title: Recurrent dislocations of the hip in a child presenting as nocturnal pains.
abstract: Nocturnal pains of the leg were the only complaint of a 2 1/2-year-old girl with recurrent dislocations of the left hip. Unusual movement during sleep probably caused the dislocations. This case represents a benign entity characterized by spontaneous or voluntary posterior dislocations of the femoral head in young children without other significant connective tissue abnormalities.
