Extraarticular fracture, wedge

General considerations

Metaphyseal wedge fractures are more often seen in younger patients and can result from higher energy injuries.

Careful inspection of radiographs should be undertaken to ensure that intraarticular extensions are not missed. Traction radiographs, oblique radiographs, or a CT scan may help to elucidate occult articular extensions. Surgeons should always be aware that it may not be until during surgery that an occult intraarticular extension is discovered and that they may need to deal with such a fracture by reducing the articular surface using a lag screw technique.
