Dejerine - Klumpke's syndrome

Also known as outlined, low nerve root syndrome; Brachial plexus lower syndrome; Cable or medial brachial plexus neuritis. Cause pathogenesis involving the brachial plexus (C8 - T1) medial Faso and the sympathetic nerve fiber lesions. Infections and tumors accounted for 50%, accounting for 50% trauma. Clinical manifestations hand and arm medial hypersensitivity or sensory loss, hand weakness, then paralysis. Interosseous muscle, hypothenar muscle, the flexor carpi ulnaris and flexor mean shrinking. Accompanied Horner's syndrome. Differential diagnosis (1) brachial plexus neuritis (brachial plexus neuritis) often appear in the adults, often catch cold, influenza after acute or subacute onset of pain in the neck first pole in the upper and clavicle, the rapid expansion of the posterior shoulder-length hair, and a few days later that spread to the arm, forearm and hand. At the beginning of the pain was intermittent, it soon shall be sustained and extended to the entire upper extremity. Patients taking the arm elbow flexion posture, and to avoid activities to ease the pain. Stem brachial plexus (a clavicle, or axillary fossa and other places) has obvious tenderness. The outreach arm or move for traction on the brachial plexus when induced pain, upper limb muscle strength decreased tendon reflexes, the initial active, but soon reduce or disappear, muscle atrophy and skin sensory dysfunction is not obvious. Due to the time of brachial plexus were involved, not just performance brachial plexus lower levy group, there brachial plexus and the upper central levy group. (2) locking rib and neck rib syndrome (costoclavicular syndrome and nec k of chest) clavicle and the first rib narrow region from the former scalene, cervical rib and normal or congenital malformation of the first rib brachial plexus compression can be caused C8 and T1 nerve damage, have sensory-motor symptoms. Age 30 to 50 years old, middle-aged and older women styles. (3) apical lesions caused brachial plexus C8 - T1 lower extremity pain in the neck damage to the limb diffuse, associated with the lower part of the brachial plexus palsy, sometimes accompanied by Horner's syndrome. Apical lesions The most important thing is the Department of apical lung cancer.
