The extensor tendon compartments of the wrist are six tunnels which transmit the long extensor tendons from the forearm into the hand.
腕关节的伸肌腱隔室是六个通道，将前臂的长伸肌腱输送到手部。
They are located on the posterior aspect of the wrist. Each tunnel is lined internally by a synovial sheath and separated from one another by fibrous septa.
它们位于腕关节的背部。每个隧道内部衬有滑膜鞘，由纤维隔相互隔开。
In this article, we shall look at the anatomy of the extensor compartments of the wrist their location, contents and clinical correlations.
在这篇文章中，我们将看看手腕伸肌隔室的解剖学，它们的位置，内容和临床相关性。
Compartment 1
The first extensor compartment is located on the lateral (radial) aspect of the wrist. It transmits two tendons:
Extensor pollicis brevis
Abductor pollicis longus
These tendons form the lateral border of the anatomical snuffbox.
间室1
第一个伸肌室位于手腕的桡外侧。它传递两条肌腱:
拇短伸肌
拇长展肌
这些肌腱形成了鼻烟壶的外侧边界。
Compartment 2
The second extensor compartment contains the tendons of the extensor carpi radialis longus and extensor carpi radialis brevis.
This compartment is separated from compartment 3 by Lister’s tubercle – a bony prominence of the distal aspect of the radius.
间室2
第二个伸肌室包含桡侧腕长伸肌腱和桡侧腕短伸肌腱。
这个腔室与腔室3被Lister结节(桡骨远端的骨突出)隔开。
Compartment 3
Compartment three conducts the extensor pollicis longus tendon – this forms the medial border of the anatomical snuffbox.
间室3
第三腔室包括拇长伸肌腱-这形成了解剖鼻烟壶的内侧边界。
Compartment 4
The 4th extensor compartment of the wrist transmits the tendons of the extensor digitorum and extensor indicis.
间室4
手腕的第4伸肌室包含示指伸肌和指伸肌的肌腱。
Compartment 5
Compartment five contains the extensor digiti minimi tendon, which travels into the little finger.
间室5
第五腔室包含小指伸肌腱，它进入小指。
Compartment 6
The sixth compartment is the located on the medial (ulnar) aspect of the wrist. It conducts the tendon of the extensor carpi ulnaris.
间室6
第六腔室位于手腕的内侧(尺侧)。它包括尺侧腕伸肌肌腱。
