Case Report of Bilateral Lower Limb Deformity in Paediatric Age Group Secondary to Vitamin-D Resistant Rickets

A 4 years old male child brought to our outpatient department with chief complaint of bilateral lower limb deformity since the child started walking. After thorough clinical examination and investigations, the case was diagnosed as bilateral lower limb deformity secondary to vitamin-D resistant rickets. We managed the case surgically with bilateral epiphysiodesis initially. Later a period of 18 months to 2 years, osteotomy and fixation was done at multiple sites to correct the deformity further. Post operatively both lower limbs were immobilized in above knee pop cast in corrected position for 3 months. Regular follow up was advised. Vitamin-D and calcium supplementation was given throughout the treatment. At regular follow-up, patient obtained a physiological alignment and good bone formation is seen. Corrective osteotomy at different levels and plate fixation and immobilization in corrected position is a good option for the management of lower limb deformities secondary to vitamin-D resistant rickets in children.
