【摘要】：目的探讨基于CT三维重建图像应用拟合分析法在人工全髋关节置换术(THA)中预测关节假体型号的准确性及应用价值。方法对21例(24髋)行THA治疗患者通过术前CT图像进行三维重建,采用拟合分析法预测假体型号,并与术中实际使用的假体型号进行比较。结果手术时间149~261 min,平均(179.90±116.40)min。4例术中输血,术中出血量平均(425.00±364.37)mL;术后住院时间(15.11±4.67)d;术中假体植入时无股骨或髋臼周围骨折;术后无下肢静脉血栓形成。患者均获随访,随访时间至少1年。患者疼痛症状均缓解,患肢功能显著改善。股骨头缺血性坏死患者Harris评分从术前(52±19)分提高至(92±13)分,差异有统计学意义(P0.05)。髋臼假体获优17例,良6例,差1例,优良率95.8%,差异无统计学意义(P0.05)。结论 THA术前在CT三维重建中应用拟合分析可以准确预测全髋置换术中髋臼假体型号,为术者选择合适型号假体提供参考。
[Abstract]:Objective to study the accuracy and application value of fitting analysis method in predicting the type of joint prosthesis in total hip arthroplasty (THA) based on CT 3D reconstruction image.Methods 21 cases (24 hips) treated with THA were reconstructed by CT images before operation. The model of prosthesis was predicted by fitting analysis and compared with the actual type of prosthesis used during operation.Results the operative time was 149 卤261 min, the average blood transfusion was 179.90 卤116.40)min.4, the average intraoperative blood loss was 425.00 卤364.37mL, the postoperative hospitalization time was 15.11 卤4.67mL, there were no femoral or periacetabular fractures during prosthesis implantation and no venous thrombosis in the lower extremity after operation.All patients were followed up for at least one year.Pain symptoms were relieved and limb function was significantly improved.The Harris score of the patients with avascular necrosis of femoral head increased from 52 卤19 to 92 卤13, and the difference was statistically significant (P 0.05).The acetabular prosthesis was excellent in 17 cases, good in 6 cases, poor in 1 case, the excellent and good rate was 95.8%, the difference was not statistically significant (P 0.05).Conclusion fitting analysis can accurately predict the type of acetabular prosthesis in total hip replacement by using fitting analysis in CT 3D reconstruction before THA, and provide a reference for the choice of suitable type of prosthesis in total hip arthroplasty.
