Pudendal nerve entrapment ( PNE ), also known as Alcock canal syndrome, [1] [2] is an uncommon [1] [3] [4] source of chronic pain in which the pudendal nerve (located in the pelvis) is entrapped or compressed in Alcock's canal. There are several different types of PNE based on the site of entrapment anatomically (see Anatomy ). [5] .
: 655 After repeated traction of the pudendal nerve, it starts to be replaced by fibrous tissue with subsequent loss of function. Pudendal nerve entrapment, also known as Alcock canal syndrome, is very rare and is associated with professional cycling.

What is a pudendal nerve?
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] . It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
Pudendal nerve entrapment can occur when the pudendal nerve is compressed while it passes through the pudendal canal. [2] History. The pudendal canal is also known as Alcock's canal, named after Benjamin Alcock. [3] Additional images. The superficial branches of the internal pudendal artery.
Nerve testing such as EMG and NCS can be done but there is little evidence it's helpful. Differential diagnoses include pudendal nerve entrapment, ischiofemoral impingement, greater trochanter ischial impingement, and ischial tunnel syndrome. Exclude hip/spine
The perineal nerve is a branch of the pudendal nerve. It lies below the internal pudendal artery. It accompanies the perineal artery. It passes through the pudendal canal for around 2 or 3 cm. Whilst still in the canal, it divides into superficial branches and a deep
The dorsal nerve of the penis is the deepest of three divisions of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm .
