Lumbar discectomy is a very effective therapy for neurological decompression in patients suffering from sciatica due to hernia
nuclei pulposus. However, high recurrence rates and persisting post-operative low back pain in these patients require serious
attention. In the past decade, tissue engineering strategies have been developed mainly targeted to the regeneration of the
nucleus pulposus (NP) of the intervertebral disc. Accompanying techniques that deal with the damaged annulus fibrous are now
increasingly recognised as mandatory in order to prevent re-herniation to increase the potential of NP repair and to confine
NP replacement therapies. In the current review, the requirements, achievements and challenges in this quickly emerging field
of research are discussed.
