The bone mineral content across the calcaneus was measured by gamma absorptiometry in 82 patients with operated on ankle fractures. A mean deviation in bone mineral content between the injured and the uninjured leg of 6 percent was found. Early weight bearing in a walking cast or brace did not influence the process of postfractural osteopenia. Compared with the patients with isolated lateral malleolar fractures, the patients with bimalleolar and trimalleolar fractures were older and had a lower bone mineral content in the calcaneus of their uninjured leg. The percentage of deviation in bone mineral content between the injured and uninjured leg was also greater in patients with more severe fractures.
采用γ吸收法对82例接受踝关节骨折手术的患者跟骨的骨矿物质含量进行了测量。结果发现，患侧与未患侧腿的骨矿物质含量平均偏差为6%。采用行走石膏或支具进行早期负重对骨折后骨质减少的过程没有影响。与单纯外踝骨折患者相比，双踝和三踝骨折患者年龄更大，其未患侧腿跟骨的骨矿物质含量更低。骨折越严重的患者，患侧与未患侧腿骨矿物质含量的偏差百分比也越大。
