Three cases are presented: A congenital dislocation of the patella, a congenital dislocation of the radial head, and an epiphysiolysis of the distal humerus. In all three cases the pathology involved unossified parts of the skeleton poorly demonstrated by plain radiographs. Ultrasonography proved useful in diagnosis and treatment of these cases.
- Congenital dislocation of patella
