Since then, people have made many studies on resorbable internal bone fixation composites. Up till now, however, although those kinds of resorbable internal fixation composites have considerable strength, they can only be used for curing cancellated bone fracture and not for load-bearing bone fracture internal fixation because of their low modulus, too slow degradation rate and inflammation reaction.

然而到目前为止，可降解吸收性骨内固定材料，虽然具有一定的强度，但因刚度低，故在临床上仅用于治疗松质骨骨折，尚不能用于承重骨骨折的内固定，且在体内降解吸收时间太长以及容易引起无菌性炎症反应等，使其应用范围受到限制。

9GPa respectively, and those of random short fiber composites are 145MPa and 13. 0GPa respectively. Therefore, the initial mechanical capability of unidirectional long fiber and short fiber composites of CPP/PLLA is able to satisfy the requirement of mechanical capability of internal bone fixation materials for cortical bone, and random short fiber composites of CPP/PLLA for cancellated bone.

因此，CPP/PLLA单向长纤维及单向短纤维复合材料的初始力学性能满足承重骨骨内固定材料的力学性能要求；CPP/PLLA随机短纤维复合材料的初始力学性能满足松质骨骨内固定材料的性能要求。

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.

植入材料后4周，实验组可见珊瑚羟基磷灰石表面有细胞生长，孔隙内有结缔组织长入；对照组仅见珊瑚羟基磷灰石表面有细胞生长。8周时珊瑚羟基磷灰石表面有新生骨形成，孔隙内和孔隙边缘可见骨样组织沉积和少量软骨样组织形成；对照组仅见少量纤维结缔组织长入。12周时珊瑚羟基磷灰石材料表面有较多成熟编织骨形成，部分区域可见髓腔样结构形成，并有血管长入；对照组仍未见新骨及骨样组织形成。

讨论 FSS对成骨细胞功能的影响骨骼按遗传基因的调控建设骨骼的雏形，并在骨的生长发育中根据所承受载荷的需要对自身不断地进行改建与重塑，以试图实现用最小的骨量达到最大的骨强度，这就是骨的功能适应性。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The method comes from October 2001 in December 2007, serious to 41 femur bone is short of the author the patient of caustic applied akin variant in art of hip joint overhaul bone of the coriaceous bone establish that prop up.

方法从2001年10月至2007年12月，笔者对41例股骨严重骨缺损的患者在髋关节翻修术中应用了同种异体皮质骨支撑植骨。

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.

本研究之目的在评估与工研院生医中心合作发展出可吸收性去乙醯几丁聚醣/胶原蛋白复合之组织导引再生膜片，并选择与可吸收性之BioMend Extend 及Peri-Aid 胶原蛋白膜片，和GORE-TEX OSSEOQUEST 合成高分子膜片，及不可吸收之GORE-TEX e-PTFE合成高分子膜片，等其他四种市售商品材料共同对照评估，应用8只年龄为12个月的雄性小猎犬，均分4组(分别为7天、14天、28天、3个月)，为动物活体评估模式，在实验犬之左、右下颚第一、二小臼齿及大臼齿的颊侧区制造骨缺损后，分别植入组织导引再生膜片，依实验设定时间将小猎犬牺牲，取下缺损区骨头，以光学显微镜观察量测其牙垩质再生高度与齿槽骨再生高度之变化，以探讨其组织再生模式及评估新膜片在临床应用之适用性。
