Tendons join
Muscle to bone
Tendons consist of fascicles of collagen bundles which are covered by a layer of endotenon
Fasicles are then covered by …
The whole tendon is covered with …
paratenon
epitenon
How do tendons* get blood supply
*but are relatively avascular
Network of blood vessels in the layer of paratenon
Movement of tendons keeps them healthy as immobility does what to them
reduces water content & glycosaminoglycan concentration and strength
Common site of tendon degeneration
Achilles tendon
Name an example of tendon inflammation
de quervain’s stenosing tenovaginitid
What is enthesiopathy
Inflammation at insertion of tendon to bone
What is traction apophysitis, e.g. Osgood schlatter’s disease
- often called growing pains
- common in young active boys
Excessive load or tension on the attachment site or apophysis leading to pain, e.g. during rapid growth periods or poor sports technique
What is an avulsion fracture
where the tendon insertion is actually pulled off the bone
Ways of testing achilles tendon rupture
Simmond’s (squeeze) test
