We report the unusual case of a young patient with reoperation after annuloplasty using the Barricaid® (Intrinsic Therapeutics, Woburn, MA, USA) closure device. Our patient, a 32-year-old man underwent lumbar discectomy and annuloplasty of the level L5-S1. Five years later, the patient presented with a new onset of low-back pain radiating into the right leg. Imaging revealed loosening of the annulus repair device. The device was removed surgically and the patient was pain free thereafter. Annular closure devices such as the Barricaid system aim to improve outcome after lumbar discectomy by reducing the risk of recurrent disc herniation of the same level. Data on long-term follow-up are missing. Here we present, to our knowledge, the first case of symptomatic device loosening.
