Abstract
|
|
|
|
Isolated fracture of the distal humeral trochlea occurs while the axial load delivered to the elbow passes through the trochlear of the distal humerus. It has been rarely reported, because of those reasons. The trochlea is located deep inside of the elbow joint space and since it does not have the direct attachment with muscles or ligaments, a force is hardly transmitted directly. Also ulno-humeral joint is less influenced by compressive or shear force than radio-humeral joint. We report a case of isolated trochlear fracture with review of the literature.
