屈曲

We tested the knees at flexion angles of 0, 15, 30, 60, and 90with the following applied loads: 10 Nm varus moment, and 5 Nm external and internal rotational torques.21,22 To calculate the force applied in varus rotation testing, we took the desired moment (10 N.m) and divided this by the distance from the joint line to the point of force application in meters.

我们检测了施加力量10N.m的内翻运动和5N.m的外旋和内旋运动，各种运动的膝关节屈曲角度分别为0°、15°、30°、60°和90°。为了在内翻旋转试验时计算施加力，我们采用期望力矩(10M.m)，并将这种力矩分为从关节线到施加力点数米远的距离。

The results indicate that the fixation methods for supracondylar fractureshould b that:(1) The fixation with the flexion angle of 9O°in the pronator position is adopted if the medial side presents displacement and the lateral periosteum is broken and the "hinge"of the medial periosteum remained unbroken.

表明肱骨髁上骨折的固定方法宜采用：①若内侧移位，外侧骨膜破裂，内侧骨膜"铰链"完整，则采用屈曲90°旋前位固定；②若外侧移位，内侧骨膜破裂，外侧骨膜"铰链"完整，则采用屈90°旋后位固定；③若内外侧骨膜完全破裂，不论是内侧移位，还是外侧移位，宜采用旋后位固定。
