Subluxation of the radius at the elbow in children results easily from a combination of pulling and twisting forces. In the seven cases here described the most frequent age was 3 years; the youngest and oldest patients were 10 months and 4 years of age. Three fell while at play, two fell while being held by the arm, one was lifted by the arm, and one had his arm twisted by a playmate. Reduction of the dislocation required but little force and sometimes occurred spontaneously or during examination. The technique for reduction here described involves supination of the forearm while the elbow is held in the extended position and slight pressure is applied to the head of the radius by the physician's thumb. The success of the maneuver is usually attended by a slight clicking sound and immediate relief of pain.
