methods bone tumor models were induced by injection of vx2 carcinoma cell suspension into the medullary cavity of right tibias in 32 rabbits.

方法将新鲜的活vx2肿瘤组织制成肿瘤细胞悬液，经胫骨近端关节面穿刺将肿瘤悬液注入32只新西兰大白兔右侧胫骨中上段骨髓腔内，建立兔vx2骨肿瘤模型。

objective to discuss the effects of medullary cavity decompression combined with interventional therapy in treatment of femur head aseptic necrosis.

目的探讨应用髓腔减压加介入疗法治疗股骨头无菌坏死的效果。

it is a general practice of the orthopaedic surgeons to strip the periosteum, to ream the medullary cavity etc, which may easily cause injury of the nutrient artery of the long bones.

骨膜剥离和髓腔扩大是骨科手术中常用的操作方法，滋养动脉在手术中受到损伤时也需结扎。

animal model establishment: established the rabbit model whose proximal and middle femoral medullary cavity of left side was infused with pmma while the right side served as the control.

方法：1。动物模型建立：采取兔单侧（左侧）股骨髓腔内灌注pmma骨水泥而另一侧（右侧）不灌注作为正常对照的方法，制作骨水泥阻塞股骨近中段骨干髓腔的兔动物模型。

objective to explore the effect of low constant direct current (lcdc) in the medullary cavity on repairing of rabbit radial defect as to evaluate its clinical value.

目的探讨髄腔内恒定低压直流电刺激对家兔桡骨缺损的修复作用及其临床应用价值。

it involved four components those were expanding medullary cavity with drills and femur preparation with metal rasps and bone cement filling and prosthesis or intramedullary pin insertion.

股骨髓内操作包括了四个主要内容：可弯曲的软鉆扩髓，带齿的实心金属锉锉髓腔，骨水泥的填充，人工假体或髓内钉的置入。

conclusion the medullary cavity vessel could repair the femoral head, so a good environment is very important, and the vessel grafting maybe just accelerate the process.

结论髓腔血供可修复股骨头，故提供血管修复的环境很重要，而股骨头坏死治疗中血管植入可能只起加快修复作用。

scope of application: apply to openness wound surface rinse, surgical operative field rinse and medullary cavity rinse.

conclusion one-stage bone grafting filling medullary cavity after over-reaming is an appropriate method for pandiaphyseal osteomyelitis and can win high healing rate.

结论髓腔超扩植骨封闭方法治疗全骨干骨髓炎是可行的，可以获得较高的成功率。

in blank control group, medullary cavity was closed and bones were not connected.

空白对照组髓腔封闭，形成骨不连。

the arc of the tibial medullary cavity should be taken into account as a factor for intramedullary nail design.

④胫骨骨髓腔的弧度变化应成为髓内钉设计的考虑因素。
