1
Q
Direct Injury
A
- Injury sustained at the site of EXTERNAL FORCE
- e.g. hit by ball
2
Q
Indirect Injury
A
- Injury sustained by an INTERNAL FORCE
- pulled hamstring
3
Q
Soft Tissue
A
- Everything EXECPT bone and teeth
- Can be direct e.g. bruise at the site of external force
- Can be indirect e.g. sprained ankle
4
Q
Hard Tissue
A
- Injury to bone or teeth
- Breaks, dislocations, fractures
5
Q
Overuse Injury
A
- Cause by repetitive action, long-term or poor technique
- Develops OVERTIME due to scar tissue not healing
6
Q
Strain
A
- Tear that occurs in muscle
- Caused by internal force
- Grade 1: Small tear to the muscle
- Grade 2: 50% or more torn
- Grade 3: Complete tear
7
Q
Sprain
A
- Tear that occurs in ligament
- Caused by external forces, joint being bent in wrong direction
- Grade 1: Small tear to the muscle
- Grade 2: 50% or more torn
- Grade 3: Complete tear
8
Q
Contusion
A
-Capillaries are ruptured, causing internal bleeding
- Caused by internal and external forces
9
Q
Skin Abrasion
A
- Scraping and wearing away of skin
10
Q
Laceration
A
- Deep cut or tear to skin
- Caused by contact with sharp device
11
Q
Blister
A
- Caused by friction or burning which leads to build up of serum in skin
12
Q
Closed Fracture
A
- Bone does not pierce skin
- Most common
13
Q
Open Fracture
A
- Bone pierce skin
- Bone can be seen
- Causes bleeding and open wound
14
Q
Complicated Fracture
A
- Damage to major nerves, organs, blood vessels
- Life threatening
15
Q
More specific fractures
A
- Complicated Fracture: Breaks into 2 parts
- Comminuted Fracture: Breaks into 2+ parts
- Incomplete Fracture: Bone cracks
16
Q
Dislocation
A
- Abnormal separation in a joint between two bones
- Caused by direct or indirect injury
17
Q
Phase 1: Acute Inflammation
A
- Fast and painful
- Vasodilation of blood vessels to increase blood in the area
- RICER
18
Q
Phase 2: Repair Inflammation
A
- WBC clean up the debris from the injury
- New tissue begin to form
- 3-6 weeks
19
Q
Phase 3: Remodelling Inflammation
A
- More scar tissue to be produced
- Balance of exercise and rest
