1. Mechanisms
Soft Tissue Trauma

3. Critical Thinking
A baseball player slides into home base, severely scraping the skin on the left side of his thigh. What is the force and type of injury produced?
A shortstop is hit in the shin by a batted ball that took a bad hop. What is the force and type of injury sustained by this athlete?

4. Purpose Provide foundation for: Identification Understanding
Management of sports injuries.

5. 3 Primary Tissue Stresses
Tension: force that pulls or stretches tissue
Compression: crushes tissue
Shearing: moves across the parallel organization of the tissue.

6. Contractile vs Non Contractile
Part of the muscle:
Muscle
Tendon
Bony insertion
Non Contractile
Skin
Joint capsules
ligaments,
Fascia
Cartilage
Dura mater
Nerve roots

7. Your skin First defense to infection and or disease water proof
trauma is visually exposed and is called a wound
non-contractile

8. Friction Blister:
Moi: continuous rubbing.
S/S: fluid, bubble

9. Skin Bruise
MOI: blow, crushing
S/S: bleeding

10. Abrasion
MOI: scraping against rough surface.
S/S: skin is torn away or reddened

11. Laceration
MOI: tearing
S/S: irregularly torn

12. Skin Avulsion
MOI: tearing
S/S: tissue is completely ripped from source

13. Incision MOI: cutting S/S: skin has been sharply cut

14. Puncture Wound
MOI: compression
S/S: penetration of skin by sharp object
