“…Colles' fracture) in women around the age of 45-60 years (Bauer, 1960) is indicative of a structural impairment of the trabecular framework of the distal radius and the distal ulna, obviously associated with the common involutional bone loss (Nordin, 1973). Whether Colles' fractures reflect generalized bone loss from the axial skeleton and thereby a condition of asymptomatic spinal osteopenia or pre-osteoporosis is largely unknown (Horsman, 1976). Previous Colles' fracture have been described with a frequency of about 20% in women with definite osteoporosis, i.e.…”

The aim of this investigation was to elucidate whether Colles' fractures in middle-aged women were indicative of generalized bone loss (osteopenia) and whether bone mass of the axial and the appendicular skeleton was related to the extent of daily physical activity. Thirty-six patients (aged 50-73 years) with previous Colles' fracture were studied. The median time elapse after the injury was 18 months (range 9-20.5 months). Bone mineral content of the 2nd, 3rd, and 4th lumbar vertebrae (lumbar BMC) and both distal forearms (forearm BMC) were determined to dual-photon (153Gd) absorptiometry. The physical activity level was graded according to a standard interview and a bicycle ergometer test. Mean lumbar BMC was reduced by 9% compared to age-matched normal women (p less than 0.05), mean forearm BMC was reduced by 5% (NS). Twenty patients showed spinal osteopenia by either conventional radiography or absorptiometry (95% confidence limits 38-72%). The fracture-related bone loss from the forearms was most prominent when the fracture had occurred in the dominant forearm, suggesting that the loss of 'dominant' forearm activity per se results in bone loss. No relation between working capacity and forearm BMC was found. However, the working capacity was positively related to lumbar BMC (P less than 0.01), even if the common relationship to age was eliminated (P less than 0.05). The data suggest that the bone mass of the axial skeleton reflects the extent of daily physical activity. Patients with Colles' fractures represent an easily definable population which might benefit from prophylactic measures against vertebral bone loss and compression fractures. One of these could be physical exercise.

“…Many different regions of the peripheral skeleton from the calcaneous [2 I] to the phalanges [22] have been investigated. Bone mineral mass within wider areas of the peripheral skeleton can be measured by rectilinear scanning [21] or alternatively by using a two-dimensional imaging detector and conical beam geometry [23][24][25], a method developed jointly by the MRC and the SERC Rutherford Laboratory.

Estimating total body calcium from peripheral bone measurements

et al. 1983

In a heterogeneous group of 12 male and 30 female patients, total body calcium (TBCa) was measured by neutron activation analysis, and bone mineral content of the distal femur and six regions of the distal radius and ulna were measured by photon absorptiometry. TBCa was an average of 71 g (9%) lower than normal in the females and 119 g (11%) lower than normal in the males. Of the forearm measurements, those of the radial shaft provided the best estimate of TBCa with a standard error of estimation (SEE) of 88 g (14% of the mean value) for female patients alone, and 113 g (16%) for the whole group. The measurement on the femur provided a better estimate with SEE 80 g (13%) for female patients and 90 g (13%) for the whole group. These SEE are comparable with the variability in TBCa between normal subjects, which has a coefficient of variation of the order of 20% in both sexes. A slightly better estimate of TBCa can be obtained by using a multiple regression equation involving both the femur and radial shaft measurements with a SEE of 74 g (12%) for female patients and 81 g (11%) for the whole group. The correlation between the estimated deficit of TBCa and the estimated deficit of bone mineral from the forearm and the femur has been calculated.
