Achilles Tendon Flashcards
The Achilles tendon is shared between which muscles of the posterior leg?
Gastrocnemius and the soleus
What does the Achilles tendon connects the two muscles to?
The calcaneus
What is the thickest tendon in the human body?
The achilles tendon
What is the Achilles tendon a distal attachment site for ?
The soleus
The gastrocnemius (medial and lateral heads)
What is the insertion of the Achilles tendon?
The posterior surface of the calcaneus
What movement is the achilles tendon involved with?
Plantar flexion
What tensile load can the achilles tendon withstand?
10x body weight
What does the anatomy of the achilles tendon provide for when running?
Elasticity (recoil)
Shock absorbance in the foot
Name the two main blood vessels of the achilles tendon
Posterior tibial artery
Peroneal artery
What sections of the achilles tendon does the posterior tibial artery supply?
The proximal and distal sections
What sections of the achilles tendon does the peroneal artery supply?
Supplies the middle section
Does the achilles tendon have relatively good or bad bloody supply?
Which section has a particularly low blood supply?
Relatively bad blood supply.
The midsection - this is where you see a lot of injuries take place.
The Achilles tendon is innervated by…
Mainly the sural nerve, with minor contributions from smaller branches of the tibial nerve.
What type of injuries is the Achilles Tendon susceptible to?
And what are the most common?
Overload
Achilles tendinopathy (55-65%)
Insertional issues account for 25-35% of cases
