Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.

结果 7例齿状突骨折中，X线显示4例，CT显示5例，CT重建确诊7例，且清楚显示骨折移位情况；6例X线、CT显示寰枢椎左右间隙不对称，通过CT重建排除寰枢关节半脱位；寰枢外侧关节脱位1例，CT重建可清楚显示，而X线片和CT平扫均未能显示；寰枢椎畸形3例，分别为齿状突、后弓缺如1例，齿状突发育不良2例，CT重建均能清楚显示，而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。

Objective To study the anatomy of calcaneous sustentaculum tail and paries lateralis, and confirm the safe fixation pathway for sustentaculum tall and paries lateraiis.

Cases with bone graft fusion were Resected lateral part of lesion vertebral lamina and process;2 cases were treated with contralateral interanticular process and vertebral lamina bone graft fusion; 2 cases with intravertebral fusion were treated by laminectomy and arthrectomy of one side by posterior route and USS implantating; Others cases were routine internal fixation.

行植骨融合术2 例，切除患侧椎板外半和椎间相应关节突；行对侧椎板关节突间植骨融合2例，行后路半椎板和一侧小关节切除USS 植入，椎间融合2例，余采用常规手术内固定。

Results In 50 cases of fracture of nasal bone, fracture of the frontal process of maxillary bone was found in 43 cases, fracture of lacrimal bone in 29 cases and fracture of orbital walls in 24 cases. Separation of nasomaxillary suture was found in 36 cases, nasofrontal suture in 14 cases, lacrimo-maxillary suture in 18 cases and internasal suture in 9 cases.

结果 50例鼻区复合骨折中均有鼻骨骨折，伴发上颌骨额突骨折43例，泪骨骨折29例，额骨鼻部骨折16例，眶壁骨折24例；伴发鼻颌缝分离错位36例，鼻额缝分离14例，泪颌缝分离18例，鼻骨间缝分离9例，额颌缝分离10例。

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。

The authors found that the prealence of protrusio increased to approxi- mately 35.9% by the age of twenty years and then it plateaued; howeer, its presence did not correlate with osteoarthritic changes as measured with the Iowa hip score in patients more than forty years of age.

作者发现髋臼前突的发病率在20岁时增加到35.9%然后进入平台期，但其表现与骨关节炎改变并不成比例（IOWA髋指数，年龄大于40岁）；对有症状的患者来说，髋关节前突与髋部疼痛之间呈正相关关系，关节间隙宽度与髋前突间呈负相关关系，提示髋关节前突的力学因素对关节退变有一定作用，但可能不是主要因素。

Objective To report the clinical outcome of the transposition of the radial styloid bone flap pedicled on the recurrent branch of the radial artery in the treatment of scaphoid nonunion.

目的 总结以桡动脉茎突返支为蒂的桡骨茎突骨瓣移位治疗舟骨骨折不愈合的临床效果。

Objective To study the anatomy of calcaneous sustentaculum tali and panes lateralis, and confirm the safe fixation pathway for sustentaculum tali and panes lateralis.

目的 研究跟骨载距突与其外侧壁的解剖关系，获得通过跟骨外侧壁固定载距突螺钉的安全通道。

Careful treatment can decrease the complication rate. 3. Three-dimensional finite element model analysis showed that zygomaticoalveolar crest is the major site sustaining stress, which indicated that the fixation of zygomaticoalveolar crest should be strengthened, if there is some space between zygomaticoalveolar crest and fibula bone, free bone graft can fill the space to rebuild the bony zygomatic process support.

游离腓骨复合组织瓣上颌骨重建的三维有限元分析表明，颧牙槽嵴部位是腓骨瓣上颌骨重建后咀嚼压力的主要受力部位，提示腓骨瓣上颌骨重建时要加强颧牙槽嵴的固定；当上颌骨切除后腓骨与颧牙槽嵴存在间隙时，应尽量采取游离骨块移植，充填间隙，重建骨性颧突支柱。

An electrophysiologic study on sEMG of trunk rotaory muscles in stroke patients;2. The characteristics of the skeletons of the trunk in bactrian camel are the following.

双峰驼躯干骨的特征如下：寰椎的背腹侧嵴都不明显，有外侧孔、翼孔、横突孔；枢椎较长；第3，4和5颈椎的横突前支比后支长；第6颈椎有不太典型的横突中支；第7颈椎横突不分支。
