A cadaveric study of endoscopic decompression of the cubital tunnel.

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