title: Clinical outcomes in patients after lumbar disk surgery with annular reinforcement device: two-year follow up.
abstract: Annular Reinforcement Device represents a modification of operative treatment of intervertebral disk herniation. It is a prosthesis that is anchored into the body of the vertebra. The intradiscal part of the implant is placed in the inner part of the annulus fibrosus defect. The aim of this technique is to reduce the incidence of reherniation and the degree of intervertebral space collapse, which is the most frequent adverse effect of diskectomy. Clinical outcomes of the treatment group indicated a statistically significant improvement with respect to the control group. Furthermore, over the period of two years, no cases of symptomatic reherniation were recorded. Considering that no serious complications occurred during the procedures, it would appear that this is an implant that, given its encouraging results, should be further verified in carefully designed future studies.
