Blount's disease is a progressive form of genu varum due to asymmetrical 
inhibition of the postero medial portion of the proximal tibial epiphysis. The 
surgical treatments involved in correction of Blount's disease are often 
technically demanding, complicated procedures.  These procedures can lead to 
prolonged recovery times and poor patient compliance. In such a context we are 
suggesting "fibulectomy with Z osteotomy" of the proximal tibia, a relatively 
simple and highly effective technique. This technique is based on correcting the 
mechanical axis of the lower limb thereby restoring growth from the medial 
physis of proximal tibia. We have used a new surgical technique, which includes 
fibulectomy followed by a Z-shaped osteotomy. We have used this simple technique 
in a 5 year-old boy with unilateral Blount's disease. The femoro-tibial angle 
was corrected from 18.2° of varus to 4.2° of valgus. The angular correction 
obtained after operation was 22°. There were no postoperative complications. 
This technique has the advantages of correcting both angular and rotational 
deformities simultaneously.  The purpose of this case study is to introduce a 
new surgical technique in the treatment of Blount's disease.
