approaches Flashcards
deltopec approach
deltoid (axillary nerve) and pec major (medial and lateral pec nerves)
posterior approach to shoulder
infraspinatus (suprascapular nerve) and teres minor (axillary nerve)
main risks in posterior approach to shoulder
quadrangular space (stay above teres minor) and suprascapular nerve (avoid excessive medial retraction of infra)
anterolateral approach to humerus
proximal extension into deltopec, then lateral to biceps and between fibers of brachialis midhumerus (radial and MSC nerves) and between brachialis and BR (radial nerve) distally
anterior approach to AC fossa
superficial - biceps (MSC) and BR (radial), deep - PT (median) and supinator (PIN)
medial (Hotchkiss) approach to elbow
superficial - brachialis (MSC) and triceps proximally (radial) or PT distally (median), deep - split or elevate flexor pronator mass (median)
main risks in medial approach to the elbow
MABCN crosses field, ulnar nerve
lateral Kaplan approach to elbow
ECRB (radial/PIN) and EDC (PIN)
main risks in lateral Kaplan approach to the elbow
PIN, LUCL
posterolateral Kocher approach to the elbow
anconeus (radial) and ECU (PIN)
anterior/volar Henry approach to forearm
BR (radial) and PT proximally or FCR distally (median)
main risks of anterior Henry approach to forearm
superficial branch of radial nerve, radial artery, PIN
dorsal Thompson approach to forearm
ECRB (radial/PIN) and EDC proximally or EPL distally (PIN)
approach to ulna
ECU (PIN) and FCU (ulnar)
landmarks for lateral window of ilioinguinal approach
lateral to iliopsoas/iliopectineal fascia
