摘要:

背景:无论是股骨侧还是髋臼侧在髋关节置换后1年内均会出现不同程度的骨丢失,对假体的长期稳定性和骨强度造成严重影响。因而减少全髋关节置换后假体柄周围骨丢失量对延长假体使用时间、预防假体周围骨折具有重要意义。
目的:观察分析唑来膦酸对髋关节置换后假体柄周围骨丢失的预防效果。
方法:对照组患者不给予,两组其余用药相同。对两组置换前和置换后1年的髋部骨密度变化进行测量;观察两组置换前、用药后3 d和用药后1年的血清钙、磷水平及碱性磷酸酶活性变化;对观察组患者用药期间出现的不良反应进行记录。 
结果与结论:置换后1年两组患者股骨假体周围的平均骨密度均显著下降,与置换前比较差异有显著性意义(P < 0.05)。置换后1年观察组患者的平均骨密度显著高于对照组(P < 0.05)。用药后3 d两组患者的钙、磷水平均较置换前显著下降,差异均有显著性意义(P < 0.05)。用药后1年钙、磷水平维持在置换前水平。置换后短期内两组患者的碱性磷酸酶活性均稍微下降,但与置换前比较差异无显著性意义(P > 0.05)。用药后1年,观察组患者的碱性磷酸酶活性较低,与置换前、对照组比较差异均有显著性意义(P < 0.05)。用药后1年,对照组患者的碱性磷酸酶活性与置换前差异无显著性意义(P > 0.05)。用药两三天内观察组有9例患者出现不同程度的肌肉酸痛和发热,给予乙酰氨基酚后症状得到缓解。提示全髋关节置换后给予唑来膦酸注射液能够有效预防患者置换后早期假体柄周围骨丢失,但是置换后1周内可能会出现发热的症状,因此建议在置换完成1周后给予患者唑来膦酸注射液,若出现发热等症状,可给予乙酰氨基酚进行缓解。

Abstract:

BACKGROUND: Bone loss to different degrees may appear within 1 year after hip replacement in the femoral or acetabular sides, and severely affect long-term stability of the prosthesis and bone strength. Thus, to reduce bone loss around the prosthesis stem after total hip replacement is significant to prolong the use time of the prosthesis and to prevent fractures surrounding the prosthesis.
OBJECTIVE: To observe the preventive effect of zoledronic acid on bone loss surrounding the prosthesis stem after hip replacement.  
METHODS: A total of 80 patients after total hip replacement in the People’s Hospital of Shenxian from February 2011 to September 2014 were enrolled in this study. They were divided into two groups (n=40). At 4 days after replacement, patients in the observation group received treatment with zoledronic acid, but those in the control 
group did not give zoledronic acid. The rest medication was identical between the two groups. Bone mineral density in the hip was measured before replacement and at 1 year after replacement in both groups. Serum calcium and phosphorus levels and alkaline phosphatase activities were observed before replacement, 3 days and 1 year after medication in the two groups. Adverse reaction during medication was recorded in the observation group.
RESULTS AND CONCLUSION: The average bone mineral density was significantly decreased in both groups at 1 year after replacement, and significant differences were found as compared with before replacement (P < 0.05). The average bone mineral density was significantly higher in the observation group than in the control group at 1 year after replacement (P < 0.05). Calcium and phosphorus levels were significantly diminished at 3 days after medication as compared with that before replacement (P < 0.05). Calcium and phosphorus levels maintained at the level before replacement at 1 year after medication. Alkaline phosphatase activities were slightly reduced within a short time after replacement in both groups, but no significant difference was found as compared with before replacement (P > 0.05). Alkaline phosphatase activities were low in the observation group at 1 year after medication, and significant difference was detected as compared with the control group and that before replacement (P < 0.05). No significant difference in alkaline phosphatase activities was detectable in the control group between 1-year post medication and pre-replacement (P > 0.05). Within two or three days after medication, nine patients suffered from varying degrees of muscle aches and fever in the observation group, and above symptoms were lessened after taking acetaminophen. These results verify that after total hip replacement, zoledronic acid injection can effectively prevent bone loss around the prosthesis in early stage after replacement, but fever symptoms may occur within a week after replacement. Thus, it is recommended that zoledronic acid injection can be given at 1 week after replacement. If fever and other symptoms appear, acetaminophen can be given.
