Splenius capitis (SPL) electromyograms were recorded using conventional surface and intramuscular wire electrodes simultaneously during various head-neck movements and isometric tasks to test the selectivity of surface electrodes for SPL myoelectric signals. The insertion of bipolar wire electrodes was aided by a computerized tomographical study of each(More)
This preliminary study was conducted to identify a facet joint syndrome in low back pain. Ninety maneuvers and symptoms were compared between patients relieved (responders) and those unrelieved (nonresponders) after intraarticular blocks. Fifty-one patients participated in the study; 11 were excluded from evaluation because of unsuccessful injection into(More)
PURPOSE To investigate the frequency and distribution of end plate marrow signal intensity changes in an asymptomatic population and to correlate these findings with patient age and degenerative findings in the spine. MATERIALS AND METHODS MR imaging studies of the lumbosacral (LS) spine in 59 asymptomatic subjects were retrospectively reviewed by 2(More)
Thirty-two patients underwent periradicular corticosteroid injections with a lateral percutaneous approach under fluoroscopic guidance, to treat 34 foci of chronic cervical radiculopathy unresponsive to medical treatment alone. The mean evolutionary trends for radicular and neck pain relief were significant at 14 days (P <.001) and at 6 months (P <.001).(More)
The patterns of activation of splenius capitis, semispinalis capitis, transversospinalis, and levator scapulae muscles were studied during various head-neck positions, movements, and isometric tests in 19 healthy human subjects. Myoelectric activities were recorded with intramuscular bipolar wire electrodes. Cervical computerized tomography of each subject(More)
To determine the postural role of longus colli (LC) and dorsal neck muscles, we have studied the relationship between their cross-sectional areas related to their force of contraction and the lordosis and the length of the cervical spine. This study was carried out in 36 healthy subjects. Muscle cross-sectional areas were measured by computerized(More)
In summary, septic arthritis of a lumbar facet joint has been rarely discussed in the literature [1, 4]. In this case report the histological and bacteriological diagnosis was established by percutaneous needle biopsy guided by fluoroscopy and the response to treatment was confirmed by CT scans.
BACKGROUND Extensive spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in the United States, and the concomitant increase in severe invasive staphylococcal infections, including osteomyelitis, in healthy children, has led to renewed interest in Panton-Valentine leukocidin (PVL). However, the pathogenetic role of PVL in(More)
A randomized clinical trial was conducted to compare the results of automated percutaneous discectomy with those of chemonucleolysis in 141 patients with sciatica caused by a disk herniation; 69 underwent automated percutaneous discectomy and 72 were subjected to chemonucleolysis. The principle outcome was the overall assessment of the patient 6 months(More)
OBJECTIVE The objective of this article is to describe the different stages of spinal neuroarthropathy as assessed by CT and MRI and to discuss their contribution to the management of affected patients. CONCLUSION Early-stage findings consisted of inflammatory changes involving adjacent vertebral endplates and mimicking degenerative disk disease with(More)
