LASx Exam 1: Tendonitis Flashcards
Superior/Proximal Check Ligament supports the ______
and attaches to the back of the radius
SDF
Inferior/Distal Check Ligament supports the ______ and
attaches to the back of the cannon bone (MC3)
DDF
________ surrounds fascicles and wraps around the entire tendon
Endotenon
________ surrounds the endotenon and tendon
Epitenon
___________ surrounds tendons that are NOT in a sheath
and OUTSIDE a synovial cavity
Paratenon
What are the regions of the tendon stress-strain curve
from start to failure?
Toe region - Elastic region - Yield point - Plastic region - Failure
TEY PF
Tendons can extend _______% before rupture
12 - 20%
Scar tissue, formed with Type 3 collagen results in a
less ELASTIC tendon with an increased ______ region
plastic
Tendons in a tendon sheath are _______ efficient at healing
than tendons outside a sheath
LESS
What are the 3 causes of tendonitis?
Overuse
Infection
Traumatic injury
These 2 tendons/ligaments are the most prone to injury due to
having the most load during heel strike
SDFT and SL
The most common tendon/ligament to tear
WITHIN a synovial cavity is the ________ in the FORElimb
and the ________ in the HINDlimb
DDFT- forelimb
Manica Flexoria- hindlimb
Core lesions are seen most commonly in this tendon
SDFT
Tendonitis within a tendon sheath is known as
tenosynovitis and can lead to this condition
Annular ligament constriction
On physical exam, you see bowing of the palmar contour of
the distal limb in a horse. What is causing this?
Tendonitis!
This is the best tool for diagnosing tendonitis
ULTRASOUND
What type of probe is used for diagnosing tendonitis with
and ultrasound?
7.5 - 12 MHz LINEAR transducer
How does the view of the tendons change at the level
of the fetlock on Ultrasound?
The DDFT becomes BILOBED at the pastern (P1-P2 area)
When taking measurements when ultrasounding a limb
for tendonitis, you should measure the distance between
the transducer and the ___________
ACCESSORY CARPAL BONE
When ultrasounding a limb for tendonitis,
______ injuries will be HYPOechoic, where as
________ injuries will be HYPER or HETEROechoic
Acute- HYPO
Chronic- HYPER/HETERO
A reduced striated pattern indicates _______ tendon injury
where as an
irregular striated pattern indicates ______ tendon injury
REDUCED striated = ACUTE
IRREGULAR striated = CHRONIC
T/F:
You suspect a tendon injury where the DDFT inserts onto P3.
The best diagnostic tool to use here is Ultrasound
FALSE!
This is blocked by the hoof capsule, so will have to use MRI
What type of NSAID is given to horses with tendonitis or tendon injuries?
Phenylbutazone
T/F:
Blood and bone marrow concentrates can be therapeutic in
equine tendonitis, desmitis, and osteoarthritis
TRUE
Adipose derived mesenchymal stem cells differentiate into
musculoskeletal tissue but are INFERIOR to
__________
Bone Marrow
What are the two types of desmotomy procedures
used in equine tendon repair?
Superior Check Desmotomy
and
Annular Ligament Desmotomy
Inflammation of the ligament is known as
DESMITIS
