Traumatic hip dislocation with spontaneous reduction and capsular interposition. A report of 2 children.

We present 2 cases of posterolateral hip dislocation in children followed by spontaneous reduction and interposition of soft tissue. After reduction of a dislocated hip joint, interposition of soft tissues or fracture fragments must be excluded. When reduction has occurred spontaneously, the condition may be misjudged, correct treatment delayed and the hip joint permanently damaged, as occurred in one of our cases. In the second case, prompt surgery was undertaken and the patient recovered completely.
