The authors assessed the clinical and imaging findings and late outcome in 50 patients with whiplash-type neck distortions (17 men, 33 women, mean age 33 years). ⋯ A high incidence of discoligamentous injuries was found in whiplash-type distortions. Most patients with severe persisting radiating pain had large disc protrusions on MRI that were confirmed as herniations at surgery. Neck and radiating pain were alleviated by early disc excision and fusion.

Various techniques of percutaneous lumbar disc surgery have become popular for treating lumbar disc herniations. There is a vast and increasing body of literature on this topic that consists mainly of retrospective, uncontrolled clinical studies, technical articles, and case reports. A literature analysis revealed two different techniques, both termed "percutaneous discectomy." One is the selective removal of nucleus pulposus from the herniation site with various manual and automated instruments under endoscopic control (percutaneous nucleotomy with discoscopy, arthroscopic microdiscectomy, percutaneous endoscopic discectomy); the other is the removal of nucleus pulposus from the center of the disc space with one single automated instrument (automated percutaneous lumbar discectomy) to achieve an intradiscal decompression. ⋯ There is no scientifically proven validity of automated percutaneous lumbar discectomy compared with standard surgical methods and chemonucleolysis. The majority of the articles analyzed did not fulfill the selection criteria of Spine. Additional prospective, randomized and controlled studies are needed to define the eventual role of percutaneous lumbar discectomy on a scientific basis.
