股骨头

Of all these femoral heads,21 presented cystiform change,fragmentation and deformation of femoral head were found in 15,15 femoral heads associated with joint effusion.Conclusion:C...

CT在发现股骨头缺血性坏死的早期病变以及确定病变范围等方面优于普通X线，CT在早期诊治股骨头缺血性坏死中具有重要价值。

Pathologic changes leading to avascular necrosis of the femoral head are initiated in 2 broad categories of anatomic regions, intravascular and extravascular factors.

病理变化，导致股骨头缺血性坏死股骨头发起在2大类的解剖区域，内和外的因素。

expandable intramedullary nail system has the unique technique principle, which has "hourglass" effect of homogenic load distribution and the advantage of no need of reaming and interlocking as well as the high power of anti-rotation resulting from the head of the peg in the femoral head. The fixation of Fixion PF for peritrochanteric fractures in old patients is mini-invasive .

Fixion PF可膨胀髓内钉固定原理为沙漏样固定，应力均匀分布于股骨髓腔，股骨头栓钉于股骨头内膨胀，增加抗旋转能力，不需扩髓、远端交锁，其独特的设计原理可减少创伤和相关手术并发症，尤其适合于老年骨质疏松性股骨近端骨折的治疗。

Methods Homolateral bone flap with deep iliac circunmflex vessel was transplanted into the defect after clearing up cysts and sequestra of femoral head.

清除坏死股骨头囊肿、死骨后，采用显微外科技术切取同侧带旋髂深血管骨瓣植入股骨头内。

Methods:CT findings of 100 cases of normal hips were investigated randomly,meanwhile,the relation of femoral head and the prolonged line both anterior acetabulum labra,the femoral head abterior space,the femoral head posterior space were evaluated.

随机调查100例正常髋关节CT表现，观察和测量髋臼前唇连线与股骨头的关系以及股骨头前间隙和后间隙，与28例髋臼发育不良的CT片作对照。

T-text was applied for the normal groups and the displasia group. Results: There was significant statistical differentce between the normal group and the acetabulum displasia group by revealing the relations through measuring both femoral head front edges and anterior acetahulum labra line, the femoral head abterior space, and the femoral head posterior space.

结果：髋臼前唇连线与股骨头前缘的关系的测量值和股骨头前后间隙测量值在正常组和髋臼发育不良组之间对比具有统计学差异。

Recent research shows hip arthroscopy can provide early diagnosis and treatment hip unexplained pain, such as femoroacetabular impingement,labral tears, chondral lesions, furthmore hip arthroscopy shows good prospects in the treatment avascular necrosis of femoral head, synovial abnormalities, post hip arthroplasty discomfort.

研究表明，髋关节镜对于既往不明原因的髋痛如髋关节撞击征、髋臼盂唇、髋臼软骨损伤可以早期诊断和治疗。此外，髋关节镜在股骨头坏死、股骨头圆韧带损伤、髋关节置换后的应用也展现出极大的应用前景。

研究表明，镜关节镜对于既往不明原因的髋痛如髋关节撞击征、髋臼盂唇、髓臼软骨损伤可以早期诊断和治疗。此外，髋关节镜在股骨头坏死、股骨头圆韧带损伤、髋关节置换后的应用也展现出极大的应用前景。

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).

结果1，尸体LPEH髋关节模型的超声诊断敏感性、特异性分别为88％、84％，阳性预测值、阴性预测值分别为79％、91％。2，21例患儿的LPEH患髋(21侧)、健髋(21侧)，以及21例正常儿童健髋(42侧)的超声检查显示：髋关节周围软组织及股骨头无形态结构差别；股骨头软骨厚度无统计学差异(3.5±0.5mm vs.3.6±0.4mm vs.3.6±0.5mm，p＞0.05)；关节囊前层及后层厚度无统计学差异(前层厚度2.79±0.74 mm vs.2.56±0.40mm vs.2.56±0.72mm；后层厚度2.70±0.82mm vs.2.48±0.54mm vs.2.44±0.58mm，p＞0.05)，但LPEH患髋关节囊前、后层均较后二组有增厚趋势。3，LPEH患髋均存在关节腔内积液，且早期较为清晰；积液以髋关节内下间隙明显，内下间隙较前间隙明显增宽(12.50±4.04mm vs.4.35±0.8mm，p＜0.05)，其内见嵌顿滑膜唇皱襞呈稍强回声的占位性团块，长约15.6±5.6mm，宽约8.9±7.8mm，90.5％(19／21)嵌顿皱襞内未见血流信号。4，所有LPEH患髋治疗后超声复诊均显示正常。

MAIN OUTCOME MEASURES: Lacunae changes of osteocytes in femoral heads were detected with hematoxylin-eosin staining method, and the expression of Bcl-2 and Bax proteins with immunohistochemistry staining methods, after 3, 6, 12, 24, 48 and 96 hours of ischemia respectively.

主要观察指标：应用苏木精-伊红染色，免疫组织化学来观测股骨头缺血后3，6，12，24，48，96h股骨头内骨细胞陷窝变化及Bcl-2、Bax蛋白表达的变化情况。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
