Bone age in children with obstetrical brachial plexus palsy: effect of peripheral nerve injury on skeletal maturation.
The purpose of this retrospective study was to analyze the effect of peripheral nerve injury on the skeletal maturation process. The bone ages of the affected and unaffected hand-wrists of 42 children with obstetrical brachial palsy were determined according to the Greulich and Pyle atlas. In 23 patients, the bone ages of the both sides were identical (bone-age-symmetrical group), in 19 patients the bone age of the affected side was delayed (bone-age-delayed group). The mean bone age of the affected side was delayed 0.48 ± 0.25 years that of the unaffected side (P = .000), and the delay of bone age was inversely correlated with chronological age (R (2) = .45, P < .02) in the bone-age-delayed group. Skeletal retardation can be recognized after appearance of ossification centers by plain radiography, dating from the third month of life, in early infancy. Thus, bone age determination method might be helpful for predicting potential future limb shortness.
