1. Injuries

2. Lesson Goals;
Become familiar with specific injuries to the shoulder, knee, elbow and ankle
Be able to identify different types of injuries
Discuss causality of specific injuries i.e; motion, mechanics and overuse
Explore taping techniques to immobilize and protect an injured limb or joint

3. Shoulder Injuries Tendonitis Impingement Syndrome (very common)
Multi-Axial Joint
↑ ROM  ↑ Risk of Injury
↑ Mobility  ↓ Stability
Overhead movement  ↑ Stress to Shoulder Joint
Many Types of Shoulder Injuries:
Tendonitis
Impingement Syndrome (very common)
Tears, Fractures, Separations & Dislocations

4. Impingement Syndrome Implications; Most common in the AC Joint
Acute or Chronic? Why?
Lack of space and many structures passing through the AC joint
Caused by excessive abduction of the Humerus (why abd?)
Implications;
Bone Spurs
Inflammation of structures and joint capsule
Loss of ROM, function and eventually strength
Preventative measures?

5. Impingement syndrome

6. AC Separations & Sprains
Function:
- allows to raise arm above head
Mechanism of Injury:
- direct force (body check)
- falling on outstretched hands
Severity:
- grade 1,2,3, sprains
- grade 3 = completely torn
- step or piano key deformity
- surgery required
Recovery & Prognosis:
- RICE!!! & Sling (different types)
- Restore full ROM
- Restored Strength
- Return to play at athletes discretion
Sling used to take away downward force acting on the shoulder and to lift it back to its natural position.
Different types of slings allow you to not only lift the arm but also press down on the clavicle bone to bring the joint back to its normal position
(only if athlete can tolerate pressure on clavicle
Allows you to raise your arm above your head

7. Dislocations and Separations
A dislocation occurs when a bone is displaced from its original location. Depending on the severity, tendons and ligament may be sprained or torn.
The joint looks deformed/awkward
Painful when touched
The joint is not useable
Medical attention is required! Do not try to put it back in place yourself!, you may cause more damage!

8. SHOULDER DISLOCATIONS
Account for 50% of all dislocations in the body
- ROM
- relies on supporting muscles for stability
- surgery usually not necessary, unless tissues are torn,
- RICE & Sling
Anterior Dislocation most common (95% of all shoulder dislocations)
- Head of the Humerus is forced out anteriorly & Inferiorly
- direct impact or forced abduction & external rotation
Recovery:
RICE, Restore ROM & strength rotator cuff muscles
Release tension in dominant muscles (pecs, lats, trapezius)
Post Surgery  joint immobilized for up to 6 weeks (sling)
several months for full recovery
more susceptible to for more dislocations in the future…..why?

9. Rotator cuff muscles

10. Elbow Injuries Medial Epicondylitis: (golfer’s elbow)
Inflammation on the medial aspect of the elbow
Involves muscles that originate at the medial aspect of the elbow
Cause: (chronic overuse)
- repeated flexion & or pronation (wrist)
- golf, pitching, javelin, bicycling, weightlifting
Recovery:
- can be lengthy (months/years)
- RICE
- deep tissue manipulation (ART)
- practice proper technique (deadlift example)
- massage wrist flexors
- stretch wrist extensors
- strengthen wrist flexors
- condition wrist extensors

11. Elbow Injuries
Lateral Epicondylitis (tennis elbow) - inflammation of the lateral aspect of the elbow - involves muscles that originate at the lateral aspect of the elbow Cause: (chronic overuse) - repeated extension & or supination of the wrist - novice player, poor technique, poor equipment (heavy racquet) - inadequate strength, power, flexibility & endurance Recovery for both: - can be lengthy (months) - RICE - deep tissue manipulation (ART) - practice proper technique - massage wrist extensors - stretch wrist flexors - strengthen wrist extensors - condition wrist flexors

12. Knee Injuries Most traumatized joint…why?
Many sports place stress on the knee
Complexity of joint increases its chance for injury
Most common injuries:
Patello-Femoral pain syndrome (Chronic)
Improper tracking of the patella due to muscle length & tension issues (pulley system)
Ligament Injuries (ACL & PCL)
- Factors contributing to Knee Injuries:
Position of knee ( joint angles )
Foot fixed to the ground (cleats?)
Angle & Force of Trauma
Previous injury (degree, proper rehabilitation)
Strength of muscles crossing the joint
Improper execution of movement
Muscle imbalances

