髋臼骨

Irregularity of acetabulum increases cement-bone surface contact and reduces pressure per unit of surface.

髋臼不规则可增加骨水泥－骨的表面接触面积并降低单位表面的压力

Methods: We retrospectiely analyzed twenty-four hips in twenty patients who underwent a Bernese periacetabular osteotomy, which was done with a proximal femoral algus-producing osteotomy in thirteen hips, for the treatment of acetabular dysplasia associated with proximal femoral structural abnormalities.

我们回顾性分析20位患者中的24例髋关节，他们都进行过Bernese periacetabular截骨术，对于髋臼发育不良合并股骨近段的结构异常分别在13例髋关节完成了股骨近段外翻截骨成型术。

Osteotome is placed medial to iliac crest in preparing to resect graft. B, After

将骨刀插入髂骨内侧准备切取植骨块； B 髋臼和股骨头已经去除软骨面，在髂

Methods 48 joints of 43 cases of such patient were underwent salter resection,joint cover and combined operation.

方法采用Salter髋骨截骨法，髋臼加盖成形术和联合式手术方法治疗患儿43例48髋。

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。

Cementless femoral and acetabular components were designed to provide adequate initial stability and to encourage bone to osseointegrate onto or into the implant.

非骨水泥股骨和髋臼假体的设计目的为提供足够的初始固定和促进骨长入假体或长在假体表面。

The animal model can be established through transverse osteotomy at bilateral iliopectineal crest,which is an effective method to study the mechanism of compression and bone formation at pelvis and acetabulum.Anatomic fixation and persistent compression corresponding with physiological line of force with ATMFS can promote bone union.

通过双侧髋臼臼顶上方的横形截骨能够建立可靠的骨盆弓状线部骨折动物模型，ATMFS的解剖位固定和其产生的持续顺应生理力线的压应力能够促进骨折愈合。

Methods From December 2004 to May 2005, 9 cases of bone defectwere repaired with Osteoset pellets; bone defect was caused by benign tumor inlimbs, including 3 cases of fibroma xanthomas in humerus(1 case) and acetabulum (2 cases), 2 cases of bone cysts in humerus(1) and radius(1), 1 case of nonossifying fibroma, 1 case of ossifying fibroma and 2 cases of osteofibrous dysplasia in femurs.

2004年12月～2005年5月，采用Osteoset颗粒作为骨移植材料治疗9例四肢良性肿瘤性骨缺损，其中肱骨黄色纤维瘤1例，髋臼黄色纤维瘤2例，肱骨骨囊肿1例，桡骨骨囊肿1例，股骨非骨化性纤维瘤1例，股骨骨化性纤维瘤1例，股骨骨纤维结构不良2例。

Radiographical evaluation showed one hip with focal osteolysis, mean linear wear rate of 0.15 mm/ year and mean 10.4° for angle with vertical line.

影像评估显示1髋出现局灶性骨溶解；聚乙烯内衬平均线性磨损率为0.15mm／年，与垂线的成角平均为10.4 ；髋臼外展角平均为46 ；垂直距离平均为10.5mm，水平距离平均为8.7mm。

Evaluate MRI representation:(1) segregation condition: transfixation band, segregation between cartilage and bone, segregation between bone and bone;(2) four stages of pathologic classification based on MRI signal character;(3) texture in weight bearing zone;(4) add Bone Marrow Edema score and joint effusion score as stasis index.

术前MRI评估：(1)股骨头内分离情况：贯穿带、软骨与骨分离，软骨下骨与骨分离；(2)股骨头内信号的病理分期；(3)冠状正中位的髋臼负重区下结构；(4)将股骨头骨髓水肿评分和关节积液评分相加记为关节的瘀积指数。
