Cross-sectional study shows a strong correlation between skeletal age and chronological age in Pakistan, indicating potential for reliable assessments.
Objective: To determine the correlation of mean Bone age (BA), estimated with Greulich-Pyle(GP) method, with Chronological age (CA) in Pakistani individuals. Study Design: Cross-sectional study. Place and Duration of Study: Department of Diagnostic Radiology, KRL General Hospital, Islamabad, 06 months (April to September 2017). Methodology: A cross-sectional, observational study was done in Islamabad, comprising 250 individuals of both genders, selected through a non-probability consecutive sampling. Data were gathered on a prescribed proforma, and analysed by SPSS version 23. Results: Total of 250 individuals participated in this study. Skeletal age (SA) was estimated by observation of hand-wrist radiographs, using the GP atlas. Pearson correlation showed a significant correlation of SA & CA (r = 0.91; p-value < 0.0005). Stratification analysis was performed. Pearson correlation was found to be positive and highly significant for different CAs, gender and ethnicity groups. Conclusion: A positive correlation was found between GP atlas method in assessing SA and CA in the population of Pakistan. It can be used as quick, inexpensive and reliable method for SA estimation.
