Nerve injuries and the fixed dystonias of CRPS.
نویسنده
چکیده
Nerve injury is a known precipitant of complex regional pain syndrome (CRPS). However, is nerve injury a primary cause of CRPS dystonia? In 2009, Oaklander and her colleagues [1] reviewed peripheral aspects of CRPS, asking whether diverse symptoms of this neuropathic pain disorder are linked to small-fiber neuropathies. These authors also described a possible role for large-fiber neuropathies in the etiology of CRPS-fixed dystonias. This hypothesis adds a valuable new perspective to one of the most controversial topics in neurology: the fixed dystonias of CRPS.

(formerly known as reflex sympathetic dystrophy) elicits in absence of any obvious nerve injury, whereas CRPS Type II (previously termed causalgia) is associated with injury to a major peripheral nerve. However, the clinical presentations of the two types are normally indistinguishable. Limb fracture is the most common traumatic event that precedes CRPS. Lesions of the central nervous system, e...

Neurologist S. Weir Mitchell first described "causalgia" following wartime nerve injury, with its persistent distal limb burning pain, swelling, and abnormal skin color, temperature, and sweating. Similar post-traumatic symptoms were later identified in patients without overt nerve injuries after trauma. This was labeled reflex sympathetic dystrophy (RSD; now complex regional pain syndrome type...

Lumbar sympathetic nerve blocks (LSBs) can be performed to determine whether or not a patient’s pain is sympathetically mediated. They can be used as prognostic injections to determine the response to future more permanent sympathectomy or as therapeutic interventions on their own. Common presentations of sympathetically mediated pain include vascular insufficiency and peripheral nerve injuries...

Complex Regional Pain Syndrome (CRPS) is a relatively new term for a clinical entity first described during the American Civil War almost a century and a half ago. Historically, the diagnostic criteria have focused on the sensory (pain, allodynia, hyperalgesia) and autonomic (sudomotor and vasomotor disturbances) features associated with this syndrome (IASP terminology Refs. [10,14]. However, r...

Complex Regional Pain Syndrome (CRPS) can result from trauma or after surgery. It is often difficult to manage effectively. If not recognized early, it can result in significant debilitation. Symptoms attributed to CRPS include neuropathic pain, allodynia, sudomotor changes, and decreased range of motion. It can occur with (Type II) or without (Type I) nerve injury. A number of soldiers sustain...
