Posterior instability of the hip in an adult : A case report

Dislocation of the hip except as a congenital or developmental lesion is not common, and the onset of symptoms because of posterior instability of the hip in an adult has not been reported previously. An adult patient who had benign congenital hypotonia as an infant and who presented with generalized ligamentous laxity and hip pain associated with recurring posterior subluxation of the hip is the subject of this report.