13. ACL & PCL Injuries Recovery:
ACL  prevents anterior translation of tibia
Injury most commonly occurs from planting & twisting motion
PCL  prevents posterior translation of the tibia
Injury most commonly occurs from hyperextension
falling on the tibia with the knee flexed at 90°
Not as common due to strength of PCL compared to ACL
Recovery:
RICE, Strengthen & improve flexibility of muscles around Knee & Hip
(Post Reconstructive Surgery)
Biking within first 2 months
Light jogging within 4 months
Return to sport within 6-9 months minimum

14. The Knee

15. Jumpers Knee

16. “Jumpers Knee” Treatment?
Inflammation of the inferior aspect of the Patellar Tendon
Similar to Patellar Tendinitis or Patellar-Femoral Syndrome
Caused by excessive jumping (incorrectly)
Pain is right below the knee cap
Treatment?
Correct jumping technique
Similarly to Patellar Tendinitis, correct muscle length and tension discrepancies
RICE!
Tape Jumpers Knee to aid in healing and recovery!

17. Ankle & Foot Injuries High risk for injury
Foot in contact with the ground
Supports entire body
First joint to absorb forces from the ground
Composed of 26 bones
15 Phalanges, 5 Metatarsals, 7 Tarsals, Tibia & Fibula
(most complex joint)

18. Lateral & Medial aspects of the Ankle

19. Ankle & Foot Injuries Inversion Sprains (turning over on your ankle)
Involve 1 or all 3 of the lateral ankle ligaments
Anterior & Posterior Talofibular Ligaments
Calcaneo Fibular Ligament
Most Common ankle injury……why?
Lateral supporting ligaments  WEAK
Medial supporting ligament(s)  STRONG
it is more difficult to Evert the foot because the Talus butts up against the distal head of the Fibula
Eversion sprains are often mistaken for distal Fibular head fractures
Mechanism of Injury:
Explosive side-by-side motion, such as in tennis or basketball
Ankle sprain can occur during any weight-bearing activity (walking)
Inversion sprains are very common for individuals who wear high heeled shoes

20. Ankle & Foot Other Potential Mechanisms of Injury? Landing from a jump
Stepping or landing on opponent’s foot
Changing directions
Decelerating
Uneven surfaces
Improper footwear for sport in question
Diagnosis:
Pain, swelling, tenderness, unable to walk, bear weight, visual deformity
Recovery:
RICE, ROM & Strength of supporting structures
“PROPRIOCEPTION!!” (Neural & Muscular Balance) VERY IMPORTANT!
Moderate ankle sprain (grade 1 & 2)  1 to 6 weeks of rehabilitation
Severe Ankle sprain (grade 3)  8 to 12 months of rehabilitation

21. Where do many injuries originate from and why do they occur in the first place?
Although the injury & symptom may be in one of the joints studied in this unit, the fact is that a good majority of all injuries stem from an improper position of the hip.
More particularly, the muscles that attach to the hip are struggling to keep the hip in a neutral position during bracing and movement.
Your exercise and control and stability program should begin with reestablishing proper muscle balance within the hip joint.
The second most common reason for most injuries is improper execution of movement.
The third most common reason is poor nutrition, mental/emotional stress and poor sleeping patterns or not enough sleep (recovery)

Medial epicondylitis or inflammation of the tendon junction on the medial aspect of the humerus
Patellar-Femoral Syndrome
Inversion Sprains

24. Test your knowledge part 3
1)To treat this injury, rehabilitation of the rotator cuff muscles is crucial
2) This injury requires massaging the extensors of the forearm as a first step to recovery
3) This ankle injury is less common due to the strength and size of the deltoid ligament
4) This knee injury is often followed by severe swelling and little to no pain after the immediate trauma
5) Most injuries originate from structural imbalance of this joint
dislocations, AC separations, not impingement which requires relaxation of the major muscles of the shoulder girdle
Lateral epicondylitis or tennis elbow
Eversion sprains
ACL or PLC complete tears
The Hip joint
