Tibial/femoral hypoplasia with "hook" pelvis: a potentially unique dysostosis

We report a 2-year-5-month-old girl with malformed lower limbs. The radiographic skeletal survey revealed agenesis of the ilio-pubic rami with pubic dehiscence, right hip dislocation, bilateral coxa vara, short femurs, femoro-tibial synchondrosis, bilateral hypoplastic tibiae more severe on the left side, and hypoplastic left calcaneus and talus. To the best of our knowledge, this combination of multiple congenital skeletal abnormalities has not been reported before.
