The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...
The sural communicating nerve (SCN) (peroneal communicating branch of the common fibular nerve) is a separate and independent nerve from both the medial and lateral sural cutaneous nerves, often arising from a common trunk of the common fibular nerve [1] [2] The primary purpose of the sural communicating branch is to provide the structural path for transferring tibial nerve fascicular ...
This nerve also supplies the tibialis posterior muscle, superior tibiofibular joint, tibia bone, interosseous membrane of leg, and the inferior tibiofibular joint. [1] Cutaneous branches - Tibial nerve also gives off a cutaneous nerve called the medial sural cutaneous nerve from the middle of the popliteal fossa and exits at the inferior angle ...
She originated the term sural nerve complex to fully encompass all contributions to the terminally named sural nerve (and later lateral dorsal cutaneous nerve). Further research would go on to use the sural nerve complex terminology to discuss the lateral sural cutaneous nerve, the medial sural cutaneous nerve, the sural communicating nerve and ...
The medial sural cutaneous nerve originates from the posterior aspect of the tibial nerve of the sciatic nerve. [2] [3] It descends between the two heads of the gastrocnemius muscle. [2] [3] Around the middle of the back of the leg, it pierces the deep fascia to become superficial. [3] It unites with the lateral sural cutaneous nerve to form ...
Another branch observed, that is mentioned in passing in previous literature is the medial branch of the lateral sural cutaneous nerve. [3]In a 2021 study by Steele et al. (Annals of Anatomy), a medial branch of the lateral sural cutaneous nerve was observed in approximately 36% of lower extremities dissected (n=208) with an average diameter of 1.47 ± 0.655 mm with a 95% CI of 1.31 – 1.625 mm.
Common fibular nerve (blue) - labeled as "peroneal nerve". Also Lateral sural cutaneous nerve. Saphenous nerve (pink), a branch of the femoral nerve. Superficial fibular nerve (yellow) - labeled as "superficial peroneal nerve". Also Medial dorsal cutaneous nerve. Sural nerve (brown). Also Medial sural cutaneous nerve.
