      Increased scrutiny of the allocation of health care dollars makes the identification of factors influencing treatment outcomes important. Few studies have examined the relationship between ethnicity and the efficacy of chronic pain management interventions (as opposed to acute pain syndromes). Radiofrequency application (RFA) is a common treatment modality for pain due to zygapophyseal joint (z joint) disease. This survey reviewed the efficacy of RFA in African American (AA) and non-Hispanic Caucasian patients. This study is a retrospective chart review of patients who underwent RFA to the L3, L4 medial branch nerves, dorsal ramus of L4, and the accessory nerve from the S1 dorsal ramus to the L5-S1 z joint.
    • Neurologic Deficit Following Ultrasound Guided Femoral Nerve Block

      Ultrasound provides real time visualization of peripheral nerves while performing a peripheral nerve block. We present a case of post operative neural dysfunction following ultrasound guided femoral nerve block on a patient undergoing left knee arthroscopy.

      The ability to provide comfort and relieve pain during the postoperative period is a priority in the care of the surgical patient. Epidural anesthesia is widely used to manage postoperative pain. The epidural infusion of local anesthetics combined with opioids provides excellent pain relief. It also reduces intra- and postoperative narcotic requirements, leading to earlier mobilization and faster discharge. However, epidural analgesia carries risks for the patient. This presentation reports on the risk of treating a patient with thrombolytics while receiving epidural analgesia.
