Pudendal nerve entrapment is an example of nerve compression syndrome. Pudendal neuralgia (PN) refers to neuropathic pain along the course of the pudendal nerve and in its distribution. This term is often used interchangeably with pudendal nerve entrapment. However, it has been suggested that the presence of symptoms of pudendal neuralgia alone ...
The coccygeal plexus gives rise to the anococcygeal nerve. [2] The coccygeal plexus is distributed to the coccygeus muscle, part of the levator ani muscle, the sacrococcygeal symphysis, and (via the anococcygeal nerve) a small area of skin between the tip of the coccyx, and the anus. [1]
It runs from the sacrum (the lower transverse sacral tubercles, the inferior margins sacrum and the upper coccyx [1]) to the tuberosity of the ischium. It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which ...
In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm.
The name coccyx is derived from the Greek word for 'cuckoo' due to its beak-like appearance. The coccyx itself is made up of three to five vertebrae, some of which may be fused together. The ventral side of the coccyx is slightly concave whereas the dorsal aspect is slightly convex.
The fibers pass downward and backward to the middle line of the floor of the pelvis; the most posterior are inserted into the side of the last two segments of the coccyx; those placed more anteriorly unite with the muscle of the opposite side, in a median fibrous ridge called the anococcygeal body or raphe, which extends between the coccyx and ...
