Q

Which babies should have ultrasound scan to check for hip dysplasia?

(PS: USS is only good for <6months due to insufficient ossification of hip. >6months will need hip radiograph)

A
  1. all babies that were breech at any point from 36 weeks (even if not breech by time of delivery)
  2. babies born before 36 weeks who had breech presentation
  3. all babies with a first degree relative with a hip problem in early life
  4. Multiple pregnancy - ie if one of a pair of twins is breech, both should be screened

Q

How do you manage a baby with DDH (developmental dysplasia of hip)?

A

Nothing usually as the unstable hip should normally stabilise by 3-6 weeks of age

If less than 4 or 5 months, Pavlik harness (dynamic flexion-abduction orthosis)

If older - may require surgery.

THis is not an inherited disease! patient often improves as they grow.

PS: this condition has many similarities with Treacher-Collins syndrome. One of the key differences is that Treacher-Collins syndrome is autosomal dominant so there is usually a family history of similar problems.

- autosomal dominant

autosomal recessive - usually metabolic diseases (exceptions: structural causes such as ataxia telangiectasia and Freiderich’s ataxia)

autosomal dominant - usually structural diseases (exceptions: Gilbert’s, hyperlipidaemia type II)

HERE ARE THE ANOMALIES:
Some ‘metabolic’ conditions : Hunter’s and G6PD are X-linked recessive whilst hyperlipidaemia type II and hypokalaemic periodic paralysis are autosomal dominant

Transient synovitis VS septic arthritis in child

(Hint: presenting complaint differences)

A

hip pain, limp and recent infective/autoimmune illness : transient synovitis
- ALSO, don’t need to aspirate the joint

if child has full-raging fever - think septic arthritis! (there may be mild fever in transient synovitis)
- ALSO, aspirate the joint to rule this out!

Q

what is Kocher’s criteria?

A

Kocher’s criteria is used to assess the probability of septic arthritis in children using 4 parameters:
Non-weight bearing - 1 point
Fever >38.5ºC - 1 point
WCC >12 * 109/L - 1 point
ESR >40mm/hr

The probabilities are calculated thus:
0 points = very low risk
1 point = 3% probability of septic arthritis
2 points = 40% probability of septic arthritis
3 points = 93% probability of septic arthritis
4 points = 99% probability of septic arthritis
