Aitken classification
A grading system for proximal focal femoral deficiency based on the presence and development of the femoral head and acetabulum.
Full Definition
The Aitken classification is a widely used system for categorizing the severity of proximal focal femoral deficiency (PFFD). Developed by Dr. George Aitken, the system divides PFFD into four classes (A through D) based on radiographic findings of the femoral head, neck, and acetabulum. Class A represents the mildest form with a present femoral head, while Class D represents the most severe form with complete absence of the femoral head and acetabulum. This classification system helps guide treatment decisions and prognosis, with higher grades typically requiring more extensive interventions such as prosthetic fitting rather than reconstructive surgery.
Usage
Usage note: Should be capitalized as it is named after Dr. Aitken.
