Transcript of The Joints

Types of Synovial Joints
There are SIX different types of synovial joints characterized by the movement the joint permits:

GLIDING (Arthrodial)
: Conncets flat or slightly curved surfaces = Tarsals / Carpals

HINGE (Ginglymus)
: A convex portion of one bone fits into a concave portion of another bone allowing movement in ONE plane = Phalanges / Radius-Ulna

PIVOT (Trochoid)
: Rotation in ONE plane where a rounded point of one bone fits into a groove of another = Atlas / Axis

: Movement happens in TWO planes = Wrist / Metacarpal-digit

: Allow movement in TWO planes but no rotation = Thumb

BALL-SOCKET (Spheroidal)
: Allows for THREE planes of movement = Hip / Shoulder
Your Body has
206** BONES
360** JOINTS

Shoulder Separations
Rotator Cuff Tears
Biceps Tendonitis
Shoulder Dislocations
Shoulder Injuries & Pain
A) Acromioclavicular Ligament
I) Coracoclavicular Ligament
H) Coracoid Process
G) Glenohumeral capsule
F) Lesser Tubercle of Humerus
E) Biceps Tendon (Long Head)
D) Coracohumeral Ligament
C) Coracoacromial Ligament
B) Acromion Process
J) Clavicle
K) Humeral Head
Tear to Lateral Collateral
Talofibular Ligament
Tear to Lateral Collateral
Calcaneofibular Ligament
Tear to Lateral Collateral
Tibiocalcaneal Ligament
Tibionavicular Ligament
Tear to Ant Tibiofibular Ligament
Ligament Tears
Patellofemoral Syndrome
Knee Injuries & Pain
____ Stabalizes the lateral side
____ Cushions shock of impact
____ Stops femur from sliding off tibia
____ Stabalizes the medial side
____ Stops tibia from sliding forward
____ Fulcrum for knee extension
____ Shockabsorbing & stabalizing
Lat Collateral Lig
Post Cruciate Lig
Med Collateral Lig
Ant Cruciate Lig
Articular Cartilage
Pivot or Trochoid
Ball-Socket or Spheroidal
Hinge or Ginglymus
Conyloid or Ellipsoid
Gliding or Arthrodial
Attach one or more bones together
Tough bands of white fibrous tissue
Small amount of stretch
Static stabilizers of joints
Can increase in strength with training
Will tear beyond their threshold
Attach muscle to bone
Composed of white fibres of collagen
Will stretch moderately
Will tear beyond their threshold
S - Swelling, instant or over time
H - Heat or increase in temperature of area
A - Altered, impaired function
R - Red (or purple) and bruising
P - Painful to touch or move
P - Pressure
I - Ice
E - Elevation
R - Rest
Rest - R
Ice - I
Compression - C
Elevation - E
Elevation, Ice and Pressure (Compression) should be used at the same time to reduce swelling ...
(1) Makes diagnosis of extent easier
(2) Alleviates pain of swollen tissues
SPRAINS: Damage to tendons and ligaments
PULLS / STRAINS: Damage to muscles
3 Levels of Severity:
1st degree - Mild, fast healing if treated properly
2nd degree - Moderate, medical help required
3rd degree - Severe, may require surgery

TENDONITIS: Inflammation of tendon
Rest/Ice/Compression --> Corticosteroids
Damage to Tissues:
DISLOCATIONS: One bone is displaced from its original location - Usually with damage to capsule and ligaments but could also involve tendons and muscles

SEPARATIONS: Joint ligaments (eg: AC joint) damaged - Same levels of severity as strains / sprains

CARTILAGE DAMAGE: By far the most often damaged area is in the knee due to lateral movements
Hyaline (joints, ribs, nose, lungs)
Fibrocartilage (vertebral discs)
Elastic (ear, epiglottis)

SHIN SPLINTS: Tearing of the interosseous membrane or periosteum of the tibia due to overuse without adequate recovery time
Other Injuries
Supporting Tissues
Amount of supplied blood needed
Ligaments / Cartilage avascular
Bones / Muscles vascular
Vascular tissues heal faster
