OBJECTIVE To investigate the efficacy of ultrasonography (US)-guided injections in patients with low lumbar facet syndrome, compared with that in patients who received fluoroscopy (FS)-guided injections. METHOD Fifty-seven subjects with facet syndrome of the lumbar spine of the L4-5 and L5-S1 levels were randomly divided into two groups to receive intraarticular injections into the facet join...

STUDY DESIGN Technique report and case series. OBJECTIVE The aim of this study was to develop a new surgical technique for anterior reduction in management of unilateral/bilateral facet dislocations and to report the results of 8 patients with successful outcomes associated with this approach. SUMMARY OF BACKGROUND DATA The anterior-only surgical procedure, including discectomy, open reduct...

Superposition eyes are generally thought to function ideally when the eye is spherical and with rhabdom tips in the focal plane of the imaging optics of facet lenses and crystalline cones. Anatomical data as well as direct optical measurements demonstrate that the superposition eyes of moths and skippers often deviate severely from the expected ideal case. Part of the deviation has been attribu...

BACKGROUND A 2-year review of literature from October 2004 to December 2006 was completed to update current scientific evidence on diagnostic utility of facet joint injections. Diagnostic injections are employed to diagnose facet joint pain because available techniques cannot identify the pain generating structure in patients with chronic spinal pain. There is no physical examination technique,...

We are developing a system that improves access to a large, growing image collection by supporting users to collaboratively build a faceted (multi‐ perspective) classification schema. For collections that grow in both volume and variety, a major challenge is to evolve the facet schema, and to reclassify existing objects into the modified facet schema. Centrally managed classification systems of...

BACKGROUND Skeletal and soft tissue damage are often associated with unilateral facet dislocations, which undoubtedly lead to instability of the spine and further increase difficulties in cervical reduction. This type of irreducible facet dislocation is usually accompanied with potential catastrophic consequences including neurological deficit and severe disability. Therefore, a consistent and ...

From a search of MRI reports on knees, 20 patients were identified with evidence of early anteromedial osteoarthritis without any erosion of bone and a control group of patients had an acute rupture of the anterior cruciate ligament. The angle formed between the extension and flexion facets of the tibia, which is known as the extension facet angle, was measured on a sagittal image at the middle...

BACKGROUND AND PURPOSE Thickening of the LF is ascribed to buckling due to DSN. Uncertainty exists as to whether this can occur without DSN. Our primary hypothesis was that facet degenerative changes alone, independent of DSN, can thicken the LF. Our secondary hypothesis was that inflammatory changes surrounding degenerative facet joints may incite thickening. MATERIALS AND METHODS Fifty-two ...
