Origami in dynamic hip screw surgery

Injury. 2004 Oct;35(10):1039-41. doi: 10.1016/j.injury.2003.12.010.


The insertion of a dynamic hip screw requires assessment of the native angle of the femoral neck. The two commonly used angles of DHS insertion are 135 and 150 degrees. We present a simple way of judging whether a 135 or 150 degrees angle plate is more suitable in the preoperative plan by using one or two sheets of A4 or letter paper, respectively.
