Hinged-Dynamic Posterior Device Permits Greater Loads on the Graft and Similar Stability as Compared with Its Equivalent Rigid Device: A Three-Dimensional Finite Element Assessment
Autor: Nicole M. Grosland, K. D. Chesmel, Leon J. Grobler, Regina J. Konz, Han Chang, Vijay K. Goel
Publikováno v: JPO Journal of Prosthetics and Orthotics. 13:17-20
A three-dimensional finite element model was developed to compare the load sharing capabilities of the hinged (or dynamic) versus rigid states of a posterior lumbar spinal fixation device. The objective was to show that a dynamic state of a fixation

Back and Leg Pain in Older Adults: Presentation, Diagnosis, and Treatment
Autor: Leon J. Grobler
Publikováno v: Clinics in Geriatric Medicine. 14:543-576
Back and leg pain in the older population are of diagnostic and therapeutic importance for both primary and tertiary care providers. Careful assessment of the clinical presentation, potential differential diagnosis, and treatment options are essentia

L4–5 Isthmic Spondylolisthesis
Autor: John E. Novotny, Malcolm H. Pope, Leon J. Grobler, John W. Frymoyer, David G. Wilder
Publikováno v: Spine. 19:222-227
The authors have previously reported that the L4-5 isthmic spondylolisthesis lesion often progresses more than the L5-S1 lesion in adult patients. This biomechanical study compares the in vitro stability of the L4-5 isthmic spondylolisthesis lesion c

Publikováno v: Spine. 18:1483-1490
Thirty-three patients underwent decompression without fusion at the L4-5 level for spinal stenosis or degenerative spondylolisthesis. Using preoperative and 1-year postoperative lateral lumbar spine radiographs, the incidence of postoperative spondyl

Paraspinal mapping: Quantified needle electromyography in lumbar radiculopathy
Autor: Diane B. LeBreck, Carol Talley, Leon J. Grobler, Andrew J. Haig
Publikováno v: Muscle & Nerve. 16:477-484
In the diagnosis of low back pain, the presence of a high percentage of false positive findings on radiologic imaging studies has lead to a more definitive role for electrodiagnosis as a confirmatory test. The paraspinal muscles are a crucial part of

Publikováno v: Spine. 18:80-91
This study examined the role of facet joint morphology in the etiology of both degenerative spondylolisthesis and isthmic spondylolysis. To this end, the axial facet joint morphology of the lower lumbar spine in a normal population and in populations
