Pediatric MSK problems Flashcards
In-toeing/out-toeing torsion what should you look for/ask
- w-sitting is typical but with abnormalities it can exacerbate them
- history: want to know prenatal history, delivery etc
- age questions: when did you notice this and how is it affecting them
- family history: was someone else having issues with toeing in or out
- sleeping and sitting positions: ex: stomach sleeping can cause ER at hips
Examination of pediatric MSK problems
- observe child walking especially when they do not know they are being watched
- supported stance foot progression angle (FPA): walking on a floor with a line to look at if they are diverting in or out form the line
Contributing factors to in-toeing
- femoral anteversion
- internal tibial torsion
- metatarsus adductus
- w-sitting
In-toeing clinical features
- tripping and falling often is a presentation
- often noticed around 2 years old
- internal rotation:
1. 70-80 degrees: mild FA
2. 80-90 degrees: moderate FA
3. 90 degrees= severe FA
Internal Tibial Torsion- how can it be corrected in children?
- children may have to wear bracing that looks like a snowboard
- this will help turn out the tibia
- some braces are made to allow for more mobility
Metatarsus adductus or varus causes
- infant foot
- caused by intrauterine pressure, osseous abnormality and abnormal muscle attachments
- some genetic component
- contractures of soft tissue around tarsometatarsal joints
Out Toeing
- rare in infants
- detected when held upright
- should not go beyond 2 years of life
causes of out-toeing
- slipped capital femoral epiphysis
- legg-calve-perthes disease (LCP)
- idiopathic osteonecrosis of the hip
- neuromuscular disorders
External tibial torsion
- worsens over time
- late childhood and adolescence is when they are diagnosed
- rotational deformity
- requires surgery
- derotational tibial osteotomy
- will complain of pain
- genu varum
- concerning if present after age 4 years
- if anterolateral bow of tibia = X-rays needed
- at risk of fractures the first year of life
- most common cause blount disease
- can be hereditary
genu valgus
- many are overweight
- gait patterns is circumduction
- angular deformity, anterior and medial knee pain are common
Talipes varus vs talipes valgus
- walks on the outter portion of the foot
- walks on the medial portion of the foot
talipes equinus vs talipes calcaneus
- in more plantar flexion
- ankle in more dorsiflexion
what is clubfoot/metatarsus adductus
- congenital talipes equinovarus
- 1-2/1000 births
- different grades of severity
Clubfoot/metatarsus adductus: treatment/goal of treatmetn
- serial casting birth up to 9 years to get into typical position using ponsetti method
- may need surgery if casting does not work
- goals:
1. full loading
2. plantigrade position
3. wear normal shoes
Post ponsetti method improvments
- ambulation improves
- development of milestones improves
- motor learning (if left in this position they will develop bad movement patterns)
- balance
- strenght
- functional movement skills
Surgical correction of alignment abnormalities- what indicates it/what do they do?
