Blounts Disease MedPix

Description: Blount’s disease is a developmental deformity of the proximal tibial epiphysis that results in bowing of the lower extremities. It is divided into two forms: infantile and late-onset, which are determined based upon the age of onset and associated conditions. The deformity is thought to be a result of disturbed endochondral ossification secondary to abnormal pressure and force on the medial aspect of the proximal tibial epiphysis. Diagnosis is made by a combination of clinical presentation and plain film radiographic findings.
