Excerpt

Background and Aims: Ultrasound is a promising imaging technique in interventional pain management. It allows real-time identification of the soft tissues, vessels, bony structures and most importantly nerves.
Pulsed radiofrequency (PRF) has been reported as a treatment of peripheral neuropathic pain. Since placement of the electrode in the close proximity of the nerve is extremely important for the success of PRF ultrasound seems to be well suited for this technique.
Methods: To describe an ultrasound guided PRF treatment technique for peripheral neuropathic pain. To illustrate a case series. To outline potential advantages of this technique.
Results: Case series below.
Age Sex Peripheral N Pain Nerve Treated
56 Male Supinator Syndrome Superficial radial
45 Female Supinator Syndrome Superficial radial
45 Female Shoulder Pain Suprascapular nerve
75 Male Meralgia Paresthetica Lateral c. nerve of thigh
68 Male Meralgia Paresthetica Lateral c. nerve of thigh
46 Male Ilioinguinal Neuralgia Ilioinguinal nerve
57 Female Nerve Injury Median Nerve
64 Female Nerve Injury Superficial cervical Plexus
Conclusion: Advantages of ultrasound guided PRF include; Real-time visualization of anatomical structures; Improved safety?; Improved outcome? (specificity of treatment); Improved patient comfort (no blind searching for peripheral nerve); More time efficient; Question of specificity of nerve identification by electrical stimulation avoided; Can apply stimulus on different parts of nerve (circumferential treatment); Can reapply treatment in the presence of local anaesthetic.
