Semistructured interviews, group discussions, and a mailed survey. ⋯ Having all the players onside may be essential, but it is not sufficient to bring about action in workplace strategies for patients with low back pain. If early return to modified work is effective, implementing it may require interventions targeted at identified barriers.

Clinical Trial
Clinical outcome results of pedicle subtraction osteotomy in ankylosing spondylitis with kyphotic deformity.
A prospective study was performed in 45 patients with ankylosing spondylitis. ⋯ Most of the patients maintained good correction and had good clinical results. Based on the results of this study, pedicle subtraction extension osteotomy is effective for correction of kyphotic deformity in ankylosing spondylitis.

A retrospective follow-up study of spine geometry after posterior instrumentation and fusion for adolescent idiopathic scoliosis (AIS). ⋯ Spinal growth as indicated by an increase in spinal length can be measured in a significant proportion of adolescents with idiopathic scoliosis after posterior instrumentation and fusion. Some of these study participants will develop a crankshaft phenomenon but Cobb angle progression is not a reliable indicator of this complication, since it may occur without any detectable growth of the spine.

Clinical Trial
Diverging intramuscular activity patterns in back and abdominal muscles during trunk rotation.
An intramuscular electromyographic study was performed on trunk rotations during sitting and standing. ⋯ During trunk rotations the activity patterns for various trunk muscles could drastically change, and even be the opposite, between the two body sides, within the same type of task, depending on several factors such as initial position, effort level, sitting or standing, and external shoulder resistance.

A case report is presented involving a subdural hematoma after cervical epidural steroid injection. ⋯ It is important to acknowledge that spinal hematomas can occur after cervical epidural steroid injection, as prompt recognition and treatment could improve the prognosis for recovery. The sequelae of a cervical subdural hematoma after epidural steroid injection remain potentially devastating.
