A case report. ⋯ Patients with ankylosing spondylitis have a strong susceptibility to spine fracture from minor trauma, which can have devastating outcomes. Nonregion-specific multiple and simultaneous spine fractures can occur, and require thorough radiographic evaluation with imaging of the entire spinal axis, appropriate operative planning, and meticulous perioperative treatment. Preexisting internal spine instrumentation may predispose the ankylosing spondylitis spine to multiple fractures, even following a minor traumatic event. As such, the clinician should be cognizant of the possible existence of multiple and simultaneous fractures in patients with ankylosing spondylitis with preexisting internal spine instrumentation.

Prospective consecutive series. ⋯ Even if the clinical expectations were met, some patients were still dissatisfied. Patients with spinal stenosis (Group 2) seem to have more unrealistic expectations than patients with disc herniation (Group 1).

Comparative Study
The positional magnetic resonance imaging changes in the lumbar spine following insertion of a novel interspinous process distraction device.
Patients with symptomatic lumbar spinal stenosis underwent magnetic resonance imaging to study changes in the lumbar spine in various postures before and after implantation of the X STOP Interspinous Process Distraction Device (St. Francis Medical Technologies, Concord, CA). ⋯ This study shows that the X STOP device increases the cross-sectional area of the dural sac and exit foramens without causing changes in posture.

Comparative Study
The sensitivity and specificity of electrodiagnostic testing for the clinical syndrome of lumbar spinal stenosis.
Prospective, masked, double controlled diagnostic trial. ⋯ This first masked study in the 60-year history of needle electromyography also introduces anatomically validated needle placement, quantified and reproducible examination of the paraspinal muscles, and dual control populations to EDX research in spinal disorders. EDX has statistically significant, clinically meaningful specificity for spinal stenosis and detects neuromuscular diseases that may masquerade as stenosis.

Comparative Study
Symptomatic and asymptomatic movement coordination of the lumbar spine and hip during an everyday activity.
This experimental study analyzed the movements of the lumbar spine and hip while putting on a sock. ⋯ Changes in the lumbar and hip kinematics when putting on a sock were related to back pain and limitation in SLR. Low back pain will affect lumbar-hip coordination.
