Abstract

Measurement of the cortical thickness of the tubular bone has recently been known as a one of the best methoddiagnosing osteoporosis. It is suggested that the combined cortical thickness of better than other morecomplicated indices. The authers have attempted to measure the combined cortical thickness of the lower shaft ofhumerus and mid-shaft of the metacarpal, and review of literatures were carried out. The resuls are as follows; 1.The mean value of combined cortical thickness (CCT) of metacarpus and humerus of various age groups has beenmeasured and calculated on roentgenograms in 791 patients. In the male, CCT of 2nd metacarpus is 4.7±0.15mm, 3rdmetacarpus is 4.3±0.11mm, 4th metacarpus is 4.1±0.20 mm. on 30-39 age group, and CCT of humerus is 9.4±0.28mm.In the female, CCT of 2nd metacarpus is 4.6±0.17mm, 3rd meacarpus is 4.3±0.12, 4th metacarpus is 4.2±0.41 mm.on 40-49 age group, CCT of humerus is 8.6±0.13 mm. on 30-39 age group. 2. Measurement of combined corticalthickness in the humerus demonstrated a gradual decrease of the cortext after 40-49 age groups in both sexed,while in the cases of metacarpus, measurement of CCT in the 2nd metacarpus only demonstrated a gradual decrease ofcortex with age in female. 3. Reduction rate of CCT is 1.5±0.31mm./10 yrs between 50-59 age group and 60-69 agegroup in the humerus, in male. Mean reduction rate of CCT is 0.6±0.21mm./10 yrs after 30-39 age group in thefemale.
