Abstract
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.

Abstract
BACKGROUND: The consequences of suffering postoperative complications in elderly undergoing spinal surgeries may be different compared to younger patients. The primary objective of this study was to identify the types and frequency of medical complications and mortality rates in patients 80 years of age or older undergoing elective spinal fusion surgeries for degenerative spinal disease.
METHODS: A prospective observational study with a retrospective chart review was performed, which included all consecutive patients ≥80 years old undergoing elective spinal fusion surgeries from May 2012 to August 2015. We identified a total of 95 patients, of which 39 cervical and 56 lumbar surgeries were performed. There were 41 female and 54 male patients with the mean age of 82.8 years (range, 80-91). The perioperative complications were allocated into the following categories: infection, pulmonary, cardiac, gastrointestinal, hematologic, urologic, neurovascular, thromboembolic, and other. Baseline and postoperative clinical outcome scores were compared to evaluate efficacy.
RESULTS: The mean follow-up time was 14.8 months (range, 5 days to 37 months) with an overall mortality rate of 8.4%. The 30-day, 90-day, and 1-year mortality rates were 2.1, 2.1, and 4.2%, respectively. There were 53.9 and 71.4% patients with complications in the cervical and lumbar patient groups, respectively. The presence of general comorbidities and the number of intervertebral levels predicted the occurrence of perioperative complications. Also, longer OR times were associated with a higher number of complications per patient and the occurrence of a UTI. Dysphagia was a significant predictor in developing pneumonia and atelectasis.
CONCLUSIONS: The incidence of perioperative medical complications and mortality rates in octogenarians undergoing elective spinal surgeries are quite high. The benefits of having surgery must be weighed against the risks of not only surgical but also adverse medical events. An informed decision-making process should include discussion of potential postoperative morbidity specific to this patient population in order to guide patient’s acceptance of higher risks and expectations postoperatively. It is also important to identify potential complications and adapt preventive measures in order to help minimize them in this patient population.
