Developmental dysplasia of the hip (DDH) is a dynamic disorder and the malformations of anatomic structures are the result of gentle persistently applied forces in dislocating direction. When hips are placed in adduction and knees in full extension hip muscles (mainly adductors, iliopsoas, hamstrings) act in dislocating direction of the hip.

 Method

The concept of treatment consist of reversing the action of these muscle and to act gradually as relocating force by the use of splint and braces in two phases

Phase a (reduction) and Phase b( remodeling).
