Tarsus

Question 1

Armstrong VS 2019

Retrospective

32 traumatic injuries of central tarsal bone in nonracing dogs

Answer 1

type 5 central tarsal # most common + luxation
most had concurrent tarsal #s

13% major, 3% catastrophic comp
comp a/w multiple tarsal #, specifically when calcaneus involved

Question 2

Buj VCOT 2021

retrospective
isolated articular talar #

Answer 2

38% rv sx

38% missed on rads
often lateral trochlear ridge # only, some both

Question 3

Easter VCOT 2021
type 5 central tarsal bone fractures
medial plate

Answer 3

low complications, bone healed

Question 4

Biggo Frontiers 2023

116 greyhounds with tarsal injuries

Answer 4

central tarsal > calcaneus >proximal intertarsal sublux

40% SSI, 50% explant (most often for SSI)
concurrent medial and lateral approaches was a/w increased risk of SSI

Question 5

Medial/lateral instability

Answer 5

Leuscher VS 2020 - Feline medial tarsal instability
Nicholson technique in cats

Gunstra JAVMA 2019 - Tarsometatarsal luxation stabilised with fig of 8 prosthetic lig in dogs and cats

Hammer VCOT 2020 - Tarsocrural luxation stabilised with internal repair + TA-ESF in cats
7% major comp requiring pantarsal

Worth VS 2024 - Tarsocrural luxation stabilised with temp CT screw + external coaptation in dogs
33% comp but most bandage related; all working dogs full work

Question 6

Panatarsal arthrodesis

Answer 6

Roch JSAP 2008
-33% major comp (15% plantar necrosis - medial plate)

Kulendra VCOT 2023
-Dorsal pedal artery intermetatarsal channel lies within proximal 25% of MT 3 -> avoid exiting dorsally between MT 2 and 3
-Lateral partial tarsal cases

Salvatierra JFMS 2017
-Dorsal + medial VCPs in cats

Anesi VS 2020
-Medial plating + additional fixation
-30% major, 3% catstrophic (97% success)
