0.05), but radioactivity counting ratio of before and 2 years after operation wassignificantly lower than operation after 1-12 months (P 0.05). CONCLUSION: Automated ROI setting findings show that moderate load-bearing for patients with femoral neck fracture is favor to femur neck fracture healing and bone reconstruction.

Objective To study effects of multimodal analgesia on postoperative delirium (POD)in elder patients with hip fracture.Methods One hundred and eight elder patients with hip fractures were gathered in a prospective study.Fifty-nine cases were included in the group of multimodal analgesia (25 males,34 females),with an average age of 72.91±5.42 years,and 35 were treated with hip replacements,the other 24 were internal fixations.Forty-nine cases were in the group of conventional analgesia (22 males,27 females),with an average age of 72.14±4.93 years,29 were treated with hip replacements,20 were internal fixations.Assessments of delirium were based on confusion assessment method.Local infiltrated anesthesia,patient control intravenous analgesia,and intravenous nonsteroid anti-inflammatory drug were applied in the group of multimodal analgesia.For the other group,morphine would be given only when patient complained pain or there was POD.Postoperatively,visual analogue scale (VAS),onset of delirium,other correlative data were recorded by an independent researcher.All patients underwent POD were managed with intensive pain management,and then reevaluated.Results VAS in multimodal analgesia group [Day1:2.10±1.43(resting),4.74±1.45 (active) and Day 3:1.01±0.92 (resting),3.31±1.36 (active)] were significandy lower than that in the other group [Day1:4.67±1.33 (resting),7.44±1.59 (active)and Day 3:2.24±1.39 (resting),5.06±1.46 (active)].PODs were detected in 15 (30.6％) in group of conventional analgesia; while in group of multimodal analgesia,there were 7 (11.9％).All POD were given intensive pain managements by injection of 10 mg morphine and achieved relief of deliriums.Conclusion Postoperative multimodal analgesia may reduce the incidence of POD.First aid of intensive pain management may help to control POD.
