58 關於傷科疾患，下列敘述何者正確？
(A)4 歲小兒，上肢受牽拉後疼痛，致肘關節無法屈伸，診為小兒橈骨頭半脫位，X 光檢查常見橈骨頭 向上移位畸形
(B)病人臀中肌損傷，以患肢進行 Trendelenburg 氏測驗時，常見骨盆傾斜向患側
(C)顳顎關節脫位，常因過度張口、大笑引起，《傷科大成》及《傷科補要》皆認為「氣虛」是其中 病因
(D)肩關節脫位，出現關節盂空虛的症狀，常在肩後方觸診到突出的肱骨頭，以肘關節屈曲，手臂貼 及胸壁，手指可觸摸到對側肩部 

病人臀中肌損傷，以患肢進行 Trendelenburg 氏測驗時，

常見骨盆傾斜向健側吧，應改成軀幹向患側傾斜

The Trendelenburg sign is most apparent during the gait cycle (see Image. Trendelenburg Gait). The pelvis rises ipsilaterally when the leg supports the body's weight on the lesioned side. This presentation is more accurately dipping the pelvis towards the contralateral side. Because the lesioned abductors cannot maintain the pelvis in a level plane, the patient falls towards the good side and simultaneously leans the torso towards the lesioned side to maintain balance. This type of gait is known as the Trendelenburg gait.
