By Kristen, Erica and Taylor Shoulder Dislocation By Kristen, Erica and Taylor 1

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.

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

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)

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

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

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

Posterior 9

Inferior(very uncommon) 10

Subluxation 11

Treatment -Surgery or reduction -Shock therapy -Physiotherapy 12

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

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

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

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

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

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
