Obturator dislocation as a complication of closed reduction of the congenitally dislocated hip: a report of two cases.

Two cases of inferior obturator dislocation complicating treatment of congenital hip dislocation with closed reduction are described. Abduction and hyperflexion appear to be predisposing factors in development of this complication. Application of skin traction before any attempt is made at reduction will lengthen contracted soft tissues and may convert the inferior dislocation to a more manageable position. Open reduction was necessary in both patients, and the results were considered good.
