Tendon Laceration Flashcards
What extensor tendons are prone to direct trauma on the forelimb?
Common and lateral digital extensors
What extensor tendons are prone to direct trauma on the hindlimb?
Long and lateral digital extensors
What is the best modality for diagnosing a tendon laceration?
Ultrasound
Why is flexor tendon laceration prognosis worse than extensor tendon laceration?
Flexor tendons are weight-bearing
Are flexor or extensor tendon lacerations more common?
Flexor tendons
How do you treat extensor tendon injuries?
Palmar aspect PVC pipe splint w/bandage
What is the goal for stabilizing an extensor tendon injury?
Prevent horse from knuckling when it walks
Which flexor ligament is usualy the last to rupture?
Suspensory ligament
“Toe up” is a sign of _____ rupture
DDF
What is a concern for treating flexor tendon injury?
Contralateral limb laminitis
Treatment includes wound management and splinting w/bandage
Extensor tendon injury treatment
Treatment includes splinting, casting, corrective shoeing, or surgical intervetion
Flexor tendon injury treatment
Which limb can get an epidural catheter?
Hindlimb
Minimizes tendon gap, restores gliding function, reduces adhesions, and preserves vasculature
Tenorrhaphy
When do you suture the tendons back together?
> 50% lacerated
What are the 3 options for suturing tendons back together?
Locking loop suture, 3 loop pulley, 6 strand savage
Which tendon suturing technique is the easiest, provides good strength, and leaves the least amount of exposed suture?
Locking loop suture
What cast do you place post-op for a hind limb? For a forelimb?
Hindlimb = distal limb cast Forelimb = full limb cast
Why does the hindlimb need a full limb cast post-tenorrhaphy?
Stay apparatus needs support since it provides tension for the whole limb
What is a risk of a full limb cast?
Increased risk for peroeus tertius rupture
How long must you stall rest a tenorrhaphy patient post-op?
2-3 months after cast removal
What is the total recovery period for a tenorrhaphy?
8-12 months
What is the prognosis of a flexor tendon injury to return to athleticism?
Guarded 45-59%
What is the px of an extensor tendon injury to return to athleticism?
Good 72-80%
What are complications of tendonitis?
Necrosis, sepsis, proud flesh, acquired FLD
