Achilles Tendon Stress & Strain – Everything You Need To Know – Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video describes the anatomy of Achilles tendon.
Anatomy of the Achilles tendon. The Achilles tendon is located in the posterior ankle. The Achilles tendon is the strongest and thickest tendon in the body. It is formed from the soleus and gastrocnemius muscles. The Achilles tendon is inserted into the calcaneus bone.
The subcutaneous calcaneal bursa is found superficial to the Achilles tendon. The bursa lies between the skin and the distal aspect of the Achilles tendon. There is also a subtendinous calcaneal bursa located deep to the Achilles tendon. This bursa is located between the Achilles tendon and the calcaneal bone. Inflammation of one or both of this bursa can cause pain in the posterior heel or ankle.
The Achilles tendon is prone to tear or rupture and most of the ruptures occur above the calcaneal insertion of the tendon.
Like all tendons the Achilles tendon doesn’t have great vascularity. The watershed zone is a part of the tendon that has the worst blood supply. This is a narrow area in width between 2-6 cm proximal to the calcaneus.
The Achilles tendon is prone to tendonitis or tendon rupture in this area due to limited blood supply. When the Achilles tendon ruptures within this area, the result may be similar to pulling rope. This injury is also referred to as the weaken warriors injury. The injury typically occurs if over performing or overdoing a physical activity. The injury also occurs more in men aged 30-40 years.
The mechanism of injury for rupture of the Achilles is usually from an eccentric load on a dorsiflexed ankle with knee extension. The strain placed on the tendon less than 4% is within the normal limits of the physiological load. The fibers return to the original configuration when the load is removed. Starin between 4-8% lead to microscopic failure. Starin beyond 8% results in macroscopic failure and rupture of the Achilles tendon.
The Thompson test is performed in order to make a diagnosis of Achilles tendon tear.

شكرا دكتور .. مصري ولا من أي بلد؟
I LOVED this video. Finally, a simple explanation. I'd like to see a video featuring a repair using the FHL from the big toe repair.
More in men age 30 to 40 years old or people? Just wondering if any women tear their achilles.
my tendon cut is 13 Dec 2017 today date is 2 Feb 2018 can I walk
As a gymnast, this is the most common place I end up injury. I usually tumble through the pain… surprised i haven't broken my foot yet
Here's the link:https://www.amazon.com/Treat-Your-Own-Achilles-Tendinitis/dp/1457510928/ref=pd_sim_14_4?_encoding=UTF8&pd_rd_i=1457510928&pd_rd_r=106EP8AE0VXB4HSAQMH4&pd_rd_w=M6DXu&pd_rd_wg=epnnI&psc=1&refRID=106EP8AE0VXB4HSAQMH4
Oum, i got a arrow shot through my Achilles' tendon!, now i can't fight anymore.
only God can say if I can be able to play soccer again, I'm just 20 an I got Achilles tendon ruptured. God please safe my career.
'And I can't stand on only one leg!'
Is the right or left foot?

Informative and fun – thanks!
