Overhead Athlete Flashcards
what is the origin and insertion of the pec minor?
origin : ribs 3-5
insertion: coracoid process
what structure of the anterior chest / shoulder overlies the brachial plexus and the subclavian artery and vein?
pec minor
what is the origin and insertion of the lat dorsi?
origin - thoracolumbar fascia
insertion - biceps groove
what is the innervation of the lat dorsi?
thoracodorsal nerve
what is the innervation of the teres major?
lower subscapular nerve
which nerve and artery travel through the quadralateral space?
axillary nerve and posterior circumflex humeral artery
what nerve innervates the levator trap and rhomboids?
dorsal scapular nerve
which nerve innervates the SCM and trapezius?
spinal accessory nerve
repeated throwing causes what general change in ROM of the shoulder?
increases ER and decreases IR
an XR shoulder in a youth throwing athlete shows widened physeal plate of the humerus. what is the diagnosis?
proximal humeral eiphysiolysis
what is the typical time of rest needed for the initial treatment of proximal humeral epiphysiolysis?
8-12 weeks
what is the possible complication of untreated little leaguer’s shoulder?
arrest of growth at the growth plate
what is internal impingement?
pathologic micromotion of the humeral head leads to impingement of the deep surface of the supraspinatus, infraspinatus and posterior superior labrum
what is the name of the injury characterized by extraarticular ossification of the posterior inferior capsule of the shoulder?
Bennet lesion
which portion of the shoulder labrum has the poorest blood supply?
anterior superior
lateral winging of the scapula is due to what nerve pathology?
spinal accessory nerve (trapezius weakness)
a throwing athlete has clicking, anterior shoulder pain, loss of internal rotation with positive speeds , O briens and biceps load test. what phase of the pitching is most likely contributing to his condition?
late cocking and deceleration (most harmful to labrum and biceps tendon due to eccentric forces)
