Time for bone healing?

6-8 weeks

Stage 1 for bone fracture healing How long does it take?

Acute Inflammatory Phase Injury -- 4 days

Stage 2 for bone fracture healing How long does it take?

Repair 4 days -- 3 months

Stage 3 for bone fracture healing How long does it take?

Remodeling/Maturation 3 months -- Several years

Avulsion Fracture

Bone is pulled away by tendon or ligament

Stress Fractures

- Athlete complains of a persistent sore spot over the bone. - Often night pain

Spiral Fracture

Torsional force along the length of a bone

Longitudinal Fracture

Fracture runs length of a bone

Compression Fracture

Opposing forces applied to a bone from both ends at the same time. (Occurs at the spine)

Oblique Fracture

Diagonal line across a bone from one side to another.

Comminuted Fracture

Bone is crushed into smaller pieces

Greenstick fracture

Bone bends and fractures only part way through

Transverse Fracture

Fracture travels across and perpendicular to a bone.

Epiphyseal Fracture

Fracture at the epiphyseal plate

Depressed Fracture

Direct impact to the skull

Blowout Fracture

Eye is pushed hard backward and down into the eye socket. Small bones under the eyes get crushed.

Dislocation

2 bones creating a joint no longer articulate

Subluxation

Bones slide out of joint part away & come back in on their own

What are the tissue healing phases?

1. Inflammatory Response 2. Fibroblastic Repair 3. Maturation-Remodeling

What happens in inflammatory response? What is the goal?

- Cells start to die - Vasoliditation - New capillaries form - Type III collagen formation Prepare the body for healing

Important chemicals in inflammatory response?

Phagocytes/Marchophages Leukocytes Histamine Platelets

Time for the inflmmatory phase?

Injury - 4 days

What happens in fibroblastic repair? What is the goal?

Debris removal via phagocytes Scar formation Decrease in capillaries Absorption of type III collagen Develop new tissues Repair the injured site

Important chemicals in fibroblastic repair?

Fibroblasts Chondroblasts Osteoblasts

Time for the fibroblastic repair?

4 days -- 3 weeks

Goal of maturation phase?

Return to normal tissue, strength and function

What happens in maturation phase?

Re-absorption of new chemicals Scar maturation Production of Type 1 collagen

Time for maturation phase?

3 weeks -- 2 years
