Q

What occurs during a growth spurt?

A
  • bone length changes and then soft tissue length adapts to that
  • leads to changes in coordination and biomechanics
  • effects energy levels

Q

what part of the bone is softer in developing bone? what is the impact of this

A

metaphysis
absorbs greater energy
suscpetable to different forms of fracture
generaly, developing bones are less dense/more porous

Q

Why are joints less stable in children and adolescents?

A
  • muscle development not optimal/fully maturated, reducing core stability
  • reduced cross bridges in ligaments leading to increased laxity
  • joint stability relies less on muscle stability than in adults

Q

How are growth plate fractures classified?

A

Salter Harris classification:

  • type 1: epiphysis completely separated from end of bone, vital portion of growth plate remain intact. require cast but will be normal bone growth once healed
  • type 2: most common. epiphysis and growth plate partially separate from metaphysis which is cracked. Typically have to be surgically put in place and immobilised.
  • type 3: rare. Usually distal tibia. fracture runs through epiphysis and separates part of epiphysis and growth plate from metaphysis. surgery may be necessary. good prognosis if blood supply to separated portion is intact, no displacement, and bone regrows
  • type 4: requires surgery to align growth plate. If this isnt achieved then prognosis for future growth is poor
  • type 5: end of bone is crushed and growth plate is comrpessed. prognosis is poor, growth likely to be stunted

damage to growth plate will reduce future growth at that portion leading to biomechanical imbalances

Q

Buckle fracture

A
  • incoplete fracture when bone buckles without distrupting one side of the bone
  • common due to soft skeleton
  • persistent pain more than a few hours, usually from falling onto wrist
  • 5-11yr
  • Quicker healing time
  • 3 week cast

23
Perthe's disease aka
avascular necrosis of the hip Blood supply of femur heads through the neck of the femur and supplies the head. Anything disrupting this can cause articular cartilage necoriss, changing the shape of the femoral head. Flattening of the head occurs causing hip pain most common in boys from 5-12yrs causing limp
24
causes of slipped upper femoral epiphysis
sheer forces through the epiphysis between femoral head and neck results in a change in the anatomy femoral head slips off femoral neck and this is a weak sight in children/adolescents that isn't present in mature skeleton
25
causes of avascular necrosis of the hip
trauma: - NOF fracture - dislocation - ETOH systemic cortisone
26
what happens to the femoral head in avascular necrosis
flattening of the femoral head
27
management of avascular necrosis
generally conservative | may need surgical intervention
28
Perthe's disease presentation
- painful hip - limp - 5-12yr - boys more commonly
29
causes of slipped upper femoral epiphysis
- femoral head slips posteriorly - due to weakness of growth plate during periods of accelerated growth
30
gait in slipped upper femoral epiphysis
antalgic
31
Ddx back pain in young athletes
Less common than in adults. - spondylolysis (Pars defect)- relatively common - spondylolisthesis - scoliosis - scheuermann's disease - osteomyelitis - congenital abnormalities - ankylosing spondylitis - juvenile RA - Malignancy
32
Spondylolysis aka
Pars defect = defect on pars interarticularis
33
epidemiology spondylolysis
6% gen pop 50% sporting back pain due to repetitive hypertextension more common in males
34
which vertebrae are commonly affected by sponylolysis/pars interarticularis
L4/5 or L5/S1
35
sports causing spondylolysis
those causing repetitive spinal extension: - football - crickets - gymnastics - weightlifting
36
common presentation spondylolysis
- sport related pain - worst on activity also ask: - multiple joint pain/swelling - night pain - morning stiffness - neuro/systemic Sx
37
common presentation spondylolysis
- sport related pain - worst on activity - pain on lumbar extension specifically single leg extension or extension combined with rotation
38
other Q to ask someone with suspected spondylolysis
- multiple joint pain/swelling - night pain - morning stiffness - neuro/systemic Sx
39
Ix for spondylolysis
- Xray- AP, lat, oblique - SPECT/CT- determine the reactivity of lesion and whether it is acute or chronic - MRI first point of call although difficult to tell if chronic or acute
40
Treatment for spondylolysis
- relative rest from aggravating activties - analgesia rehab: - core - flexion avoid extensino hamstring stretches to reduce tension - aerobic fitness - sports specific - bracing in an extreme example
41
traction apophysitis
areas in the developing skeleton where the tendon attaches onto the bone and can become painful and inflamed More common in children because the area is not yet hardened associated with a lot of growth in short time
42
Extreme consequence of traction apophysitis
avulsion fracture | The area of bone that it attaches to it softer than adult skeleton
43
common examples of sites of traction apophysitis
- osgood schlatters (tibial tuberacle) patella tendon - Severs (calcaneum) achilles tendon - Sinding Larsen Johansson (inf. pole patella), pat tendon - Little league elbow (med. epicondyle) wrist flexor - Iselins (5th metatarsal) peroneus brevis
44
most common traction apophysitis
Osgood schlatters | inflammation at the site of patella tendon attachment at the tibial tubercle
45
Osgood schlatters-clinical findings
- TOP tibial tubercle - protruded tibial tubercle - Pain on resisted knee extension/squatting - pain on passive knee flexion - restricted hamstring flexibility
46
Biomechanical risk factors for osgood schlatters
- Poor quad/hamstring flexibility - growth spurt - increased Q angle - patella alta (sits high in trochlear groove) overpronated feet - knee valgum increases traction occurring at tibial tuberosity
47
Severs Disease- clinical findings
Traction apothysitis where achilles attaches to calcaneus - TOP calcaneal growth plate - Pain and restriction on DF stretch - Pain on resisted PF/calf raise
48
Biomechanical factors predisposing to severs disease
- overpornation/valgus at the ankle | - stiff forefoot
49
Mx traction apophysitis
- relative rest (change in activity) - treatment of inflammation - address biomechanical factors - improve movement patterns
50
why is there increased risk of dislocation in children and adolescents
cross bridges of ligaments not fully formed and stability provided by muscle development is not optimised
51
Patello-femoral stability mechanism
- patellar alignment is maintained by fibrous structures | - these provide medial and lateral pull (vastus medialis and IT and vastus lateralis providing tension)
52
subluxation vs dislocation
subluxation is partial loss of joint congruity | dislocation is complete loss
53
What must fail in order for dislocation to occur?
One of the medial structures will fail either by: - medial patella femoral ligament detaching at femoral attachment - avulsion fracture at chondro-osseous junction This allows lateral structures to pull kneecap out of the trochlear groove
54
Biomechanical risk factors for patella instability/dislocation
- shallow femoral trochlear - hypoplastic lateral femoral condyl - patella shape - patella alta - poor VMO strength
55
injury prevention concepts
- anthropometric measurements - load management - generic warm up - functional movement screening - injury prevention exercise programmes
56
Aims of the warmup
- graduated physiological preparation for exercise - turn on neurological pathways for muscle activation 'proprioception' - physical and mental rehearsal of sports-specific movements
57
FIIT principle
frequency intensity time and type part of load management
58
current concepts of injury prevention
- hamstring/gluteal/adductor/gastrocnemius strengthening postural/core stability training proprioceptive training myofascial release
