The aim of this study was to compare the linear growth of children with cerebral palsy (CP) with that of children without CP. The segmental lengths (humerus, ulna, femur, tibia, and spine), recumbent length, body weight, and bone age of 62 children with CP (age range 2.25 to 14 years, mean 7.13 years) were measured and compared with 68 children without CP (age range 1.50 to 12.67 years, mean 6.73 years). The results show that bone-age delay is common in children with CP (68% with a delay of more than 1 year). The linear growth of children with CP is similar to that of children without CP when bone age is used instead of chronological age. There is a strong correlation between segmental lengths and body height. Hence, this study favours using segmental lengths for estimating height in children with CP and using the comparison group as a reference for this purpose. Nutritional and non-nutritional factors on bone-age delay are discussed.
