一种非创伤性可靠的评价骨强度方法,能够对决定何时开始负重有帮助,并能早期发现延迟愈合和骨不连。X线片、CT、骨闪烁成象和超声对骨折愈合强度的评价并不尽人意。以双能X线吸收计(DEXA)测定骨矿物质密度和骨矿物质含量,是目前载体测量骨密度和骨质量最为准确的方法。试验中DEXA被用来评估闭合胫骨骨折的愈合强度。人为造成40只山羊左侧胫骨中段简单横型和简单斜形骨折,并以双边AO外固支架
A noninvasive and reliable method of evaluating bone strength can be helpful in deciding when to start weight loss and early detection of delayed union and nonunion. X ray, CT, bone scintigraphy and ultrasound evaluation of fracture healing strength is not satisfactory. Determination of bone mineral density and bone mineral content with a dual energy X-ray absorptiometer (DEXA) is the most accurate method for vector measurement of bone mineral density and bone mass. DEXA was used in trials to assess the healing strength of closed tibial fractures.
