Shoulder Dislocation
By Kristen, Erica and Taylor 1

2. Shoulder Separation vs. Shoulder Dislocation
Contact between your clavicle and scapula
Shoulder Dislocation
Loss of contact between your humerus and the socket of shoulder blade (scapula)
**Important to distinguish the difference because treatment and
management are different.

3. Glenohumeral Joint
Made up of 3 bones that connect in one place: humerus, scapula, clavicle
Ball and socket joint, ball of the humerus fits into the glenoid cavity
Labrum is the piece of cartilage that lies in between the head of humerus
and glenoid
Rotator Cuff muscles: supraspinatus, subscapularis, infraspinatus, teres minor
Ligaments that help: coracohumeral ligament, 3 glenohumeral ligaments

4. How Shoulder Dislocation Occurs
Generally occurs after sports related injuries or a bad fall
95% of cases humerus is pushed in front of the shoulder blade other 5% humerus is pushed behind shoulder blade
Posterior dislocations frequently occur after seizures
Common in skateboarding, swimming, hockey, shoulder pressing (weightlifting)

5. Diagnosis
Must be examined first and foremost to determine whether there is nerve or blood vessel damage
X-ray used to determine the pattern of shoulder dislocation or fracture

6. Symptoms Pain Arm held at side, forearm turned outward
Loss of normal rounded deltoid muscle
If there is nerve damage there can be feelings of pins and needles, numbness, or discoloration through the arm and hand

8. Classifications
4 types of classifications:
Anterior (most common) 8

9. Posterior 9

10. Inferior(very uncommon)10

11. Subluxation 11

12. Treatment
-Surgery or reduction
-Shock therapy
-Physiotherapy 12

13. Reduction First: X-rays should be taken to rule out any fractures
Reduction: A doctor puts the head of the humerus back into the joint
*** You should not pop your own shoulder back in, it can cause severe damage 13

14. Surgery -preferably done in open surgery under direct vision
-a small scope is inserted in a tiny incision in the joint to view the extent of the injury (arthroscopic)
-open surgery is used to repair the shoulder
-full recovery takes several months 14

15. Tens Machine
-Does not repair the dislocation it just helps speed up the healing process
-Sends electric currents through the muscles, loosening them up 15

16. Rehabilitation Seeing a physiotherapist is recommended
Strengthening and mobility exercises
Taping the shoulder for extra support
** After shoulder dislocation you are more susceptible to re injure

17. Post Rehab Prevention
Continue flexibility and strengthening exercises.
Taping the shoulder for support when playing sports.
When starting off, do not go into full contact sporting situations.
Have a daily routine to continue to strengthen the shoulder. 17

18. Prevention Strategies
Balanced upper-body exercises:make sure that you are making your workouts balanced, working out different muscles around your shoulder.
Take it easy: when starting to workout after coming back from a dislocated shoulder, take it slow, don't rush into heavy weights. Also, watch out for certain range of motions so that you do not aggravate your shoulder further.
Sports-specific exercises: once you are cleared to play, you may want to start and focus on the range of motions that you use in your specific sport. Again, begin easy on your shoulder and then increase the difficulty.
Plyometric exercises: working with medicine balls, and weight training is beneficial for two reasons; one- they are done fast, two-they work on shortening and lengthening your muscles. 18
