Bone mineral content (BMC) in the distal end of the femoral shaft was monitored with single-photon gamma-absorptiometry for 72 weeks after surgery in 46 patients with coxarthrosis treated by total hip arthroplasty (THA). After an initial increase, which was greater in men than in women, BMC decreased during the first postoperative year to approximately the initial value in men, whereas in women the final outcome was a 10% net loss. No influence of the type of operation or of the preoperative or postoperative capacity of the patients could be demonstrated. The loss of bone mineral was surprisingly low compared with that noted after other injuries of similar or even less magnitude.
对46例行全髋关节置换术（THA）治疗的髋关节病患者，采用单光子γ吸收法监测术后72周股骨干远端的骨矿物质含量（BMC）。术后最初骨矿物质含量有所增加，男性增加幅度大于女性，术后第一年骨矿物质含量下降，男性降至约初始值，而女性最终净损失10%。未发现手术类型或患者术前及术后能力对其有影响。与其他程度相似甚至更小的损伤后相比，骨矿物质的损失出奇地低。
