Age estimation from iliac crest epiphyseal fusion by conventional radiographic techniques.

Abstract

Objective: To determine the correlation between radiological age estimation from iliac crest fusion and actual chronological age. Study Design: Cross sectional study. Setting: Forensic Medicine & Toxicology Department, King Edward Medical University, Lahore and Radiology Department, Mayo Hospital, Lahore. Period: 01-08-2023 to 31-01-2024. Methods: Data collection & analysis: Digital X-rays of the pelvis of 80 individuals showing iliac crest in antero-posterior view were taken. The radiographic age was estimated. Then actual age of patients was noted from national identity card, form B, birth certificate of the municipal committee or hospital, school certificate and driving license. Demographic data (name, gender, ethnicity, occupation) was also recorded. Data was entered and analyzed in SPSS. Results: There were 51(63.7%) males and 29(36.25%) females. The mean estimated age on X-ray was 20.10+2.19 years. The correlation coefficient (r) value of estimated age (years) on X-ray was 0.964 which indicates very strong positive correlation with actual age and was significant (p<0.0001). Males showed stronger positive correlation(r=0.976, p<0.0001) with estimated age (years) on x-ray as compared to females. Conclusion: It can be concluded from the study that mean age observed on X-ray was almost same as actual age, among all the individuals. There is strong correlation coefficient (r) of estimated age (years) on X-ray with actual age, and p value was significant.
