【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(P0.05),但观察组的髋臼前倾角显著小于对照组(P0.05);(3)置换后7 d,观察组的目测类比评分低于对照组(P0.05);(4)与置换前比较,2组置换后的Harris评分均显著提高(P0.05);观察组置换后3,12个月的Harris评分均高于对照组(P0.05);(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, it is necessary to implant the acetabular prosthesis accurately in order to ensure the survival rate of the prosthesis and improve the prognosis. Objective: to study the value of measuring acetabular anteversion by C-arm X-ray displacement in total hip arthroplasty. Methods: 63 patients with total hip replacement were included in this study. According to the wishes of the patients, the patients in the control group were divided into two groups: the control group (n = 30) was implanted with traditional acetabular prosthetic locator, and the observation group (n = 33) was implanted with acetabular prosthesis after C-arm X-ray displacement measurement. The acetabular anteversion angle, acetabular abduction angle and pelvic inclination were measured after replacement, and the acetabular anteversion angle and acetabular abduction angle were measured after the replacement. Results and conclusion the acetabular anteversion angle, acetabular outreaching angle and acetabular abduction angle were recorded in the two groups before and after the replacement. There was no significant difference in pelvic inclination between the two groups (P < 0.05). There was no significant difference in acetabular abduction angle between the two groups (P 0.05), but the acetabular anteversion in the observation group was significantly lower than that in the control group (P 0.05 / 3). The visual analogue score of the observation group was significantly lower than that of the control group at 7 days after the replacement. Compared with the control group, the Harris scores of the two groups were significantly higher than that of the control group, and the Harris score of the observation group was higher than that of the control group at 3 and 12 months after the replacement. In total hip arthroplasty, the acetabular anteversion angle was carried out by using C-arm X-ray machine. The displacement measurement of abduction angle can effectively correct the pelvic tilt, internal and external rotation and abduction, etc. Improve the accuracy of acetabular cup placement and quality of replacement surgery, improve prognosis.
