    Study Notes

    Understanding Complex Regional Pain Syndrome (CRPS)

    • CRPS is a chronic pain condition characterized by continuing regional pain that is disproportionate in time to the usual course of any trauma.
    • CRPS has two forms: CRPS-I develops following injury with little or no obvious damage to nerves in the particular extremity, and CRPS-II presents following injury to a nerve.
    • The exact pathophysiology of CRPS is not yet completely understood, but it may be a manifestation of multiple pathophysiologies arising after a tissue or nerve injury to the area.
    • CRPS usually develops after an inciting trauma or injury to an area of the body with CRPS II being notable for injury to the nerve, and the most common affected areas are the limbs.
    • CRPS is characterized by excessive pain in the affected area described as out of proportion to inciting events, with qualities of burning, sharp, or stabbing sensation.
    • There are no specific diagnostic tests to confirm the presence of CRPS, and the criteria for diagnosing CRPS are currently based on a detailed history and physical examination.
    • The differential of CRPS includes posttraumatic neuralgia, diabetic neuropathy, rheumatologic and inflammatory conditions, infectious diseases, arterial or venous occlusive diseases, and factitious disorder.
    • CRPS is best managed by a multidisciplinary approach, and the best approach is with preventative measures.
    • The choice of pharmacological interventions and invasive procedures depends on the stage of CRPS at presentation, and rehabilitation is encouraged at every stage.
    • Emerging therapies for CRPS include the use of ketamine infusion, hyperbaric oxygen, and intravenous immunoglobulin.
    • The prognosis varies for each person with CRPS, and some people experience complete remission from symptoms without treatment, while others may progress to an irreversible crippling state with constant pain despite treatment.
    • Early recognition and appropriate treatment can be effective at preventing a debilitating irreversible chronic state of CRPS.
