Surgical Treatment Comparison for Recurrent Lumbar Disc Herniation
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to compare patients who underwent decompression/discectomy with pedicle screw fusion to patients who received decompression/discectomy without fusion.
Condition or disease
Low Back PainRecurrent Lumbar Disc Herniation
Lumbar disc herniations are quite common and typically improve after surgical correction. However, some patients develop recurrent herniations at the same level. Controversy exists as to why reherniated discs occur. Moreover, existing research does not settle the issue of whether a second decompression/discectomy or a repeat decompression/discectomy with pedicle screw fusion is the more successful treatment. This study is designed to compare differences in patient-reported pain, physical function, and satisfaction between the two types of surgery patients.
