The relationship between a decrease in systolic blood pressure following methylmethacrylate cement insertion in femoral head replacement and femoral canal diameter was investigated in 33 patients. A positive, significant correlation was demonstrated in all patients, especially among the female subgroup. Femoral canal diameters of 21 mm or more were associated with a significantly greater risk of intraoperative hypotension than were diameters of 20 mm or less. This relationship between femoral canal diameter and hypotension appears to be primary and unrelated to the patient's sex or age. In clinical terms, the femoral canal diameter may be easily measured prior to arthroplasty, and a diameter of 21 mm or more indicates an increased risk of hypotension following insertion of cement into the femoral canal.
在33例患者中研究了股骨头置换术中插入甲基丙烯酸甲酯骨水泥后收缩压降低与股骨髓腔直径之间的关系。在所有患者中均显示出显著的正相关，尤其是在女性亚组中。21mm或更大的股骨髓腔直径与术中低血压风险显著增加相关，而20mm或更小直径的风险则较低。股骨髓腔直径与低血压之间的这种关系似乎是原发性的，与患者的性别或年龄无关。从临床角度来看，在关节置换术前可以很容易地测量股骨髓腔直径，21mm或更大的直径表明在股骨髓腔内插入骨水泥后发生低血压的风险增加。
