Recurrent voluntary anterior dislocation of the hip: case report and review of the literature.

Recurrent dislocation of the hip is uncommon in children, and anterior dislocation, as in the case reported, is extremely rare. Terminology is often confusing, with "recurrent," "voluntary," and "habitual" dislocations described. The causative pathology of the dislocation must be determined before appropriate treatment can be selected; computed tomography can be helpful in making this decision.
