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。

Few branches and little femoral head blood perfusion were observed in all of retinacular arteries, while hip joint was internally rotated with the sick leg straightened in the patients.

对12例青壮年股骨颈骨折在2～5 d内进行旋股内、外及支持带动脉造影，造影中均采用中立位无牵引、中立位5 kg牵引及内旋位无牵引3种形式。

Results Intra-articular hemorrhage was observed in 1 patient and intra-osseous hemorrhage in 7 patients. The injury of retinacular arteries and reduction of blood supply were found in each case. In the presence of hip traction, blood flow of retinacular arteries reduced markedly. Few branches and little femoral head blood perfusion were observed in all of retinacular arteries, while hip joint was internally rotated with the sick leg straightened in the patients.

结果 12例中髋关节囊内出血1例，骨内出血7例， 12例均出现持带动脉损伤和血供减少；患髋牵引时支持带动脉供血减少；髋关节维持伸直内旋位时所有支持带动脉无明确显影或仅显示其主干。

The femoral circumflex arteriography of the normal leg was done in 8 patients, and three of them were simultaneously done in a postion of internal rotating of straight leg. Results Comparison with the arteriographic findings in absence of traction, all retinacular arteries but inferior arteries were depicted few branches and less femoral head perfusion in all 9 patients, especially in that of medial femoral circumflex arteriography, as hip joint was tractating in neutral position with the same speed and volume of injecting contrast medium and, the veins were demonstrated poorly or delayed.

结果同一血管部位，同等对比剂注射流率、总量造影，与中立位无牵引状态下造影所见比较，9例患髋中立位牵引时，除外下支持带动脉，所有未损伤的支持带动脉均有不同程度闭塞，相应股骨头颈部灌注不佳或几乎无灌注，静脉显影延迟或显示不清，4例牵引力由3kg增至5kg时，上述改变更为明显；5例患髋维持伸直内旋位时，所有支持带动脉尤其细小分支未见明确显示，股骨头灌注差或未见明确灌注，改变甚于牵引时；2例正常髋内旋位时造影改变类似。
