Palpation of bony landmarks on distal Radius and Ulna
0:00
這是一段視頻示範，展示如何觸診橈骨和尺骨的骨性標誌。
This is a video demo showing how to palpate the bony landmarks on the distal radius and ulna.

示範是在右臂上。要觸診橈骨莖突，沿著橈骨的軸向外側觸診。
The demo is on right arm. To palpate the radial styloid process, palpate along the shaft of radius distally onto the lateral side of the radius.

在橈骨的外側遠端有一個骨性突起。它是橈骨最遠端的部分。
There is a bony projection distally on the lateral aspect of radius. It is the most distal part of radius.
0:23
那是橈骨莖突，它是肱橈肌的附著點。
That's the radial styloid process, which is the attachment site for the brachioradialis.
0:30
從橈骨莖突開始，移動到橈骨的後側以定位李斯特結節。
From the radial styloid process, move on to the posterior aspect of radius to locate the Lister's tubercle.
0:38
在橈骨的遠端感覺到一條骨性脊。那是李斯特結節，也稱為背側結節。
Feel for a bony ridge on the distal end of radius. That's Lister's tubercle aka dorsal tubercle.
0:44
這位於拇長伸肌腱和短橈側伸肌腱之間。
This is located between the extensor pollicis longus tendon and the extensor carpi radialis brevis tendon.
0:53
現在我們來觸診尺骨的頭部。沿著尺骨的軸向遠端觸診。
Let's palpate the head of ulna. Palpate along the shaft of ulna distally.
0:58
尺骨的遠端是頭部。或者你可以先觸診橈骨的李斯特結節，然後將手指滑向尺骨，距離約一英寸。
The distal end of ulna is the head. Or you can palpate Lister's tubercle on the distal radius first and slide your finger toward ulna about an inch away from it.
1:08
現在你在尺骨的頭部。從頭部開始，移動到尺骨遠端的後內側以觸診尺骨莖突。
Now you are on the head of ulna. From the head, move on to the posteromedial aspect of the distal ulna to palpate the ulnar styloid process.
1:17
它是手腕尺側韌帶關節盤的附著側。
It is the attachment side of the articular disc in the ulnar collateral ligament at wrist.
1:23
現在觸診橈骨和尺骨的兩個莖突，並比較哪一個延伸得更遠。
Now palpate both styloid processes on radius and ulna and compare which one extends farther distally.
1:30
如果你感覺到橈骨莖突更遠，你是對的。
If you feel the radial styloid process farther distal, you are correct.

這就是觸診橈骨和尺骨遠端骨性標誌的內容。謝謝觀看。
This is it for the palpation of the bony landmarks on the distal radius and ulna. Thank you for watching.
