F. Shallow, poorly developed acetabulum

Question 40

An otherwise healthy 6-month-old girl is brought to the physician because of a hemangioma on her neck that has been enlarging since 6 weeks of age.

Answer 40

Observation

Question 41

You are called to evaluate a full-term infant. The infant’s mother expressed concern about her newborn’s arm shortly after delivery. The mother’s prenatal history is notable for gestational diabetes mellitus that was well-controlled with diet. . The infant’s size was appropriate for gestational age. On physical exam, pupils are equal round and reactive to light. There is limited movement of her right arm. Her upper arm is adducted and internally rotated, her elbow is extended, forearm pronated, and wrist and fingers flexed. Biceps and Moro reflexes were absent on the right side. No sensory loss was noted. There is no crepitus over the collarbones. The other arm was normal and the rest of the physical examination was unremarkable.

This pattern of injury is caused by injury to which structures?

A. C5-C7
 B. C5-C6
 C. C5-T1
 D. C8-T1
 E. Radial nerve

Answer 41

C5- C7

Question 42

What is the nerve root injury associated with Erbs Palsy

Answer 42

C5 - C7
The arm is adducted with the forearm extended, internally rotated, and pronated, generating the classic “waiter’s tip” appearance. The biceps and Moro reflexes are absent on the affected side and sensory function usually is preserved. This infant also has wrist and finger weakness suggesting injury to C7.
