tendinopathy vs tendonitis
tendinopathy= degeneration tendonitis= inflammation
99
progression of tendinotpathy

secondary to other injuries (from rotator cuff tendinopathy or impingement syndrome) primary if baseball, volleyball, etc (5% of time)
151
pathophysiological changes in long head biceps tendinitis
there is LHB sheath thickening, fibrosis, and vascular compromise. * The LHB tendon undergoes degenerative changes, and associated scarring, fibrosis, and adhesions eventually compromise LHB tendon mobility. In effect, the tendon becomes pathologically “anchored” in the groove, end-stage conditions, the LHB tendon can eventually rupture

excessive eccentric force as the arm is brought into extension from flexion. (while proximal biceps rupture is usually correlated with rotator cuff disease) Risk factors include age, smoking, obesity, use of corticosteroids, and overus
157
distal biceps tendon rupture evaluation
-history of single traumatic event -painful pop -palpable and visible retraction of biceps muscle belly (reverse Popeye deformity) -weakness
158
acromioclavicular joint injury causes? what part of the acromion is hurt? what position is arm in?
sports, falling, car accidents The most common mechanism of injury is direct trauma to the lateral aspect of the shoulder or acromion process with the arm in adduction. Falling on an outstretched hand or elbow may also lead to AC joint separation
159

lateral ; adduction
160
the ___ sign is when the clavicle is elevated and rebounds after inferior compression;; seen in acromioclavicular joint injury
piano key sign
161
imaging fro AC joint injury
x ray
162
6 types of AC joint injuries (get progressively worse)
* Type I is referred to as a sprain of the acromioclavicular ligaments only and demonstrates no displacement. * Type II involves tearing of the acromioclavicular ligament and sprain of the coracoclavicular ligament with less than 25% increase in the coracoclavicular interspace or with the clavicle elevated but not superior to the border of the acromion. * Type I and II sprains are managed non-operatively with a sling, analgesia, ice, and physical therapy. * Type III AC joint separation involves tearing of both the acromioclavicular ligament and coracoclavicular ligaments resulting in clavicle elevation above the border of the acromion with a 25 to 100% increased coracoclavicular distance on x-ray compared to the contralateral side. * Type III injuries are frequently managed non-operatively similar to type I and II; however, if the displacement is greater than 75%; the patient is a laborer, elite athlete, or concerned about cosmesis; or is not improving with conservative management, then surgical intervention may be considered. * Posterior displacement of the distal clavicle into the trapezius defines type IV injuries. Type V injuries have a superior displacement by more than 100% compared to the contralateral side. * Type VI is rare and is an inferolateral displacement in a subacromial or subcoracoid displacement behind the coracobrachialis or biceps tendon. * Type IV through VI injuries are typically managed surgically, and warrants referral to an orthopedic surgeon.
