Basivertebral Nerve Radiofrequency Ablation (Intracept): Procedural Technique.

Intraosseous basivertebral nerve ablation is indicated for the treatment of chronic vertebrogenic low back pain with failure of at least 6 months of conservative treatment. This article details patient positioning and setup, step-by-step instructions for the procedure, and postoperative management. Pearls and pitfalls are also discussed. In addition, an instructional procedure video accompanies this paper and can be found online (at https://vimeo.com/791578426/de0e90cfbe).

Complete Resolution of Refractory Axial Low Back Pain After Myomectomy.

ABSTRACT: We present a case of a 39-yr-old woman with a 3-mo history of axial low back pain who was found to have a 3.8-cm uterine fibroid, which was initially thought to be an incidental finding. Her low back pain failed to respond to conservative management, and she was eventually referred to gynecology. Her pain subsequently resolved after myomectomy. To the best of our knowledge, complete resolution of low back pain after myomectomy has not been previously described in the literature. Although uterine fibroids are commonly noted on imaging, they are often ignored. We encourage clinicians to consider fibroids as pain generators, especially when treating patients with refractory axial low back pain.

The Fluoroscopic-Guided Cervical Transarticular Epidural Steroid Injection.

ABSTRACT: The epidural space is commonly accessed via an interlaminar or transforaminal approach to administer corticosteroids for radicular pain. An alternative is a transarticular approach, which may be considered when conventional access to the epidural space is either not desired or contraindicated. This approach has been described in the cervical spine using computed tomography guidance but not fluoroscopic guidance. We describe a cervical transarticular approach to the epidural space under fluoroscopy and review the computed tomography-guided literature. The risks of transarticular epidural injections are likely low given that when performed prudently, they avoid direct contact with the vertebral artery, spinal medullary arteries, venous plexus, spinal cord, and nerve roots.

When Clinical Diagnosis Differs From Advanced Imaging: A Case Series of Disc Herniations Causing Radiculopathy and Review of Aberrant Nerve Root Innervation.

ABSTRACT: Radiculopathy is diagnosed using a combination of history, physical examination, and imaging. Unfortunately, well-established dermatomal and myotomal maps are an oversimplification of the convoluted nature of spinal sensory and motor innervation. When clinical presentation and imaging seemingly contradict one another, it is important to consider variant innervation patterns. This article presents three patients with objective dermatomal and/or myotomal deficits due to disc herniations whose clinical presentations are "textbook" for nerve root pathology that is adjacent to the nerve root that is actually compromised. In addition, the literature is reviewed to discuss the history of dermatomal and myotomal maps, the effectiveness of a clinician's ability to determine the precise pathologic disc and nerve root level in patients presenting with radiculopathy, and anatomical explanations as to why inconsistencies such as those seen in the patients in these cases exist.

Telemedicine and current clinical practice trends in the COVID-19 pandemic.

Telemedicine is the medical practice of caring for and treating patients remotely. With the spread of the coronavirus disease-2019 (COVID-19) pandemic, telemedicine has become increasingly prevalent. Although telemedicine was already in practice before the 2020 pandemic, the internet, smartphones, computers, and video-conferencing tools have made telemedicine easily accessible and available to almost everyone. However, there are also new challenges that health care providers may not be prepared for, including treating and diagnosing patients without physical contact. Physician adoption also depends upon reimbursement and education to improve the telemedicine visits. We review current trends involving telemedicine, how pandemics such as COVID-19 affect the remote treatment of patients, and key concepts important to healthcare providers who practice telemedicine.

Caudal Epidural Steroid Injections in the Setting of Remaining on Antithrombotics: A Retrospective Study.

BACKGROUND: The American Society of Regional Anesthesia currently recommends ceasing antithrombotic medications for all spinal epidural steroid injections, however there is a paucity of data on the true risk of spinal epidurals via various approaches versus the risk of cessation of an agent as it relates to the underlying medical condition. OBJECTIVE: This study evaluated the complication rate of caudal epidural steroid injections in patients who remain on antithrombotic medications. STUDY DESIGN: Retrospective chart review. SETTING: Physiatric Spine Clinic in Orthopedic Specialty Office and Surgical Center. METHODS: A retrospective chart review was performed identifying patients (n = 335) who received a caudal epidural steroid injection (n = 673) from June 2015 through April 2020. Patients were included if they had received the injection while taking an antithrombotic medication. Patients were excluded if they were not taking an antithrombotic. The patient's age, indication for the injection including magnetic resonance imaging or computed tomography findings, antithrombotic medication, the medical condition requiring an antithrombotic, and any complications following the injection were collected via chart review. RESULTS: Of the 443 injections included in the study, 51 encounters were lost to follow-up. Of the other 392 injections, there were no reported complications, regardless of the patient's imaging findings, age, the antithrombotic medication used, or the underlying medical condition for which an antithrombotic medication was indicated. LIMITATIONS: This is a retrospective study. Therefore, a prospective study may have yielded fewer encounters lost to follow-up. Patients were not contacted directly after the procedure and chart reviews were utilized to evaluate for complications, which was limited to a patient's reporting of perceived complications without any imaging. CONCLUSIONS: We conclude that caudal epidural steroid injections can be performed safely in patients while taking antithrombotic medications. Catastrophic events have been observed in patients who have discontinued antithrombotic agents preceding procedures. Thus, discontinuing antithrombotic medications may pose a greater risk than benefit for patients on an antithrombotic medication who have painful lumbar radiculopathy.

Intrathecal baclofen withdrawal: A rare cause of reversible cardiomyopathy.

Baclofen is commonly used to treat spasticity of central etiology. Unfortunately, a potentially lethal withdrawal syndrome can complicate its use. This is especially true when the drug is administered intrathecally. There are very few cases of baclofen withdrawal leading to reversible cardiomyopathy described in the literature. The authors present a patient with a history of chronic intrathecal baclofen use who, in the setting of acute baclofen withdrawal, develops laboratory, electrocardiogram, and echocardiogram abnormalities consistent with cardiomyopathy. Upon reinstitution of intrathecal baclofen, the cardiomyopathy and associated abnormalities quickly resolve. Although rare, it is crucial to be aware of this reversible cardiomyopathy to ensure its prompt diagnosis and treatment.

Management of retinal vasoproliferative tumor associated with ROP by plaque brachytherapy.

The authors report a secondary exudative vasoproliferative tumor of the retina associated with retinopathy of prematurity, managed by plaque radiotherapy. A 15-year-old girl with a history of mild, stable retinopathy of prematurity in both eyes noted progressively reduced visual acuity to hand motions in the left eye. Examination disclosed a vasoproliferative tumor of 10-mm base and 3.5-mm thickness with near total (macula-off) exudative retinal detachment. She was treated with iodine-125 plaque radiotherapy, giving apex dose of 40 Gy over 4 days. The tumor regressed to 1.9 mm and retinal detachment resolved 8 months following therapy. Epiretinal membrane with significant macular pucker and edema later developed and was managed with pars plana vitrectomy and membrane peeling. Visual acuity was counting fingers due to photoreceptor loss. Retinopathy of prematurity is a rare cause of vasoproliferative tumor. Iodine-125 plaque radiotherapy can lead to tumor regression and reattachment of the retina in such cases.
