A retrospective analysis using prospectively collected data from 3-dimensional computed tomography angiography (3D-CTA). ⋯ The VAs and PPCW vary considerably. Preoperative 3D-CTA provides important information for preventing tragic vascular complications caused by iatrogenic VA injury. Taking the risk of radiation into consideration, we recommend this method for patients at the highest risk for iatrogenic VA injury.

Comparative Study
Comparison of CatWalk analysis and von Frey testing for pain assessment in a rat model of nerve crush plus inflammation.
Assessment of pain-related behavior and immunohistology of the dorsal root ganglion in a rat model. ⋯ Our results demonstrate that the CatWalk system is useful for the measurement of pain-related behavioral change in our rat model in which nociception was indicated at a cellular level. Although further studies are needed, we think that this system is a valid alternative method for the evaluation of models of lumbar disease in rodents.

Randomized Controlled Trial
A randomized controlled trial of limited range of motion lumbar extension exercise in chronic low back pain.
Randomized controlled trial. ⋯ The results suggest that both FullROM and LimROM are equally effective in increasing full ROM lumbar extension strength and producing clinically meaningful improvement in perceived pain and disability.

An in vitro biomechanical study of 3 lumbosacral fixation techniques in human cadaveric lumbar-pelvic spine models. ⋯ The 4-rod technique achieved stable biomechanical effects in lumbosacral fixation. At the L5-S1 junction, the 4-rod technique demonstrated better stability than the constructs using S1 screws or S1 screws plus iliac screws..
