Pain Procedures

Image-guided interventional procedures for precise pain diagnosis and treatment.

Ablation

Radiofrequency Ablation (RFA)

Radiofrequency ablation uses electrical current generated by radio waves to heat and destroy specific nerve fibers that transmit pain signals. Under fluoroscopic guidance, a needle electrode is precisely positioned near the target nerve, and controlled thermal energy creates a lesion that interrupts pain transmission.

Lumbar Epidural Steroid Injection

Lumbar epidural steroid injections deliver corticosteroid medication into the epidural space surrounding the spinal cord to reduce inflammation around compressed or irritated nerve roots. This can provide significant pain relief and serve as a bridge to rehabilitation.

Medial Branch Block

A medial branch block is both a diagnostic and therapeutic procedure that involves injecting local anesthetic onto the medial branch nerves that innervate the facet joints. If the patient experiences significant pain relief, it confirms the facet joint as the pain source and supports consideration of radiofrequency ablation.

Sacroiliac Joint Injection

An SI joint injection involves precise placement of corticosteroid and local anesthetic into or around the sacroiliac joint under fluoroscopic or ultrasound guidance. It serves both as a diagnostic confirmation and therapeutic intervention for SI joint-mediated pain.

Spinal Cord Stimulation

Spinal cord stimulation (SCS) delivers low-voltage electrical impulses to the dorsal columns of the spinal cord, masking pain signals before they reach the brain. Modern SCS systems include traditional tonic stimulation, high-frequency (10 kHz) stimulation, and burst stimulation patterns.

Trigger Point Injection

Trigger point injections involve the insertion of a needle into myofascial trigger points — hyperirritable bands within skeletal muscle that are associated with a palpable nodule. The injection of local anesthetic (with or without corticosteroid) disrupts the cycle of muscle spasm and pain.
