## Overview Fractures caused by direct trauma or hyperextension occur when a bone is struck or forced beyond its normal range. Common examples include carpal chip fractures from hyperextension in racehorses and traumatic fractures from kicks or falls. Treatment depends on location and articular involvement. ## Causes Acute overload or impact. ## Diagnosis Radiographs. Arthroscopy for articular fragments. ## Treatment Arthroscopic removal for many chips; internal fixation for larger or unstable fractures. ## Recovery and Prognosis Good for many articular chips. Larger traumatic fractures have a more variable outlook. ## Prevention Conditioning and safe environments.
