Blount-disease refers to a deforming osteochondrosis of the medial aspect of the proximal tibia,
which includes infantile,
juvenile and late onset types,
based on the age and the clinical onset of the disease.
Conventional radiography is a fundamental tool in the diagnosis,
staging and surgical planning of Blount-disease.
Radiologists should be familiar with the Langenskiöld-stages,
the normal values and age-dependent changes of the meta-diaphyseal and tibiofemoral angle.
at an early age,
differentiating Blount-disease from physisologic bowing is not easy.
Observation and follow-up images might unravel the differential diagnostic problem.
MRI should be integrated in the diagnostic algorhythm before surgery for better visualization of additional abnormalities of the knee,
and the state of the physis.
With careful consideration for each patient’s unique circumstance, treatment through corrective bracing,
growth plate manipulation,
or tibial osteotomy can effectively repair the deformity.
Blount-disease left untreated,
can lead to multiplanar deformity and degenerative arthritis,
so it is essential that all imaging modalities are employed and all efforts are made to recognize and educate about this disease.
