To explore the effect of hip joint center on the stability of hip joint,the radiographic measurements were compared between preoperation and postoperation.

通过手术前后对髋臼旋转中心的X线测量，探讨髋臼旋转中心的变化对髋关节平衡稳定性的影响。

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。

Figure 7-13 Creep, wear, and difficulty in roentgenographically determining cup wear. A, Roentgenographic findings in 66-year-old patient suggestie of cup wear compared with roentgenograms taken 9 years earlier .

图7－13。蠕变、磨损以及X线确定臼杯磨损的难点，B：66岁病人，与9年前所拍X线片比较提示臼磨损。

The key of preventing redislocation was:analyzing pathological change of hip dislocation in every patient correctly,selecting true operation type,intercepting bone rotatively below femur trochanter,diminishing angulus acetabularis and keeping relationship of cocenric circle between femoral head and acetabulum.

正确分析每一例患儿引起髋关节脱位的病理变化，选择正确的术式，行股骨粗隆下旋转截骨，减小髋臼角，使股骨头与髋臼保持同心圆关系，是预防再脱位的关键。

Aryl tetralin of lignans in podophyllotoxin has significant anti-tumor activity, which podophyllotoxin glucoside derivatives etoposide (VP-16) and teniposide (VM-26) is widely used in clinical.

芳基四氢萘类木脂素中的鬼臼毒素具有显著的抗肿瘤活性，其中鬼臼毒素的糖苷衍生物etoposide(VP-16)和teniposide (VM-26)被广泛用于临床。

Conclusions］Complex acetabular fractures with displacement should be evaluated by means of 2D rconstruction and three-dimensional multislice spiral CT.However 3D CT is of little practical value in undisplaced acetabular fractures.

结论］对于有移位的髋臼骨折尤其是复杂的骨折，应尽可能行二维及三维CT重建协助完善术前准备，三维CT对无移位的髋臼骨折实用价值不大。

The methods for determination of anteverted and abducted angle of acetabula in the positive X-ray films of hip joints are accurate and objective,simple.

结论在髋关节正位X线片上测算髋臼前倾角、外展角的方法是准确客观的，该方法简单易行，从而使THR术中髋臼假体的安置更加精确。

The obtained hip CT data were developed with SSD and MPR to observe spational position and bone stock of the acetabula.

对扫描获取的原始髋关节图像应用SSD 结合MPR 技术，观察髋臼的空间位置和髋臼壁骨贮备情况。

Methods Passing through the measurement of anteverted and abducted angels of acetabula in positive radiograms of 40 hip joints, compared with the practical values of anteverted and abducted angels of pelvis specimen,demonstrating the accurency of these kinds of measurement.

方法通过20具(40髋)骨盆标本髋关节正位X线片髋臼前倾角、外展角的测算值与骨盆标本髋臼前倾角、外展角的实际值相比较，以证明该测算方法的准确性。

Podophyllotoxin exists primarily on the Berberidaceae perennial herb group podophyllotoxin Bajiaolian a subfamily, Sinopodophyllum emodi a mountain of leaves and grass is a foot of the plants.

鬼臼毒素主要存在于小檗科多年生草本类群鬼臼亚科八角莲属、桃儿七属、山荷叶属及足叶草属植物中。
