A cadaveric study of endoscopic decompression of the cubital tunnel was per
formed. Four fresh-frozen upper limbs were used for dissection, with a focu
s on the relationship between the ulnar nerve and Osborne's band. The endos
copic procedure was performed with the Ectra II system (Smith & Nephew, And
over, MA). After the surgical procedure, further dissection was done to eva
luate the effectiveness and safety of the endoscopic cut of Osborne's hand.
Our conclusion is that endoscopic release is not a technically difficult p
rocedure, and may be limited to certain clinical situations.
