ABSTRACT

Acute and chronic pain are public health issues that clinicians have been battling for years. Opioid medications have been a treatment option for both chronic and acute pain; however, they can cause unwanted complications and are a major contributor to our present opioid epidemic. The sacroiliac (SI) joint is a common cause of both acute and chronic low back pain. It affects about 15-25% of patients with axial low back pain, and up to 40% of patients with ongoing pain following lumbar fusion. Recent advances in the treatment of SI joint pain have led to the development of a wide variety of SI joint fusion devices. These fusion devices seek to stabilize the joints themselves in order that they become immobile and, in theory, can no longer be a source for pain. This is a minimally invasive procedure aimed to address chronic pain without subjecting patients to lengthy surgery or medications, including opioids with the potential for addiction and abuse. Minimally invasive SI fusion can be performed by a lateral approach (i.e., iFuse, Tricor) or posterior approach (i.e., CornerLoc, LinQ, Rialto). The posterior approach requires the patient to be in the prone position but allows for less disruption of muscles with entry. More data are necessary to determine which fusion system may be best for a particular patient. SI fusion devices are a promising way of treating chronic lower back pain related to the SI joint. This narrative review will discuss various types of SI fusion devices, and their potential use in terms of their safety and efficacy.

ABSTRACT

Chronic migraine is a particular classification of a headache that is typically unilateral and pulsatile and lasts for at least 3 months. Owing to its high prevalence and detrimental impact on personal, social, and economic aspects of patient lives, much desire has gone into fully understanding the pathogenesis of migraine, and to search for therapeutic agents. In addition to current therapeutics such as triptans, ergotamine, and monoclonal antibodies targeting calcitonin gene-related peptide receptors, vitamin B12 has been investigated for its possible use as a prophylactic agent for migraines. Specifically, the observed effects of vitamin B12 on nitric oxide and homocysteine prompt further investigation of its underlying mechanisms in migraine pathophysiology. In this comprehensive review, we provide a brief overview of migraines and current therapies while focusing on the promising role of vitamin B12 as a possible treatment option for chronic migraine management.
