[Abstrct] Objective The deformity of severe varus knee (varus angulation > 15°) can be treated by many ways in primary total knee arthroplasty , but the efficacy and cost are different. The topic of this study provides a new surgery: autograft (wedge grafts) implant and substitute medial tibial bone defects. Methods From Jan. 2006 to Jan. 2014 , a retrospective study was conducted in the First Affiliated Hospital of BaoTou Mendical College. Out of 687 patients, 721 primary knees were operated. Bone defects in proximal tibia (varus angulation >15° ) were encounted in 16 patients in 21 knees in the pattern of non-inclusive slope bone defects in the mean varus degree of 27°. Their IBM was 31 kg/m2. The average age of patients was (63 ± 5) years. The score of clinical knee society score (KSS) before operation was 18 on average. Among of them, the pain score were 12 points, the average range of motion (ROM) were 12 points. the average funtional score were 20 points. During operation,the slope bone defect of the medial tibial plateau was tailored into wedge-shaped ladder bone defect by osteotomy,and then the defect was filled with the resected tibial plateau autograft in which the thickness and shape were matched completely. The high-intensity cortical part of the autograft was placed in the rim to sustain the tibial prosthesis. Three months after operation ,patients started to walk without the help of crutch. Results The average followup period was 5.3 y , We observed that an average postoperative scores of clinical KSS from 42 points to 88 points with the score of functional KSS from 57 points to 92 points. Fusion was observed by trabeculae crossing from the graft to the tibial metaphysis on plain films at least 6 mouths without collapse, stress fracture, untight and bone ununion. Confirmation of vascularization of the graft was observed in bone scans of nuclide. showing increased uptake in the operated area. Inflammatory makers were normal. Conclusion Autograft (wedge grafts) reconstruction of medial tibial bone defects, is of high rate of healing in implant bones, good restoration of the function and low cost.

Objective To analyze the impact and quality of life of minimally invasive surgery combined with catheter attract surgery on patients with cerebral hemorrhage.Methods A total of 90 patients with cerebral hemorrhage in our department from February 2013 to De-cember 2014 were randomly divided into invasive group and the control group.Minimally invasive surgery group were given to cerebral hemor-rhage minimally invasive surgery combined with catheter attract surgery,the control group received traditional craniotomy.The postoperative recovery,nerve function scores,quality of life and morbidity between two groups were compared.Results The operation time and edema vol-ume of tissue postoperative 7 days in minimally invasive surgery group was significantly lower than those of the control group.The hematoma clearance rate 1 day after surgery was higher than that of control group,with statistically significant difference(P <0.05).NIHSS scores of two groups were gradually decreased 7 d,15 d,30 d after surgery(P <0.05).NIHSS scores of the minimally invasive surgery group 7 d,15 d, 30 d after surgery were lower than that of control group,with statistically significant difference(P <0.05).The scores of vitality,physiological function,physical function,general health,bodily pain,emotional function,social function,mental health after 6 months of the surgery in the min-imally invasive group was higher than those of control group,with statistically significant difference(P <0.05).The rate of postoperative pulmo-nary infection,electrolyte imbalance,gastrointestinal bleeding in MIS group were lower than those in the control group,with statistically signifi-cant difference(χ2 =5.400 0,4.405 7,4.615 4,P <0.05).Conclusion Minimally invasive surgery combined with catheter attract surgery can improve neurological function and quality of life for patients with intracerebral hemorrhage, and reduce the incidence of complications.

Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.
