ABSTRACT
The COVID-19 pandemic caused by the SARS-CoV-2 virus has left many unanswered questions for patients with neurological disorders and the providers caring for them. Elderly and immunocompromised patients are at increased risk for severe symptoms due to COVID-19, and the virus may increase symptoms of underlying neurological illness, particularly for those with significant bulbar and respiratory weakness or other neurologic disability. Emerging SARS-CoV-2 vaccines offer substantial protection from symptomatic infection, but both patients and providers may have concerns regarding theoretical risks of vaccination, including vaccine safety and efficacy in the context of immunotherapy and the potential for precipitating or exacerbating neurological symptoms. In this statement on behalf of the Quality Committee of the AAN we review the current literature, focusing on COVID-19 infection in adults with neurological disease, in order to elucidate risks and benefits of vaccination in these individuals. Based on existing evidence, neurologists should recommend COVID-19 vaccination to their patients. For those patients being treated with immunotherapies, attention should be paid to timing of vaccination with respect to treatment and the potential for an attenuated immune response.
ABSTRACT
PURPOSE: We present our preliminary studies using LactoSorb plates (Lorenz/Biomet, Warsaw, IN) for rotator cuff repair in humans. The use and application of this plate are described as an adjunct to prevent hole migration in trough-tunnel repairs of rotator cuff tears. METHODS: Fifty patients with rotator cuff tears documented by magnetic resonance imaging underwent arthroscopic subacromial decompression followed by a mini-open repair of the rotator cuff. Tears were repaired using a trough and tunnel technique, horizontal mattress sutures, and a standard LactoSorb plate. Follow-up was obtained on 45 patients, 26 male and 19 female, with an average age of 61.6 years. The patients were followed-up and evaluated at 5 days, 1 month, 3 months, 6 months, and a minimum of 1 year postoperatively. All surgeries were performed by the same surgeon and followed a similar rehabilitation protocol. RESULTS: There were 89% excellent results, 9% good results, and 2% fair results. There were no poor results. No significant swelling, tenderness, or erythema was noted at the operative site, and there were no infections. Postoperative radiographs at 3, 6, and 12 months did not show any bone erosion. No repeat surgical procedures were necessary. CONCLUSION: The results of our study support the use of LactoSorb bioabsorbable plates in the repair of rotator cuff tears to prevent hole migration and potentially poor results or failures of repairs. The LactoSorb plate appears to maintain its strength during the healing period of the repair and does not elicit any clinically noticeable inflammatory process.
