3 yo male in ER with pain to right elbow. Won’t allow touch elbow, father denies kid falling, swelling, fever or chills. Child is in good health and vaccines are up to date. The father states that before this they were at the park and the father was swinging the boy around. What is likely cause of the pain and treatment?
Treatment not in exam
- Nurse maids elbow

- Most common in kids due to sudden pulling, falling and arm twisting, the annular ligament slips out of radial head
Hyperpronation better success rates
Supinate and flex also works to fix

What is dupuytrens contracture?
- Fibrosis of plmar fascia which causes progressive stiffening of joint and inablity to fully extend the finger
- Cause is idiopathic thiekening of palmar fascia due to fibroelastic proliferation and collagen deposition
- Classically presents:
- white men
- Thickening on palmar surface
- Pain or no pain
- cord like structrure and flexeddigit with palpable cord
