week 3 assessment and management of MSK cond. in infancy Flashcards
1. Outline the musculoskeletal development seen in infants and children 2. Describe the changes seen in lower limb alignment in infants 3. Outline musculoskeletal conditions seen in infancy 4. Outline some current physiotherapy intervention strategies for infants with musculoskeletal conditions
Features at birth
- kyphosis from Cx to sacrum
- Hip flexion/ Lateral rotation
- IR of tibia
- Equinus position of feet (upward)
- varied limitations of hip, knee, elbow extension
Outline the musculoskeletal
development seen in infants and
children (muscle and bone)
*response to physical demands.
Muscle:
- tension leads to longitudinal growth
- rapid fetal growth stretches muscles and stimulates it to grow longer and at the same rate as bone
Bone:
- after birth, long bones grow in length at epiphyseal plate
- cartilaginous plate stages: Proliferates> chondrocytes> convert to bone> ossification
Describe the changes seen in
lower limb alignment in infants
normal changes:
- newborn: genu varum
- 1-2 years starts to straighten out
2-4 years can develop genu valgum, some males genu varum
these are normal
Neonatal fractures : when are they common and what is the Rx, how long ?
- common during delivery (shoulder dystonia - shoulder gets caught during birth)
- Rx = immobilisation (eg. in a tubigrip)
- healed within 2 weeks
The normal foot :
describe features +
how infant differs from adults (structure and ROM)
-26 bones
Most cartilagenous at birth:
- hindfoot = calcaneus and talus
- midfoot - navicular, cuboid, cuneiform bones
- forefoot = metatarsals and phalanges
Infant ROM> adult
Foot deformities in infancy
talipes or pes = foot
- equinus = plantar flexion
- varus = turns in
- valgus = turns out
- pes planus = flat feet
- pes cavus - high arch
Clubfoot
definition, features and Outcome measure scoring
a complex congentical contractual malalignment of the foot and ankle
features: C: cavus A: adductus V: carus E: equinus
(+ wasted calf muscles , empty heal)
Pirani Score
Management of Clubfoot (what is the gold standard, what are the results)
A conservative method of casting and splinting, with minimal surgery is now seen as the gold standard Rx of clubfoot
Results :
- good long term outcomes
- low rates of relapse
- min requirements for extensive corrective surgery
Describe the Pirani Score
A. Curvature of lateral border B. Medial crease C. Lateral head of talus D. Posterior crease E. Emptiness of heel
Postural foot deformities
- talipes equinovarus
- overriding toes
- talipes calcaneovalgus
Management of postural foot deformities
- careful Ax to rule out serious causes (eg. congenital vertical talus, neurological conditions)
- “unpack the baby”
- gentle stretches if needed
- reassure parents
- monitor resolution
- Check for DDH and head preference
- encourage tummy playtime
Congenital Vertical talus
- talar head prominant medially
- sole is convex
- forefoot abducted and DF’d
- hindfoot is in equinovalgus
- rocker bottom foot
- often associated with other abnormalities (meningomyelocoele)
Myelomeningocoele associated foot deformity
and management
a birth defect that occurs in the early weeks of fetal development. It is the most common and most serious type of spina bifida
The paralysis can lead to deformities of the legs, feet, and back.
(management can include serial casting)
Developmental Dysplasia of the Hip (DDH) (what is it?/ aetiology? presentation?)
- abnormal development of the hip joint
Aetiology:
- intrauterine positioning resulting in a stretched posterior capsule
- neurological condition
The hip presents as dislocated, dislocatable or subluxed
Management of DDH
- all babies screened at birth
(Ortolani or Barlow) - Diagnosis confirmed with US
- Irremovable splint fitted on day 1 if possible
-other splints available (Von Rosen Splint- only 1.2% failure rate)
Physiotherapy management of DDH
- understanding of DDH May suspect the condition if: - limb length discrepancy - assymetry of movement - limited ROM of hip ABd - asymmetrical thigh folds - limping of waddling gait (toddler) *may be associated with torticollis*
Immediate referral or orthopaedic review
Torticollis ( what is it secondary to?)
- skeletal
- neurological
- muscular (SCM, muscular tightness, postural)
- visual disorder
What is congenital muscular torticollis (CMT) ?
Sand S’s?
-shortening of the SCM + tumour
SandS’s:
- tilt head toward affected muscle
- rotated toward contralateral side
-upper traps can also be involved and contribute to neck deformity
What is CMT prevalence and cause?
- prevalence varies (0.3%-2.0%)
causes = unknown
What happens if toricollis persists ?
craniofacial deformities or plagiocephaly can occur
Torticollis - things to rule out in subjective/objective
- History - VIP: rule out ==
- Reflux
- Pharyngeal abscess
- Cervical rib
- CTEV, DDH
- Older child (visual and/or hearing)
deformational plagiocephaly (what it is, what are signs?)
- postural condition
- oblique, mishapen, parallelogram head
- repeated external pressure to the head as a result of being in the one position for extended lengths of time (eg. sleeping)
- flattening of occipital bone
- more prominent head and cheek on that side
- ear pushed forward compared with the other
Craniosynostosis (what is it? what imaging can be used to DDx between plagiocephaly?)
- skull asymmetry
- premature fusion of one or more skull sutures
- x-rays +/- CT scans
Prevention and management of plagiocephaly ?
-professional Ax and advice (infant positioning is associated with early head orientation and plagiocephaly) parent often reports assymetry during wakening and sleep
- from birth: alternate the head position when sleeping
- encourage active head control strategies (prone, sideways lift, etc. )
- if no improvement after 2 sessions = medical review to rule out pathology (craniosynostosis, Cx rib)
-do NOT refer for helmet unless specialist review has occured
