Q

Characteristics to describe a fracture

6 listed

A
  • Type
  • Location
  • Side
  • Bone
  • Displacement
  • Angulation
34
Q

Phases of bone Healing: Intermediate

A

Fracture/Hematoma

35
Q

Phases of bone Healing: 48 hours

A
  • Inflammatory cells arrive
36
Q

Phases of bone Healing: 7-14 days

A

Granulation tissue forms between fragments, with vascularization of the hematoma

Radiographs - lucency and softening of fracture

37
Q

Phases of bone Healing: 4-16 weeks

A
  • Progenitor cells differentiate into fibroblasts and chondroblasts
  • produce a matrix of fibrous tissue and cartilage, woven bone is deposited by osteoblasts
  • Radiographs: callus
38
Q

Phases of bone Healing: Months

A

Woven bone is replaced by lamellar bone

39
Q

Phases of bone Healing: months to years

A

Remodeling

40
Q

Bone Healing Complications: Delayed union

A

fracture healing takes 2x as long

41
Q

Bone Healing Complications:Non-union (pseudoarthrosis

A

Fracture does not heal in 6-9 months

42
Q

Bone Healing Complications: Malunion

A

Healing in an abnormal position
