| what is a smiths fx | anterior fx of the distal radius |
| how do you locate scaphoid | 3/4 inch distal and medial to radial styloid process |
| AP forearm positioning | hand is supinated CR: mid-forearm epicondyle line parallel to IR want humerus and forearm in same plane |
| lateral forearm positioning | CR: mid forearm thumb up flex elbow 90 degrees |
| ap elbow positioning | CR: mid elbow epicondyles parallel to IR |
| radius and ulna are superimposed how much | 1/8 |
| lateral elbow positioning | CR: perpendicular to elbow joint hand and wrist in true lateral thumb up |
| lateral oblique elbow positioning | CR: mid elbow radial head is free of superimposition 45 degree hand supinated |
| medial oblique elbow positioning | CR: mid elbow 45 degrees olecranon and coronoid process |
| AP partial flexion elbow positioning | obtain two one with forearm parallel to IR or one with humerus parallel to IR CR: mid elbow |
| trauma axiolateral coyle method - radial head positioning | elbow flexed 90 degrees hand pronated CR: mid-elbow 45 degree angle to shoulder |
| coyle method - coronoid positioning | elbow flexed 80 degrees hand pronated CR: mid elbow 45 degree angle away from the shoulder |
| AP humerus positioning | CR: mid humerus epicondyles parallel to IR |
| Lateral humerus positioning | CR: mid humerus epicondyles perpendicular to the IR should include both joints |
| neutral humerus position | CR: mid humerus directed perp to IR trauma view- palm usually on outside of femur |
| transthoracic humerus positioning | aka lawrence side of interest closest to IR unaffected arm out of way on head CR: mid diaphysis directed through thorax/surgical neck orthostatic breathing technique CR can be angled 10-15 cephalic if you can't raise the arm |
| AP external shoulder positioning | external: epicondlyes are parallel to IR 1 inch inferior to coracoid process suspend respiration |
| what does the external shoulder demonstrate | greater tubercle in profile on the lateral aspect |
| AP internal shoulder positioning | epicondyles are perpendicular to the IR 1 inch inferior to coracoid process |
| Lawrence shoulder method positioning | supine shoulder raised 2 inches from table CR: medial 25-30 degrees |
| grashey shoulder pos | rotate 35-45 toward affected side CR: glenoid cavity 2 inches medial and 3 inches inferior to the lateral border of the shoulder |
| AP neutral trauma shoulder pos | CR: perpendicular to coracoid process demonstrates the greater tubercle rotated anteriorly but still lateral to lesser tubercle |
| PA oblique scap Y pos | 45 - 60 rotation toward affected side arm on stomach CR: perp to mid scapula |
| NEER pos | 45-60 anterior oblique CR: angle 10-15 caudal through the superior margin of the humeral head |
| neer demonstrates | dislocation and fx of proximal humerus and scap |
| AP scapula pos | pt is supine arm abducted to form a right angle with the chest CR: perpendicular to IR 2 inches inferior to coracoid |
| lateral scapula pos- anterior | 45-60 rotation toward the affected side CR: perpendicular to middle of vertebral border of the scapula |
| posterior oblique lateral scapula pos | rotate away from the affected side CR: middle of vertebral border of the scapula |
| what are the three borders of the scapula | vertebral, lateral, superior |
| what is the thickest border of the scapula | lateral |
| AP / PA clavicle | mid clavicle |
| why do a PA clavicle | limit dose and reduce OID |
| AP axial clavicle | mid clavicle 15-30 cephalic for AP 15-30 caudal or PA |
| the larger the pt the _ the angle for a clavicle | less |
| AC joints W and WO weights | 1 inch superior to jugular notch or midway between AC joints |
| where should the weights be for AC joints and they should be how many pounds | 10-15 lbs on the wrist |
| AP or AP axial toes POS | AP: 15 degree foam wedge AP axial: 15 cephalic angle CR: MTP joint of interest |
| oblique toes pos | rotate 30-45 degrees 1-3 toes is internal rotation, 4-5 is external rotation MTP of interest |
| Lateral toes pos | affected toe in lateral position MTP of interest |
| Tangential sesmoid positioning | dorsiflex plantar surface forms 15-20 angle from vertical CR: 1st MTP |
| what is the largest sesmoid bone | patella |
| AP axial foot Pos | 10 degrees posteriorly to the base of the 3rd metatarsal |
| IP joint classification | hinge / ginglymus |
| MTP joint classification | ellipsoidal / condyloid |
| TMT joint classifcation | gliding/plane |

| lateral oblique foot pos | base of the 3rd metatarsal 30-40 rotation |
| lateral foot positioning | CR: to the base of the 3rd metatarsal mediolateral is more common because it is easier for patient |
| will you be able to completely superimpose metatarsals for the lateral foot | no- because of transverse arch |
