Comparative Study Clinical Trial
Temporary external transpedicular fixation of the lumbosacral spine: a prospective, longitudinal study in 330 patients.
In this study, 330 patients with incapacitating low back pain underwent temporary external transpedicular fixation (TETF) of the lumbosacral spine in a prospective trial. ⋯ In this heterogeneous group of chronic patients with low back pain, TETF of the spine (including a placebo trial) does not appear to be of value in selecting suitable candidates for spinal fusion.

Population-based, prospective cohort. ⋯ Most new and recurrent LBP episodes are mild. Less than one third of cases resolve annually, and more than 20% recur within 6 months. LBP episodes are more recurrent and persistent in older adults.

Comparative Study
Long-term results of disc excision for recurrent lumbar disc herniation with or without posterolateral fusion.
A retrospective study assessing the long-term outcomes of repeat surgery for recurrent lumbar disc herniation. ⋯ Repeat surgery for recurrent sciatica is effective in cases of true recurrent disc herniation. Disc excision alone is recommended for managing recurrent disc herniation.

Comparative Study
Balloon kyphoplasty is effective in deformity correction of osteoporotic vertebral compression fractures.
A prospective radiographic analysis of deformity correction during the balloon kyphoplasty procedure. ⋯ The restoration of height in kyphoplasty is attributed to dynamic fracture mobility as well as to the expansion of the inserted balloon tamp.

A retrospective review of spine, chest, and pelvic dimensions of normal CT scans from 1999 to 2004 was performed. ⋯ Pelvic inlet width is an age-independent predictor of pediatric chest width and thoracic dimensions that may be used to assess thoracic and spine growth in early onset spine deformity patients.
