An approach to the posterior interosseous nerve.

An exposure of the posterior interosseous nerve has been described. We feel this exposure is simple, anatomic, and atraumatic and yet provides excellent visualization of the posterior interosseous nerve. In addition, proximal and distal exposure of the nerve is easily obtained. This exposure has been used in various clinical settings from trauma to compressive lesions. It has proved both effective and superior to any previously described exposures of the posterior interosseous nerve.
