– Discussion: – anatomic variations: of tendons in 1st extensor compartment; – APL & EPB tendons may occupy separate canals, or lie together in one osseofibrous canal; – commonly there is one EPB and multiple APL; – there is separation of first extensor compartment more often in pts w/ DeQuervain’s tenosynovitis than in those w/o … Read more
– Discussion: – has become standard technique for stabilizing types II & type III frx; – either two lateral pins, or one lateral and one medial pin may be used and both should penetrate the cortex; – medial and lateral pin insertion provides better stabilization; … Read more
– 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; … 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: 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 … Read more
