Type II and III pediatric supracondylar fractures are often treated with closed reduction and fixation with pins or wires. (Type I fractures are splinted, then casted).

In this case Steinmann pins were used for fixation. Some surgeon use a lateral pin technique (as above) and some use a crossed-pin approach.

Early complications include vascular compromise and peripheral nerve injury (e.g. ulnar nerve injury if a median pin approach is performed).

Late complications include malunion, particularly a malunion with a varus/valgus orientation. Pins occasionally can back out or become infected.
