Aims and objectives
Proximal femoral focal deficiency is a rare congenital limb anomalywith failure development of proximal part of femur.Most scientific articles pointed that proximal part of femur partially or completely absent .
The purpose of our study was to evaluate the different types of proximal femoral focal deficiency (PFFD) in children with MRI and CT.
Methods and materials
We exam 11 children with congenital severe shortening anomaly of low leg.
The age of our patients was 13 mo.
to 9 year; 5 male,
MRI of pelvis and low legs was performed in 8 children.
MDCT of pelvis,
hip and femur was performed in 5 children.
We classified PFFD by Amstutz classification system (Fig.
All CT and MRI exams were evaluated independently by two experienced radiologist. We analyzed ossified and cartilaginous components of proximal femur and acetabulum,
In our pediatric patients with proximal femoral focal deficiencyAmstutz type 1 was in one child with bilateral changes (9%); Amstutz type 2 - 3 patients (27%); Amstutz type 3 - 3 patients (27%); Amstutz type 4 - 3 children (27%).
Also we find Amstutz type 5 in one 27 mo old girl with bilateral PFFD (9%).
In type 1 to 3 we find classic appearances of dysplastic femoral head and neck.
Great trochanters was seen as usual with normal size and higher position due to varus deformity (Fig.
In our data we find that with severe types of proximal femoral focal deficiency patients still have hypertrophied cartilaginous great trochanter as a part of proximal femur.
We think that our report can be important for further investigations and adequate operative reconstructive planning.
