Small long bones.

We have just had our anomaly scan on Friday. The organs and head and spine were fine. The femur and humarus are both measuring below 5th percentile. Both the femurs are both bowed and hands are at odd angles the feet are clubbed. The sonographer has made an appointment with a Fetal medicine consultant, the earliest is this Thursday. It isn't looking good. I am 20 weeks. Has anybody experienced anything similar?
