Ortho/neuros Flashcards
When can infant roll prone to supine
4 months
When can infant sit using tripod position
6 months
When do infants begin creeping
9 months
9 rhymes with mine - creeps be thinking, “you’re mine”
When do infants stand without support momentarily
12 months (cut off for when typically pathological 18 months)
Polydactyly v. syndactyly
Too many fingers toes
Some of them are fused
True or false; newborns under 2 months typically have “twitching” movements - normal variant
false; movements should always be symmetric with no twitching (newborns will naturally have flexed position though)
What is the “Gower sign” What is it suggestive of?
Child rises from sitting by placing hands on legs and pushing way up (crawl up their legs)
Muscular dystrophy
Early signs of muscular dystrophy
clumsiness
difficulty climbing stairs
frequent falls
Muscle atrophy & progressive weakness
pseudohypertrophy from fatty infiltration
Gower sign
muscular dystrophy
Barlow’s and Ortolani’s test are both looking for what?
Hip dysplasia (not as reliable >3 months as muscles and ligaments strengthen)
3 causes of hip dysplasia
Acetabular dysplasia (delayed ossification of acetabulum)
Subluxation
Dislocation
Of the 3 causes of hip dysplasia - which is the only one to cause loss of contact of femoral head with acetabular capsule
dislocation
What is Allis sign looking for?
DDx hip dislocation v. shortened femur
A positive would be one knee appearing lower than the other
What is the Barlow maneuver? How is it different than Ortolani (considering they’re both looking for same thing)
Barlow you ADduct thigh and press down
Ortolani you ABduct thigh
Both are positive if feel “palpable clunk”
True or false; hip dysplasia is MC in females
true - commonly associated with intrauterine constraint (breech)
What is MC brachial plexus injury due to birth trauma
Erb’s palsy (C5/C6) - large infant/shoulder dystocia
Causes paralyzed arm “waiter’s tip” sign
True or false; an infant with erb’s palsy (C5/C6) will have absent Moro, biceps, radial, and grasp reflexes
false; all are absent EXCEPT grasp
What is one of the MC missed findings on infants (hint due to birth trauma)
Fractured clavicle (eventually lump or callus forms)
True or false; common for infants to present with pes planus, metatarsus adductus or tibial torsion
true
True or false; pes planus (flat feet) is normal until 3 years of age when longitudinal arch should form
true
What is the MC congenital foot deformity
Metatarsus adductus (forefoot adduction)
True or false; metatarsus adductus can be seen on plain film
true tarsometatarsal joints angled medial
What is tibial torsion - what is it caused by
slight varus curvature of the tibia
Related to fetal positioning
Expected to resolved afters months/years of weight bearing
How do you asses for tibial torsion
Lay patient prone, flex knee, one thumb on lateral malleolous, other thumb on lateral knee - if thumbs don’t line up = + test
