“…However, too limited a decompression can be accompanied by re-growth of bone that affects the long term results. Also total laminectomy at multiple levels may result in instability of the spine [8,12,13] and restriction of movement in long term. Verbiest suggested that narrowing is due to encroachment by the articular process on the spinal cord and the laminectomy alone may not suffice without removal of the medial part of the articular facets [9,15] .…”

Background: With the increasing longevity of population and a continually climbing proportion of middle-aged and elderly persons, the problem of lumbosacral spine is a significant health care issue, causing backache and Neurogenic claudication. Methods: Thirty patients with degenerative lumbar canal stenosis were included in study and wide interlaminar fenestration with or without discectomy was carried out. Patients were followed and analysis of the outcome was done for improvement in pain, neurological improvement and improvement in claudication distance. Results: Diagnosis of degenerative lumbar canal stenosis were made by clinical examination and confirmed by measuring neural canal diameter in MRI. Patients were selected randomly and total 30 patients included in study with mean age of 45.9 year and with mean duration of symptom was 38.67 months. Wide interlaminar fenestration was done at two level (L4-5, L5-S1) in 9 patients and at one level in remaining 21 patients (L4-L5 in 12 and L5-S1 in 9). All the patients improved in terms of back pain, sensory and motor symptoms including neurogenic claudication. Conclusion: At the end of our study we find that Wide Interlaminar fenestration done in degenerative lumbar canal stenosis provides not only full resolution of neurological symptom but also maintains spinal stability at the same time.

“…This is based on the fact that the central canal may be divided into a static and a dynamic segment. The static segment is the area at the level of the pedicles which is narrow only in primary canal stenosis [13] . The dynamic segment at the level of the Ligamentum flavum is narrowed in degenerative secondary canal stenosis.…”

Objectives: To evaluate thoracolumbar fractures and the complications such as adjacent disc degeneration (ADD) and post-traumatic deformity. Methods: We evaluated 32 patients divided into two equal groups, 16 in the case group (removal of the synthesis material) and 16 in the control group (not submitted to removal of the synthesis material) in order to verify if there was difference between the incidence of these complications. Results: There were no statistically significant differences between the groups regarding the progression of the ADD and the post-traumatic deformity, but both progressed during the 2-year follow-up. Conclusion: It was concluded that the removal of the synthesis material was not effective in preventing these complications after surgical fractures of the thoracolumbar spine.Keywords: Intervertebral disc degeneration; Fractures; Spine. RESUMO

“…This can lead to fracture of the facets, trauma of neural elements, disc disruption, or spondylolisthesis [19,[55][56][57]. Four general causes of post-surgical spondylolisthesis are laminectomy with partial or complete facetectomy for spinal stenosis, discectomy and partial facetectomy, recurrent disc herniation after discectomy, or fusion at an adjacent level or coextensive with a previous fusion as part of a pseudoarthrosis [56].…”

“…Biomechanically, the aims of minimally-invasive procedures are that the decreased amount of tissue removal will reduce the impact on the normal motion segment's stability and function, and reduce the amount of adjacent level segment degeneration. The biomechanical evaluation of the role of facetectomies and traditional laminectomies have been studied before [15][16][17][18][19][20][21][22][23][24], but there have been few biomechanical studies on MI facetectomies [25].…”
