Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.

目的 探讨非骨化性纤维瘤的x线表现以提高诊断水平。方法所有病例均摄有x线平片，分析经病理证实的8例非骨化性纤维瘤。结果临床症状轻，好发于下肢长骨干骺端或骨干，股骨4例，胫骨3例，肱骨1例。皮质型5例，表现为皮质内或紧贴皮质下的单层或多层透亮区，病变向骨内发展进入髓腔，周围有致密硬化带环绕，以髓腔侧明显；髓质型2例，病灶在骨内中央发展，显示为单房或多房透亮区，边缘有硬化，骨皮质菲薄，轻微向周围膨隆。结论 x线为最基本的检查方法，典型病例x线平片结合临床症状即可明确诊断。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

At 4 weeks following implantation, cells on the surface of coralline hydroxyapatite were found and connective tissues were seen in the material pores in the experimental group. Cells on the coralline hydroxyapatite were observed only in the control group. At 8 weeks, new bone formation was detected on the surface of coralline hydroxyapatite; bony tissue deposition and a few chondroid tissues were found in the pores or surrounding the pores in the experimental group. A few fibrous connective tissues were observed in the control group. At 12 weeks, abundant mature woven bone was detected on the surface of coralline hydroxyapatite; medullary cavity-like structure and vessels were found in some regions in the experimental group. No new bone or bony tissues were found in the control group.
