Abstract:
Objective To study age-related structural changes of proximal humerusin Chinese Han adults,for the application inage estimation.Methods Shoulder joint computed radiographs(CR) of 210 Chinese Han adults were sampled,with 124 males aging from 18 to 83 years old and 86 females aging 18 to 60 years old.Four observation indexes (the height of humerus bone marrow cavity,the change of trabecular bone in proximal humeral epiphysis,the change of trabecular bone in humeral macronodular and the change of trabecular bone in subacromial-clavicular bone marrow cavity) related with age were observed and scored.The regression equations of age estimation and change scores were established and tested statistically.Results Every index wasclosely correlated with the age changes inadults.The changes of trabecular bone in proximal humeral epiphysis and the changes of trabecular bone in subacromialclavicular bone marrow cavity have much better effects than the height of humerus bone marrow cavity and the changes of trabecular bone in humeral macronodular.The regression equations could predict the age of Chinese Han adults with satisfactory accuracy.Conclusion CR changes of the height of humerus bone marrow cavity,the changes of trabecular bone in proximal humeral epiphysis,the changes of trabecular bone in humeral macronodular and the changes of trabecular bone in subacromial-clavieular bone marrow cavity can bepracticallyusefulin age estimation for Chinese Han adults.
