Supraspinatus tendon

Question 1

Abbey JSAP 2021

Sound dogs undergoing CT of thorax

Answer 1

Supraspintus mineralisation found in 4%

Prevalence low in sound dogs, when compared to lame dogs - suggests that this could be a/w lameness

Question 2

Pownder VCOT 2023

MRI of 34 tendons of sound dogs

Answer 2

Significant reduction in collagen orientation in most central portion was found for every increased year in age - suggests a senescent change can be expected with supraspinatus tendon

Question 3

Piras Animals 2023

Sx splitting of tendon of insertion of non-mineralised supraspinatus tendinopathy in 27 dogs (compressing biceps) - described by Lafeunte VS 2009

Bardet VCOT 1999 - classification of biceps lesions
1- complete avulsion from origin
2- mid substance
3- tendinitis
4- bipartite
5- luxation
6- tenosynovitis

Answer 3

Histo found seveere myxomatous degeneration in all

Sx was effective - 88% resolution of lameness

4% major complications

Question 4

McDougall Frontiers 2018

U/S findings in 41 dogs treated with BMAC-PRP

Answer 4

Improvement in tendon size, fibre pattern and echogenecity

Question 5

Kern Frontiers 2023

U/S appearance of supraspinatus and biceps 30 dogs following ESWT

Answer 5

Decrease in lameness but lameness score did not correlate with U/S score for either tendon

Dogs had improvement after tx with ESWT and REST
