37
Q

Type 1

A

A complete physeal fracture with or without displacement

38
Q

Type 1 treatment

A

Rarely will have to be put back in place

Normally just need a cast- all things still intact- unless damage to blood supply, should grow normally once healed

39
Q

Type 2

A

A physeal fracture that extends through the metaphysis, producing a chip fracture of the metaphysis, which may be very small

40
Q

Type 2 treatment

A

Most common

Typically have to be put back in place surgically and immobilised to allow growth to continue

41
Q

Type 3

A

A physeal fracture that extends through the epiphysis

42
Q

Type 3 treatment

A

Occurs rarely
Usually lower end of tibia
Surgery sometimes necessary

43
Q

Type 4

A

A physeal fracture plus epiphyseal and metaphyseal fractures

44
Q

Type 4 treatment

A

Surgery needed to restore bone back and perfectly align growth plate
If not perfect alignment achieved when placed back or during growth, prognosis for growth is poor

45
Q

Type 5

A compression fracture of the growth plate

46
Q

Type 5 treatment

A

Uncommon
Occurs when bone is crushed
Prognosis poor

Reduced
Casted 6 weeks
Usually occur in metaphysis

48
Q

3 week cast
49

50
Q

Hip/groin pain mechanism of injury

A

Torque/twisting with opposing forces
Conjoint tendon pulls up and rotates trunk
Adductor pulls down and rotates upper leg
Opposing forces disruption of muscles at their insertion
Imbalance between weak abdominal muscles in relation to strong leg muscles

51
Q

54
Q

Slipped Upper Femoral Epiphysis (SUFE)

A

Femoral head slips posteriorly

Due to weakness of growth plate- sheer force across GP

55
Q

SUFE Epidemiology

A

During periods of accelerated growth
Antalgic gait/limb
Leg short and externally rotated
Surgery

56
Q

Avascular necrosis of hip

A

Ball/socket joint
Articular cartilage
Damage –> collapse/flattening of femoral head
blood supply is through neck of femur, so is shut off

57
Q

Avascular necrosis of hip causes

A

NOF
Dislocation
ETOH
systemic cortisone

A

Conservative

Surgical-decompressing femoral head

60
Q

Blood supply age 8-10 head of femur
