title: Operative treatment of bilateral hip dislocations in a child with metatropic dysplasia.
abstract: We present a case of bilateral hip dislocations with metatropic dysplasia. Radiographic features such as narrow thorax, dense wafer vertebral bodies, narrowing interpedicular distances, kyphoscoliosis, crescent-shaped iliac wings, dumbbell-shaped tubular bones, and inferiorly directing lesser trochanter conform to the findings of metatropic dysplasia. Hip dislocations were misdiagnosed by ultrasonographic and radiographic hip screening, owing to the severely deformed femoral heads and acetabulums. The diagnosis of hip dislocations became possible by magnetic resonance imaging. The bilateral hip dislocation was reduced by open reduction of the hip joints and femoral derotation varus osteotomies.
