Bone mineral density in patient admitted to Hospital Raja Perempuan Zainab II with proximal femur fracture.
Masters thesis, Universiti Sains Malaysia.
Abstract
ABSTRACT
Osteoporosis has been recognized as an established and well-defined disease
that affects more than 8.9 million fractures annually worldwide. Most studies of
fracture involving the proximal femur claim that generalized osteoporosis is the
major etiological factor, although none has established a densitometric fracture
threshold above which such fractures would not occur.
Objectives
This is a cross sectional analytical study with aims to identify the bone
mineral density of elderly patients admitted for fracture proximal femur in an
institution as assessed by Dual Energy X-Ray Absoptiometry (DXA) scan as well as
to determine the biodemographics of the said profiles.
Methodology
Bone mineral density of 15 patients admitted for proximal femur fractures
were evaluated using DXA scan.The T-score was further evaluated to see the
significance of osteoporosis in these sujects.Results
The mean age of the subject was 70 years old, and 80% were malays. 60% of
them were non-milk consumer, and 80% were categorized under low socioeconomic
group. Only 33% were a smoker. Bone density of neck of hip among the patients had
the lowest median with -1.70 and interquartile range of 1.10. Then, it was followed
by bone density for total hip and spine with median value of -1.60 and -1.40
respectively. Majority of the patients who involved in this study had their bonemineral density value as osteopenia. The highest osteopenia percentage was for the
neck of hip, 66.7 %. Then it was followed by total hip and spine, 60% and 33.3 %
respectively. The percentage of patients with osteoporotic group of BMD for total
hip, spine and neck of hip were 6.7%, 33.3% and 20% respectively. 5 (33.3%)
patients had their BMD total hip as normal, 5 (33.3%) patients for spine and 2 (20%)
patient for neck of hip. Out of 15 subjects, only 1 who had all three BMD value of
total hip, spine and neck of hip as osteoporosis. Fisher’s Exact test analysis found
that there were no significant association between studied bio-demographic and bone
mineral density at all measured sites.
Conclusion
This study found that there were no significant association between studied
bio-demographic and bone mineral density at all measured sites. Majority of the
patients who involved in this study had their bone mineral density value as
osteopenia. The highest osteopenia percentage was for the neck of hip, 66.7 %,
followed by total hip and spine, 60 and 33.3 % respectively.
