– See: Multisegmented Hook Instrumentation – Discussion: – are excellent for the treatment of thoracic or thoracolumbar frx; – these rods can be used with hooks and/or screws; – if hooks are used, do not place them adjacent to any area of canal comprimise; – because rods … Read more
– Discussion: – the Coventry type of HTO, creates an osteotomy above the tibial tubercle; – in choosing a closing wedge osteotomy, the surgeon should be sure that the major deformity is on the tibial side (vs femoral side); – the disadvantages of this type of osteotomy include possible … Read more
Origin: tip of coracoid process on scapula; Insertion: middle of medial border of humerus, opposite deltoid tuberosity; action: horizontal flexion and adduction of the humerus at the shoulder; synergists: pectoralis major, biceps brachi, and anterior deltoid; nerve supply: musculocutaneous, C6, C7; – Surgical Hazards: – profunda gives off muscular branches, usually gives rise to … Read more
Anatomy: coracoid process can be palpated thru anterior deltoid muscle one to two finger breadths below outer portion of clavicle; one finger breadth lateral to coracoid is the GHJ; provides a palpable guide to deltopectoral groove; serves as an anchor for coracoid muscles (coracobrachialis & short head of biceps) that separate lateral safe side from medial … Read more
– Discussion: – refers to retropubic vascular communication between either the external iliac (or deep epigastric vessels) and the obturator artery; – medial window (of ilioinguinal approach) is used to identify any possible communication between obturator system and external iliac or inferior epigastric system (instead of the internal iliac artery); – inferior epigastic artery: – … Read more
– Discussion: – coronoid helps to resist varus stress and posterior elbow subluxation (radial head also resists posterior subluxation); – pivotal role as an anterior buttress; – at least 50% of the coronoid must be present for the ulno-humeral joint to have normal function (i.e., for joint to be stable); … Read more
– Discussion: – Delivers preset tidal volume at preset rate. – No allowance is made for gas flow upon spontaneous effort by patient; – Usually reserved for intraoperative use with anesthesia – Requires heavy sedation or paralysis; – Assist controlled mechanical ventilation: (ACMV) – Ventilator delivers a preset tidal volume each time the patient makes … Read more
