Meta Analysis Comparative Study
A meta-analysis of autograft versus allograft in anterior cervical fusion.
We performed a metaanalysis of one- and two-level anterior cervical interbody fusion (ACDF) on data derived from published, peer-reviewed journal articles to determine whether there is a difference in fusion rate, graft complications, or clinical outcome in patients undergoing ACDF according to whether autograft or allograft was used. ACDF is a common procedure for cervical spondylotic radiculopathy. Most published studies comparing autograft and allograft have not demonstrated any difference between grafts. ⋯ It was not possible to ascertain whether autograft is clinically superior to allograft. Although autograft has a higher fusion rate than allograft, clinical results do not depend solely on radiographic results. The risk of graft site morbidity and patient preference should be considered when choosing the type of graft for this operation.

Meta Analysis
Anterior thoracoscopic spine release in deformity surgery: a meta-analysis and review.
Videoassisted thoracoscopic surgery (VATS) allows the surgeon to perform an anterior thoracoscopic spine release for spinal deformities. It is an alternative to open thoracotomy. Several years after its introduction the present author gives an update on the indications, surgical techniques, results, and complications of this new technology. ⋯ The VATS procedure has been used with success in most series for pediatric curves (average Cobb angle of 65 degrees or kyphosis of 75 degrees). No report of the surgical outcome (balance, rate of fusion, rib hump correction, cosmetic correction, pain, and patient satisfaction) was available for any series. Further prospective study including these parameters will be required to determine the real benefit of such procedures to the patient, bearing in mind that the correction of spinal deformities is the result of the surgeon's experience, skill, and the available technology.
