后屈

If parallel rays are not focused on the retina of a static eye , the eye is ametropic.

3如果平行光线入眼后不能聚焦到静态眼的视网膜上，则称该眼为屈光不正。

Results: In the primary arthroplasty group, the aerage flexion improed from 116° to 135°; aerage extension, from –40° to –33°; aerage pronation, from 60° to 81°; and aerage supination, from 60° to 69°.

结果：在初次关节成形术的患者中，病肘的平均屈曲度从116°增加到了135°，平均伸展度从－40°改进到了－33°，平均旋前从60°增加到了81°，平均旋后从60 °增加到了69°。

Objective To investigate the foot function reconstruction after replantation of amputated leg.

目的 探讨小腿中段离断再植后足跖屈背伸功能重建的方法。

These include fluid within the tendon sheath, fluid withinthe medial or lateral bursae, sinus tarsi syndrome, periostitisat the insertion of the flexor retinaculum on the tibia, hindfootvalgus, subtalar and talonavicular malalignment, and accessorynavicular bone.

这些包括腱鞘内、内外侧滑膜内水分滞留，跗骨窦综合症、屈肌支持带的胫骨侧附着处骨膜炎、后足外翻、距下关节和距舟关节排列不整及副舟骨。

Methods:Retinoscopy was performed on 17 eyes of 17 patients with silicone oil injection in which the retina is in place.Pre-and postoperative refractive states were compared.

对17例已行玻璃体切割硅油填充手术后视网膜基本复位的患者进行检影，对比患者术前术后不同的屈光状态并进行分析。

The mean change in spherical equivelent refraction during the follow-up interval was -0.42 D (SD: 0.68D) in right eyes.

睫状肌麻痹后的电脑自动验光结果显示：在28个月中右眼的平均屈光不正的进展是-0.42D（标准差0.68D）。

Supination, flexion and extension of wrist joint were generally normal, and the fracture was generally healed.

旋后功能及腕关节屈伸功能基本恢复正常，骨折全部愈合。

The stress of forearm pronation, neutral, supination was determinated in simulating elbow joint extension and 45° or 90° of flexion.

肱骨外髁在屈肘90°前臂旋后位时，水平方向的压应变最大，中立位次之，旋前位时其前方呈拉应变。
