摘  要:目的 探讨人工全髋关节置换术(total hip arthroplasty,THA)中影像监测控制假体放置的方法,提高初次THA假体置人的精确度。方法2000年4月~2005年8月,采用影像监测术中控制假体置人技术组(imaging,Ⅰ组)THA69例75髋,男32例,女37例;年龄46~75岁,平均62.3岁。同期采用通用技术组(standard,S组)THA72例78髋,男33例,女39例;年龄43~75岁,平均60.5岁。患者术前诊断为股骨颈骨折(GardenⅢ、Ⅳ):Ⅰ组23例23髋。S组25例25髋;髋臼发育不良(Campbell Ⅰ、Ⅱ):Ⅰ组9例10髋,S组11例13髋;骨性关节炎:Ⅰ组16例17髋,S组15例15髋;股骨头坏死(FicatⅢ、Ⅳ):Ⅰ组15例16髋,S组17例17髋,类风湿关节炎:Ⅰ组6例9髋,S组4例8髋。其中骨水泥型假体Ⅰ组21髋,S组22髋;非骨水泥型假体Ⅰ组12髋,S组11髋;混合型假体Ⅰ组42髋,S组45髋。Ⅰ组采用通用技术加术中X线透视控制假体置入,对臼外倾角、臼前倾角、颈长度和偏心距进行量化性监测。S组采用目测加定位器控制假体置入。对两组患者的手术切口长度、出血量、输血量、手术时间、X线透视次数、感染、术后功能恢复以及术后X线影像监测假体位置进行比较。结果 Ⅰ组随访60例65髋,S组63例69髋,随访时间6个月~5年4个月,平均随访时间Ⅰ组3.6年,S组3.7年。两组的手术切口长度、出血量、输血量、手术时间、X线透视次数以及术后X线评价假体位置、术后1年功能恢复差异有统计学意义(P〈0.05),Ⅰ组THA效果明显优于S组。结论影像监测THA能显著提高假体放置的精确度,减少不良的THA手术。拥有C臂X线透视机的县级医院可以开展这种技术。Objective To explore the intraoperative imaging to monitor the prosthetic fixation for the total hip arthroplasty (THA) and to increase the accuracy of the primary THA prosthetic fixation. Methods From April 2(300 to August 200,5, 69 patients (75 hips) underwent THA monitored by the imaging (the imaged THA group, Group Ⅰ), and 72 patients (78 hips) underwent THA with the standard method (the standard THA group, Group S). There were 32 males and 37 females in Group S. The mean ages of the patients in Group I and Group S were 62.3 years and 60.5 years respectively, ranging 46-75 years in Group Ⅰ and 43 75 years in Group S. Preoperative diagnoses were femoral neck fracture (Garden Ⅲ ,Ⅳ) in 23 patients (23 hips) in Group I and 25 patients (25 hips) in Group S, acetabular dysplasia (Campbell Ⅰ ,Ⅱ) in 9patients (10 hips) in Groupland 11 patients (13 hips) inGrouopS, osteoarthritisin 16 patients (17 hips) in Group I and 15 patients (15 hips) in Group S, femoral head osteonecrosis (Ficat Ⅲ ,Ⅳ) 15 patients (16 hips) in Group I and 17 patients (17 hips) in Group S, and rheumatoid arthritis in 6 patients (9 hips) in Group 1 and 4 patients (8 hips) in Group S. There were 21 hips of cement prostheses in Group I and 22 hips in Group S, 12 hips of cementless prostheses in Group I and 11 hips in Group S, 42 hips of cement and cementless prostheses in Group I and 45 hips in Group S. Group I used the standard THA and the intraoperative X-ray monitoring the prosthetic fixation in the numerical measure of abduction angle, anteversion angle, femoral neck length, and femoral offset distance. The items compared betweem C-roup I and Group S included incisional length, intraoperative bleeding, transfusion, operative time, frequency of X ray imaging, infection, postoperative functional recovery, and prostheric position of postoperative X-ray imaging. Results The follow-up on 62 patients in Group Ⅰ and 64 patients in Group S for 6 -64 months average
