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。
-
The calcar is a region of the femoral neck that extends caudal and lateral from the inferior femoral neck toward the lateral cortex.
股骨距是股骨颈从股骨颈内向外侧皮质延伸的基底和外侧部分。
-
The patients with higher BMD of the contralateral femur lost less bone, collar of the stem can reduce the extent of bone loss at the calcar region.
患者本身骨质量高者骨丢失少,假体肩托可部分减少股骨矩的骨丢失。
-
Results Harris hip scores improved from 53 to 95,thigh pain was 3.1%.Radiographic analysis revealed no evidence of osteolysis below the level of the calcar and the greater trochanteric region.Only 1 femoral stem was revised at 7 years postoperatively.
结果 所有患者平均Harris评分从58分提高到93分,大腿痛的发生率为3.1%。X线检查分析结果显示在股骨距以下水平没有发现明显的骨吸收现象,仅有1例在术后1年需要行股骨柄翻修。

1.It exists more higher stress in the cohere of handle and neck after various kinds prosthesis implantation,show this place is a key position;In the same time it shape a more higher stress dodge in the calcar femorale.
1各种假体植入后均在柄颈结合处有较高应力,提示该处是设计时的一个关键部位;同时股骨距处形成较高的应力遮挡。
-
However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale.
但是全髋关节置换后股骨近端应力负荷会发生改变,导致股骨近端的所谓"适应性骨重建",其特点是皮质骨变薄,骨密度下降,引起股骨近端假体周围,尤其是股骨距区骨丢失。
-
The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.
3动力髋螺钉虽然在固定强度上优于其它各组,但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用;自行设计的外固定支架为一种简单、有效、实用、经济的固定方法,有一定的推广价值;穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。
-
Bipolar hemiarthroplasty for intertrochanteric fracture is indicated for patients of more than 80 year old, thus the organic or systemic malfunctions should be corrected during perioperative period. Meanwhile, retaining of lesser trochanter and reconstruction of calcar femorale are of vital importance for improving periprosthetic biomechanics and reducing local complications.
人工股骨双动头置换术治疗股骨转子间骨折适用于80岁以上病人,因此在围手术期应尽可能纠正全身各器官及系统功能异常,同时,保留小粗隆并重建股骨距对改善假体周围生物力学及减少局部并发症具有重要意义。
-
(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.
(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法,不仅能考虑到所研究物体的几何形状,而且也考虑到物体的内部结构特性;股骨颈处的压力骨小梁和股骨距是重要的承载结构,内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入;载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处;一定角度的下肢外展(10-30°)会较明显的增加股骨颈区的应力,而下肢的内收反而会减小此区的应力;暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

The rate of excellent and good functional recovery of hip was 94.0%. Postoperative internal-fixation-related complications occurred in 31 cases, including hip varus in 14 cases who had posterior intertrochanteric fragments, delayed union of fracture in 12 cases who had fractured calcar and lesser trochanter and massive dissection of soft tissues, and cutting-out of lag screws in five cases, three of whom had to receive prosthetic replacement.
术后髋关节功能恢复良好率达94.0%。215例患者中31例出现内固定相关术后并发症,其中髋内翻14例,主要发生于股骨转子内后方存在明显骨折碎裂的患者;骨折延迟愈合12例,为骨折累及股骨距及小转子,术中做软组织广泛剥离、骨折复位固定的患者;内固定物股骨头颈内切割并螺钉穿入髋关节腔5例,其中3例再行人工关节置换,关节功能Harris评分为82分。
