【摘要】：背景:全髖關節(jié)置換術中,需要對髖臼假體進行準確的置入,以保證假體的生存率,提高預后效果。為保證髖臼的準確置入,需要對其外展角和前傾角進行準確測量。目的:探討C臂X射線機移位測量髖臼前傾角、外展角在全髖關節(jié)置換術中的應用價值。方法:納入63例行全髖關節(jié)置換的患者,按患者意愿分為2組,對照組30例予以傳統(tǒng)髖臼假體定位器置入,觀察組33例在C臂X射線機移位測量后置入髖臼假體。置換前、置換術中、置換后分別對觀察組的髖臼前傾角、髖臼外展角、骨盆傾斜度進行測量;置換后測量2組患者的髖臼前傾角和髖臼外展角,并記錄2組不同時間點的疼痛評分和髖關節(jié)功能Harris評分。結果與結論:(1)置換前、置換術中、置換后,觀察組的髖臼前傾角、髖臼外展角、骨盆傾斜度差異均無顯著性意義(P均0.05);(2)置換后2組的髖臼外展角差異無顯著性意義(P0.05),但觀察組的髖臼前傾角顯著小于對照組(P0.05);(3)置換后7 d,觀察組的目測類比評分低于對照組(P0.05);(4)與置換前比較,2組置換后的Harris評分均顯著提高(P0.05);觀察組置換后3,12個月的Harris評分均高于對照組(P0.05);(5)結果提示,全髖關節(jié)置換術中利用C臂X射線機進行髖臼前傾角、外展角移位測量可以對骨盆前后傾斜、內外旋轉以及外展內收等予以有效糾正,提高髖臼杯安放的精確性和置換手術質量,改善預后。
[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.
