Study of Ossification Centres Around the Elbow and Wrist of Adolescent Age Group 15-18 Years
Keywords:Age, X-rays, ossification, fusion.
Intoduction: Determination of age in both living and dead plays a pivotal role in medicolegal cases.
There are various parameters to assess the age by physical characteristics, odontological development
but the most valuable method seems to be the osteological changes observed by radiological examination
ie., the appearance and fusion of secondary ossification centres around respective joints The present
study was conducted on 131 subjects out of which 110 were males and 21 were females. The main aim
of the study was to find the age of fusion of secondary ossification centres around elbow and wrist joint,
to compare the distribution of fusion of ossification centres between males and females
Methods: Firstly informed consent was taken. Preliminary details of each individual was noted that
included general examination, physical examination, dental examination followed by taking X-ray AP
view of elbow and wrist joint for radiological examination. The results were noted based on the degree
of fusion as No Union (O), Beginning union(B), Recent union(R), Complete union(C).
Results: The present study showed among males, the fusion for each ossification centre around elbow
joint started by 15-16 years and was completed by 18-19 years whereas in females it started fusion by
15-16 years but complete fusion occurred around 16-17 years itself . In wrist joint the fusion starts at
16-17 years in males but only fusion of lower end of ulna is completed by 18-19 years, however both
lower end of radius and ulna are fused by 18-19 years in females.
Conclusion: Based on the analysis of fusion of ossification centres it shows that both thecentres around
elbow and wrist joint fuses earlier in females by 1-2 years than males.
