Open the original (DOI 10.1016/j.jhsa.2006.01.009)- What it measures
- Eight elbows in eight patients with an average age of 62 were operated on. Pressure was measured with a fiberoptic transducer with the elbow extended and then flexed to 130 degrees.
- What it does not show
- Eight patients, all with established syndrome and all undergoing surgery. It cannot show the pressure in a healthy typist.
