When you have spinal fusion surgery it is done by inserting pieces of bone between your vertebrae. These pieces of bones are either gotten from an external source or from the patient themselves. Before the surgeon can use your bones you will have to be found fit in order to provide the bo...
This most commonly occurs at the lumbosacral junction with L5 slipping over S1, but it can occur at higher levels as well. It is classified based on etiology into 5 types: dysplastic, defect in pars inter-articularis, degenerative, traumatic, and pathologic. The most common grading system for...
Amultilevel spinal fusioninvolves fusing two or more levels of the spine, such as theL4-L5andL5-S1 spinal segments. Multilevel fusions considerably limit the normal motion in the lower back and place more stress across the remaining mobile joints. Fusing 3 or more levels of the spine is rar...
Central stenosis arises from anterior ligamentum flavum hypertrophy compounded by posterior disk bulging. This condition is more prevalent at the L4 to L5 level than other spinal segments. Meanwhile, lateral recess stenosis results from facet arthropathy and osteophyte formation, compressing the nerve befo...
strength (ATLIS) device measured strength over time in the treated and untreated leg for three muscle groups, knee extensors (L2–L4 myotomes), ankle dorsiflexors (L4–L5 myotome) and knee flexors (S1 myotome). Percent of predicted normal strength of each muscle was averaged for a total...

The lumbar enlargement of the spinal cord (L4–L5) was the dissected, and then the dorsal quadrants were removed and homogenized in 25 mM Tris-HCl, 150 mM NaCl, 1% NP-40, 1% sodium deoxycholate, and 0.1% SDS supplemented with a complete protease inhibitor mixture (Roche, Upper ...
