Pediatric orthopedic conditions Flashcards
Torsional conditions - toeing in/out - foot progression angle is the angle made by the foot with respect to
a straight line plotted in the direction the child is walking
Torsional conditions - toeing in/out - foot progression angle can be normal in children with combined torsional deformity - (+) sign denotes? (-) sign denotes
+ sign denotes out toeing angle
- sign denotes in toeing angle
Torsional conditions - toeing in/out - thigh foot angle is the angle between
axis of foot and axis of thigh measured with child prone and knees at 90
The angle describes the degrees of tibial torsion
Torsional conditions - toeing in/out - toeing in (pigeon toed) is common in
W sitting and is caused by three types of deformities
Torsional conditions - toeing in/out - toeing in is caused by what 3 types of defomities
metatarsus adductus
internal tibial torsion
increased femoral anteversion
Torsional conditions - toeing in/out - most common congenital foot deformity
metatarsus adductus
Torsional conditions - toeing in/out - matatarsus adductus greater occurance in
females on left side
Torsional conditions - toeing in/out - most common cause for metatarsus adductus
intrauterine packing
Torsional conditions - toeing in/out - metatarsus adductus - types
Rigid
Flexible
Torsional conditions - toeing in/out - metatarsus adductus - Rigid form results in
medial subluxation of tarsometatarsal joints
Hindfoot slightly in valgus with navicular lateral to head of talus
Torsional conditions - toeing in/out - matatarsus adductus - flexible form is observed as
adduction of all five metatarsals at the tarsometatarsal joints
Torsional conditions - toeing in/out - metatarsus adductus - flexible form treatment
85-90% identified at birth will resolve without treatment in 1 year
Torsional conditions - toeing in/out - most common cause of toeing in
internal tibial torsion
Torsional conditions - toeing in/out - increased femoral anteversion
Normal is 10-15 degrees
Considered excessive if angle is greater than 25-30 degrees
Torsional conditions - toeing in/out - toeing out is how common? can be caused by what?
less common
can be caused by femoral retroversion, external tibial torsion, flat feet
Torsional conditions - toeing in/out - toeing out - retroversion defined as
less than 10 degrees
Talipes equinovarus (clubfoot) - etiology
postural from intrauterine malposition
Talipes equinovarus (clubfoot) - observation
PF, adducted, and inverted foot
Talipes equinovarus is defined as
PF at talocrural joint
Inversion at subtalar, talocalcaneal, talonavicular, and calcaneocuboid joints
Supination at midtarsal joints
Angular conditions - genu valgum
excessive lateral tibial torsion, referred to as knock knees
Excessive lateral patellar positioning
Angular conditions - genu varum
excessive medial tibial torsion
referred to as bowlegs
Genu varum is normal in
newborns and infants
Maximal varum occurs at what age
6 to 12 months
Lower limbs straighten with a zero tibiofemoral angle by what age
18 to 24 months
Knees gradually drift into valgus and is max at what age
3 to 4 years with avg lateral tibiofemoral angle of 12
Genu valgum corrects by age
7 to adult alignment
8 in females and 7 in males
Hip dysplagia - who is at higher risk
females breeched position family hx low levels of amniotic fluid swaddling infant too tightly
Hip dysplagia - gold standard tx
Pavlik harness - 95% success in those under 6 months
Transient synovitis in children - etiology
acute onset of sudden hip pain in children ages 3 to 10
Transient inflammation of synovium of the hip
Transient synovitis in children - s/s
unilateral hip or groin pain less common medial thigh or knee pain crying at night antalgic limp pain not common recent hx of upper resp. infection
Leg Calve Perthes disease - etiology
blood supply interrupted to femoral head
onset age 2 to 13 years
4x greater incidence in boys
Leg Calve Perthes disease - clinical s/s
Psoatic lump from weakness of psoas mm - moves in ER, flex, add
gradual onset of aching pain at hip, thigh, and knee
AROm limited in abd and ext
Slipped capital femoral epiphysis - etiology
most common hip disorder observed in adolescents of unknown etiology
Slipped capital femoral epiphysis - what is it
femoral head is displaced post and inf in relation to femoral neck and within confines of acetabulum
Slipped capital femoral epiphysis - onset in males is? females?
Males 10-17 yrs with avg being 13
Females 8-15 yrs with avg 11
2x greater incidence in males
Slipped capital femoral epiphysis - dx based on clinical exam
AROM restricted in abd, flex, IR
Pt describes pain as vague at knee, thigh, hip
Chronic - might see trendelenburg gait
Tendon lengthening conditions - osgood schlatter disease - etiology
mechanical dysfunction resulting in traction apophysitis of tibial tubercle ate the patellar tendon insertion
Tendon lengthening conditions - Sever’s disease (calcaneal apophysis) - etiology
most common cause of heel pain in growing children - occurs before or during peak growth spurt
Caused by repetitive microtrauma due to inc traction by achilles tendon at insertion
Tendon lengthening conditions - sinding larsen johannsons disease - etiology
traction apophysitis at patella-patellar tendon junction, overuse from repeated stresses, can occur after significant growth spurt and/or increase in activity
Growing pains - etiology
unknown but could be due to muscular fatigue, poor posture, stress
Growing pains - effects what ages
most likley between 3 to 5 and 8 to 11
Osteochondritis dissecans - etiology
adolescents between ages of 12 and 15 yrs
Most common cause is a separation of articular cartilage from underlying bone
Osteochondral bone fragment becomes detached and forms loose body in joint
Panners disease - etiology
localized avascular necrosis of capitelum leading to loss of subchondral bone with fissuring and softening of articular surfaces of radiocapitellar joint
Unknown etiology - usually ages 10 or younger
Scoliosis - treatment
conservative if less than 25 degrees
bracing if between 25 and 45
surgery if over 45 degrees
Ped planus (flat foot) - normal in who
infant and toddler feet and develop around 2 to 3 years
Congenital muscular torticollis - observation
side bending toward and rotation away from affected SCM
Spasmodic torticollis - is what
movement disorder with CNS pathology
Plagiocephaly (flat head syndrome) - etiology
flat spot on back or side of head as skull is soft and malleable
No lasting harmful effects on infant
Arthrogryposis multiplex congenita - etiology
congenital deformity of skeleton and soft tissues characterized by limitation in joint motion and sausage like appearance of limbs
Nonpregressive contractures
Intelligence develops normally
Osetogenesis imperfecta - etiology
inherited transmitted by autosomal dominant gene
Characterized by abnormal collagen synthesis leading to imbalance between boen deposition and reabsoroprtion
Leads to fractures and deformity of WB bones
Spondylolistheiss - etiology
congenitally defective pars interartciularis
lysis - fracture
listhesis - anterior slippage
Spondylolisthesis - grades
graded from grade 1 (25% slippage) to a grade 4 (100% slippage)
