Data Trace Editor – See: – Ulnar Nerve: – Anatomy & Sites of Compression of Cubital Tunnel: – Surgical Considerations: – transposition can entail subQ or submuscular transposition with excision of medial intermuscular septum, and release of arcade of Struthers; – in the presence of H.O. the nerve should be … Read more
– Discussion – Examination of Patellofemoral Joint – exam considerations: – generalized hyperlaxity – femoral anteversion – vastus medialis obliquus atrophy – genu valgum – external tibial torsion – patellar dysplasia – trochlear dysplasia – patella alta – pes planus – Radiographic Features: (see: radiographic evaluation of the knee) – lateral view – look for … Read more
– Discussion: – subscapular artery is usually largest branch of Axillary Artery and arises from the 3rd part of the artery; – branches of subscapular artery enter costal surface of Subscapularis muscle, & frequently one or more small twigs arising directly from Axillary Artery do likewise; – from its origin it … Read more
– See: brachial plexus – Discussion: – subscapular and thoracodorsal nerves arise from posterior cord of brachial plexus while this is on costal surface of subscapularis; – both subscapular nerves usually receive fibers from C5 and C6; – upper subscapular nerve passes directly into … Read more
Discussion (see also: subacromial bursectomy) subacromial bursa is large synovial membrane which is adherent to undersurface of coracoacromial ligament, acromion, & delltoid laterally, an is adherent to rotator cuff & greater tuberosity; it envelops proximal humerus, & facilitates gliding of proxiaml humerus under coracoacromial arch References Synovial osteochondromatosis in the subacromial bursa. Subacromial/subdeltoid bursa abscesses. An overlooked diagnosis.
– Surgical Considerations: (arthroscopic rotator cuff repair / acromioplasty) – note that the subacromial bursa is an anterior structure; – it is located from anterior 1/2 to 1/3 of acromion to just medial to A-C joint to 1 to 2 cm anterior to acromion & 2.5 cm laterally; – posterior busrsal wall is thick posteriorly (called posterior bursal … Read more
– See: – arteries of the upper limb – subclavian vein – thoracic outlet syndrome; – Discussion: – injuries are rare because of overlying bony skeleton; – right subclavian artery originates from innominate artery & passes into neck behind the right SC … Read more
– See: subclavian artery and internal jugular approach – Anatomy: – subclavian vein, which in the adult is approximately 3-4 cm long and 1-2 cm in diameter, begins as a continuation of the axillary vein at the lateral border of the first rib, crosses over the first rib, and passes in front of the … Read more
– Discussion: – determine required thickness for the STSG: – since a thick STSG graft harvested from donor site w/ a thin dermal thickness, may lead to a full thickness wound, as well as causing hyperpigmentation of the transplanted STSG; – thick donor sites: posterolateral … Read more
– Examine Recipient Site: – review the reconstructive latter and the requirements for coverage – STSG cannot be placed over bare tendon or bone, and neither can be placed over exposed vessels or nerves; – determine optimal time for grafting; … Read more
