[Posttraumatic complications on children's elbows].

Most fractures during growth affect the upper extremities. Severe fractures with an increased number of complications are mainly localized beyond the elbow joint. Displaced fractures of the elbow joint have limited potential for spontaneous correction as the bones near the elbow joint account for only 20% of growth in length and the possibility of spontaneous correction is already exhausted at the age of 7. The consequences of inadequately reduced elbow fractures, therefore, may adversely affect a patient for his lifetime. Cubitus varus and valgus are the most common deformities following insufficiently treated supracondylar humerus fractures, fractures of the radial or dislocations of the radial head. Posttraumatic deformities of the elbow are usually the result of an insufficient primary therapy and rarely the result of growth disturbances. For the attending surgeon, posttraumatic deformities on a child's elbow are challenging.
