Clinical Trial
Four-year follow-up results of lumbar spine arthrodesis using the Bagby and Kuslich lumbar fusion cage.
This was a prospective multicenter clinical trial of a lumbar interbody fusion cage with a minimum of 4 years' follow-up. ⋯ This study indicates that the early positive benefits of interbody fusion cage procedures are maintained through 4 years with acceptably low morbidity.

Comparative Study
A prospective comparison of surgical approach for anterior L4-L5 fusion: laparoscopic versus mini anterior lumbar interbody fusion.
A prospective comparison of 50 consecutive patients who underwent L4-L5 anterior lumbar interbody fusion (ALIF). ⋯ There does not appear to be a significant advantage at the L4-L5 level of the transperitoneal laparoscopic surgical approach when compared with an open mini-ALIF retroperitoneal technique.

Clinical Trial Controlled Clinical Trial
Twelve-month follow-up of a controlled trial of intradiscal thermal anuloplasty for back pain due to internal disc disruption.
Case-control study. ⋯ In carefully selected cases, IDTA can eliminate or dramatically reduce the pain of internal disc disruption in a substantial proportion of patients and appears to be superior to conventional conservative care for internal disc disruption.
