文题释义:
髋臼假体置放位置:人工全髋关节置换置换过程中,需要对臼杯进行准确的置入。全髋关节置换的近期和远期效果均与假体,尤其是髋臼杯的安放位置有关。如果出现臼杯位置安放不当的情况,则很有可能会引起假体撞击、脱位、磨损等不良后果。精确测量髋臼假体位置,有助于提高术中假体安放的准确性。
髋臼前倾角、外展角:髋臼的解剖学外展角是臼杯开口平面与水平面的夹角。解剖学前倾角是髋臼轴在水平面上的投影与冠状轴的夹角。髋臼的影像学外展角是髋臼轴在冠状平面的投影与垂直轴的交角。影像前倾角是髋臼轴和冠状平面之间的夹角。解剖学外展角和前倾角也被称作髋臼的三维外展角和前倾角。
 
摘要
背景:全髋关节置换术中,需要对髋臼假体进行准确的置入,以保证假体的生存率,提高预后效果。为保证髋臼的准确置入,需要对其外展角和前倾角进行准确测量。
目的:探讨C臂X射线机移位测量髋臼前倾角、外展角在全髋关节置换术中的应用价值。
方法:纳入63例行全髋关节置换的患者,按患者意愿分为2组,对照组30例予以传统髋臼假体定位器置入,观察组33例在C臂X射线机移位测量后置入髋臼假体。置换前、置换术中、置换后分别对观察组的髋臼前倾角、髋臼外展角、骨盆倾斜度进行测量;置换后测量2组患者的髋臼前倾角和髋臼外展角,并记录2组不同时间点的疼痛评分和髋关节功能Harris评分。

结果与结论:①置换前、置换术中、置换后,观察组的髋臼前倾角、髋臼外展角、骨盆倾斜度差异均无显著性意义(P均> 0.05);②置换后2组的髋臼外展角差异无显著性意义(P > 0.05),但观察组的髋臼前倾角显著小于对照组(P < 0.05);③置换后7 d,观察组的目测类比评分低于对照组(P < 0.05);④与置换前比较,2组置换后的Harris评分均显著提高(P < 0.05);观察组置换后3,12个月的Harris评分均高于对照组(P < 0.05);⑤结果提示,全髋关节置换术中利用C臂X射线机进行髋臼前倾角、外展角移位测量可以对骨盆前后倾斜、内外旋转以及外展内收等予以有效纠正,提高髋臼杯安放的精确性和置换手术质量,改善预后。

Abstract:

BACKGROUND: In total hip arthroplasty, the accurate placement of the acetabulum is needed to guarantee the survival rate of the prosthesis and improve the prognosis. In order to ensure the accurate placement of the acetabulum, the accurate measurement of the abduction angle and the anteversion angle of the acetabulum is needed.

OBJECTIVE: To investigate the application value of C-arm X-ray displacement measurement of acetabular anteversion angle and abduction angle in total hip arthroplasty. 
METHODS: Totally 63 cases undergoing total hip arthroplasty were divided into two groups according to their will. Patients in the control group (n=30) were implanted with traditional acetabular prosthesis locator. Patients in the observation group (n=33) were implanted with acetabular prosthesis after C-arm X-ray displacement measurement. Acetabular anteversion angle, abduction angle and pelvic inclination were measured before, during and after arthroplasty. Acetabular anteversion angle and abduction angle were measured in both groups after arthroplasty. Pain score and hip function Harris score were recorded in both groups at different time points. 

RESULTS AND CONCLUSION: (1) No significant difference in acetabular anteversion angle, abduction angle and pelvic inclination was detected before, during and after arthroplasty (all P > 0.05). (2) No significant difference in abduction angle was determined between the two groups after arthroplasty (P > 0.05), but acetabular anteversion angle was significantly smaller in the observation group than in the control group (P < 0.05). (3) At 7 days after arthroplasty, Visual Analog Scale scores were less in the observation group than in the control group (P < 0.05). (4) Compared with that before arthroplasty, Harris score was significantly higher after arthroplasty in both groups (P < 0.05). Harris score was higher in the observation group than in the control group at 3 and 12 months after arthroplasty (P < 0.05). (5) Results indicated that during total hip arthroplasty, C-arm X-ray machine can measure acetabular anteversion angle and abduction angle, and effectively correct pelvic inclination, internal and external rotation, abduction and adduction, improve the accuracy of acetabular cup placement and the quality of replacement surgery, and improve the prognosis of the patients.
