Femur fibula ulna syndrome
Femur-fibula-ulna syndrome is a very rare syndrome characterized by abnormalities of the femur, fibula and the ulna. There have been suggestions that FFU complex may be the same as proximal femoral focal deficiency although authors are currently in disagreement over whether or not the disorders are in fact separate. The breadth of the abnormality and number of limbs involved is considered sporadic although upper limbs are more affected than lower limbs and right side malformation is more prevalent than the left. The condition was first noted by Lenz and Feldman in 1977.
