骨髓腔

BACKGROUND: Prosthesis selection for total hip replacement is determined by geometrical matching with femoral medullary cavity of patients and the optimal biodynamics. It is of great significance for elevating outcomes of total hip replacement.

背景：人工髋关节置换术前选择假体时，不仅要考虑在几何学上达到与患者股骨髓腔的匹配，而且还要在生物力学性能上达到最优，这对提高全髋关节置换术后疗效，具有较现实的意义。

Neither was the material properties of cortical bone in tibia between the two groups at every stage of experiment.

卵巢切除对皮质骨的影响主要表现在使骨髓腔扩大，对骨外膜的影响较小，在短期内对皮质骨的力学性能无明显影响

The most stricture section is at 2cm above the midpoint between greater trochanter and lateral epicondyle, with the sagittal plane diameter being 10.56 1.49mm, and the coronal planediameter 10.08 1.67nnn.

大转子外下缘至外上髁之中点上2.0cm处骨髓腔最狭窄，矢状径为10.56±1.49mm，冠状径为10.08±1.67mm.2LRDCIN的钉体两侧有侧翼，主钉不带槽。

The results revealed that there was osteoporosis appeared at 6 weeks in rigid fixating segment.Bone lossing happened at Haver's system, bone absorption revealed after 10weeks on endosteal surface and enlargement of bone marrow. Osteoporosis and thinning of the cortex on fixating segment,especially under steel plate happened due to negative balance of remodeling process of the two surface of the bone.

结果发现：坚硬接骨板内固定后六周时固定段骨即出现骨质疏松，发生在哈佛氏系统的骨丢失，10周后骨内膜表面出现骨吸收、骨髓腔增大，两个表面的骨重建单位的负平衡使固定段皮质骨疏松变薄，特别是在钢板下。

Bones also store minerals, especially calcium and phosphorus, and fat cells in the marrow cavity can store lipids.

此外，骨骼还可作为矿物质的储存场所，尤其是钙。磷等，骨髓腔内的脂肪细胞也可储存脂质。

The section of the bone showed that the bone marrow cavity was fulled with tumor cells, and the cortical bone was destroyed.

组织学研究显示骨髓腔内肿瘤生长，向外侵蚀破坏骨皮质。

No delay in bone healing,no broken nails,the bone marrow cavity infection,fat embolism,joint stiffness and re-fracture,and other complications.

无骨折延迟愈合、无断钉、骨髓腔感染、脂肪栓塞、关节僵硬及再次骨折等并发症。

MAIN OUTCOME MEASURES: Number of trabecular bone closely or not closely connected by bone cement section surrounding to calculate the rate of combination; condition of surfaces of marrow cavity and bone cement in the column by amplifier.

主要观察指标：观察CT片，测出骨水泥截面周围与骨小梁结合紧密者与非结合者的个数，计算结合率。用放大器材观察骨髓腔内表面及骨水泥内柱表面情况。

Abstract］ objective to observe gentamicin pmma chain in the treatment of chronic osteomyelitis.methods the seven cases of chronic osteomyelitis patients,had thorough debridement therapy,implanted in the bone marrow cavity in the soft tissue around with gentamicin pmma chain,indwelling two weeks over.results cured five cases,two cases were effective.conclusion gentamicin chain is important in treatment of chronic osteomyelitis,recommends retaining three months.

目的 观察庆大霉素 pmma 珠链在慢性骨髓炎治疗中应用的临床疗效。方法对7例慢性骨髓炎患者，彻底清创治疗后，在骨髓腔内与周围软组织内植入庆大霉素 pmma 珠链，留置 2 周以上。结果治愈5例，有效2例。结论庆大霉素珠链是治疗慢性骨髓炎的重要方法，推荐留置 3 个月。

Radiographic signs of the disease are increase in density of bilateral bones, osteosclerosis with thickening of the cortex and stricture or obliteration of the medull...

本病的X线征为双侧骨骼的密度增高和骨质硬化，骨皮质变厚，骨髓腔变窄甚至闭塞。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
