Proximal radial fractures can occur in the radial head or the radial neck. This is a well recognised complication of a dislocated elbow, occurring in 50% of cases following an elbow subluxation or dislocation. But: there were no instances in which the trochlear ossification centre appeared before the medial (internal) epicondylar centre. Positive fat pad sign (2)Any elbow joint distention either hemorrhagic, inflammatory or traumatic gives rise to a positive fat pad sign. Approximately 2-3% of all ED visits involve the elbow. Be careful: in very young children the ossification within the cartilage of the capitellum might be minimal (ie normal and age related), and so is insufficiently calcified and does not allow application of the above rule.

Though the CRITOL sequence may vary slightly there is a constant: the trochlear (T) centre always ossifies after the internal epicondyle. Rotation will project the metaphysis of the humerus away from a normally positioned epicondyle. So, if you see the ossified T before the I then the internal epicondyle has almost certainly been avulsed and is lying within the joint ie it is masquerading as the trochlear ossification centre (see p. 105).
