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 load-displacement plot was measured and analyzed at elbow flexion of 90, 60, and 45° and under four conditions (intact elbow, type-I coronoid process fracture, type-I coronoid process fracture with AMCL deficient, and type-II coronoid process fractures with AMCL deficient).

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。

Aiming at the fracture in operation of damageable pump shaft used on locomotive, macroscopic and microscopic analysis of the pattern of fractured cross section in pump shaft is conducted and it is recognized that the fracture is typically caused by combined action of bending and torsion fatigue.

针对机车用水泵轴在使用中容易发生断裂的问题，对水泵轴断口的宏观和细观形貌进行了分析，认为断口为典型的弯扭复合疲劳断口。通过检测水泵轴上装配的齿轮，发现由于齿轮的加工误差过大，在轴的退刀槽根部造成了较大的附加拉应力，最终导致轴的断裂。因此及时消除齿轮的加工误差，同时提高安装精度，是防止此类断裂发生的关键
