styloid process of radius, radial carpal bone
replacement of a medial collateral ligament at the carpus is done so by placing bone screw at what 2 locations?
styloid process of ulna, ulnar carpal bone
replacement of a lateral collateral ligament at the carpus is done so by placing bone screw at what 2 locations?
palmar fibrocartilage, palmar ligaments
hyperextension injuries of the carpus result in tearing of what 2 types of structures?
plantigrade
stance that a dog is standing in with a hyperextension injury of the carpus
partial carpal arthrodesis, pancarpal arthrodesis
2 possible surgical treatments for a hyperextension injury of the carpus
antebrachiocarpal
in which joint of the carpus does the most carpal movement occur?
carpometacarpal
in which joint of the carpus do hyperextension injuries most commonly occur?
dorsal
when performing a pancarpal arthrodesis, a DCP is applies to what surface?
middle carpal, carpometacarpal
when performing a partial carpal arthrodesis, what 2 joints are fused using pins or T plates?
suture prostheses, bone screws, washers
3 materials used to replace collateral ligaments of the tarsal joint
tibiotarsal arthrodesis
procedure done for severe comminuted intraarticular fractures of the tarsus (also for severe DJD, chronic instability, and sciatic nerve plasty)
long digital extensor
in surgical correction of sciatic nerve palsy, a tibiotarsal arthrodesis is combined with transposition of what tendon?
2
when doing a tibiotarsal arthrodesis the tibia and talus are joined with how many lag screws?
positional
when doing a tibiotarsal arthrodesis what type of screw is placed from the tibia to the tuber calcis?
hyperflexion
with rupture of the common calcanean tendon, will there be hyperextension or hyperflexion of the tarsus?
locking loop
type of suture pattern used to repair common calcanean tendon ruptures
external fixator, positional screw
2 ways to immobilize the tarsus following repair of a ruptured common calcanean tendon
tuber calcis
if there is insufficient common calcanean tendon distally for suture repair, the tendon can be sutured through a tunnel in what bone?
medial ridge of the talus
most common location of OCD in the tarsus
hyperextension
with OCD of the talus, will there be hyperextension or hyperflexion?
conservatively
is it more appealing to repair OCD in the tarsus conservatively or with an arthrotomy?
