Q

What are some functions of bones?

A
  1. Protect and support the body and organs
  2. Provides skeletal framework of the body
  3. Storehouse for internal CA++ 99% makeup of bones and PO4 85-90%
  4. Production of blood cells which takes place in the bone marrow

Q

What are the different types of joints?

A

Ball and socket: Shoulder and hip which permits movement in any direction
Hinge: elbow movement along one plane and allows flexion and extension
Condylar: functions like a hinge joint but can rotate slightly

Q

What is an avulsion fracture?

A
  1. The bone is torn away by a ligament or tendon
18
Q

What is a segmental fracture?

A
  1. There is a separate piece of bone with a fracture on each end
19
Q

What is a torus fracture?

A
  1. Buckle fracture of one cortex
    *need two different views to see
    *There will be bumping out of the bone
20
Q

What is a greenstick fracture?

A
  1. An incomplete fracture mainly in children
21
Q

What is a pathologic fracture?

A
  1. There is a fracture through weakened bone
    *due to osteoporosis,bone cancer, benign cyst in the bone
22
Q

What is an angulated fracture?

A
  1. The fracture fragments are not anatomically aligned
    *The fracture is at an angle
23
Q

What is a distracted fracture?

A
  1. There is a gap between the fragment fractures
    *Common in avulsion fractures
    *need surgery
24
Q

What is a translated fracture?

A
  1. The fractures changed to a different position
    *shifted out of alignment
25
Q

What is the grading system of an open fracture?

A

Type I: <1cm (puncture wound)
Type II: 1-3cm
Type III: >3cm

26
Q

What is a sub capital neck fracture and a trans cervical neck fracture?

A

Subcapital: right below the head of the femur
Transcervical: middle of the neck of the femur

27
Q

What is a intertrochanteric fracture and a sub trochanteric fracture?

A

Inter: through the intertrochanter
Sub trochanteric: below the intertrochanter

28
Q

What is a type I and type II of a salter-Harris fracture?

A

Type I: fracture through physis (growth plate)
Type II: fracture partway through physis extending up into metaphysis

29
Q

What is a type III and type IV of the Salter-Harris fracture?

A

Type III: fracture partway through physis extending down into epiphysis
Type IV: fracture through metaphysis, physis, and epiphysis; can lead to angulation deformities

30
Q

What is a Type V Salter-Harris fracture?

A

Type V: crush injury to physis
*Look like the growth plate is staring to close

31
Q

What is the purpose of traction?

A
  1. Reduce fracture
  2. Immobilize
  3. Decrease pain and muscle spasm
  4. Correct deformities
  5. Stretch tight muscles
32
Q

What is neurovascular compromise?

A
  1. Damage to nerves from fragments of bone, pressure for casts, splints,and traction
33
Q

What are the 6 P’s of neurovascular compromise?

A
  1. Pain
  2. Pulselessness
  3. Paresthesia
  4. Pallor
  5. Paralysis
  6. Poikilothermia
34
Q

What is poikilothermia?

A
  1. The extremity loses the ability to regulate heat and will assume the temperature of that specific area around it
35
Q

What is fat embolism syndrome?

A
  1. Release of particles of fat into the blood stream from the yellow marrow at site of injury
36
Q

What are the risks factors of fat embolism syndrome?

A
  1. Long bones
  2. Multiple fractures
  3. High serum glucose or cholesterol level
37
Q

What is Avascular necrosis?

A
  1. Loss of blood supply to the bones
    *risk factors mainly hip or anywhere there is bone displacement
38
Q

What is the treatment of Avascular necrosis?

A
  1. Surgical joint replacement
39
Q

What are the stages of bone healing?

A
  1. Hematoma
  2. granulation
  3. Callus formation
  4. Osteoblasts proliferation
  5. Bone remodeling
  6. Complete healing
    *takes around 2 years
40
Q

What is delayed union?

A
  1. The bone will heal but it takes >6 months to a year to heal
41
Q

What is nonunion?

A
  1. < 1/2 of bone fragments joined together
42
Q

What is malunion?

A
  1. Bone healed in state of deformity
