title: [Congenital paralysis due to compression. Apropos of 4 cases].
abstract: Four cases of congenital dysfunction of major peripheral nerves are reported and discussed. The first patient was a girl born by spontaneous delivery with an area of skin and muscle necrosis on the dorsal aspect of the forearm and a palsy of the three major nerves of the upper limb. The second patient was a boy born by caesarean section with the same necrotic lesions and a palsy of the ulnar and median nerve. The third patient was a boy born uneventfully with a truncal lesion of the sciatic nerve at the thigh. The fourth who was delivered by caesarean section for alteration of the monitoring presented a severe strangulation of the arm by the umbilical cord with palsy of the radial and ulnar nerve. The palsies recovered spontaneously and the sequelae are mostly due to the muscle necrosis. Congenital dysfunction of major peripheral nerves have been described as a complication of congenital constriction band syndrome, in association with subcutaneous fat necrosis, neonatal gangrene or aplasia cutis congenita. Intrauterine compression of a limb may be favoured by decreased foetal activity, by spontaneous rupture of the amniotic sac, particularly if there is a delay in delivery and by abnormal uterine activity during labour. Our three first cases confirm that the compression may arise before the labour. The fourth demonstrates that umbilical cord strangulation may lead to anoxia of the foetus together with compression of the limb.
