摘　　要：目的：对比OCM入路微创小切口全髋关节置换术（THA）和常规外侧入路手术下隐性失血量，并探讨原因。方法选择2014年4月～2015年1月人工关节置换术患者50例，年龄29～93岁，其中行单侧OCM入路微创小切口THA患者22例，余行常规外侧入路。根据GROSS方程计算总失血量、隐性失血量及隐性失血率。比较两种入路隐形失血量。结果常规外侧入路组实际总失血量为（1584.4±592.6） ml，隐性失血量为（981.7±345.3）ml，隐性失血率均值为62%。OCM入路组实际总失血量为（1408.4±518.1）ml，隐性失血量为（788.4±245.4） ml，隐性失血率均值为56%。两组在术中出血量方面比较，OCM入路组的隐性失血量较常规外侧入路组减少（P〉0.05）。结论采用OCM微创小切口手术入路THA可降低隐性失血量。Objective To compare the hidden blood loss after minimaly invasive total hip arthroplasty（THA）by anterolateral approach（OCM technique）with the loss after lateral approach in THA.Methods Fifty patients（aged 29 to 93）were enroled in the study,22 were performed with OCM approach technique and 28 were with lateral approach. Total blood loss（ml）,hidden blood loss（ml）were evaluated. We also calculated percentage of hidden＆amp;nbsp;loss in total（%）according to the gross formula and compared hidden blood loss between the two approaches in THA.Results Conventional lateral approach group actual total blood loss was（1584.4±592.6）ml,the hidden blood loss was（981.7±345.3）ml,the hidden blood loss rate was 62%. OCM group,the actual total blood loss was（1408.4 ±518.1）ml,the hidden blood loss was（788.4 ±245.4）ml,the hidden blood loss rate was 56%. Between the two groups in the amount of bleeding during the operation,the OCM group,the hidden blood loss than the conventional lateral approach group were significantly reduced（P〉 0.05）.Conclusion OCM technique can significantly decrease the hidden blood loss after THA.
