– Discussion: – first major branch of the brachial artery is the profunda brachii; – arises from the brachial artery high in the arm, about level w/ lower edge of the latissimus dorsi tendon (18-25 cm above the medial epicondyle); – leaves brachial artery to pass posteriorly company w/ … Read more

– See: Lateral Approach – Discussion: – allows exposure of the entire distal humerus as well as radial head, radial neck, and biceps tuberosity; – indications for this approach include frxs of distal humerus, old posterior elbow dislocations, radial head frx, radial head excisions, arthroplasties, fixation of distal biceps tendon rupture, and … Read more
– Anatomy: – this nerve is deep motor branch of radial nerve & supplies all of extrinsic wrist extensors except for the ECRL; – radial nerve enters the anterior compartment of the arm lying deeply between brachialis medially & BR & ECRL laterally; – PIN passes thru supinator muscle in its course from anterior to … Read more
– Discussion: – branch of the Axillary Artery – largery than AHCA. – passes around the posterior astpect of the surgical neck of the humerus with the Axillary nerve (thru quadrangular space ); – runs w/ the nerve around the humerus under the Deltoid muscle Anatomy of … Read more
– See: – Anterior Approach Shoulder – Post Approach to Humerus – Discussion: – indicated from frx of the scapula, esp when the pathology is posterior; – Technique: – positon the patient in the prone or lateral position; – skin incision is made … Read more
– See: Posterior Approach to the Humerus; – Discussion: – considered to be the most versatile approach to the elbow; – most surgeons use straight longitudinal incision, which avoids olecranon tip, by shifting the incision slightly laterally or medially; – Variations of Posterior Approach: – Transolecranon Osteotomy … Read more
– See: – Anterior Approach to Humerus – Posterior Approach to the Elbow; – Plate Fixation of the Humerus; – Indications: – Distal Third Humeral Fractures: – Humeral Mid-Shaft Frx are also amenable to the posterior approach if the formal approach is modified (see below); … Read more
– Discussion: – indicated for displaced surgical neck, 3 part, and 4 part fracture; – deforming forces: – pectoralis major pulls the shaft medially, anteriorly and internally rotates; – supraspinatus abducts the head fragment in two part fractures; – w/ greater tuberosity is fracture, it will be pulled superiorly … Read more
– Discussion: (see olecranon frx menu) – indicated for comminuted olecranon frx and frx which occur at or distal to the coronoid process; – if frx extends distally past midpoint of trochlear notch, it no longer represents only a disruption of the triceps mechanism but also comprimises the stability of elbow in withstanding varus & … Read more
