatively short-term follow-up. However, outcome of pseudarthrosis cases deteriorates over time and solid fusion produces better long-term outcome. The benefit of instrumentation comes with a price of higher postoperative morbidity and complication rate. Bone morphogenetic proteins are being tried to increase the rate of fusion, without increasing the complication rate, but the cost is prohibitive. More recently, dynamic stabilization with instrumentation but without fusion has been introduced as an alternative treatment. The current trends of surgical treatment and controversies are discussed.
