Description and evaluation of operative deformity correction in calcium-deficiency rickets in Kaduna, northern Nigeria.

Purpose: Rickets is a recurrent disease worldwide, especially in countries with limited resources (Nield et al Am Fam Physician 74(4):619-626, 2006; Thacher et al Ann Trop Paediatr 26(1):1-16, 2006). Medical therapy including orally administered calcium substitution is shown to improve a patients clinical symptoms and positively impact bone deformities, especially in the lower extremity. Even though orthopaedic intervention is necessary in a significant percentage of patients, few reports exist about operative deformity correction in patients wtih rickets.
