MSK Injuries in Children and Adolescents Flashcards
Anatomical differences vs adults
Epiphyseal plates and its junctions Growth spurts Bone malleability Apophysites Articular cartilage Muscle development Frequency and variety of sports
Relevance of epiphysis
Epiphyseal plates in growing skeleton
site of weakness not seen in adults; susceptible to sheer forces
Relevance of metaphysis
Softer part of bone
bone malleability => absorbs greater energy => less brittle
more susceptible to fractures
most common = Greenstick
Relevance of diaphysis
main section of long bone made up of cortical bone
Growth plates and Growth spurts
Growth plates = between epiphyses and metaphysis - fracture lines
Growth spurts are a result of the changes in the balance of bone and muscle causing altered biomechanics, co-ordination and energy levels
Apophysites (function and relevance)
Boney attachment sites of muscle tendon
in maturing skeleton => area of weakness because bone is softer
Apophysites examples of the pelvis
ASIS - sartorius
AIIS - rectus femoris
PUBIC SYMPHYSIS - rectus abdominus via ing ligament
ILIAC CREST - gluteals, Tensor fascia latae
ISCHIAL TUBEROSITY - adductor magnus, biceps femoris, semitendinosus, semimembranosus
GREATER TROCHANTER - gluteus medius and minimus
LESSER TROCHANTER - psoas/iliacus
Features of articular cartilage in kids
thicker and greater ability to remodel
thus more likely to get osteochondritis diseccans; blood supply more easily modified
Factors of joint stability
muscle development
ligament laxity
core stability
Principles of Management of Sporting child
Manage physiological processes
identify causes and emphasise rehabilitation based on this
address biomechanics
do not forget
- inflammatory conditions and other medical conditions
- cardiovascular changes
- nutrition
- psychosocial factors
- environmental factors; greater body SA
- autonomy, beneficence, confidentiality, do not harm, equity
- player development
Growth plate fractures
Salter harris classification (5 types)
can be complicated
Rx depends on type
healing depends on severity, age, which growth plate and type
Salter Harris Classification
Type I - straight through growth plate
Type II - extends through metaphysis (chip)
Type III - extends through epiphysis (T shaped)
Type IV - through both epiphysis and metaphysis
Type V - compression fracture
Greenstick fracture
one side broken and other is bent
reduced
casted for 6 wks
usually in metaphysis
Buckle fracture
‘torus’ fracture
FOOSH - fallen on outstretched hand
incomplete fracture of one side buckles without disrupting the other side
5-11yo
Groin pain in football
4th most common injury affecting footballers (10%)
3rd longest absence from sport
incorporates abdo, adductors, lumbar spine and SIJ, hip
Sx - pain in lower abdo, groin and testicles; weakness; running/cutting/side-steps, sit ups, coughing/sneezing
