Hi dr. Excuse me first for weak English writing. My child was diagnosed as a case of Calcaneal Valgus at birth day. We start treatment from birth day. Sonography analysis from hip didn’t show any abnormality. Physician treated her using casting method for three periods (each period 10 days). My child problem was fixed for 80%. But major worry is about limb length discrepancy because affected limb is evidently shorter than healthy limb. I am very worry. How can I fix this problem? Help me please
