ObjectiveThe purposes of this study were to measure the average distance from a percutaneous pin in each quadrant of the distal fibula to the sural nerve and nearest peroneal tendon, and define the safe zone for percutaneous pin placement as would be used during surgery.MethodTen fresh-frozen cadavers underwent percutaneous pin fixation into four quadrants of the distal fibula. The sural nerve and peroneal tendon were identified as they coursed around the lateral ankle. Distances from the K-wire in each quadrant to the anatomic structure of interest were measured.ResultsAverage distances (mm) from the K-wire to the sural nerve in the anterolateral, anteromedial, posterolateral, and posteromedial quadrants were 19.1±8.9 (range, 5.1-35.5), 12.8±8.2 (range, 0.3-27.8), 12.6±6.8 (range, 3.0-27.8), and 5.9±5.5 (range, 0.1-19.9), respectively. Average distances from the K-wire to the nearest peroneal tendon in the anterolateral, anteromedial, posterolateral, and posteromedial quadrants were 15.7±4.4 (range, 9.5-23.1), 11.9±5.2 (range, 3.2-21.7), 6.3±3.9 (range, 0.1-14.4), and 1.0±1.6 (range, 0-5.6), respectively.ConclusionsPercutaneous pinning of distal fibula fractures is a successful treatment option with minimal complications. Our anatomical study found the safe zone of percutaneous pin placement to be in the anterolateral quadrant. The sural nerve can be as close as 5.1mm and the peroneal tendons as near as 15.7mm. In contrast, the posteromedial quadrant was associated with the greatest risk of injury to both the sural nerve and peroneal tendons.Copyright © 2014 Elsevier Ltd. All rights reserved.
