(See also: inferior gluteal artery) Discussion major blood supply to gluteus medius and minimus; superior gluteal artery and nerve leave the pelvis above piriformis; emerges above piriformis, after passing thru greater sciatic foramen; once pass the notch, it divides into: superficial branch supplying maximus; deep branch enters deep surface of medius in intermuscular plane … Read more
– See: proximal femoral shaft fractures / – Discussion: – definition: – between lesser trochanter and 5 cm distal, even as far as center of isthmus of the femoral shaft; – technically starts below the lesser tuberosity; – medial and posteromedial cortex is a site of high compressive forces, while lateral cortex experiences high tensile stresses (forces … Read more
– See: Bone Healing w/ Plates – Discussion: – useful in subtrochanteric frxs since it permits insertion of at least two cortical screws into proximal fragment (calcar); – having multiple points of fixation above and below the fracture prevents varus or rotational migration; … Read more
– Precautions: – because succinylcholine causes an increase in intra gastric pressure that may lead to gastric aspiration, crycothyroid pressure should be applied; – also causes increase in intraocular pressure and in relatively contra- indicated with injuries in an open globe; – increases intracranial pressure; – Precautions w/ Spinal Cord Injury: – w/ possible cervical … Read more

– 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
– 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
