Girl with Bilateral varus deformity

Saturday, April 24, 2010
This is the Xray showing both knee joints of  a 4 1/2 year old  female who was brought to the orthopedic clinic by her mother complaining of  a 1 1/2 year history of episodic left knee pain, worsening over the past 6 months, especially when walking.
On examiantion there was Bilateral varus deformity of lower extremities which was more prominent in the left side than the right side.

Identify this Xray ?


Blount's disease
Xray Findings
  • Bilateral depression and deformity of medial aspect of proximal tibial epiphysis and metaphysis
  • Beaking of proximal tibial metaphysis bilaterally

Differential Diagnosis:
1) Mild rickets
2) A physiological bow legs

Blount disease is a growth disorder of the tibia characterized by disordered ossification of the medial aspect of the proximal tibial physis, epiphysis, and metaphysis. This progressive deformity is manifested by varus angulation and internal rotation of the tibia in the proximal metaphyseal region immediately below the knee.

Blount disease most likely is caused by a combination of excessive compressive forces on the proximal medial metaphysis of the tibia and altered endochondral bone formation

Two main types
Infantile Blount disease - tends to be bilateral and occurs in children less than 3 years.The infantile form is generally more common in females and children generally start to walk early, usually when aged 9-10 months.
Juvenile Blount disease - usually unilateral seen in children aged 4-10 years

Xray Features
  • The medial epiphyseal line demonstrates irregularity
  • Abnormal sloping of the medial tibial epiphysis
  • The metaphyseal portion of the plate demonstrates irregular beaking

Treatment: Children can be treated by bracing, epiphyseal stapling, osteotomies, or in extreme cases, by intra-epiphyseal corrective realignment.
