VARIATIONS IN THE AGE OF FUSION OF ISCHIAL TUBEROSITY; A RADIOLOGICAL STUDY

Hina Siddiqi, Sarah Nisar, Nazish Waheed

Abstract


Background: Human skeleton develops from separate ossification centres which continue to
ossify till the bone is completely formed. Radiological techniques are very reliable and useful
method for estimating the age of individual for forensic and criminal reasons by observing these
ossification centres. External inspection for age determination is liable to error. This study is thus
aimed to assess the variation in age of fusion of ischial tuberosity in Pakistani population.
Methods: It was a cross sectional study, wherein data was retrospectively collected at Bahawalpur
Victoria Hospital, a tertiary referral centre in which consecutively selected 47 females and 121
males between 10 to 24 years of age, attending the outpatient, referred from National Database
and Registration Authority for the confirmation of age were selected. Results: There were a total
of 13 cases in stage I, 98 in stage II, 23 in stage III and 34 in stage IV. In stage II maximum
numbers of cases were between the ages of 19–22 years whereas in stage IV the maximum
numbers of cases were between 21–24 years of age. Conclusion: It is concluded that the earliest
appearance of epiphyseal center in males occurred at 12-13 years and in females at 10-11 years.
While earliest complete union was seen at the age of 19–20 years in females and 16–17 years in
males. All cases in age group of 23–24 years showed complete union.
