US-guided Perineural Injections of the Upper Extremity from the Arm to the Wrist

Listen to this summary

The authors investigate the efficacy and safety of ultrasound (US)-guided perineural injections for diagnosing and treating upper extremity neuropathies. They emphasize the importance of precise nerve localization and detailed anatomical knowledge in performing these injections, which can provide immediate pain relief and assist in confirming specific neuropathies prior to surgical intervention. The paper includes a review of relevant nerve anatomy, injection techniques, and case examples to illustrate best practices.
