Restoring Segmental Lumbar Lordosis After Failed Previous Fusion at the Same Level

View on ClinicalTrials.gov →
Summary
The restoration of lumbar lordosis is mandatory during lumbar fusion surgery for degenerative disc disease, since not restoring lumbar lordosis adequately may adversely affect surgical outcomes and the patient's quality of life in the follow-up. Revision surgery to restore segmental lordosis at the level of previous spinal fusion is extremely difficult to do and its performance is usually inferior to that of primary surgery. Need to provide a surgical technique to restore segmental lordosis via a posterior approach, which is especially important after failed previous fusion at the same lumbar level.
