Tensor fasciae suralis muscle
Citation, DOI and article data
- origin: may arise from the distal aspect of any of the hamstring muscles, in the majority of reported cases it originates from the distal semitendinosus muscle
- insertion: may insert into the posterior fascia of the leg, into the medial head of the gastrocnemius, or via a long thin tendon onto the superficial aspect of the Achilles tendon
- innervation: tibial nerve
A tensor fasciae suralis can usually be identified with ultrasound or MRI, which delineate an accessory muscle in the popliteal fossa, lateral to the semitendinosus tendon and posterior to the semimembranosus.
The accessory semimembranosus muscle, similar in location but arising from the semimembranosus, has also been described.
History and etymology
According to some reports, it is thought to have been first described by R A Bergman et al. in 1873 3.
