Comparative Study
Kinematic analysis of lumbar and hip motion while rising from a forward, flexed position in patients with and without a history of low back pain.
This study analyzed two groups of individuals during return to an upright position (extension) from a forward, bent position. Group 1 (n = 12) included individuals with no history of low back pain who were currently asymptomatic, and group 2 (n = 12) included individuals with no history of low back pain. ⋯ Participants who were currently asymptomatic but had a history of low back pain moved in a manner similar to that of participants with no history of low back pain except that they demonstrated greater lumbar motion and velocity during the initial phase of extension. This may have been the result of low back pain or a contributing factor in recurrent low back pain.

Postoperative changes in the lumbar spine were studied retrospectively in patients with adolescent idiopathic scoliosis who had been treated with Cotrel-Dubousset instrumentation. ⋯ Whereas the overall clinical and radiographic results of surgery were satisfactory, the unfused lumbar segments required careful surveillance, especially in the sagittal plane.

A retrospective study about the occurrence of spinal column deformity or instability after multilevel lumbar or thoracolumbar total laminectomy for removal of benign intraspinal tumors in children and young adults. ⋯ Spinal deformity or instability after multilevel lumbar or thoracolumbar total laminectomy is not uncommon in children and adolescents. Limiting laminae removal and facet destruction may decrease this incidence. Fusion may be required to correct post-laminectomy deformity and to stabilize the spine.

Case Reports
Complex regional pain syndrome type 2 (causalgia) after automated laser discectomy. A case report.
This report identifies a case of complex regional pain syndrome Type 2 (causalgia) with sympathetically maintained pain associated with automated laser discectomy. The syndrome's clinical features and its management with sympathectomy are described. ⋯ Complex regional pain syndrome Type 2 with sympathetically maintained pain is a condition that can result in serious disability and can be associated with a number of spinal procedures, including automated laser percutaneous discectomy. Early intervention is recommended to provide long-term resolution of the condition.

A systematic review of published observational studies. ⋯ There is no firm evidence for the presence or absence of a causal relationship between radiographic findings and nonspecific low back pain.
