查询词典 acetabular bone

Modify the model by FreeForm software and dissecte the model of haunch bone; import the 3D visible model of haunch bone into Ansys8.0 software. Add mechanics parameter to the haunch bone model, construct 3D finite element model of acetabulum. 2、On the base of common fracture line of acetabular posterior wall fracture in clinical cases, split the acetabular 3D finite element model according to 1/3, 2/3, 3/3 areas fractures of posterior wall after simplify setting, obtain four types of acetabular posterior wall fracture model(including normal condition of acetabulum).

按髋臼骨折Letournel分类标准并根据临床髋臼后壁骨折病例常见骨折线位置，进行简化设定，依次按后壁1／3，2／3，3／3面积骨折将髋臼三维有限元模型后壁进行拆分，获得三种髋臼后壁骨折状态的有限元模型；再模拟双足直立位对髋骨约束设定，分别对后壁正常及不同面积骨折状态模型进行加载，获取各模型应力分布图并记录臼顶负重区、髋臼前壁和剩余后壁在不同后壁骨折状态下应力分布大小及改变。

At 12–15 years, Charnley reported continuous radiolucent demarcation around cemented cups in 14% of patients.40 The failure rate was greatest in young patients, and Barrack and colleagues reported 44% loosening of cemented sockets at 12 years in individuals younger than 50 years.54 Cementless acetabular cups are hemispherical in shape and most are entirely porous-coated for bone ingrowth.

术后12-15年时，Charnley在14%患者中发现骨水泥髋臼杯周边存在连续的透亮线。年轻患者中假体失败率最高，Barrack报道为小于50岁的患者中术后12年时44%发生骨水泥套松动。非骨水泥髋臼杯为半球型，大部分全层喷涂多孔表面以促进骨长入。

Results: After a hundred thousand cycles of compression loads, the performing condition of small bone defect, parallel of a fin with force line, press fit implantation and three fins acetabular component fixed with three screws demonstrated a lest micromotion equaling 83 to 96 um.

结果：1、在压力负荷实验，经10万次加载686N压力载荷，采集100次、1000次、1万次、10万次假体微动位移，工况为小骨缺损面积—假体植入后翼与载荷力线平行—紧压配合植入—螺钉固定的三翼臼最为稳定，微动位移为83-96um，疲劳位移为151um。

Whether the original prothesis can be saved when fixed tightly with femur or acetabular bone needs more experiences to confirm.

对固定稳定、与周围骨质间无感染征象的的假体选择不翻修是否可行，有待更多病例的总结。

Conclusion］Good results can be obtained in hips with acetabular protrusion after reconstructed with autogeneous or allogeneous bone grafting and total hip arthroplasty.

结论］应用自体股骨头骨或异体颗粒骨移植填充髋臼连系多孔生物型髋臼假体，治疗Otto's病，可获得较好的疗效，移植骨可与宿主骨很好地连系在一路。

In patients with a large superior segmental bone deficiency, the resulting acetabular recess is elliptical rather than hemispherical, and a bilobed or oblong implant can be used instead of a large structural graft or excessiely high placement of a hemispherical component Fig.

髋臼上方有大块骨缺损的病人，其髋臼窝变为椭圆形而非半球形，因此可用双叶形或椭圆形假体替代大块结构性骨移植，或在高位植入半球形假体（图7－40，A）。

The manner of stress transfer from a cementless acetabular component to the surrounding acetabular bone dictates its initial stability.

应力从非骨水泥型髋臼假体传导至周围骨的方式决定了关节的初期稳定性。

Topography map of the hip bone displays the depth of all parts of the hip bone and the projection of important blood vessel and nerve onto the hip bone imaginarily and directly. Deep understanding of topography map of the hip bone may prevent vital blood vessel and nerve from accidental injury during the operation of internal fixation of pelvic fracture and acetabular fracture.

提示髋骨的地形图形象、直观地表达了髋骨各个部位的厚度、重要血管和神经在髋骨表面的投影，深入地了解髋骨的地形图能够在骨盆骨折和髋臼骨折内固定中防止重要血管和神经的意外损伤发生。

The radiographical evaluation was performed according to orthotropia and lateral images of hip joint to observe acetabular migration and bone changes around the hip and measure the polyethylene wear rate and direction of the acetabular polyethylene wear.

影像学评估根据术后及随访时髋关节正、侧位片，观察髋臼假体的位置及其周围的骨质改变，并测量臼杯的磨损速度、磨损方向。

Cadaeric studies show that self-tapping threads may wedge against the acetabular bone but seldom cut into the bone.

螺纹型髋臼配以多孔表面可能增加其固定效果。

Do you know, i need you to come back

你知道吗，我需要你回来
