Arthroscopy Flashcards
which light source is best for scoping? why?
xenon - increase light intensity, higher color temp and greater visual clarity and color rendition
what are 2 options/styles of connection between scope and camera?
most common - spring loaded clip
direct coupling (glass on glass threaded interface)
for gravity flow irrigation, what is bag pressure set to?
60-100 mmHg
what is % collagen shrinkage when radiofrequency need?
15-25%
For scoping shoulder: what is treated with instrument on:
- caudal port
- caudolateral port
- cranial port
caudal - OCD 2 cm caudal and distal to acromion
caudolateral - ST injury of medial structures (glenohumeral ligament, subscapular tendon)
cranial - tendon BB
What are basic positions of egress, scope, and instrument in shoulder?
egress - craniocaudal midpoint of superior ridge of greater tubercle
scope - 1-2 mm cranial to acromion
instrument - caudal usually slight distal to acromion and 2 cm caudal
label and describe points of scope, instruments, egress placement for elbow scoping
egress - medial to olecranon // to medial surface
scope - distal and caudal to medial epicondyle (~5mm)
instrument - 1-2 cm cranial to arthroscope portal and caudal to MCL
what structures should your instrument portal watch out for?
MCL; median artery and nerve
with light post up in carpus, you see what surface? light post down?
light post up - radial carpal bone
light post down - distal radius
describe positions of ports for hip joint
egress - 3-5 o’clock R
scope - distal to GT
instrument - 3 o’clock position
describe ports for stifle
primary scope portal - lateral parapatellar region
egress - proximal patellar/trochlear region (medial)
instrument - medial parapatellar region
describe ports for tarsus scoping
egress - medial or lateral angled proximally
scope - medial or lateral side farthest from lesion on plantar side
to view dorsal, how do you position tarsus?
extension
to view plantar, how do you position tarsus?
flexion
