The dorsal retinaculum of the wrist consists of two layers: the supratendinous and the infratendinous. The infratendinous layer is limited to an area deep to the ulnar three compartments. There are six compartments for the tendons dorsal to the wrist separated by six longitudinal vertical septa. Each septum originates from the supratendinous retinaculum and inserts onto the radius. The sixth compartment for the extensor carpi ulnaris is complex. The tendon of the extensor carpi ulnaris is enclosed in an independent fibrous tunnel formed by the supratendinous retinaculum superiorly, the infratendinous retinaculum inferiorly, the sixth septum laterally, and the ulnar insertion of the retinaculum reinforced by longitudinal fibers called the "linea jugata" medially. Our findings support the concept of an adaptable dynamic collateral ligament system rather than the traditional radial and ulnar collateral ligaments.
腱上和腱下。腱下层局限于尺侧三个腱鞘深部的区域。腕背侧有六个腱鞘，由六个纵向垂直间隔隔开。每个间隔起自腱上支持带并附着于桡骨。尺侧腕伸肌所在的第六腱鞘结构复杂。尺侧腕伸肌腱被包裹在一个独立的纤维隧道内，该隧道由上方的腱上支持带、下方的腱下支持带、外侧的第六间隔以及内侧由纵向纤维加强的支持带尺侧附着部（称为“jugata线”）构成。我们的研究结果支持适应性动态侧副韧带系统的概念，而非传统的桡侧和尺侧副韧带概念。
