【摘要】：目的探索3-D打印個性化髖關(guān)節(jié)精確制備模板在全髖關(guān)節(jié)置換中的應(yīng)用。方法納入行首次全髖關(guān)節(jié)置換的患者40例,分為模板組20例和常規(guī)組20例。模板組術(shù)前行髖關(guān)節(jié)三維CT掃描,獲取患者CT原始數(shù)據(jù)資料,應(yīng)用Mimics16.0軟件建立患者髖關(guān)節(jié)模型,模擬THA手術(shù)過程并設(shè)計手術(shù)相關(guān)的患者個性化的制備模板,利用3-D打印機以Visijet M3 Crystal為材料打印出制備模板,將模板應(yīng)用于THA中,常規(guī)組不應(yīng)用模板。比較兩組患者的臨床結(jié)局,探究3-D打印個性化制備模板應(yīng)用在全髖關(guān)節(jié)置換術(shù)中的作用。結(jié)果兩組患者在一般資料、術(shù)前Harris評分、術(shù)前髖臼解剖數(shù)據(jù)方面無明顯差異。模板組在髖臼外展角偏離值和前傾角偏離值、頸干角偏離值、雙下肢不等長發(fā)生率方面明顯低于常規(guī)組,但是在手術(shù)時間、術(shù)中出血量、術(shù)后4周Harris評分方面模板組與常規(guī)組無明顯統(tǒng)計學差異。結(jié)論借助3-D打印制備的患者個性化制備模板在全髖關(guān)節(jié)置換術(shù)中可獲得一定精確性,有利于假體安放在與術(shù)前計劃匹配位置,提高手術(shù)質(zhì)量。
[Abstract]:Objective to explore the application of 3-D printed personalized hip precise preparation template in total hip arthroplasty. Methods 40 patients with first total hip replacement were included. The patients were divided into two groups: the template group (n = 20) and the routine group (n = 20). Three dimensional CT scanning was performed before operation in the template group, the original CT data of the patients were obtained, and the hip joint model was established by Mimics16.0 software. The process of THA operation was simulated and the individualized template was designed. The template was printed out by 3-D printer with Visijet M3 Crystal. The template was used in THA, but not in the routine group. The clinical outcomes of the two groups were compared. Objective: to explore the role of 3-D printed personalized template in total hip arthroplasty. Results the patients in both groups were evaluated with general data and preoperative Harris score. There was no significant difference in the anatomic data of acetabular before operation. The deviation value of acetabular abduction angle, anteversion angle, neck shaft angle, and the incidence of unequal length of both lower limbs in the template group were significantly lower than those in the routine group, but the operative time and the amount of blood lost during operation were significantly lower in the template group than in the conventional group. There was no significant difference in Harris score between the template group and the routine group 4 weeks after operation. Conclusion the individualized template made by 3-D printing can obtain certain accuracy in total hip arthroplasty. It is beneficial for the prosthesis to fit with the preoperative plan and to improve the quality of the operation.
