There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

结果(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度 mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2～5区和10～12区；气泡影出现在假体远端的3～5区和10～12区。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anterior-posterior plane and in Gruen zones 8,9 and 12 in the lateral plane. Typical areas of radiolucency were identified in Gruen zones 25 and 1012 in the middle-distal of the stem. Voids appeared in Gruen zones 35 and 1012 in the distal of the stem.

结果］(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度＜2mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2~5区和10~12区；气泡影出现在假体远端的3~5区和10~12区。

All lesions were 7-12 mm in greatest diameter. Seven cases showed a round radiolucency or a thin clear sclerotic rim in middle or up-outer of femoral neck on X-ray film.

结果：8例股骨颈疝窝均为单侧单发病灶，X线平片仅显示7例，CT均表现为股骨颈前方皮质下类圆形骨质缺损，内为较均匀液体密度，边缘清楚伴有硬化缘，最大径线为7-12 mm.7例在X线平片上表现为股骨颈中轴线或其外上方的类圆形透亮区或硬化环。

Spikelets laterally compressed, florets several, all bisexual or lowest sterile and without a palea; rachilla glabrous, disarticulating above glumes and sterile floret and between fertile florets; glumes lanceolate, shorter than lemmas, subequal or unequal, scarious-membranous, 1–3-veined, obtuse to acuminate or aristulate; lemmas ovate-lanceolate, scarious-membranous, 3-veined, long-ciliate on lateral veins, keeled, apex setaceously bidentate with a short, often recurved awn from the sinus; palea shorter than lemma, hyaline, keels very shortly ciliate.

小穗侧面压扁，小花数个，全部不育和没有一内稃的最低的两性的或；高于颖片和不结果的小花无毛，脱节的小穗轴和在肥沃的小花之间；披针形的颖片，短于外稃，近等长或不等长，干膜质膜质，1-3脉，具小芒的钝到渐尖或；卵状披针形，干膜质的外稃膜质，3脉，具长缘毛在侧脉上，龙骨状，先端setaceously具双齿具短，通常下弯从那里那些凹缺；内稃短于外稃，透明，龙骨非常短的纤毛。

Methods Before the operation, the angles between the spinous process and the pedicle of vertebral arch were detected, and used to decide the direction of screws in operation. 23 cases of thoracolumbar vertebra fracture were treated with AF system in this way.

术前对23例胸腰椎骨折X线侧位片及CT片进行研读，测量椎弓根与棘突的角度关系，指导术中椎弓根螺钉的植入方向。

If the dial indicator reads 0.14~0.3mm , it means the tooth clearance is right; You can also use a 15~20mm long and 0.5mm thick lead sheet or "∽"-shaped fuse . Put the sheet or fuse between the unengaged tooth flanks tha is between the convex surface of small bevel gear and the concave surface of the large bevel gear. Turn the gear, then the pressed thickness of the big lead sheet end suggests the normal tooth clearance of this site.

另一种方法是用长15~20毫米，厚0.5毫米的铅片或弯成"∽"形的保险丝，放入两齿轮非啮合的齿面之间（即小锥齿轮的凸面和大锥齿轮的凹面之间），转动齿轮，则铅片在靠近大端处被挤压的厚度即为该处的法向齿侧间隙。

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。

Presently, actinoscopy commonly used in stomatological clinic cannot provide the precise information of palatal bone thickness and bone mineral density such as toroidal slide plate photograph and skull lateral projection.

目前口腔医学临床常用的放射检查手段，如拍摄曲面断层片及头颅侧位片均不能提供腭部骨厚度及骨密度的确切信息。
