– Anatomy: – suprascapular nerve is derived from upper trunk of brachial plexus, typically receiving fibers from C5 and C6; – it contains both motor and sensory components, and sends sensory branches to both the glenohumeral and AC joints, but does not innervate the skin; – it passes downward, laterally (deep to the omohyoid and … Read more
– See: – Abductors of the Shoulder: – Rotator cuff; – Anatomy: – origin: medial 2/3 of supraspinatus fossa above spine of scapula; – insertion: superior surface of greater tuberosity of humerus and capsule of shoulder joint; – demensions: supraspinatus averages 25 mm wide and has … Read more
– See: Sural nerve: – Anatomy: – arises from popliteal artery or from sural artery; – it runs adjacent to Sural Nerve, & regularly giving off small branches to it; – it gives off a branch to skin that supplies upper part of the calf, which corresponds to the … Read more
– See: Innervation of Lower Limb Muscles – Anatomy: – from the lumbo-sacral plexus, arises from posterior branches L4, L5, S1; – exits the pelvis and enters the gluteal regioin through the upper margin of the greater sciatic notch, just superior to the piriformis muscle. – it … Read more
– See: – Lateral Compartment – Anterior Compart – Deep Posterior Compartment – Discussion: – superficial posterior compartment contians gastrocnemius, soleus, popliteus, & plantaris muscles. – sural nerve, short & long saphenous veins are also w/in this compartment, but there are no … Read more
– See: Deep Palmar Arch – Discussion: – superficial arch is much larger & important than the deep arch – classical complete arch present in only 34% (from radial & ulnar) – variations: – entirely from the ulnar artery in … Read more
(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: Rotator cuff: – Anatomy: – origin: entire anterior surface of the subscapularis fossa; – insertion: lesser tuberosity of humerus and capsule of shoulder joint; – The Subscapularis Footprint: An Anatomic Description of Its Insertion Site. – action: – main … 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
