问题 下列临床表现中与诊断肩关节前脱位无关的是
选项 A.患肢轻度外展 B.患肢短缩畸形 C.肱骨头异位,三角肌塌陷 D.Dugas征(+) E.X线检查(+)
答案 B
解析 :肩关节前脱位典型体征和症状为:方肩畸形,触诊肩峰下空虚,常可在喙突下、腋窝部位触到脱位的肱骨头,Dugas征阳性,X线检查有助于诊断。患肢短缩畸形为肱骨骨折的体征,与肩关节前脱位无关,故答案为B。

错误信息

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
