Longitudinal stability of the forearm is mainly provided by three structures: the radiocapitellar contact, which acts as the primary stabilizer, the central band of the interosseous ligamentous complex (IOLC) and the intact triangular fibrocartilage complex (TFCC). In an Essex-Lopresti lesion the forearm becomes fully destabilized, since all of these three components are injured. Fixation or replacement of the radial head with a metallic prosthesis along with repair of the TFCC and stabilization of the distal radioulnar joint (DRUJ) are well-established treatment goals. However the reconstruction of the central band of the IOLC remains to some extent controversial. The authors believe that the reconstruction of the central band, particularly in active patients, is crucial in order to restore normal load distribution through the forearm, thus ensuring both transverse and longitudinal stability. In this article, we present a case with an Essex-Lopresti lesion, which was effectively treated acutely with restoration of all three components of the injury (radial head prosthesis, DRUJ repair and reconstruction of the central band of the IOLC). A novel technique by rerouting the brachioradialis tendon is described in detail.
桡骨头关节面接触,作为主要稳定器;骨间韧带复合体(IOLC)的中央束;以及完整的三角纤维软骨复合体(TFCC)。在Essex-Lopresti损伤中,由于这三个组成部分均受损,前臂会完全失去稳定性。使用金属假体固定或置换桡骨头,同时修复TFCC并稳定下尺桡关节(DRUJ),是公认的治疗目标。然而,IOLC中央束的重建在一定程度上仍存在争议。作者认为,中央束的重建,尤其是对于活跃的患者,对于恢复前臂的正常负荷分布至关重要,从而确保横向和纵向稳定性。在本文中,我们介绍了一例Essex-Lopresti损伤病例,通过恢复损伤的所有三个组成部分(桡骨头假体、DRUJ修复和IOLC中央束重建)进行了有效治疗。详细描述了一种通过重新路由肱桡肌腱的新技术。
