您要查找的是不是：
- femoral component rotation 股骨假体旋转
- Prediction of the suitable size of the femoral component is an important task in the preoperative planning of THR. 术前选择与髓腔相匹配的股骨假体型号是THR术前计划的重要内容。
- Recent outcome of cortical strut allograft in the femoral fractures of distal end of femoral component after total hip replacement. 同种异体皮质骨板治疗全髋关节置换术后股骨假体远端股骨骨折的近期疗效观察。
- They identified failure to cover all reamed bone with the femoral component as the most important factor leading to fracture. 他们认为假体未完全覆盖研磨股骨颈为股骨颈骨折最重要的易感因素。
- The primary function of the femoral component is the replacement of the femoral head and neck after resection of the arthritic or necrotic segment. 股骨假体的主要功能是替换因关节炎或坏死而被切除的股骨头和颈部。
- Conclusions: This study demonstrated excellent durability of a prosthesis consisting of a cemented, collared, polished femoral component and a cementless acetabular component. 结论：本研究表明，抛光、带领的骨水泥股骨假体和非骨水泥髋臼假体的组合具有非常好的耐用性。
- Background: A theoretical advantage of resurfacing arthroplasty of the hip is that a failed femoral component can be safely and successfully revised to a total hip arthroplasty. 研究背景：髋关节表面置换理论上的优势是一旦股骨假体失败后可以安全且成功地翻修成全髋关节置换。
- Background: A theoretical adantage of resurfacing arthroplasty of the hip is that a failed femoral component can be safely and successfully reised to a total hip arthroplasty. 研究背景：髋关节表面置换理论上的优势是一旦股骨假体失败后可以安全且成功地翻修成全髋关节置换。
- Therefore excess body weight and increased physical actiity add significantly to the forces that act to loosen, bend, or break the stem of a femoral component. 因此，身体过重和体力活动过量可明显增加髋关节受力，从而导致股骨假体的松动、弯曲或柄的折断。
- Static factors include patellar implant position, femoral component alignment, configuration of the prosthetic trochlear groove, and soft tissue balance. 静态因素包括了髌骨假体的植入位置、股骨假体的相对位置、假体滑车沟的结构以及软组织的平衡。
- Objective To study the rotation of femoral component and tibial component with CT and evaluate the relationship between patellofemoral complications and rotational alignment of the components. 摘要目的应用CT技术测量股骨假体和胫骨假体旋转角度，探讨假体旋转性和髌股关节并发症之间的关系。
- Increasing the width of the proximal portion of the stem to better fill the metaphysis increases the torsional stability of the femoral component, especially when it is implanted without cement. 增加股骨柄近端的宽度以更好地填充干骺端可增加股骨假体的抗扭稳定性，特别是无骨水泥固定时。
- The presence of a collar on cementless femoral components is more controersial because it may preent complete seating of the stem, thereby making it loose at implantation. 无骨水泥固定股骨假体的颈领仍有较大争议，因其可能阻碍柄完全插入髓腔，从而在植入时就发生松动。
- With concerns about fatigue strength of porous implants, ion release, and aderse femoral remodeling, some cementless femoral components hae been fabricated without porous coating. 考虑到多孔表面假体的疲劳强度、离子释放和不良股骨重建，一些无骨水泥固定股骨假体已取消了多孔表面。
- The seasons follow each other in rotation. 四季循环交替。
- Seeral types of calcar replacement femoral components, as illustrated in Fig. 7-33 , are aailable for patients with loss of arying amounts of the proximal femur in lieu of the use of bone grafts. 如图7-33所示，几种带股骨距的股骨置换假体可用于股骨近端有不同程度骨缺损的病人，以替代骨移植。
- A rotation of personnel; crop rotation. 员工的轮流替换; 农作物的轮作
- The rotation of crops keeps the soil healthy and fertile. 谷物轮种使土壤保持了肥力和高质。
- Surprise is an essential component of my plan. 我这项计划主要就是想使大家惊喜一下。
- The sun appears to rise and set because of the earth's rotation. 因为地球在自转,看上去就有了日出和日落。
