Abstract
1. A collected series of forty-seven traumatic dislocations of the hip in children is reported and reviewed in detail.
2. All were simple hip dislocations, and no child was included in whom there was any other injury to the affected joint.
3. All were posterior dislocations.
4. No anatomical predisposition was observed.
5. Significant complications occurred in fourteen children: avascular necrosis of the head of the femur in four, degenerative joint changes in three, premature epiphysial fusion in one and overgrowth of the femoral head in six. Study of the children with these complications revealed no common cause except the dislocation itself.
6. The injury responsible was often trivial.
7. The results suggest that it is harmless to bear weight four weeks after reduction.
