Hamanishi developed a scoring system for evaluating a patient with a congenital short femur. This can help determine the severity of congenital anomalies affecting the patient. The author is from Kyoto University.
Parameters:
(1) short femur
(2) tibia
(3) fibula
(4) upper limb

where:
• Severe anomalies are scored 3 while moderate anomalies are scored 2.
• Scoring bilateral disease is a little unclear. Bilaterality is specified for tibia and upper limb, but it is not specified for the femur or fibula.
• Bilateral moderate anomalies are considered a severe deformity. It is unclear if bilateral mild anomalies constitutes a moderate deformity, or if a severe anomaly on the opposite side overrides a minor anomaly on the same side as the short femur.
