(see also: Physical Exam; Radiographic Studies for the Shoulder)
– See: – Arteries of the Upper Limb – Anatomy: – branch of axillary artery – smaller than PHCA; – passes laterally around front of surgical neck of the humerus – major blood supply to humeral head is from AHCA; – humeral head is … Read more
– See: Anterior Approach to the Humerus Axillary Approach: Posterior Approach Posterior Approach to Humerus Surgical Approach for Proximal Humeral Fractures Positioning and Draping: supine or beach chair; small soft bolster is placed beneath the shoulder blades to protract the shoulder; head is stabilized to prevent hyperextension and subsequent brachial plexus palsy; place patient in … Read more
– See: Rotator Cuff Tear – Discussion: – see abductors of the shoulder; – common tendon covering top, front, & back of humeral head; – 4 muscles fuse to form this tendon: (subscapularis, supraspinatus,, infraspinatus, teres minor;) – supraspinatus – lies … Read more
Discussion proximal humerus ossifies from four centers: head, shaft, and both tubercles, which unite at age 19 to 20; frx in adult life tend to occur along old epiphyseal lines; depression between tubercles, bicipital groove, contains long head of biceps; tubercles also serve as points of insertion for rotator cuff, w/ subscapularis inserting on lesser … Read more
vascular supply to the humeral head Two Part Articular Segment Displacement fracture plane is through the anatomic (not surgical neck); anatomic neck represents the old eiphyseal plate; surgical neck represents the weakened area below the tuberosities and head approximately 2 cm distal to the anatomic neck; significant chondral defects and minimally separated fragments may go … Read more
Technique decreases interscalene space by tensing anterior and middle scalenes; arm of the affected side placed on the sitting patients thigh with forearm supinated; turn head to the affected side; extend neck and hold breath; positive test is obliteration of the radial pulse; Hyperabduction maneuver tests for compression against axillary pulley which consists of pectoralis … Read more
– Discussion: – refers to a condition in which the shoulder capsule becomes contracted and thickened; – patients note a dramatic decrease in shoulder ROM; – in many cases there is spontaneous resolution after 1-3 years and motion is re-gained; – associated disorders: – cervical spondylosis – hypothyroidism – ref: Prevalence of hypothyroidism in patients … Read more
Discussion may allow use of plain x-rays for dectection of pts with complete Rotator cuff tears; this view showed narrowing of acromiohumeral space to 2 mm or less; view is obtained by having pt actively abduct shoulder to 90 deg and repeating an anteroposterior radiograph
Development of the design of the WRIGHTLOCK Spinal Fixation System began over eight years ago in conjunction with Dr. Ben Allen, Jr., Chief of Staff at the Shriners Hospital for Crippled Children in Greenville, SC. Its design was based on the need for a spinal system that was both low profile and high strength for … Read more
Discussion (see also: rotator cuff) abduction of shoulder is a smooth, integrated motion which has been termed scapulohumeral rhythm by Codman; disruption of this smooth motion is important since asymmetrical movement usually indicates a chronic pathological disorder of the shoulder; there is a 2:1 ratio of movement in GHJ & scapulothoracic joints; clavicle also plays … Read more
