Application value of 3D printing guide plate in superPATH technology for elderly hip arthroplasty: Retrospective study and evidence analysis of literature retrieval / 中国组织工程研究

BACKGROUND: Hip arthroplasty is now an effective method of effectively solving the problem of femoral neck fracture in the elderly, but there is a risk of big trauma, high joint dislocation and postoperative complications. OBJECTIVE: To explore the application value of 3D printing guide plate in hip arthroplasty in the elderly by retrospective study and literature retrieval. METHODS: (1) Clinical data of 25 elderly patients with femoral neck fracture undergoing hip arthroplasty from February 2017 to October 2018 in Liaoning Jinqiu Hospital were retrospectively analyzed. In the guide plate group, 13 patients received hip arthroplasty using 3D printing guide plate. In the non-guide plate group, printing guide plate was not used in 12 cases. The application value of SuperPATH technique with 3D printing guide plate in hip arthroplasty in the elderly was observed. (2) Wanfang database was retrieved by the first author for studies published from 2000 to 2019. The key words were “3D, hip”. According to the inclusion criteria, 31 articles were selected to analyze the application value of 3D printing guide plate in hip arthroplasty in the elderly. RESULTS AND CONCLUSION: (1) The results of retrospective analysis showed that the operation time and the times of X-ray fluoroscopy were less in the guide plate group than those in the non-guide plate group (P 0.05). (2) Literature search results showed that 3D guide plates could be used to compensate for some defects of surgery in hip arthroplasty. There are many approaches to implement joint arthroplasty. Both conventional and minimally invasive approaches have direct anterior approach and posterolateral approach. According to several literature analysis, direct anterolateral approach can reduce trauma, and minimally invasive approach can reduce the risk of surgery. The above results show that the use of 3D printing guide plate in elderly hip arthroplasty can reduce the operation time and the times of intraoperative X-ray fluoroscopy, and the effect is better. 3D guide plate has application value in hip arthroplasty, and it has advantages in combination with minimally invasive techniques.

Application of operation bed and C-arm digital metrology adjustment in the percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures / 中国骨伤

OBJECTIVE@#To explore the application effect of operation bed and C-arm digital metrology adjustment in percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures.@*METHODS@#Ninty-four patients with osteoporotic thoracolumbar vertebral fractures admitted to our hospital from February 2015 to February 2017 were divided into control group and observation group according to random number table method, with 47 cases in each group. Control group adjusted C-arm and operating bed based on experience. For observation group surgical bed and C arm were measured and adjusted digitally and metrologically during percutaneous vertebroplasty. The operation time, times of fluoroscopy, hidden blood loss and bone cement volume were recorded in two groups. The clinical efficacy of two groups was observed by visual analogue score (VAS) and Oswestry Disability Index(ODI). Cobb angle and height of injured vertebrae before and after surgery were analyzed by imaging data.@*RESULTS@#The operation time, times of fluoroscopy, and hidden blood loss were significantly lower in observation group than in control group (0.05); VAS and ODI of observation group were significantly lower than that of the control group(<0.05); there was no significant difference in Cobb angle and height of injured vertebrae before and after operation between two groups. There were 3 cases of cement leakage, 1 case of urinary tract infection, 1 case of pulmonary infection, 2 cases of bedsore in observation group with complication rate was 14.89%(7/47); there were 8 cases of cement leakage, 2 cases of spinal nerve injury, 1 case of urinary tract infection, 3 cases of pulmonary infection, 2 cases of bedsore in control group with complication rate was 34.04% (16/47). The incidence of complications in observation group was significantly lower than that of control group (<0.05).@*CONCLUSIONS@#Operation bed and C-arm digital metrology adjustment can improve the surgical effect in percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures and promote rapid recovery.

The diagnostic value of transbronchoscopic lung biopsy without X-ray fluoroscopy in patients with perlpheral pulmonary lesions / 中国医师进修杂志

ObjectiveTo investigate the diagnostic value of transbronchoscopic lung biopsy (TBLB) without X-ray fluoroscopy in patients with peripheral pulmonary lesions.Methods Fifty patients with peripheral and diffuse pulmonary lesions and without cavity lesions from January to December 2011 were selected and examined by conventional hronchoscopy.According to the anatomical orientation of CT image and bronchial tree path,TBLB was performed by electronic bronchoscope.ResultsThere were 63 cases of TBLB in 50 patients and 30 patients got confirmed diagnosis (60.0％),including 24 cases in 35patients with peripheral pulmonary lesions (68.6％),and 6 cases in 15 patients with diffuse pulmonary lesions (40.0％).There was no severe complication during and after electronic bronchoscopy.ConclusionsTBLB without X-ray fluoroscopy is a convenient,safe and repeatable operational method with fewer complications.It has higher clinic diagnostic value in pulmonary diseases.

Under digital fluoroscopic guidance multiple-point injection with absolute alcohol and pinyangmycin for the treatment of superficial venous malformations / 介入放射学杂志

Objective to investigate the therapeutic efficacy of multiple-point injection with absolute alcohol and pinyangmycin under digital fluoroscopic guidance for superficial venous malformations. Methods By using a disposal venous transfusion needle the superficial venous malformation was punctured and then contrast media lohexol was injected in to visualize the tumor body,which was followed by the injection of ethanol and pinyangmycin when the needle was confirmed in the correct position. The procedure was successfully performed in 31 patients. The clinical results were observed and analyzed. Results After one treatment complete cure was achieved in 21 cases and marked effect was obtained in 8 cases,with a total effectiveness of 93.5%. Conclusion Multiple-point injection with ethanol and pinyangmycin under digital fluoroscopic guidance is an effective and safe technique for the treatment of superficial venous malformations,especially for the lesions that are deeply located and ill-defined.

Treatment of body surface venous malformations by local injection of Pingyangmycin lipiodol emulsion under fluoroscopic guidance / 医学研究生学报

Objective: To evaluate the method,efficacy and complication of fluoroscopic guided local injection of Pingyangmycin lipiodol emulsion(PLE) in the treatment of body surface venous malformations(VM).Methods:Forty cases of VM,including 22 cases in the maxillofacial region,5 cases in the trunk and 13 cases in the extremities,received PLE local injection under X-ray fluoroscopy.PLE was prepared by mixing 2-8 mg of pingyangmycin(PYM)with 2-8ml of ultra-fluid lipiodol,the dosage was determined by the size of lesions.The effects and complications of PLE treatment were observed. Results:Signs of VM were patches of abnormal venous opacification and washout delay of contrast medium.Thirty four cases received single injection of PLE and 6 cases were injected twice.Excellent and good results were obtained in 20 cases and 16 cases respectively after 6 months post-injection,the therapy was ineffective in the rest four cases.Total efficacy was 90 percent.There were no severe complications such as skin necrosis or ectopic embolization. Conclusion: PLE intra-vascular injection under fluoroscopic guidance was convenient and safe for body surface VM.The merits of PLE treatment include accurate(localization,) safety,and excellent curative effect.
