Hip joint arthroplasty in pubic symphysis separation in the course of congenital bladder exstrophy - study of two cases.

Congenital bladder exstrophy is a severe congenital malformation identified in one out of 30,000-50,000 live newborns and seen more often in girls. Some patients develop osteoarthritis of the hip joints which requires total hip arthroplasty. Reports of such cases are very rare in the world literature, which prompted us to present two cases treated at our Department and analyse their early outcomes. Our experience so far has been rather modest but the results encourage considering total hip arthroplasty in the treatment of hip osteoarthritis in future patients with pubic symphysis separation in the course of congenital bladder exstrophy.
