RESUMEN
Adequate nutritional intake is a key component of uncomplicated recovery from spinal surgery. Though much in the literature exists regarding its importance, specific dietary regimens for spinal surgery remain understudied, and little is available in compiling both preoperative and postoperative nutritional recommendations for patients. The complexity that may exist with these recommendations -- especially in the context of patients with diabetes or those who use substances -- has led in recent years to the development of protocols such as Enhanced Recovery After Surgery (ERAS), which gives providers a guideline upon which to base their nutritional counselling. More innovative regimens, such as the use of bioelectrical impedance analyses to assess nutritional status, have also emerged, resulting in a vast array of dietary recommendations and protocols for spinal surgery. In the following paper, we aim to compile a few of these guidelines, comparing various preoperative and postoperative nutritional strategies as well as making note of special considerations, like patients with diabetes or those who use substances. We also work to overview several such dietary "protocols" available in the literature, with a special focus on ERAS and more recent regimens like the Northwestern High-Risk Spine Protocol. We briefly mentioned preclinical work on novel nutritional recommendations as well. Ultimately, we hope to highlight the importance of nutrition in spinal surgery and address the need for greater cohesion of dietary strategies already in existence.
RESUMEN
The assessment and treatment of vertebral primary bone lesions continue to pose a unique yet significant challenge. Indeed, there exists little in the literature in the way of compiling and overviewing the various types of vertebral lesions, which can often have complicated intervention strategies. Given the severe consequences of mismanaged vertebral bone tumors-including the extreme loss of motor function-it is clear that such an overview of spinal lesion care is needed. Thus, in the following paper, we aim to address the assessment of various vertebral primary bone lesions, outlining the relevant nonsurgical and surgical interventional methods. We describe examples of primary benign and malignant tumors, comparing and contrasting their differences. We also highlight emerging treatments and approaches for these tumors, like cryoablation and stereotactic body radiation therapy. Ultimately, we aim to emphasize the need for further guidelines in regard to correlating lesion type with proper therapy, underscoring the innate diversity of vertebral primary bone lesions in the literature.