- timing: so important generally earlier if casting is no working
- age dependent usually infants
- severity
- soft tissue release
- muscle transfer if muscles are not functioning
Cavus foot
- abnormal elevation of the longitudinal arch of the foot
- forefoot equinus
- hindfoot calcaneus or varus deformity
cavus foot and associated neurologic consitions
- 2/3rds have CP, spinal cord or charcot-marie-tooth disease (an immune disease that affects joints and causes them to maintain a contracted position - similar to arthritis)
- surgical procedures of cavus foot
- soft tissue releases (plantar fascia)
- tendon transfer (especially with nerve damage)
- ostotomies: metatarsal, midfoot, or calcaneal osteotomies
- fusions: triple arthrodesis used as a last resort or children who are immobile to reduce risk of fractures
when are feet normally flat until
- 2 years and sometimes 6 years
- there are flexibilty flatfoot and rigid flatfeet
flexibile flatfeet
- signs
- treatment
- what occurs at subtalar and forefoot
- most common pediatric foot “deformity”
- uneven medial shoe wear down
- orthotics can improve uneven shoe wear
- tightness of the gastrocsoleus muscle
- higher incidence of flatfeet in blacks
- subtalar joint is DF, ER,
- midfoot: abducted
forefoot is supinated in relation to hindfoot
Test for flexibility in flat feet
- windlass test or jack’s toes raising test
- looks at how flexible the plantar fascia is
- can be done in sitting or standing
- when the foot is flat on the ground you raise the big toe and watch if the arch height increases or decreases
Calcaneovalgus:
- commonly seen
- treatments
- commonly seen with CP, spina bifida, idiopathic flatfoot
- treatments:
1. stretching
2. ankle foot orthosis or supramaleolar orthosis
3. sometimes surgery
4. serial casting
rocker bottom foot
- less commone
- surgery is needed
- similar to calcaneovalgus
- sometimes with mild cases splinting is needed
Knee injuries: adults in relation to kids
- lower incidence in children than in adults
- knee injuries are the most common cause of permanent disability in adults
Overuse injuries
- 50% of injuries in children are overuse
- stress fractures
- joint injuries
- muscle and tendon injuries
overuse injuries are related to
- increased participation in sports
- increase in specialization
- complex, longer training at younger ages
Injury prevention - pre participation examination
- vital sings, height, weight
- orthopedic exam
- flexibility and strength assessment
- body composition
- speed, agility, power, balance, endurance
Prevention of injuries
- improve muscle reaction time and proprioception
- muscle strengthening as a daily training routine
- physical examination
- diagnosis of muscular imbalances of functional restrictions
- proper use of protective equipment
- adequate field and surface playing conditions
- changes of rules in sports
training programs
- individualized based on age and development
- energy training aerobic and anaerobic
- resistance
- speed
- nutrition and hydration
Risk factors for injury
- training errors
- muscle tendon imbalance
- anatomical malalignment
- improper foot wear (suggested to replace every 3 months)
- playing surface
- disease
- growth-related factors
Scoliosis types
- idiopathic
- congenital
- neuromuscular
- degenerative
Scoliosis
- lateral deviation of spine from is central axis greater than 10º
Structural scoliosis
- person actually has a physical curve
functional scoliosis
- person appears to have a curve but caused by another condition such as a different in leg length or muscle spasm
- spine will compensate to maintain symmetry
What can happen with scoliosis
- can cause trunk imbalances that increase the likelihood for muscle spasms and others leading to pain
How does scoliosis progress
- many children is can progress quickly and become deadly
- accelerates during growth spurts
- estimated that it increases about 0.82º per year
adolescent scoliosis is the most common 11-18 years
Kyphosis types
- congenital
- postural
- scheuermann’s kyphosis
Congenital kyphosis
- babies born with kyphosis often need surgery at a young age
postural kyphosis
- due to poor posture which is increased in girls
- shows up in teens
- if not self-corrected by standing up straight tan PT and bracing is needed for curves create than 65º
Scheuermann’s kyphosis
- spinal bones grow in an abnormal wedged fashion
- usually in teens,
- physical therapy, medication, bracing and surgery are needed
Halo traction
- used for scoliosis and kyphosis
- upward pulling of the head and spine using a weighted pull system to elongate and straighten the spin
- stay in the hospital lasts nearly 3 months
- not as painful as it looks and you must watch for infections
backpack safety: what to look out for
- muscle strain can be caused by improper backpack use
- numbness/tingling
- tripping
- they don’t cause scoliosis
- should not be carrying more than 15% of body weight in the backpack
- put the heaviest items low and near the center of the back
Growth related injury risk factors
- affects the growth plate
- osteochondritis
- apophysitis (inflammation of apophysis)
- severs
- osgood-schlatters diseases
- musculotendinous junction
apophysis
- secondary ossification center which acts as an insertion site for tendons
Types of injuries in bone
- stress fracture
- epiphyseal plate fracture
- shaft fracture (more common in adults
Salter-harris classification of growth plate fractures
- type 1: Straight across
- type 2: Above
- type 3: Lowe or beLow
