– 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
– See: PIN – Inciting causes: – radiocapitellar joint ganglions and synovitis – congenital tightness of ligamentous arcade of Frohse; – include poorly placed screws for fracture fixation – PIN is vulnerable during ORIF of proximal radius; – in 25% … Read more
– See: Autograft Discussion – PreOp Planning: – if patient has undergone previous bone graft harvests, consider CT scan to determine amount of remaining bone left in the crest; – Technique: – ensure that appropriately sized self retaining retractors are available; – straight longitudinal incision is made over posterior superior … 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 … Read more
– is derived from the Lumbrosacral Plexus – arises from posterior branches of S1, S2 & anterior branches of S2, S3; – travels thru greater sciatic foramen; – accompanies Sciatic Nerve in gluteal region; – continues downward in midline deep to the fascia lata, giving off branches that supply the skin of the posterior thigh.
– 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
– Discussion: – typically the posterior column remains intact w/ a burst frx; – w/ severe injury, anterior angulation may damage posterior ligamentous ligament complex, creating an unstable burst frx; – w/ further axial loading, inferior facets of upper vertebrae wedge apart superior facets and pedicles of the fractured … Read more
– Anatomy: – three posterior divsions of brachial plexus form posterior cord: (C5 , C6 , C7, C8, T1) – upper subscapular nerve to subscapularis – thoracodorsal to latissimus dorsi – lower subscapular nerve to subscapularis and teres major … Read more
– See: – Classification and Column Theory – Posterior Wall Fractures – AO Foundation Posterior Column Frx – Discussion: – posterior column extends from obturator foramen thru posterior aspect of the wt bearing dome of acetabulum & then obliquely through greater sciatic notch; – frx 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
