The biomechanical function of the interosseous membrane of the forearm was examined in 12 fresh cadaver forearms. The strain in the central band of the interosseous membrane was found to be greatest in full pronation and was significantly increased with excision of the radial head. The proximal/distal location of the lunate fossa of the radius with respect to the ulna was measured and was found to be most distal in supination and most proximal in pronation, in both the intact specimen and after excision of the radial head. Serial sectioning of the interosseous membrane and the triangular fibrocartilage complex (TFCC) demonstrated that both the central band and the TFCC are important to the axial stability of the forearm. Reconstruction of the central band, using a graft based upon the flexor carpi radialis, was performed in all 12 specimens after the interosseous membrane and the TFCC were sectioned. It was successful in preventing complete migration of the radius to the capitellum, but it was not capable of completely restoring the longitudinal stability of the forearm. Central band reconstruction as described here has not been performed in the clinical setting and is not advocated for clinical application at this time.
在12个新鲜尸体前臂中检查了前臂骨间膜的生物力学功能。发现骨间膜中央束的应变在完全旋前时最大，并且随着桡骨头切除而显著增加。测量了桡骨月骨窝相对于尺骨的近端/远端位置，发现在完整标本和桡骨头切除后，该位置在旋后时最靠远端，在旋前时最靠近端。对骨间膜和三角纤维软骨复合体（TFCC）进行连续切片显示，中央束和TFCC对前臂的轴向稳定性均很重要。在切断骨间膜和TFCC后，对所有12个标本进行了基于桡侧腕屈肌的移植物重建中央束。它成功地防止了桡骨向小 capitellum 完全移位，但不能完全恢复前臂的纵向稳定性。本文所述的中央束重建尚未在临床环境中进行，目前也不提倡临床应用。
