lecture 10 [musculoskeletal + neuromuscular] Flashcards
what are the acquired skeletal defects?
(6)
- Legg-Calve-Perthes
- slipped capital femoral epiphysis(SCFE)
- kyphosis
- lordosis
- scoliosis
- spinal neuromuscular atrophy
what is Legg-Calve-Perthes disease?
asceptic necrosis of the femoral head that can either be unilateral or bilateral
what are the symptoms of LCP?
(6)
- painless limping
- hip stiffness
- limited ROM
- hip, thigh, & knee pain
- shortened affected leg
- muscle wasting
what are the treatment goals for LCP?
(4)
- eliminate hip irritability
- maintain ROM
- prevent bone collapse
- ensure well-rounded femoral head
what are the primary therapeutic measures for LCP?
- abduction brace/ cast
- traction
what is slipped capital femoral epiphysis (SCFE)?
spontaneous displacement of the proximal femoral epiphysis that develops shortly before onset of puberty or accelerated growth
SCFE is more commonly seen in boys & obese children
true
which conditions are associated with SCFE?
- GH therapy
- endocrine disorders
- renal osteodystrophy
- radiotherapy
what are the primary treatments for SCFE?
- non-weight bearing activity
- surgery
SCFE must be diagnosed early
true
what is kyphosis?
convex curvature of the thoracic spine
kyphosis is usually a secondary condition to other diseases like:
- TB
- chronic arthritis
- compression fractures
how is kyphosis treated?
- shoulder/ abdomen exercises
- bracing
what is lordosis?
cervical or lumbar curvature of the spine
lordosis is often associated with which other conditions?
- hip contractures
- scoliosis
- obesity
- hip dysplasia
- SCFE
what is scoliosis?
lateral curvature of the spine, possible spinal rotation & thoracic hypokyphosis
what is the “gold standard” treatment for scoliosis?
bracing
what are the different types of braces for scoliosis?
(3)
- Boston
- Milwaukee
- Charleston
what are the congenital muscular disorders?
- spinal muscular atrophies
- Duchenne’s muscular dystrophy
Duchenne’s muscular dystrophy is the most severe form of muscular dystrophy
true
why are males more affected with Duchenne’s?
it is primarily an x-linked genetic disorder
what are the diagnostic procedures for Duchenne’s?
- muscle biopsy
- blood polymerase chain reaction to detect dystrophin gene mutation
- blood creatine phosphokinase (elevated)
there is no treatment for Duchenne’s; and families only need to be prepared for impending cardiac & respiratory difficulties along w/ mental retardation
true
what are the manifestations of Duchenne’s?
(5)
- Gowers sign
- waddling
- difficulty rising to positions
- progressive muscle atrophy
- loss of ability to walk by 12yrs
what are the congenital skeletal defects?
(5)
- hip dysplasia
- club foot
- genu varum
- genu valgum
- osteogenesis imperfecta
what are the expected diagnostic signs of hip dysplasia?
(6)
- Ortolani sign (hip is reduced w/ abduction)
- Galeazzi/ Allis sign (uneven knee levels)
- Barlow sign (hip dislocates by adduction)
- Trendelenberg sign w/ lordosis (tilted hips with standing on one foot)
- U/S or x-ray
when is an ultrasound appropriate for hip dysplasia?
2 weeks old
when is an x-ray appropriate to diagnose hip dysplasia?
older than 4mos
what are the treatments for hip dysplasia?
- Pavlik harness
- Bryant traction
- Hip spica cast
- surgical reduction
at what age is the Pavlik harness appropriate?
newborn to 6 months
what is a Pavlik harness?
a chest harness that abducts legs
what is the treatment for hip dysplasia WITH adduction contracture?
- Bryant traction
- Hip spica cast
when is surgical reduction appropriate for a child with hip dysplasia?
when they are 6 months to 2 years old
what is club foot?
a complex deformity of the ankle & foot that is sometimes associated with cerebral palsy & spina bifida
what are the categories of club foot?
- positional
- syndromic
- congenital
what causes positional clubfoot?
intrauterine crowding
what is syndromic clubfoot?
a category of the disorder that occurs with other syndromes
what are the therapeutic procedures for club foot?
casting
how are the series of casts implemented for clubfoot?
applied every 2-3 days for up to 3 weeks, then 1-2 week intervals
genu varum
genu valgum
what is osteogenesis imperfecta?
an inherited connective tissue disorder that results in bone fractures along w/ restricted growth
“brittle bone disease”
what are the clinical manifestations of osteogenesis imperfecta?
- multiple bone fractures
- blue sclera
- early hearing loss
- hypoplastic discolored teeth
what is the treatment for osteogenesis imperfecta?
pamidronate IV with biphosphate
