Case report of a 49-year-old woman with a lower thoracic disc herniation mimicking acute lumbosacral radiculopathy. ⋯ A case of thoracic disc herniation mimicking an acute lumbosacral radiculopathy is presented. Compression of the lumbosacral spinal nerve roots at the lower thoracic level after exit from the lumbar enlargement may be the mechanism for this unusual presentation.

Comparative Study
The use of coralline hydroxyapatite with bone marrow, autogenous bone graft, or osteoinductive bone protein extract for posterolateral lumbar spine fusion.
A posterolateral lumbar arthrodesis animal model using coralline hydroxyapatite as a bone graft substitute. ⋯ These data indicate that coralline hydroxyapatite with bone marrow was not an acceptable bone graft substitute for posterolateral spine fusion. When combined with autogenous iliac crest bone graft-coralline hydroxyapatite served as a graft extender yielding results comparable to those obtained with autograft alone. Coralline hydroxyapatite served as an excellent carrier for the bovine osteoinductive bone protein extract yielding superior results to those obtained with autograft or bone marrow.

Multicenter Study Comparative Study Clinical Trial
Laparoscopic fusion of the lumbar spine: minimally invasive spine surgery. A prospective multicenter study evaluating open and laparoscopic lumbar fusion.
Two hundred-forty consecutive patients underwent laparoscopic instrumented interbody fusion using custom-designed instrumentation and BAK (Sulzer Spine Tech, Minneapolis, MN) fusion cages. The surgeries were performed at eight spine centers during U.S. Food and Drug Administration investigational device evaluation clinical trials. This cohort was compared with 591 consecutive patients undergoing open anterior fusion with the same device. ⋯ The laparoscopic procedure is associated with a learning curve, but once mastered, it is effective and safe when compared with open techniques of fusion.

Comparative Study
Complications in the adult spinal deformity patient having combined surgery. Does revision increase the risk?
A comparison of short-term complications (within 6 months after surgery) between primary combined adult spinal deformity (multilevel scoliosis, kyphosis, fixed coronal-sagittal imbalance) surgeries (n = 18) and combined adult spinal deformity revision surgeries (n = 26). ⋯ The risk of major and minor complications within the first 6 months after surgery is not necessarily greater in the revision group than in the primary group of patients with adult spinal deformity who have combined surgeries. Total parenteral nutrition does appear to have a role in many of these patients.
