Background:
Divergent pediatric elbow dislocations are very rare injuries.
Case:
An eight-year-old boy presented to the emergency department with elbow pain after a fall. On examination his elbow was swollen; skin and neurovascular function were intact. Radiographs demonstrated a divergent elbow dislocation. After successful closed reduction under sedation, the arm was casted; gentle motion was initiated at three weeks. At four months, the patient had full strength, no symptoms, and nearly full range of motion.
Interpretation:
The literature on the treatment of this injury is limited because of its rarity. We present a case of successful nonoperative management. The return of this patient for compressive symptoms should serve as a reminder that these injuries may be at high risk for compartment syndrome, possibly due to the high level of soft tissue disruption.
