1
Q

2 types of tendon injury

A

‘Percutaneous’ - laceration/penetration

‘Subcutaneous’ - strain, displacement

2
Q

Cause of over-strain injury - tendon

A

Sudden over-extension

Preceding tendon degeneration with superimposed sudden over-extension

3
Q

tendon - History

A

Usually a preceding intense period of exercise

Signs can be delayed

4
Q

tendon - Clinical examination

A

Lameness
Can be temporary
Lameness can be persistent for some tendon/ligament injuries

5
Q

Metacarpophalangeal joint extension changes

A

Decr - Reduced weight-bearing + Fibrosed (stiff) tendon

Increased with severe - SDFT/SL injuries

6
Q

Elevating toe

A

DDFT rupture

7
Q

Some areas difficult to palpate

A

Proximal SL in H/L

Pastern

8
Q

what to assess on palpation

A

Pain on palpation
Suppleness of tendons
Oedema

9
Q

Superficial digital flexor tendinopathy

A

Initial lameness (variable)
Pain on palpation
‘Core’ lesion on ultrasound

10
Q

Proximal suspensory desmitis - history

A

Lameness variable in degree

Acute or insidious onset

11
Q

Proximal suspensory desmitis - clinical signs - conformation

A

Straight hock

overextending MTP joint

12
Q

Proximal suspensory desmitis - clinical signs - lameness

A

Often lamer with the limb on the outside of a circle
Proximal MC/MT swelling - Variable, Medial palmar vein distension
Pain on palpation

13
Q

Proximal suspensory desmitis - diagnosis

A

Diagnostic analgesia

imaging - Ultrasonography, Radiography, (Gamma scintigraphy, MRI)

14
Q

Suspensory body and branch desmitis - ultrasonography

A
Branches need imaging from medial and lateral aspects 
Focal or generalised lesions 
Enlargement 
Periligamentar fibrosis very common 
Bilateral involvement common
15
Q

Suspensory body and branch desmitis - radiography

A

Concurrent bony abnormalities

16
Q

Desmitis of the accessory ligament of the deep digital flexor tendon (‘inferior check ligament’) - presentation

A

Swelling in the proximal metacarpal region

Dorsal to SDFT

17
Q

DDFT Tendinopathy

A

Usually within digital sheath or navicular bursa

18
Q

Intra-thecal tendon tears - location - DDFT

A

Usually lateral border

Forelimbs

19
Q

Intra-thecal tendon tears - location - Manica flexoria

A

Usually hindlimb

20
Q

Annular ligament syndrome (ALS)

A

Lameness - mild-moderate, minimally responsive to rest, occasionally irregular gliding of tendons
Distended digital sheath
notch at PAL level

21
Q

General principles of treatment for tendonitis

A

V.few evidence-based choices

based on tendon pathology + phases of tendon healing

22
Q

acute phase infl - clinical signs

A

Lameness
Pain on palpation
Heat
Swelling

23
Q

acute phase infl - Pathology

A

Haemorrhage

Inflammation

24
Q

acute phase infl - physical therapy

A

Application of cold (ice)
Compression
MCP joint support

25
Q

acute phase infl - rational treatment

A

minimise infl

26
Q

acute phase infl - medication

A

short-acting steroids - systemically/peritendinously

NSAIDs

27
Q

acute phase infl - surgery

A

Percutaneous tendon splitting

Possible to combine with intra-tendinous medication

28
Q

subacute reparative phase - Clinical signs

A

Reduction or absence of lameness
Resolution of signs of infl
Tendon still palpably enlarged and soft
Signs of re-injury if exercised too early

29
Q

subacute reparative phase - Pathology

A

Angiogenesis

Fibroplasia - ++ fibroblasts

30
Q

subacute reparative phase - rational treatment

A

promote fibroplasia

optimise organisation of scar

31
Q

subacute reparative phase - ongoing treatment

A

mobilisation

ultrasounds every 2-3 months
