Methed:The light microscops,transmission and scanning electronic microscops were performed on cartilage of adjacent joint facet cephalad to multi segments and short segmental spinal internal fixation in 10 goats at 6 months postoperatively.

设计山羊长节段及短节段脊柱内固定的动物模型，对固定6 个月后近头侧两个邻近关节突关节进行光镜、扫描电镜及透射电镜的观察。

Results The wire direction was 14~37° lateral and 18~39° cephalad for C(subscript 3~7) lateral mass when the K-wires drilled starting at the point 1 mm medial to the center of the lateral mass and exited at the juncture between the transverse process and the facet. The tips of K-wires did not injure the nerve roots and vertebral arteries. The depth of these wires in the lateral mass ranged from 9.4 to 14.8 mm.

结果 以C(下标 3~7)侧块背面中心内侧1mm处为入针点，克氏针向头侧成角18~39°、向外侧成角为14~37°，针尖可自横突与侧块相交处后方穿出，该处与神经根和椎动脉均隔以横突后结节。C(下标 3~7)侧块内进针深度为9.4~14.8mm。

METHODS: From June 2007 to March 2009, 8 patients with terrible triad of the elbow were treated. The fracture of the radial head was classified according to the system of Mason, with typeⅠ in 1 patients, type Ⅱ in 6 and type Ⅲ in 1; fracture of the coronoid process was classified according to the system of Regan and Morrey, with type Ⅰin 2 patients, type Ⅱ in 5, and type Ⅲ in 1. The hollow lag screws and Herbert screws were used to fixe coronoid process and radial head fractures, and repair Annular ligament. Lateral collateral ligament was repaired in 1 case. All injured extremities were treated with a posterior plaster splint with the elbow joint held in 90° of flexion and the forearm in neutral rotation for 2-3 weeks followed by elbow rehabilitation training.

于2007-06/2009-03共收治肘关节恐怖三联征患者8例，其中尺骨冠突骨折按 Regan-Morrey法分类：Ⅰ型2例，Ⅱ型5例，Ⅲ型1例；桡骨头骨折按Mason法分类：Ⅰ型1例，Ⅱ型6例，Ⅲ型1例。8例患者均采取了内固定治疗，采用中空拉力螺钉或Herbert螺钉固定冠突和桡骨头骨折，修补环状韧带，1例缝合修复肘外侧副韧带，术后屈肘90°旋前中立位，以塑形良好的高分子管型石膏固定两三周后开始屈伸和旋转康复训练。

The principles of the operative technique are to (1) restore coronoid stability throughfracture fixation (type-II or III fractures7) or through anterior capsular repair (a type-I fracture),(2) restore radial head stability through fracture fixation or replacement with a metal prosthesis,(3) restore lateral stability through repair of the lateral collateral ligament complex and associated so-called secondary constraints such as the common extensor origin and/or the posterolateral capsule,(4) repair the medial collateral ligament in patients with residual posterior instability, and (5) apply a hinged external fixator when conventional repair does not establish sufficient joint stability to allow early motion.

外科手术的原则是：①通过骨折固定(2型骨折或3型骨折)或者经前方关节囊修复(1型骨折)恢复冠状突的稳定。②通过骨折固定或假体置换恢复桡骨头的稳定性③通过修复侧副韧带以及相关的所谓的次要限制如伸肌群起点和后外侧关节囊。④残余的后侧不稳，修复内侧副韧带⑤当传统的修复方法不能建立有效的关节稳定以便允许早期活动时，可以应用外固定器。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle.

The conventional cephalometric analysis chosen SNA, SNB, ANB, NA-PA etc to reflect the protrusion or retrusion of maxillary and Mandible, but they can't reflect this extent quantitatively. The Delaire cephalometric analysis can analyze the protrusion or retrusion of maxillary and Mandible quantitatively through Me-F1,Me-Met,Np-F1 etc. This method combine with conventional methods can evaluate accurately, quantitatively and directly.

传统头影测量分析选用SNA、SNB、ANB、NA-PA等角度来反映上下颌的前突或后缩，并不能定量的反映上下颌前突或后缩的程度；而Delaire头影测量分析中Me-F1，Me-Met，Np-F1可定量分析上下颌前突或后缩程度，结合传统的角度测量将利于直观、定量的评价，也利于准确的诊断设计。

Results After induced for 8 h, the protoscoleces shrank in dexamethasone group and dexamethasone＋ATP group, the rosellum was invaginated. Compared with the control, the calcareous corpuscles in the protoscolex significantly reduced and blurred in the two groups. The morphological changes in protoscolex of dexamethasone＋ATP group was more obvious than that of dexamethasone group.

结果 药物诱导8 h后观察，与对照组相比，地塞米松组和地塞米松+ATP组的原头节均出现团缩、顶突内凹和体积缩小，钙颗粒明显减少且模糊不清，未见原头节活动，其中地塞米松+ATP组原头节的形态改变更明显，故选择该组作为实验组，与空白对照组进行后续试验。
