Tendon Injuries Flashcards
Where do tendons originate
Bone
what is the name of the tendinous insertion into bone
sharpey fibres
What type of collagen in tendon
Type 1: Triple Helix
Collagen bundles are covered by what in tendon
Endotenon
fascicles are covered by what in tendon
Paratenon
Tendon is covered by what in tendon
epitenon
Tendon Blood supply
vinculum
Tendons are connected to sheath by
vincula
What is a precursor to achilles tendon rupture?
Degeneration
De Quervain Stenosing Tenovaginitis in Hand affects which tendons
EPB and apl at radial aspect
De Quervain Stenosing Tenovaginitis in Hand diagnosis
positive finklestein test
what is enthesiopathy
Inflammation at insertion to bone
usually at muscle origin rather than tendon insertion
what is traction apophysitis also known as
Osgood Schlatter’s disease
where does traction apophysitis/osgood schlatter disease occur
insertion of patellar tendon into anterior tibial tuberosity
who does traction apophysitis/osgood schlatte happen to
adolescent active boys
recurrent load
inflammation
What is Avulsion and Bone Fragment
Fail at insertion
Load Exceeds Fail Strength while muscle contract
Mallet Finger what is this
forced flexion of extended finger
Mallet finger happens where
insertion of extensor tendon into dorsum of base of distal phalanx of finger
Treatment for Avulsion
Reattach Tendon
Fixation
Retraction Tendon
Achilles Tendon is an example of what type of rupture
Intrasubstance
Mechanism of achilles Tendon rupture
pushing off with weight bear forefoot while extend knee joint eg sprint start
unexpected dorsiflexion of ankle
violent dorsiflex of plantar flex foot
How to test for Achilles Tendon rupture
Positive Simmond Squeeze Test
Palpable Tender Gap
Where does musculotendinous junction tear occur
medial head of gastrocnemius at musculotendinous junction with Achilles tendon
treatment of musculotendinous junction tear
mobilise
splint
healing will not occur in interarticular
operation
high risk rerupture
ends cannot be opposed
Laceration in tendon common where
Finger Flexors FDS and FDP
Laceration in tendon common when
Males
