Tissue Injuries What is a tissue Group Types

Tissue Injuries

What is a tissue? � Group � Types: of similar cell types

Tissue Injuries Classification � Why might it be difficult to classify an athlete’s injury?

Tissue Injuries � Forces › Compression › Shear – parallel to plane › Tension › Torsion � Pads?

Practice � Demonstrate each of the forces using a sports “motion. ” (must be different than the examples given in class – be creative) � The class will guess what force is being demonstrated.

Acute vs. Chronic Injury

Bony Tissue � Anatomy of a long bone (draw and label) › Diaphysis › Epiphysis › Compact bone �Young = cartilage = flexible › Epiphyseal discs = still growing � Forces naturally received?

Growth Plates

Demo/share 4 forces on the bones

Common Bone Injuries � Fractures › Simple/Closed › Compound/Open › › › Depressed Transverse Comminuted Oblique Epiphyseal › › › Spiral Greenstick Avulsion Impacted Stress Fracture

Soft Tissues � Types � Anatomy › Layered or many fibers › High amounts of protein: collagen and elastin

SKIN � Concerns � Common Injuries › Abrasion › Laceration › Puncture › Blister › Bruise

Why is skin most commonly injured and what are some concerns with skin injuries?

Muscles and Tendons Tension � Tendons � Injuries � › Contusion �Grade 1 �Grade 2 �Grade 3 › Strain �Grade 1 �Grade 2 �Grade 3 › Cramp › Tendonitis

� What is the purpose of a tendon? is more susceptible to injury, muscle or tendon? WHY?

Joints � Classification › Fibrous › Cartilaginous › Synovial

Synovial Joints � Components › Synovial Membrane › Articular Cartilage › Articular Capsule › Synovial Fluid › Ligament › Bursa

Synovial Joints � Types › › › and Locations Hinge Ball and socket Pivot Condyloid Saddle Gliding/Plane

Common Joint Injuries � Sprain (grade 1 -3) � Bursitis � Dislocation
