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.

Dorsal root ganglion (DRG) neurons that have dichotomizing axons to the lumbar facet joint and to the sciatic nerve were investigated in rats using a double fluorescent labeling technique. ⋯ In rats approximately 3% of DRG neurons innervating the lumbar facet joints have dichotomized axons projecting to the sciatic nerve.

Transient paraparesis during the operative management of a 16-year-old patient with Scheuermann's kyphosis secondary to thoracic stenosis is reported. ⋯ A treatable cause for paraparesis secondary to the surgical treatment of Scheuermann's kyphosis is presented. The author currently obtains a thoracic magnetic resonance image (MRI) before the surgical correction of any patients with Scheuermann's kyphosis.

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.
