Deformation of the thigh bone

What exactly is PFFD?

PFFD (proximal femoral focal deficiency) refers to a congenital deformity of the femur. This rare disease includes a wide range of defects in the thigh area. The hip joint is generally affected as well.

The cause of PFFD is still unknown. However, it is clear that there are no underlying genetic factors. In milder forms, the femur (thigh bone) is only slightly underdeveloped; in more severe forms, the thigh is almost completely missing. In around 15% of cases, both legs are affected.

The shortening of the thigh in PFFD depends on the severity of the disease. In around 60–80% of cases,  congenital fibular hemimelia is also present. Additional deformities of the lower leg and foot are also possible. Children with PFFD typically have good physical and mental health.

Malformations on all four extremities

They had not expected it and were completely unprepared for this outcome: Until his birth, Nathanael’s parents thought that they would deliver a healthy child. When their first-born son was born, they were shocked: Nathanael has dysmelia affecting all four limbs.
