Characteristics to describe a fracture

6 listed

A

Type
Location
Side
Bone
Displacement
Angulation

Q

Phases of bone Healing: Intermediate

A

Fracture/Hematoma

Q

Phases of bone Healing: 48 hours

A

Inflammatory cells arrive

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

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

Q

Phases of bone Healing: Months

A

Woven bone is replaced by lamellar bone

Q

Phases of bone Healing: months to years

A

Remodeling

Q

Bone Healing Complications: Delayed union

A

fracture healing takes 2x as long

Q

Bone Healing Complications:Non-union (pseudoarthrosis

A

Fracture does not heal in 6-9 months

Q

Bone Healing Complications: Malunion

A

Healing in an abnormal position

Q
