Brachial plexus injury due to compression: an alternate mechanism of injury: case report and review of the literature.

摘要: We present a case of brachial plexus injury due to compression the nerves from traumatic hematoma, with no associated bone or vascular injury. The paralysis in this was not evident for 48 hours after initial injury, implying that damaged directly. Electromyograms documenting plexopathy were obtained. mechanism is different usual mechanisms trauma. majority injuries are multisystem either extreme traction on direct impact. Downward generally results lesions upper cervical nerve roots, whereas upward lower C8 and T1. symptoms include shoulder, arm, and/or hand parasthesias altered sensation. Temperature color limb may be because damage autonomic nervous system. treatment varies depending time discovered relation inciting Current includes assessing function physical examination, preoperative electromyogram, then repair viable roots injuries.
