apply pressure over radial head and supinate the forearm
pain relief immediate
return of function is evident quickly

Q

Barlow?

A

adduct the flexed hip and gently push the thigh posterior to try and disloacte the femoral head

pos: hip is felt to side out the acetabulum

54
Q

Ortolani?

A

lift the greater trochanter whild abducint the hip

palpable clunk signifies femoral head slipping into the hip socket

55
Q

Developmental dysplasia of the hip?

A

asymmetry of skin folds of thighs and buttocks

56
Q

Imaging Developmental dysplasia of the hip?

A

hip ultraosound under 4 mths

hip xray if 4-5 mths of age

57
Q

Treat Developmental dysplasia of the hip?

A

palvik harness:keeps hips flexed and abducted

doesn’t work= closed reduction and immbolization in a spica cast

limp

pain in groin, knee, thigh

Q

Legg-Calve-Perthes Disease long term?

A

self limited
typically lasts 1-2 years
long term prognosis- most patients are active, pain free, and have a good ROM

62
Q

Legg-Calve-Perthes Disease treatment?

A

goal is to create a spherical, well covered femoral head with ROM close to normal
Mainstay: non-operative
more severe cases

surgical pinning

Q

Phyiscal exam Osgood-schlatter disease?

A

point tenderness over the tibial tubercle and patellar tendon

72
Q

Radiographs Osgood-schlatter disease?

A

soft tissue swelling around the tibia apophysis

fragmentary ossification of the tibial tubercle may be noted

73
Q

Treatment Osgood-schlatter disease?

A

rest, restrict activities, knee immobilize occasionally, NSAIDs for pain relief, complete resolution may require 12-24 months

74
Q

Clubfoot deformity?

A

Talipes equinovarus
apparent after birth
more common in males
unilateral of bilateral

75
Q

Clubfoot deformity positional?

A

held in a deformed position in utero

flexible on exam

76
Q

Clubfoot deformity congenital?

A

spectrum of severity

those associated with neurovascular causes or syndromes are more rigid and difficult to treat

77
Q

Clubfoot deformity physical exam?

A

watch for musculoskeletal or neuromuscular problems

calf atrophy

78
Q

xray clubfoot?

A

may not be necessary

79
Q

Treat Clubfoot deformity?

A

manipulation with serial casting

surgical realignment if nonoperative measures have failed or for clubfeet that are rigid

80
Q

Metatarsus adductus?

A

adduction of the forefront relative to the hindfoot
metatarsals are deviated medially
most likely form intrauterine molding
no pathologic changes in structures of foot
should be distinguished from congenital clubfoot
may be passively correctable by examiner

81
Q

xray Metatarsus adductus?

A

abnormal deviation of metatarsals medially

no other osseous abnormality

82
Q

treatment Metatarsus adductus?

A

ranges from passive manipulation to casting to surgery

should be started prior to walking age
