Objective To explore the role of epiphyseal plate and cartilage whether or not to resist the invasion of osteosarcoma.tumor stage of invasion.mode of invasion and mechanism of genesis.

摘 要：目的探讨骨骺软骨板和关节软骨有无抵抗骨肉瘤侵犯的作用。

Results: Gd-enhanced MRI enabled to make differentiation between physeal and epiphyseal cartilage and reveal epiphyseal vascular canals.

结果：Gd增强MR成像能够区别骨骺软骨和生长板软骨，能够显示骨骺内的血管槽。

Methods. A validated 3-dimensional, nonlinear finite element model of an intact adult human L3-L4 motion segment was developed. Four fusion types were simulated using this model, including anterior lumbar interbody fusion, posterior lumbar interbody fusion, intertransverse process fusion, and interspinous process fusion.

制作一个完整的成人腰3-4节段三维立体多元化模型，再用这个模型来制成4种融合方式的模型，包括腰椎前路椎间融合、腰椎后路椎间融合、腰椎横突间植骨融合、椎板棘突间植骨融合；而且达到融合的程度也不尽相同。

Primary bone is a temporary tissue and is soon replaced by the definitive, lamellar variety of bone

初级骨是暂时性的组织，不久就为永久性的板层骨所代替。

The focus in long bone appears patchy geographic type, the courser of its long axis was coherent with the stress bone trabecula; the focus in vertebral bodies show laterigrade band-like which was distributed in the middle of the vertebral bodies or near the termibal lamella and plumbed with stress bone trabecula of the vertebral bodies.

在长骨灶病呈长斑片地图样，其长轴大体与应力骨小梁走行相一致；在脊柱椎体病灶表现为分布于椎体中央或近终板区的呈横形小片条带状，与椎体应力骨小梁排列垂直。

In the MRI group, MR images were taken and assessed for location and severity of defects of cartilage by Noyes classification, osteophytes, subchondral cysts, sclerosis, meniscal and/or ligamentous tears.

MRI组根据MRI影像诊断软骨缺损的部位，对软骨缺损严重程度进行Noyes分级，对韧带、半月板、骨赘和软骨下骨囊腔改变情况进行评定，并诊断是否属于前内侧骨关节病变。

Many osteoid were formed around metal surface and bone graft remodeling was active in 1 month as shown by nondecalcified section.

大体观察可见6个月时三翼臼植骨区表面与正常骨表面相仿，界限不清，可见三翼臼的翼板被骨组织包埋。

53 case of old fractures in maxillary bone was scanned by spiral CT. The treatment were determined by image of spiral CT scanning. Ostectomy and rigid internal fixation with mini Ti plate were applied to the patients of old fractures in maxillary bone according to part nad shape of fractures.

对53例上颌骨陈旧性骨折的患者进行螺旋CT检查，确定手术方案，重新截骨复位，应用微型金属钛板根据骨折的部位和形态行坚固内固定。

Results Extensive and diffuse synovial hyperplasia can be seen in patients with RA;synovial pannus formation can be seen in 25 cases.

结果RA组病人均可见广泛、弥漫的滑膜增生，其中25例病人可见滑膜血管翳形成，而OA组仅7例病人可见轻度滑膜增厚，未见滑膜血管翳形成者(X2=55.78P.005)；RA组关节软骨及软骨下骨改变较严重且弥漫，而OA组软骨退变则较局限，且以关节摩擦大的部位受损为著，其软骨下骨改变较为局限，常常见于IV软骨退变；关节腔积液、半月板及韧带改变，在OA组与RA组之间无差异。

Forty-sixe cases of symptomatic dynamic lumbar spinal instability were selected from the Ninth and Second People's Hospital from March 2003 to March 2007. They received dorsal spinal strenosis surgical decompression, titanium JJXA segmental pedicle screw fixation, intervertebral pace brace, intervertebral disc resection, with the sideward and the forward annulus fibrosus retained, endplate cartilage zone curetted, then received intervertebral bone particles graft, and pedicle screw compression. The patients were followed up for more than 15 months. The good and excellent rate was 91.3%.

选择2003-03/2007-03南阳市第九人民医院和南阳市第二人民医院收治的动力性腰椎不稳患者46例，行后正中入路下的椎管减压手术，钛制JJXA椎弓根螺钉置入，并行椎间隙撑开，双侧切除椎间盘保留侧方以及前方的纤维环，刮除终板的软骨层，行椎间颗粒骨植骨，椎弓根螺钉系统加压固定。46例随访时间≥15个月，优良率91.3%。
