Background Lumbar laminectomy is a surgical procedure allowing for decompression of
neural structures. A wide laminectomy to adequately decompress neural elements without …

Background. Spine procedures continue to increase significantly. As such, a more precise
understanding of the anatomy, especially the pars interarticularis (PI) is critical. Current data …

Study Design. The assessment of L3 and L4 pars interarticularis thickness and finite element
analysis of stress distribution across L3 and L4 pars interarticularis. Objective. To quantify …

The aim of this study was to measure changes in the cross-sectional area of the spinal canal
and the area of the intervertebral foramen for each pedicle segment before and after the …

Correction of Spinal Sagittal Alignment after Posterior Lumbar Decompression: Does Severity of
Central Canal Stenosis Matter? - PMC Back to Top Skip to main content NIH NLM Logo Access …

Objective To quantitatively assess the impact of supine and standing positions on the
morphological changes in the lumbar intervertebral foramen (LIF) in patients with adult …

Study Design: The prospective cohort study. Objective of the Study: The objective was to
evaluate the relationships between local pressure changes of the intervertebral foramen …

Purpose How the lumbar neural foramina are affected by segmental deformities in patients
in whom degenerative lumbar scoliosis (DLS) is unknown. Here, we used multidetector-row …

Object The theoretical advantage of pars interarticularis repair over spinal fusion to correct
pars defects is that the treatment is a direct osteosynthesis that preserves motion at the …

Study Design: In vivo measurement of lumbar foramen using computed tomography and an
axial loading device in healthy young subjects. Objective: To investigate the effects of axial …
