在这块骨骼后面，桡骨——下臂与手carpometacarpus的联接部分——要比尺骨厚的多(与桡骨类似但相对较细的部分)。
Behind this bone, the radius - a lower arm bone in line with the carpometacarpus - was unusually thick compared to the relatively slender companion bone, the ulna.
手臂桡骨和尺骨的连接关节是一个枢轴关节。
The articulation of the radius and ulna in the arm is a pivot joint.
方法采用三棱钉张力带固定尺骨、钢板固定桡骨治疗30例尺桡骨骨折，尺桡骨钛合金钢板内固定治疗25例，观察两组病例的手术时间、尺骨骨膜剥离长度和骨折愈合时间。
Methods 30 patients were treated with ulna by triangular nail and tension band and radius by plate fixation. 25 patients were treated with both ulna and radius by titanium plate fixation.
灵长类的上臂有一根长骨（肱骨），前臂有两根细骨（尺骨和桡骨）。
Primate arms have one long bone, the humerus, in the upper arm above the elbow, and two thinner bones, the radius and ulna, in the forearm.
它能够支持并稳定尺骨末端的远端桡骨，增加了重复功能和舒适度，这与以前使用的治疗方法不同。
It supports and stabilizes the distal radius at the end of the ulna and adds reproducible function and comfort, unlike previously available treatments.
分析尺骨冠突骨折及合并桡骨小头粉碎骨折时肘关节的稳定性。
To determine the elbow joint stability in the coronoid process fracture and the coronoid process fracture merging radial head comminuted fracture by a mechanical experimental analysis.
结论：前臂完全旋后时，桡骨向远侧、背侧移位，尺骨头靠在尺骨切迹的掌侧面。
Conclusion: While the forearm in complete supination, the radius shifts to the dorsal and distal side, and the capitulum ulnae is at the volar side of the notch ulnae.
术中应该解剖复位尺骨骨折和桡骨头脱位，在随访中应该关注尺骨畸形和桡骨头半脱位或者脱位的问题。
The ulnar fracture and radial head dislocation should be anatomical reduced. And the ulnar should be concerned about deformity and radial head about subluxation or dislocation during follow-up.
结论前臂肌间隔是环状韧带重建的理想方法，适合治疗不伴尺骨畸形和桡骨过度生长的单纯儿童桡骨小头陈旧性脱位。
Conclusion Annular ligament reconstruction with forearm intermuscular septum can lead to satisfactory results for chronic radial head dislocation in children.
