Tags: Accident and Emergency Radiology A Survival Guide // If there's another sharing window open, close it. Displaced epicondyle fractures can be missed if the normal pattern of ossification development is not recognized.7. Check for errors and try again. The growth plates are vulnerable to traction or shearing forces which result in fracture and/or apophyseal injuries. The Trochlea has two or more ossification centres which can give the trochlea a fragmented appearance. Rotation will project the metaphysis of the humerus away from a normally positioned epicondyle. The medial epicondyle is an apophysis since it does not contribute to the longitudinal growth of the humerus. Lateral viewchild age 9 or 10 years AP and lateral: the CRITOL sequence Most of these fractures consist of greenstick or torus fractures.
