Determination of the standard values of the hand bone mineral density values in males according to ages

Objective: In this study we purposed to determine standardvalues of hand Bone Mineral Density (BMD) accordingto ages by Dual Energy X-Ray Absorptiometry (DXA)in males who applied to our hospital, evaluate associationof hand BMD with lumbar and femur BMD and searchusefulness of hand BMD measurement by DXA.Methods: Totally, 239 male included, whose ages differbetween 27 to 87 years, had no disease associatedwith bone density were included. The cases, betweenthe ages 20 to 70 separated to age groups, comprisedof 5 years. Cases, whose age is 70 and older, included inthe same group. Average of dominant and nondominanthand BMD values of the chosen cases were computedaccording to age groups comprised of 5 years and theassociation with values of L2-L4 and femur neck BMD issearched separately.Results: There is significant association between dominanthand BMD scores with L2-L4 and femur neck BMDscores. Also there is significant association between nondominanthand BMD scores with L2-L4 and femur neckBMD scores. Also there is asignificant association betweenscores of hand BMD with hand grip strenght.Conclusion: In this study there is significant associationbetween BMD scores of dominant and nondominanthand with BMD scores of L2-L4 and femur neck in all agegroups. Rheumatological diseases, reflex sympatheticdystrophy, tendon and nerve lacerations of hand and forearm,fractures of upper extremity and hemiplegy, that cancauses local osteoporosis in the hand, measurement ofhand BMD can be done by DXA.Key words: Bone mineral density, dual energy X ray absorptiometry,osteoporosi
