The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. [5] A severe ankle dorsiflexion force may result in a Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling.

The cysts may intrude into the spine, which may cause pain and dysesthesia in distant extremities. [ 20 ] Cystic adventitial disease , in which a cyst occurs within the popliteal artery near the knee, has been proposed recently to occur by an articular mechanism, with a conduit leading from the joint, similar to the development of ganglion ...
A burst cyst commonly causes calf pain, swelling and redness that may mimic thrombophlebitis. A specimen from a cadaver of a Baker's cyst in popliteal space Baker's cyst on axial MRI with communicating channel between the semimembranosus muscle and the medial head of the gastrocnemius muscle.
The achilles tendon, tendo calcaneus attaches distally to the calcaneual tuberosity, and arises superiorly from the triceps surae complex of the gastrocnemius and soleus muscles. Achilles tendon at foetus. The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower
The next step of identifying the POL femoral attachment is done by locating the gastrocnemius tubercle (2.6 mm distal and 3.1 mm anterior to the medial gastrocnemius tendon attachment on the femur). If the posteromedial capsule is not intact, the POL attachment site is located 7.7 mm distal and 2.9 mm anterior to the gastrocnemius tubercle.
Medial gastrocnemius perforator, draining into the gastrocnemius vein; Fibular perforators, usually two, one superior near the lateral aspect of the knee and one inferior at the lateral aspect of the ankle; When the valves of perforator veins become incompetent they can cause venous reflux when the muscles contract.
The superficial portion (the gastrocnemius) gives off two heads attaching to the base of the femur directly above the knee. The deep (profundus) mass of muscle (the soleus) forms the remaining head which attaches to the superior posterior area of the tibia. The triceps surae is innervated by the tibial nerve, specifically, nerve roots L5–S2.
The traumatic bone cyst, also referred to as a simple bone cyst or hemorrhagic cyst, is a pseudocyst that most commonly affects the mandible of young individuals. It is a benign empty or fluid-containing cavity within the mandible body that does not have evidence of a true epithelial lining.
