Randomized Controlled Trial Clinical Trial
The efficacy of antifibrinolytics in the reduction of blood loss during complex adult reconstructive spine surgery.
Controlled study to assess the efficacy of aprotinin and Amicar in reducing blood loss during complex spinal fusions. ⋯ For complex spinal operations with large blood losses, the half-dose aprotinin regimen will reduce blood loss and the need for blood components and may have a role in reducing postoperative lung injury.

Comparative Study
Reliability and validity of the active straight leg raise test in posterior pelvic pain since pregnancy.
A cross-sectional analysis was performed in a group of women meeting strict criteria for posterior pelvic pain since pregnancy (PPPP). The scores on the Active Straight Leg Raise Test (ASLR test) were compared with the scores of healthy controls. ⋯ The ASLR test is a suitable diagnostic instrument to discriminate between patients who are disabled by PPPP and healthy subjects. The test is easy to perform; reliability, sensitivity, and specificity are high. It seems that the integrity of the function to transfer loads between the lumbosacral spine and legs is tested by the ASLR test.

A questionnaire survey was mailed to members of the Cervical Spine Research Society, the Herodiuus Sports Medicine Society, and to members of the authors' Department of Orthopaedics. ⋯ There is no consensus on the postinjury management of many cervical spine-injured patients. Further research, education, and discussion on this topic are needed.

Randomized Controlled Trial Comparative Study Clinical Trial
Nonoperative treatment versus posterior fixation for thoracolumbar junction burst fractures without neurologic deficit.
A prospective clinical trial was conducted. ⋯ Short-segment posterior fixation provides partial kyphosis correction and earlier pain relief, but the functional outcome at 2 years is similar. Early activity to the point of pain tolerance can be safely allowed.

Randomized Controlled Trial Clinical Trial
Periradicular infiltration for sciatica: a randomized controlled trial.
A randomized, double-blind trial was conducted. ⋯ Improvement during the follow-up period was found in both the methylprednisolone and saline groups. The combination of methylprednisolone and bupivacaine seems to have a short-term effect, but at 3 and 6 months, the steroid group seems to experience a "rebound" phenomenon.
