骨髓腔

Infectious cavity or bone marrow cavity can be subjected to simple vacuum drainage for a prolonged 7~14 days.

感染性腔隙或骨髓腔可延长应用单纯负压管吸引7～14天。

Marrow cavity is the place where bone cement fusion takes place, so its preparation is important to improve bone cement filling quality.

摘要背景：提高骨水泥与骨界面的融合可降低假体松动率，骨髓腔是骨水泥融合中的接受腔，其准备过程是提高骨水泥充填质量的关键。

MRI examination found that the partial disappearance of cortical signals and the extensive abnormal signals from the marrow cavity.

MRI检查除骨膜改变外病变尚累及骨皮质和骨髓腔，骨干皮质信号部分消失，髓腔内显示广泛的异常信号。

OBJECTIVE: To observe effects of combined application of sublethal dose radiographic exposure, fludarabine and bone marrow transplantation in the marrow cavity on specific immunologic tolerance in rats undergoing limb allotransplantation.

目的：观察联合应用亚致死量放射线照射、氟达拉滨及骨髓腔内骨髓移植对诱导大鼠同种异体肢体移植产生特异性免疫耐受的影响。

OBJECTIVE: To evaluate bone cement-bone interface fusion in marrow cavity washed with high-pressure pulsed water syringe versus marrow cavity brushing.

目的：采用断层CT及大体观察评估骨髓腔用高压脉冲水枪冲洗及髓腔刷洗处理后骨水泥与骨界面的结合情况。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。

Anatomical studies of femoral endosteal geometry suggest that exact fit of a prosthesis within the cortex is implausible because of large ariations in anatomy and age-related changes in the diameter of the canal.

对股骨髓腔几何形状的解剖学研究表明，由于髓腔的解剖变异相当大并且其直径随年龄而发生改变，故要达到假体与骨皮质完全密贴是不太可能的。

BACKGROUND: Implantation of artificial joint of bone cement can result in long-term blocking of recipient site medullary canal and blood vessel lesion, and lead to changes in intraosseous pressure and bone blood flow of distal femoral shaft.

背景：骨水泥固定型人工关节假体骨腔内的植入必然涉及受区骨髓腔的长期闭塞和髓内血管的破坏，由此而产生的髓内压和血流的变化是材料本身的影响所致，很有研究价值。

In terms of pulmonary hypertrophic osteoarthropathy, Xray can only detect the periosteum hyperplasia and interosseous membrane calcification, while CT can show changes in the density of marrow cavity, MRI the abnormal signals of cortical bone and marrow cavity.

肺性肥大性骨关节病X线检查仅能发现骨膜增生和骨间膜钙化。CT检查可显示髓腔密度不均。MRI检查可显示病变累及骨皮质及骨髓腔。

The X-ray photo of animal experiment 2, 4 weeks after operation sees that the poroma of the skewed group is lesser and not concentrating while the poroma of the horizontal-shaped is much and concentrating, and 6, 8 weeks after operation the fracture line is blurred.

动物实验X片见术后2、4周斜形组骨痂较少且不集中，横形组骨痂较多且较集中，6、8周骨折线模糊，斜形组骨髓腔较不规则，横形组塑形较好，髓腔较规则。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
