CRPS diagnosis was confirmed according to the following criteria: continued pain disproportionate (allodynia) to the inciting event, foot hyperesthesia, skin color (redness), stiffness, and weakness of the foot and ankle (positive Budapest criteria). After six months, CRPS was suspected and the patient referred to a pain medicine specialist. After fixation and immobilization, the foot remained painful and swollen, while the healing of the fracture was considered to be favorable. We present the case of a mid-60-year-old male who suffered a tear of the right posterior tibial tendon due to a motor vehicle accident years ago. In this case report, we present a patient with CRPS refractory to t-SCS who was successfully treated with DRGS. The authors concluded that DRG-SCS was a possible salvage option in patients who failed t-SCS in CRPS.Īlthough recent data support DRGS over t-SCS in patients with CRPS, there is little research on effective treatment options in patients who have failed t-SCS. The patient reported immediate improvement in pain. The second patient underwent a surgical revision whereby a DRG-SCS system was added to the existing t-SCS to create a hybrid system with two implantable pulse generators. The first patient reported 90% pain reduction during the DRG trial. Yang and Hunter reported a case series of two CRPS patients who failed t-SCS and were offered DRGS as salvage therapy. Data from the study suggests that DRGS could be used in patients suffering from chronic intractable pain conditions that are refractory to t-SCS. The ACCURATE study was a prospective, randomized, multi-center, controlled clinical trial that demonstrated non-inferiority and superiority of DRGS over traditional SCS (t-SCS) at three months, with results sustained at 12 months. An increasing number of pain centers are using DRGS as either first-line neuromodulation or in cases where SCS has failed. Īdvances in neuromodulation technology have led to the development and implementation of dorsal root ganglia stimulation (DRGS). Yet, no difference in pain was perceived during three to five years following implantation. In a randomized study involving 24 patients with CRPS, SCS plus physical therapy (PT) reduced pain and improved health-related quality of life more than PT alone for up to two years. Spinal cord stimulation (SCS), a procedure in which electrodes are placed into the dorsal epidural space, is an available treatment option for neuropathic pain conditions such as failed back surgery syndrome and CRPS. The incidence of CRPS in population-based studies is between 5 and 26 per 100,000 per year. Type II describes patients with peripheral nerve injury. Type I corresponds to patients with CRPS without evidence of peripheral nerve injury. There are two subtypes of CRPS that have been recognized. The consensus definition of CRPS describes an array of painful conditions that are characterized by regional pain that is disproportionate in time or degree to the usual course of any known trauma or lesion and shows variable progression over time. The Budapest consensus criteria for the clinical diagnosis of CRPS include continuing pain disproportionate to any inciting event and the patient must report at least one symptom in three of the following four categories: sensory, vasomotor, sudomotor/edema, and motor/trophic. Complex regional pain syndrome (CRPS) was previously called reflex sympathetic dystrophy (RSD), “causalgia,” or reflex neurovascular dystrophy (RND).
