Neurovascular impingement supracondylar fractures

Neurovascular relations. Right) If the spike of the proximal fracture fragment penetrates medially (posterolateral distal fracture fragment displacement), both the median nerve and brachial artery can be tethered. This type of neurovascular injury is most common. Left) If the proximal fracture fragment spike penetrates the brachialis muscle laterally (posteromedial distal fracture fragment displacement), the radial nerve may be tethered.
