Abstract

OBJECTIVES

To introduce a ligament in the posterior distal extent of the forearm interosseous membrane (IOM).

METHODS

Ten cadavers were dissected in which the ligament was consistently present extending obliquely from the distal radius metaphysis to the distal radioulnar joint capsule. The ligament was also explored in a patient during posterior interosseous nerve (PIN) excision.

RESULTS

The posterior oblique ligament (POL) is found consistently in all cadavers via a dorsal approach.

CONCLUSION

This discovery highlights the complexity of forearm ligamentous structures and their role in the proximal, middle, and distal radio-ulnar stabilization.

摘要

目的

介绍前臂骨间膜（IOM）远端后方的一条韧带。

方法

解剖了10具尸体，其中该韧带始终存在，从桡骨远端干骺端斜向延伸至桡尺远侧关节囊。在1例患者进行骨间后神经（PIN）切除时也对该韧带进行了探查。

结果

通过背侧入路在所有尸体中均能始终发现后斜韧带（POL）。

结论

这一发现凸显了前臂韧带结构的复杂性及其在桡尺近端、中部和远端稳定中的作用。
