| Abstrakt: | Purpose: The purpose of this study is to describe the placement and evaluate the safety of the far anterior proximal and distal anteromedial portals by comparing them to previously defined portal techniques in a cadaveric model of the elbow. Methods: Six paired (left and right) fresh, frozen cadaveric elbow joints were dissected. .62-mm Kirschner wires were placed at the literature-defined distal and proximal portal sites on right elbows. The proposed "far anterior" distal and proximal portals were established on the matched left elbows. The elbows were dissected to display the median and ulnar nerves. Digital calipers were used to measure distances from wires to nerves. Results: For the distal portal, the literature-defined portals were a significantly greater distance ( P = .014) from the ulnar nerve (31.22 mm) compared to the far anterior portals (24.65 mm). For the proximal portal, the far anterior portals were a significantly greater distance ( P = .026) from the ulnar nerve (26.98 mm) than the literature-defined portals (13.75 mm). There was no significant difference between the far anterior and literature-defined proximal and distal portal techniques in relation to the median nerve. Conclusions: Analysis of elbow arthroscopy anteromedial portal technique shows the far, anterior, proximal, and distal portals are a safe distance from the ulnar and median nerves. A portal modification that may address complicated elbow conditions is a more anterior placement of the medial portals to allow for better visualization and access. Clinical Relevance: The elbow is a difficult joint in which to perform arthroscopic surgery. One option our institution has used for safe portal modification to address complicated elbow conditions is a further anterior placement of the medial portals to allow better visualization and access.
