Brachial plexus injury
Brachial plexus injury: damage to the C5-T1 nerve network serving shoulder, arm, and hand, from trauma, birth traction, gunshot, or tumor. Surgery timing under 6 months and nerve transfers improve recovery.
Brachial plexus palsy in newborn
Neonatal brachial plexus palsy (Erb's palsy, obstetric brachial plexus injury) is flaccid arm paralysis in newborns from C5–T1 nerve injury during birth; incidence about 1.7 per 1000, mostly upper-trunk, often recovering spontaneously.
Erb's palsy
Erb paralysis (Erb's palsy, Erb-Duchenne paralysis) is upper-arm weakness from C5–C6 upper trunk brachial plexus injury, mostly at birth; ~90% of neonatal brachial plexus palsies, often with shoulder dystocia, usually recovering in 3–4 months.
Klumpke paralysis
Klumpke paralysis (Klumpke's palsy, Dejerine-Klumpke palsy): lower brachial plexus palsy of C8-T1 roots from hyperabduction traction or apical tumor compression, causing claw hand, medial hand sensory loss, and Horner syndrome.
Thoracic outlet syndrome due to cervical rib
Thoracic outlet syndrome due to cervical rib (ICD-11 8B91.1): neurovascular compression at the thoracic outlet caused by an extra rib from C7, found in 1.1% of healthy people but 29.5% of TOS patients.
