There was a noticeable absence of bleeding
from the cut end of the bone consistent with the ultrasonic application. There were 11 instances of dural injuries (8.6 %) and two of which were directly associated with the use of ultrasonic device. In no procedure was the use of the ultrasonic scalpel abandoned for use of another instrument due to difficulty in using the device or failure to achieve the desired A-1155463 cell line osteotomy.
Overall, the ultrasonic scalpel was safe and performed as desired when used as a bone cutting device to facilitate osteotomies in a variety of spine surgeries. However, caution should be taken to avoid potential thermal injury and dural tear. If used properly, this device may decrease the risk of soft tissue injury associated with the use of high speed burrs and oscillating saws during spine surgery.”
“Alkanna bracteosa and Alkanna tricophila, Boraginaceae, have been reported to be useful for their anti-inflammatory and wound-healing effects in traditional medicine. Methanol extracts of A. bracteosa and A. tricophila were evaluated for their potential analgesic and anti-inflammatory properties. Alkanna bracteosa was observed to produce a maximum of 42% reduction of hind paw licking
in acute as well as 68% alleviation in Selleckchem BMN 673 inflammatory phase of formalin test in mice and about 30% declination of carrageenan-induced rats paw swelling at doses 100-400 mg kg(-1) in comparison to negative control; on the other hand, A. tricophila required at least 200 mg kg(-1) to exhibit a significant reduction in paw licking or oedemas at the early
phase of formalin test and the late phase of carrageenan test, respectively. Our results suggest that the extracts may be of use for their analgesic and anti-inflammatory effects.”
“Alterations of three-dimensional cervical curvature in conventional anterior cervical approach position are not well understood. The purpose of this study was to evaluate alignment changes of the cervical spine in the position. In addition, simulated corpectomy was evaluated with regard to sufficiency of decompression and perforation of the vertebral artery canal.
Fifty patients with cervical spinal disorders participated. Cervical CT scanning was performed in the neutral and supine position (N-position) and in extension and right rotation MLN8237 in vitro simulating the conventional anterior approach position (ER-position). Rotation at each vertebral level was measured. With simulation of anterior corpectomy in a vertical direction with a width of 17 mm, decompression width at the posterior wall of the vertebrae and the distance from each foramen of the vertebral artery (VA) were measured.
In the ER-position, the cervical spine was rotated rightward by 37.2A degrees A A +/- A 6.2A degrees between the occipital bone and C7. While the cervical spine was mainly rotated at C1/2, the subaxial vertebrae were also rotated by several degrees.
