The incidence of lumbar disc fragment migration is approximately 35%–72% of which 34% are high-grade up-migrated discs. Translaminar keyhole approach is a minimally invasive and true tissue sparing technique which has been applied to approach migrated disc herniation. The unilateral biportal endoscopic approach is an emerging technique among endoscopic spine surgery that combines the advantages of microscopic surgery with endoscopic surgery. In this technical report we demonstrate the surgical technique of performing the translaminar keyhole approach with unilateral biportal endoscopic spine surgery to treat high-grade up-migrated discs. As far as we know, this is the first technical report of unilateral biportal endoscopy with translaminar keyhole approach to treat high-grade up migrated lumbar disc herniation.
Symptomatic cervico-thoracic tandem disc herniation occurs very rarely. On the other hand, cervical disc herniations are common and may be treated via a variety of surgical procedures. Symptomatic upper thoracic disc herniations are extremely rare, and use of a surgical approach in their treatment is controversial due to the narrow operative space within which surgical procedures must be performed. We report an extremely rare case of symptomatic tandem C6-7 and T1-2 disc herniation successfully treated via single-stage, single-incision, C6-7 anterior cervical decompression and fusion, and T1-2 oblique keyhole transcorporeal discectomy. This is the first symptomatic cervico-thoracic tandem disc herniation with its treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
