In the early 1900s, dysfunction of the sacroiliac joint was a common diagnosis associated with low back and sciatic nerve pain. [18] However, research by Danforth and Wilson in 1925 concluded that the sacroiliac joint could not cause sciatic nerve pain because the joint does not have a canal in which the nerves can be entrapped against the ...
The sciatic nerve is highly mobile during hip and leg movements. [32] [33] Any pathology which restricts normal movement of the sciatic nerve can put abnormal pressure, strain, or tension on the nerve in certain positions or during normal movements. For example, the presence of scar tissue around a nerve can cause traction neuropathy. [34]

A heavily scrutinized anatomic variation involves sciatic nerve branching around the piriformis using the 6 category classification first described by Beaton and Anson.

Occasionally imaging and electrophysiology studies aid in the diagnosis. Timely diagnosis is important as untreated chronic nerve compression may cause permanent damage.
