Control is better than that of A-P Gamma nail in both press and torsion property. It may be the main cause that A-P Gamma nail possesses unstability for the treatment of peritrochanteric fracture of femur.

A-P型Gamma钉在抗压和抗扭转强度方面明显低于对照组，其潜在的不稳定因素可能是Gamma钉治疗股骨粗隆周围部骨折所致的并发症直接原因。

Objective To study the complications and cuases of Gamma nail for the treatment of peritrochanteric fracture of femur by biomechanics test.Methods 16 fresh femoral specimens were divided into two groups, each consisting of eight specimens. One group was as control, another was as A-P Gamma nail.

目的 运用生物力学方法对股骨粗隆周围部带锁髓内钉治疗股骨粗隆周围部骨折所致的并发症及其原因进行研究，分析生物力学因素对Gamma钉所致的并发症的影响。

Prosthetic replacement, intramedullary nails, PMMA augmentation, and adjuvant radiation can be performed safely to patients with peritrochanteric metastasis for pain relief and recovery of ambulatory function.

结论采用假体置换、股骨交锁髓内钉或Recon钉固定、局部病灶刮除和骨水泥充填结合辅助治疗，可以安全地治疗股骨转子周围转移性肿瘤，缓解疼痛，恢复行走功能，对提高患者的生存质量有较大意义。

These three internal fixations of femoral peritrochanteric fracture were differ. For example, Gamma nail is less harmful, better clinical treatment, shorter in shape and stronger in anti-hip inversion. DHS, DCS have a better treatment and are stronger in anti-hip inversion but more harmful and excessive bleeding, and HCS, which is named Minimally Invasive Surgery, is the least harmful, less bleeding, suitable for old patients and the patients of tolerance of poor operation, but poor in anti-hip inversion.

3种不同方法内固定治疗转子间骨折具有各自的特点，Gamma钉具有手术损伤小及良好的临床疗效力臂短对抗髋内翻的能力强；滑动加压鹅头钉具有良好的临床疗效及相对坚强的抗内翻能力，但手术损伤相对较大，失血量较大；空心加压螺钉固定的手术损伤最小，属于微创手术方法，可经皮完成，手术出血少，适用于高龄及手术耐受性差的患者，但抗髋内翻的能力最差。

Methods Fourteen adult cadaver specimens of cervical spine（C3～C7）with intact structures including ligaments and perivertebral muscles were reserved and used.

随机取14具福尔马林浸泡的成人颈椎标本（C3～C7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。

Abstract］ Objective To explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.Methods Fourteen adult cadaver specimens of cervical spine（C3～C7）with intact structures including ligaments and perivertebral muscles were reserved and used.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性方法随机取14具福尔马林浸泡的成人颈椎标本（C3～C7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。

Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。

With TAPP, which became very popular among laparoscopists, the prosthesis is placed into the preperitoneal space following dissection, fixed with a stapling device or a spiral tacking device, and covered.

作为目前颇受医生喜欢的术式，TAPP的主要步骤是充分分离显露后，将补片覆盖在缺损和腹股沟区，利用钉合器或螺旋钉合器固定，将缺损补住，在完成手术后腹膜前组织保持原来解剖位置。

The entry angle decreased by 5°, so the entry point moved forward proximally by 5 mm.

进钉角度每减小5°，其进钉点就向近端移动约5mm。

Of the femoral fracture,there were 14 cases of fractures of shafts of femurs and 1 case of supracondylar fracture of femur;11 male, 4 female;7 left cases,8 right cases;1 case complicated with bending of bone plate and screw,6 cases with breakages of plate;1 case with bending of common intramedullary nail,2 cases with breakages of common intramedullary nails,1 case of screw and wire lock fixation complicated with pseudoarticulation formation,4 cases with nonunion of fracture.

方法］24例长骨骨折内固定手术失败应用有限切开交锁髓内钉治疗的长骨骨折翻修术病例中，股骨15例，其中股骨干骨折14例，股骨髁上骨折1例；男11例，女4例；左侧7例，右侧8例；接骨板螺丝钉折弯1例，断裂6例，普通髓内钉折弯1例，折断2例，螺钉并钢丝固定假关节形成1例，骨折不愈合4例。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
