  15. 24. Rotator Cuff <ul><li>The rotator cuff connects the humerus to the scapula. </li></ul><ul><li>The rotator cuff is formed by the tendons of four muscles: </li></ul><ul><ul><li>the supraspinatus, </li></ul></ul><ul><ul><li>infraspinatus, </li></ul></ul><ul><ul><li>teres minor, and </li></ul></ul><ul><ul><li>subscapularis. </li></ul></ul>
  16. 26. <ul><li>Bursitis </li></ul>
  17. 27. Bursitis <ul><li>Bursitis is defined as inflammation of a bursa. </li></ul><ul><li>Bursae are closed, round, flattened sacs that are lined by synovium and separate bare areas of bone from overlapping muscles (deep bursae) or skin and tendons (superficial bursae). </li></ul><ul><li>They occur at areas of friction or possible impingement. </li></ul><ul><li>Bursae function to reduce friction and allow a greater range of movement when muscle contracts. </li></ul><ul><li>They may or may not communicate with the adjacent joint space. Symptoms of bursitis include inflammation, localized tenderness, warmth, edema, erythema of the skin (if superficial), and loss of function </li></ul><ul><li>When inflamed, the synovial cells increase in thickness and may show villous hyperplasia. </li></ul><ul><li>Bursal lining eventually may be replaced by granulation tissue prior to fibrous tissue formation. </li></ul><ul><li>The bursa becomes filled with fluid, which is often rich in fibrin. Hemorrhage sometimes occurs. </li></ul><ul><li>Patients often complain of a dull shoulder ache. </li></ul><ul><li>The most common symptom of subacromial bursitis is tenderness over the greater trochanter (and beneath the deltoid muscle) that disappears when the arm is abducted. </li></ul>
  18. 28. Clavicle fracture <ul><li>Most common bone fractured </li></ul><ul><li>The weakest part being the junction of the middle and lateral thirds </li></ul><ul><li>Class A (middle third fractures) (80%): </li></ul><ul><ul><li>Treat with sling immobilization. </li></ul></ul><ul><ul><li>Some prefer using a figure-eight clavicular splint, especially for displaced fractures. </li></ul></ul><ul><li>Class B (distal third fractures) (15%): </li></ul><ul><ul><li>Treat type I (nondisplaced) and type III (articular surface) fractures with sling immobilization. </li></ul></ul><ul><ul><li>Immobilize type II (displaced) fractures in a sling and swathe. </li></ul></ul><ul><ul><li>These may require orthopedic surgical fixation. </li></ul></ul><ul><li>Class C (proximal third) (5%): </li></ul><ul><ul><li>Treat nondisplaced fractures with sling immobilization. </li></ul></ul><ul><ul><li>Displaced injuries may require orthopedic referral for surgical reduction. </li></ul></ul><ul><ul><li>Neonatal fractures generally heal spontaneously in several weeks without special treatment. </li></ul></ul>

  20. 30. Acromio-clavicular (AC) separation (separated shoulder) <ul><li>Mechanism of injury- fall onto point of shoulder </li></ul><ul><li>If there has been significant disruption (or a fracture to the clavicle itself), the area will appear swollen and deformed compared with the other side. </li></ul><ul><li>The patient will avoid movement, do to pain. </li></ul><ul><li>Gently have the patient move their arm across their chest while you palpate in the AC region. </li></ul><ul><ul><li>This will cause pain specifically at the AC joint if there is separation. </li></ul></ul><ul><li>Tenderness is felt at the junction, or the site of the AC (acromioclavicular) joint . </li></ul>
  21. 40. Paralysis of the Serratus Anterior <ul><li>Results from injury to the long thoracic nerve causing a “Winging of the Scapula” </li></ul>

  58. 124.

  65. 137. Herpetic Whitlow <ul><li>Herpes simplex virus may cause an intense, painful skin infection. </li></ul><ul><li>The fingertip is sore and swollen but is not as firm as in a felon. </li></ul><ul><li>The appearance of tiny fluid-filled blebs (vesicles) on the fingers is diagnostic . </li></ul><ul><li>A herpetic whitlow is often mistaken for a felon. </li></ul><ul><li>The disorder eventually goes away on its own. </li></ul><ul><li>Surgery is not needed. </li></ul>
  66. 138.
