Two cases of neonates with Erb’s palsy, reflecting light upon the recovery times of the injury.
Erb’s palsy or the waiter’s tip hand is the result of injury to nerve roots, C5 and C6, at the point where C5 and C6 unite to form the upper trunk of the brachial plexus. لعبة الروليت مجانا However, around 50% of the patients may also have C7 affected. Usually, the affected babies immediately diagnosed due to the arms hanging limply from the shoulder with internal rotation of the forearm plus wrist and finger flexion.
Approximately, two-thirds of the cases are in babies with shoulder dystocia during labour. However, other contributing factors include a very rapid or a prolonged second stage of labour, multiparous women, and obstetrical manoeuvres (controversial).
Case 1: Erb’s Palsy with complete, spontaneous, and rapid recovery
A baby boy was born to a 29-year-old woman via assisted vaginal delivery with artificial rupture of membranes. The fluid was meconium stained. The obstetricians used low-forceps, however, the delivery as difficult due to shoulder dystocia. The baby weighed 4398 g. Baby’s APGAR scores were 4 and 8 at 1 min and 5 min, respectively. لعبة البلاك جاك Right after birth, the obstetricians could immediately observe the right Erb’s palsy with no deltoid and weak bicep function.
By the age of 5 weeks, the baby had shown significant improvement. He regained spontaneous deltoid contraction (90° of abduction). روليت عربي Additionally, his biceps were able to flex his arm against gravity. Wrist and finger extensors were both normal.
At the 3-month follow-up, the baby showed complete recovery.
Case 2: Waiter’s Tip hand with slow recovery
A nulliparous woman gave birth to a baby weighing 4200 g. Due to decreased foetal tone, the doctors had to induced labour. They used low vacuum suction for assisting the vaginal delivery. The obstetrician also had to apply suprapubic pressure, McRoberts manoeuvre, and a ‘corkscrew’ manoeuvre due to moderate shoulder dystocia. At 1 and 5 minutes, the APGAR scores were 9 and 9. Immediately after birth, the doctors could notice severe right Erb’s palsy with little wrist extension and no bicep or deltoid function.
By the age of 6 weeks, the baby had not regained bicep or deltoid function; however, the brachioradialis and triceps were normal. Moro reflex demonstrated supraspinatus contraction only, with a few degrees of abduction.
There were hopes of improvement, however, a plastic surgery assessment was scheduled in case if there would be no improvement by the age of 5 months.
