bone of upper limb can be divided into 4 main groups
|
1.hand & wrist-phalanges 14
metacarpals 5 carpals 8 2. forearm - radius and ulna 3. arm - humerus 4. shoulder girdle-clavicle, scapula, proximal humerus |
|
|
most dital bones of the hand
|
phalanges distal, middle proximal
|
|
|
the bones of the palm are the
|
metacarpals
|
|
|
the bones of the wrist are the
|
carpals
proximal row (r>u)scaphoid, lunate, triquetrum, pisiform, distal row (r>u)trapezium, trapezoid, capitate, hamate |
|
|
the parts of the metacarpal are the
|
head body base
|
|
|
joints of the hand
|
thumb- interphalangeal joint
mcp joint fingers 2-5 dip joint pip joint mcp joint |
|
|
radius and ulna articulate where?
position where radius and ulna do not cross? which bone is medial |
-proximal radioulnar joint and at the distal radioulnar joint
-AP(supinated) palms up ulna in anatomical position |
|
|
wrist joint movement:
ulnar deviation radial deviation |
is to see scaphoid (it opens up the radius side)
shows hamate and pisiform,(it opens up the ulna side) |
|
|
bennet's fracture
|
fracture at base of 1st metacarpal
|
|
|
boxer's fracture
|
transverse fracture @ metacarpal neck 5th metacarpal
|
|
|
colles fracture
|
transeverse fracture @ distal radius/displaced posteriorly
(usually ulnar styloid fracture) |
|
|
Smith's fracture
|
opposite of colles' fx
transverse of the fx of the distal radius displaced anteriorly |
|
|
Carpal bones
1.boat shape 2.moon shape 3.pyramidal shape 4.pea shape 5.sided irrregular 6.edge shape 7.large bone 8.hook-like |
1.scaphoid
2.lunate 3.triquetrum 4.pisiform 5. trapizium 6. trapezoid 7. capitate 8. hamate |
|
|
radius articulates with which 2 carpal bones
|
scaphoid and lunate
|
|
|
the wrist is what type of joint
|
synovial classification
diarthrodial freely moving |
|
|
anterior and posterior fat pads are useful diagnostic indicators but the elbow must be
|
1. flexed 90 degrees
2. true lateral position 3. optimum exposure techniques |
|
|
humerus
|
is the largest and longest in the upper limb
proximal humerus: head anatomic neck, lesser tubercle , greater tubercle, interbercular groove, surgical neck, body, & deltoid tuberosity Shoulder girdle: clavicle, scapula and proximal humerus |
|
|
what on the humerus is most often broken
|
surgical neck
|
|
|
hill-sachs defect
|
compression fx of the humeral head = anterior dislocation
|
