While these agents are more commonly associated with length-dependent peripheral polyneuropathies, when used in conjunction with radiation therapy or other drug therapy, they may increase the risk of brachial plexus injury. Differential Diagnosis and Treatment Author s: It is important to differentiate root avulsion from brachial plexus injury for treatment and prognostication as complete root avulsions are incapable of regeneration and are not amenable to surgical repair.
Gaps in the evidence-based knowledge. March 7,2: Brachial plexopathy is an injury of the brachial plexus, most commonly caused by trauma.
Even with severe initial injury, electrodiagnostic evidence of recovery is expected within months with many showing full re-innervation by one year. The presence of brachial plexus injury in polytrauma is of poor prognostic significance.
Clinically, preganglionic injuries eg, root avulsions can be associated with Horner syndrome disruption of the autonomic trunkmedial scapular winging injury to long thoracic and dorsal scapular nerveand denervation of the cervical paraspinal muscles.
No equipment or strengthening has been proven to decrease the risk of brachial plexus injury. Plexopathy results from direct axonal damage, demyelination, and microvascular infarction and more indolently because of compression caused by fibrosis, commonly seen following radiation therapy for breast, lung, lymphoma, and head and neck cancer.
There are no required laboratory analyses in the work-up of brachial plexopathy however basic laboratory assessments may be helpful in ruling out alternative causes of weakness or in looking for triggers of NA. Serial casting may initially improve more severe contractures and nighttime splinting may be effective in preventing contracture progression.
Nerve transfers may borrow from other important nerve such as the phrenic nerve, intercostal nerves, and spinal accessory nerve.
Brachial plexopathies: classification, causes, and consequences.
Commonly affects the infraclavicular plexus. Similar to traumatic spinal cord injury, these injuries are most often associated with motor vehicle and often motorcycle collisions. Identification and avoidance of repetitive activities, extreme range of motions and excessive load carriage via shoulder straps that induce pain or weakness is critical. Traumatic root avulsions may connsequences in conjunction with brachial plexus injuries in the plexopathoes of high-energy stretch.

LAC, median thumbmedian second digit Posterior cord: Wikisource 0 entries edit. In post-ganglionic injury, it is prudent to wait for 3—4 months for spontaneous improvement to occur.
Available or current treatment guidelines Pain: Consequenes C Lateral cord: RTW status should be determined only after maximum medical improvement. Wikiversity 0 entries edit. Neonatal brachial plexopathy may be associated with glenohumeral joint dysplasia, joint contractures shoulder, elbow, supinationposterior shoulder dislocation, or length discrepancies.
Further research is needed to assist in classificarion prognosis before 2 months and establishing the most effective timing for surgical intervention. Axon loss is best determined during nerve conduction studies by decreased amplitude in comparison with the contralateral side if unaffected.

Retrieved from ” https: Lehman, MD Comments are off. Potential donors for nerve transfers are considered and availability of these checked. LAC, median thumb Middle trunk: Postganglionic injuries typically carry a better prognosis because they often demonstrate greater spontaneous recovery and are more amenable to surgical repair. The test is considered positive for TOS if it induces progressive pain in neck to shoulder to arm, paresthesias in the forearm or fingers, arm pallor when elevated and hyperemia when lowered vascular TOSor reproduction of the usual symptoms that involve the entire arm.
Outcomes and rehabilitation after surgery: Medial brachial fascial compartment syndrome: Intraoperative neurophysiology may help in diagnosing root avulsions and determining viable donor nerve for surgery in the event of equivocal pre-operative studies. An integrated care team should include a physiatrist, neurologist, neurosurgeon, hand surgeon, occupational therapist, physical therapist, electrodiagnostician, pain specialist, and possibly an oncologist or pediatric neurologist.

Definition Brachial plexopathy is an injury of the brachial plexus, most commonly caused by trauma. Radial, ulnar, and carotid pulses Allen test: Counseling regarding etiology, treatment options, prognosis for recovery, and prevention of secondary complications is a critical component of the overall plan of care.
History Duration of symptoms Characteristics of pain, sensory changes, weakness, and muscle atrophy Infection, activity, or injury associated with onset Change in symptoms with change in head, neck, or arm position Autonomic symptoms Change in function activities of daily living [ADLs], sports performance, etc Personal or familial history of neoplasm, radiation, chemotherapy, demyelinating disorders, diabetes or previous brachial plexopathy Details of pregnancy and delivery in neonatal patients Physical examination Standardized neurologic examination Tests of manual muscle strength, sensation, and reflexes commensurate with the affected portions of the plexus May include Tinel sign over the brachial plexus Vascular: Report on 99 patients.
From proximal to distal, its elements are the following: Of the 14 people who were not working, 10 associated their injury with their unemployment. Views Read View history. Lower roots C8-T1 are the most susceptible to avulsion.
Spontaneous recovery is rare with complete axonal discontinuity, manifested by complete absence of CMAPs, absence of motor unit action potentials MUAPs despite good effort, and abnormal spontaneous activity. Return to work RTW: The axonal viability index, the ratio of amplitude of the involved side to the unaffected limb, has been used for electrodiagnostic prognostication in newborns.
