"In 1963, the American orthopaedic surgeons Arthur Holstein (1914-2000) and Gwilym B Lewis (1914-2009) described this pattern of fracture with an increased risk of radial nerve palsy 5."
"The spiral fracture line is usually evident. The fracture is located in the distal to the middle third of the humeral shaft. There is radial (lateral) displacement of the distal fragment 1,3,4."
