Traumatic hip dislocation in children. Follow up of 13 cases.

Thirteen cases of traumatic anterior and posterior hip dislocations in children were treated during a period of 25 years. All of them were available for follow up from 5 to 26 years postinjury. Twelve of the patients had their dislocation reduced within six hours after the injury. None of them developed any complication, and the range of movement was the same as in the noninjured hip. One patient, who had his hip reduced 37 hours after the injury, experienced pain due to osteoarthritis 7 years after the injury at the age of 21 years.
