Animal model study of three healthy commercial pigs was conducted. ⋯ This near infrared spectroscopy technique monitors changes in oxygenation of the spinal cord, and therefore appears capable of intraoperative warning about impending vascular compromise of the spinal cord.

Randomized Controlled Trial Comparative Study Clinical Trial
Transforaminal epidural steroid injections in lumbosacral radiculopathy: a prospective randomized study.
A prospective study randomized by patient choice from the private practice of a single physician affiliated with a major teaching hospital was conducted. ⋯ Fluoroscopically guided transforaminal injections serve as an important tool in the nonsurgical management of lumbosacral radiculopathy secondary to a herniated nucleus pulposus.

A human cadaveric investigation was conducted to determine the effect that a side-opening injection cannula in monopedicular percutaneous vertebroplasty had on the vertebrae filling pattern. ⋯ A side-opening cannula can improve the cement-filling pattern in monopedicular vertebroplasty, as compared with a standard front-opening cannula. The risk of extravasation is diminished if the cement flow is directed medially.

Clinical Trial Controlled Clinical Trial
Altered motor control strategies in subjects with sacroiliac joint pain during the active straight-leg-raise test.
An experimental study of respiratory function and kinematics of the diaphragm and pelvic floor in subjects with a clinical diagnosis of sacroiliac joint pain and in a comparable pain-free subject group was conducted. ⋯ The study findings formally identified altered motor control strategies and alterations of respiratory function in subjects with sacroiliac joint pain. The changes observed appear to represent a compensatory strategy of the neuromuscular system to enhance force closure of the pelvis where stability has been compromised by injury.
