Peripheral nerve entrapments are a relatively rare and heterogeneous group of nerve disorders encompassing a wide variety of etiologies and clinical presentations. These conditions can present significant diagnostic challenges, owing to both the variety of symptoms these patients display, along with the anatomic variation that exists between individuals. Precise knowledge of the anatomic course, the common motor and sensory distributions of each of the peripheral nerves, and judicious use of imaging or electrodiagnostic testing can greatly assist in arriving at a correct diagnosis. In this article, we discuss in detail the anatomy, clinical presentation, diagnosis, and treatment options for peripheral nerve entrapments of the lower extremity involving the sural, saphenous and common, superficial, and deep peroneal nerves.

UI	MeSH Term	Description	Entries
D007866	Leg	The inferior part of the lower extremity between the KNEE and the ANKLE.	Legs
D009408	Nerve Compression Syndromes	Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.

D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

D010543	Peroneal Nerve	The lateral of the two terminal branches of the sciatic nerve. The peroneal (or fibular) nerve provides motor and sensory innervation to parts of the leg and foot.	Fibular Nerve,Fibular Nerves,Nerve, Fibular,Nerve, Peroneal,Nerves, Fibular,Nerves, Peroneal,Peroneal Nerves
