Currently, the best evidence (level 2) exists for the use of IV ketamine and IV morphine for the short-term perioperative treatment of PLP and PO morphine for an intermediate to long-term treatment effect (8 weeks to 1 year). Level 2 evidence is mixed for the efficacy of perioperative epidural anesthesia with morphine and bupivacaine for short to long-term pain relief (perioperatively up to 1 year) as well as for the use of gabapentin for pain relief of intermediate duration (6 weeks).

Buprenorphine/naloxone is being prescribed off-label with increasing frequency for pain management in patients with or without a history of opioid abuse. Severe acute pain is more difficult to control with opioid analgesics in patients taking buprenorphine/naloxone, requiring higher than usual doses. If buprenorphine/naloxone is discontinued to better treat acute pain with other opioids, monitoring for overdose must take place for at least 72 hours.

Background: Neural blockade of the cervical medial branches is a validated procedure in the diagnosis and treatment of cervical zygapophyseal joint pain. Fluoroscopic visualization of the lower cervical medial branch target zones (CMBTZs) in lateral view is sometimes challenging or not possible due to the patient’s shoulders obscuring the target. Large shoulders and short necks often exacerbate the problem. Clear visualization is critical to accuracy and safety. Objective: We aim to describe a method for optimal fluoroscopic visualization of the lower CMBTZs using a modified swimmer’s view. Study Design: A technical report. Setting: A private practice. Methods: Discussion with accompanying fluoroscopic images of the cervical spine, focusing on the lateral aspects of the lower cervical articular pillars in both the traditional lateral view and modified swimmer’s view. Four authors served as volunteers for undergoing fluoroscopic x-rays in both views. Visualization of each lower CMBTZ was attempted and stored. The most caudal, clearly visualized levels were compared in both views for each participant. Results: Visualization of the lower CMBTZs can be successfully obtained with the modified swimmer’s view and in select patients is superior to a lateral view. Limitations: A limitation to this study is the design as a technical report. A future prospective study is warranted. Conclusions: Modified swimmer’s view can serve as a primary method of visualizing the lower CMBTZs or an alternate view when a lateral view is unable to clearly demonstrate target landmarks. This can improve the ease, accuracy, and safety of performing diagnostic cervical medial branch blocks (CMBBs). Key words: Swimmer’s view, cervical medial branch block, facet joint, fluoroscopy
