Extra medullary Spinal Cord Compression:

1. Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extra medullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions.

2). Clinical manifestations vary with the anatomic site of the lesion and may include localized pain, weakness, sensory loss, incontinence, and impotence.

Extra Edge:

1). Hoffmann (or Tinel's sign) is a tingling sensation triggered by a mechanical stimulus in the distal part of an injured nerve.

2). This sensation radiates peripherally, from the point where it is triggered to the cutaneous distribution of the nerve.

3). The tingling response can be compared with that produced by a weak electric current, as in transcutaneous electrical nerve stimulation (TENS).

4). This unpleasant sensation is not a severe pain and does not persist
