Abstract

Background: Current innovation in needle arthroscopy is improving the safety of anterior portals around the elbow. This study evaluated the proximity to the radial nerve, median nerve, and brachial artery on cadaveric specimens of an anterior portal used for elbow arthroscopy. Methods: Ten fresh-frozen adult cadaveric extremities were used. After marking the cutaneous references, the NanoScope cannula was introduced just lateral to the biceps tendon, through the brachialis muscle and the anterior capsule. Elbow arthroscopy was performed. Dissection was then carefully performed on all specimens with the NanoScope cannula in place. The shortest distance from the cannula to the median nerve, radial nerve, and brachial artery was measured with a handheld sliding digital caliper. Results: The cannula was an average of 12.92 mm away from the radial nerve, 22.27 mm from the median nerve, and 16.8 mm from the brachial artery. Needle arthroscopy performed through this portal allows complete visualization of the anterior compartment of the elbow, as well as direct visualization of the posterolateral compartment. Conclusion: Needle arthroscopy of the elbow through an anterior transbrachialis portal is safe for the main neurovascular structures. In addition, this technique allows complete visualization of the anterior and posterolateral compartments of the elbow through the humerus-radius-ulna space.
