Upper Limb Flashcards
Abductors of shoulder
Supraspinatus
Deltoid (15-90°)
Trapezius (90-100)
Serratus anterior (90-100)
Initiator is shoulder abduction
Supraspinatus (0-15°)
Number of tendons in carpal tunnel
9 (4+4+1) super+profundus+policis
Closest structure to hamate bone in carpal tunnel
Tendons of flexor digitorum profunda
Mnemonic for artery and nerve in upper limb
Nerve guards artery
Relation ulnar artery and ulnar nerve
U. Nerve is U. To U. Artery
Relation of radial artery with radial nerve
R. Nerve is R. To R. Artery
Which structure is pierced by CEPHALIC VEIN before termination
Pierces clavipectoral fascia before termination into axillary vein
What to do if sniff box tenderness without X ray abnormality
Redo x-ray are 1-2 wks
Blood supply of scaphoid bone
Radial artery from distal end
What carpal bones may be dislocated associated with scaphoid fracture
Lunate bone
Risk of transverse fracture of scaphoid bone
Non union
Initial Mx of any open fracture
Admission and Surgical debridement
Percentage of carpal and scaphoid fracture
80% in men
80% in scaphoid
Phalen ,tinel,froment sign for which nerves
Median
Median
Ulnar
Nerve of thenar
Median except adductor pollicis (ulnar-froments test)
Hypo thenar nerve
Ulnar
Surgical use of palmaris Longus
Tendon graft
Anterior interosseous nerve supply and comes from where
From medial nerve
Supply long flexors middle and index (injury will cause loss of pencil movement)
Lac of cuteneous supply
Inquiry of median nerve proximal to flexor retinaculum
Loss of flexor pollicis brevis, opponens pollicis,1st and 2nd lumbricals
Nerve to abductor pollicis Longus
Posterior interosseous nerve(a branch of radial nerve)
Which muscle helps trapezius during shoulder abduction above 90°
Serratus anterior
smallest muscle in the rotator cuff with function
Supraspinatus
responsible for initiating shoulder abduction.
Degrees related with shoulder abduction
Initiator is supraspinatus from 0°
Then deltoid upto 90°
Above 90° by trapezius and Serratus anterior
