Sural Nerve Complex
The sural nerve complex are the contributing nerves that form the sural nerve. There are eight documented anatomic variations of the sural nerve complex. Origins In 1987, an orthopedic surgeon named Dr. Ortiguela of the Mayo Clinic conducted a cadaveric study in which the posterior leg was exposed. She was studying the nerve fascicle contribution of each of the nerves that contribute to the final formation of the sural nerve to find better nerve donors. 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 sural nerve proper. Morphology Recent cadaveric research shows that there are potentially ''six to eight variations'' of the sural nerve complex. Ramakrishnan et al. reviewed 39 cadaveric ...

Mayo Clinic
The Mayo Clinic () is a nonprofit American academic medical center focused on integrated health care, education, and research. It employs over 4,500 physicians and scientists, along with another 58,400 administrative and allied health staff, across three major campuses: Rochester, Minnesota; Jacksonville, Florida; and Phoenix/Scottsdale, Arizona. The practice specializes in treating difficult cases through tertiary care and destination medicine. It is home to the top-15 ranked Mayo Clinic Alix School of Medicine in addition to many of the highest regarded residency education programs in the United States. It spends over $660 million a year on research and has more than 3,000 full-time research personnel. William Worrall Mayo settled his family in Rochester in 1864 and opened a sole proprietorship medical practice that evolved under his sons, Will and Charlie Mayo, along with practice partners Stinchfield, Graham, Plummer, Millet, Judd, and Balfour, into Mayo Clinic.

Nerve Fascicle
A nerve fascicle, is a bundle of nerve fibers belonging to a nerve in the peripheral nervous system. A nerve fascicle is also called a fasciculus. A nerve fascicle is enclosed by perineurium, a layer of fascial connective tissue. Each enclosed nerve fiber in the fascicle is enclosed by a connective tissue layer of endoneurium. Bundles of nerve fascicles are called fasciculi and are constituents of a nerve trunk. A main nerve trunk may contain a great many fascicles enclosing many thousands of axons. In the central nervous system (CNS) a bundle of nerve fibers is called a nerve tract, and in neuroanatomy different tracts in the spinal cord are bundled into fasciculi such as the medial longitudinal fasciculus. In the spinal cord fasciculi are bundled into columns called funiculi such as the anterior funiculus. See also * Epineurium * Nervous tissue Nervous tissue, also called neural tissue, is the main tissue component of the nervous system. The nervous system regulates and ...

Sural Nerve
The sural nerve ''(L4-S1)'' is generally considered a pure cutaneous nerve of the posterolateral leg to the lateral ankle. The sural nerve originates from a combination of either the sural communicating branch and medial sural cutaneous nerve, or the lateral sural cutaneous nerve. This group of nerves is termed the sural nerve complex. There are eight documented variations of the sural nerve complex. Once formed the sural nerve takes its course midline posterior to posterolateral around the lateral malleolus. The sural nerve terminates as the lateral dorsal cutaneous nerve. Anatomy 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. 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 traveling parallel to the medial ...

Lateral Dorsal Cutaneous Nerve
The lateral dorsal cutaneous nerve is a cutaneous branch of the foot. This nerve is the terminal nerve portion of the sural nerve. The common convention for where the sural nerve transitions into the ''lateral dorsal cutaneous nerve'' is after the ''sural nerve'' wraps underneath the lateral malleolus. This turns into a dorsal digital nerve and supplies the lateral side of thfourth and fifth toe The course of this nerve influences the surgical approach to fixation of fractures of the fifth metatarsal The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the me ..., as the most direct surgical approach is at risk of damaging it.

Lateral Sural Cutaneous Nerve
The lateral sural cutaneous nerve of the lumbosacral plexus supplies the skin on the posterior and lateral surfaces of the leg. The lateral sural cutaneous nerve originates from the common fibular nerve''(L4-S2)'' and is the terminal branch of the common fibular nerve. Sural communicating branch One branch, the '' sural communicating nerve'' or colloquially known as the ''peroneal anastomotic'' (n. communicans fibularis), arises from sciatic origins near the head of the fibula, crosses the lateral head of the gastrocnemius to the middle of the leg, and joins with the medial sural cutaneous nerve to form the sural nerve Variation Another branch observed, that is mentioned in passing in previous literature is the medial branch of the lateral sural cutaneous nerve. In a 2021 study bSteele 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. ...

Medial Sural Cutaneous Nerve
The medial sural cutaneous nerve ''(L4-S3)'' is a sensory nerve of the leg. It supplies cutaneous innervation the posteromedial leg. Structure The medial sural cutaneous nerve originates from the posterior aspect of the tibial nerve of the sciatic nerve. It descends between the two heads of the gastrocnemius muscle. Around the middle of the back of the leg, it pierces the deep fascia to become superficial. It unites with the lateral sural cutaneous nerve to form the sural nerve The sural nerve ''(L4-S1)'' is generally considered a pure cutaneous nerve of the posterolateral leg to the lateral ankle. The sural nerve originates from a combination of either the sural communicating branch and medial sural cutaneous nerve, or .... Morphometric properties According to a large cadaveric study in which 208 sural nerves were dissected in their native position (bSteele et al. the medial sural cutaneous nerve was consistently present in most lower extremities.

Sural Communicating Branch Of The Common Peroneal Nerve
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 The primary purpose of the sural communicating branch is to provide the structural path for transferring tibial nerve fascicular components to the sural nerve. Anatomy The ''sural communicating nerve'' (colloquially the peroneal communicating nerve) is one of the components of thsural nerve complex( MSCN, LSCN,SCN). It travels in an inferomedial direction from its origins either as a terminal component of the LSCN or is considered a nerve that originates along a common trunk of the lateral sural cutaneous nerve. This particular nerve is best described by Dr. Huelke in 1958. ''Dr. Huelke'' took the original modern cadaveric studies (from the turn of the 20th century) and wrote a treatise titled "The origin of the peroneal co ...
