OBJECTIVE
To demonstrate the anatomy of the radial and ulnar bursae of the wrist using MR and US images.
DESIGN
Ultrasonographic-guided tenography of the tendon sheath of flexor pollicis longus (FPL) and the common tendon sheath of the flexor digitorum of the fifth digit (FD5) of ten cadaveric hands was performed, followed by magnetic resonance imaging and gross anatomic correlation. Patterns of communication were observed between these tendon sheaths and the radial and ulnar bursae of the wrist.
RESULTS
The tendon sheath of the FPL communicated with the radial bursa in 100% (10/10) of cases, and the tendon sheath of the FD5 communicated with the ulnar bursa in 80% (8/10). Communication of the radial and ulnar bursae was evident in 100% (10/10), and presented an "hourglass" configuration in the longitudinal plane.
CONCLUSIONS
The ulnar and radial bursae often communicate. The radial bursa communicates with the FPL tendon sheath, and the ulnar bursa may communicate with the FD5 tendon sheath.
目的
利用磁共振成像（MR）和超声（US）图像展示腕部桡侧和尺侧滑液囊的解剖结构。
设计
对十具尸体手部的拇长屈肌腱鞘（FPL）和小指屈肌腱总腱鞘（FD5）进行超声引导下腱鞘造影，随后进行磁共振成像及大体解剖对比。观察这些腱鞘与腕部桡侧和尺侧滑液囊之间的连通模式。
结果
拇长屈肌腱鞘与桡侧滑液囊的连通率为100%（10/10），小指屈肌腱总腱鞘与尺侧滑液囊的连通率为80%（8/10）。桡侧和尺侧滑液囊的连通率为100%（10/10），在纵切面呈“沙漏”形。
结论
尺侧和桡侧滑液囊常相通。桡侧滑液囊与拇长屈肌腱鞘相通，尺侧滑液囊可能与小指屈肌腱总腱鞘相通。
