Скачать или смотреть Anatomy Of The Plantaris Muscle - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the plantaris muscle
The plantaris muscle arises form the lateral supracondylar ridge of the femur above the lateral head of the gastrocnemius muscle.. the plantaris muscle inserts into the medial side of the calcaneus. The plantaris muscle passes between the soleus and gastrocnemius muscles down to its insertion into the calcaneus. It lies within the superficial posterior lower leg compartment and its absent in about 10% of the population.
It allows plantar flexion of the foot and flexion of the knee.
It is innervated by the tibial nerve.
Contains high density of proprioceptive receptors end organs. This allows the plantaris muscle to provide feedback to the central nervous system regarding the position of the foot.
Muscle is mainly used by surgeons for tendon grafts, especially for Achilles tendon rupture to augment the repair. The plantaris muscle could be injured in association with an Achilles tendon rupture.
Thompson test: it may show inaccurate results if the plantaris is intact.
When rupture of the plantaris occurs, the patient may feel a sharp planataris tendon, the patient may feel a sharp stabbing pain at the back of the calf. The patient may also feel a “pop” similar to being struck from behind. Calf muscle will become swollen with significant bruising. The condition is often referred to as “tennis leg”. injury occurs due to eccentric loading on the ankle with the knee extended.
