ANTR 350 1st Edition Lecture 15Outline of Last Lecture I. Upper limb appendicular skeletonII. Pectoral girdleIII. HumerusIV. RadiusV. Ulna Outline of Current Lecture II. Upper limb jointsIII. Clinical correlatesCurrent Lecture-major joints of the upper limb-glenohumeral-ball and socket; triaxial-highly mobile, unstable-clinical correlates-shoulder separation: dislocation of acromiclavicular joint-causes: hard fall, direct impact-shoulder dislocation: dislocation of glenohumeral joint-causes: humerus is driven forcibly inferiorly and anteriorly, injured during abduction, injured during fall onto outstretched hand-impingement syndrome: head of humerus compresses tendon and bursa; inflammation of the arch and rotator cuff or rupture-causes: bursitis, tendonitis; repetitive use of cuff muscle and overhead activities-rotator cuff tear: repetitive stress (motions above horizontal)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-tear of the tendon of the supraspinatus muscle-frozen shoulder: adhesive capsulitis: thickening of joint capsule-stiffness pain, extreme loss of range of motion-more likely after procedures and conditions that immobilize the arm-elbow joint-hinge; uniaxial-articulations-head of radius articulates with capitulum of humerus (“pulled elbow” is dislocation of radius head at radiohumeral joint)-ulnohumeral joint: trochlear notch of ulna articulates with the trochlea of the
