Case Reports
Reconstruction after total en bloc sacrectomy for osteosarcoma using a custom-made prosthesis: a technical note.
A report of an innovative technique to restore the lumbosacral junction after resection of primary highly malignant osteosarcoma of the sacrum involving the whole sacrum, soft tissues, and adjacent posterior parts of both iliac wings. ⋯ In planning and performing a total sacrectomy, including substantial parts of iliac wings, a three-dimensional real-sized model offers surgeons distinct advantages. Wide bony resection margins can be drawn on the model, and an individual custom-made prosthesis to re-establish spinopelvic continuity can be designed and tested before the intervention.

The case reports of three pregnant patients with lumbar disc herniation causing cauda equina syndrome or severe neurologic deficits are presented to illustrate that disc surgery during gestation is a safe method of management. ⋯ Although extremely rare, cauda equina syndrome and severe and/or progressive neurologic deficit caused by lumbar disc displacement can occur during pregnancy. The prevalence of symptomatic lumbar disc herniation during pregnancy may be on the increase because of the increasing age of patients who are becoming pregnant. These cases showed, and the literature confirms, that pregnancy at any stage is no contraindication to magnetic resonance imaging scan, epidural and/or general anesthesia, and surgical disc excision.

A systematic review of randomized controlled trials was performed. ⋯ There is moderate evidence showing that multidisciplinary rehabilitation for subacute low back pain is effective, and that work site visit increases the effectiveness, but because the analyzed studies had some methodologic shortcomings, an obvious need still exists for high-quality trials in this field.

A systematic review of randomized controlled trials. ⋯ Behavioral treatment seems to be an effective treatment for patients with chronic low back pain,but it is still unknown what type of patients benefit most from what type of behavioral treatment.

Randomized Controlled Trial Clinical Trial
Randomized controlled trial of percutaneous intradiscal radiofrequency thermocoagulation for chronic discogenic back pain: lack of effect from a 90-second 70 C lesion.
A prospective double-blind randomized trial in 28 patients. ⋯ Percutaneous intradiscal radiofrequency thermocoagulation (90 seconds, 70 C) is not effective in reducing chronic discogenic low back pain.
