PURPOSE:
Pseudoepiphysis originates from the secondary ossification center of the non-ossification end during the normal pediatric growth process. It is not uncommonly found in the course of metacarpal and metatarsal ossification. We investigated the radiologic prevalence and features of pseudoepiphysis in normal Korean children. MATERIALS ANDMETHODS:
Sex and age distribution following radiologic prevalence as well as the features of metacarpal pseudoepiphysis of 2,320 Korean children aged below 15 years of age and younger who underwent hand radiography between January 2009 and February 2016 were analyzed.RESULTS:
A total of 304 out of 2,320 patients had pseudoepiphysis on metacarpal bone, which is a prevalence of 13.1%. Male showed higher prevalence (16.6% for male and 10.5% for female). The peak age was 11 years for boys and 5 years for girls. The first metacarpal bone was most prevalent, with 9.6% of the total population, followed by the second metacarpal bone (5.2%) and fifth metacarpal bone (2.5%). The prevalence of single pseudoepiphysis was 9.4%, and that of multiple pseudoepiphysis was 3.7%. The prevalence of incomplete pseudoepiphysis was 8.9% and was higher than complete pseudoepiphysis (5.6%).CONCLUSION:
The prevalence of metacarpal pseudoepiphysis in normal Korean children was 13.1%. It is necessary to be aware of the radiologic features and distributions of pseudoepiphysis to avoid misinterpretation as a bone disease or traumatic fracture in pediatric patients.
