- What it is
- A surgical study of 8 patients with cubital tunnel syndrome that measured pressure beside the ulnar nerve with the elbow extended and flexed during operations.
- How much weight it carries
- Peer-reviewed, but only eight elbows, all operated on, with an average age of 62. The result shows raised pressure in people who already have the syndrome, so it does not show cause in healthy people.
Facts taken from this source
- During surgery on patients with cubital tunnel syndrome, the average pressure 1 cm into the tunnel was 105 mm Hg with the elbow flexed.
“The average pressures within the cubital tunnel at 1, 2, and 3 cm distal to the proximal edge of the cubital tunnel retinaculum with the elbow flexed were 105, 29, and 18 mm Hg, respectively.” (Results)
