“…2), both of which probably work as isometric collateral ligaments of the distal radioulnar joint (DRUJ) because the ulnar insertions of the DOB and the deep limbs of the radioulnar ligament almost coincide with the course of the axis of forearm rotation. 3 The TFCC is the primary soft-tissue DRUJ stabilizer, and the DIOM acts as a secondary stabilizer of the DRUJ when the dorsal and palmar radioulnar ligaments of the TFCC are cut. 4,5 In normal situations, the influence of the DIOM on DRUJ stability is relatively inconsequential.…”

The distal interosseous membrane (DIOM) of the forearm is on the distal side of the central band of the interosseous membrane, spanning the radius and ulna at the dorsal region of the pronator quadratus muscle. Recent anatomical studies have revealed that the thickness of the DIOM varies widely among specimens (0.5-2.6 mm), and an obvious thick fiber within the DIOM, called the distal oblique bundle (DOB), exists in 40% of specimens. 1,2 The DOB originates from the distal ulna 54 mm (on average; range, 50-57 mm) proximal to the ulnar head and runs distally to insert on the dorsal inferior rim of the sigmoid notch of the radius (►Fig. 1a,b). The DOB has an anatomical relationship with the triangular fibrocartilage complex (TFCC) (►Fig. 2), both of which probably work as isometric collateral ligaments of the distal radioulnar joint (DRUJ) because the ulnar insertions of the DOB and the deep limbs of the radioulnar ligament almost coincide with the course of the axis of forearm rotation. 3 The TFCC is the primary soft-tissue DRUJ stabilizer, and the DIOM acts as a secondary stabilizer of the DRUJ when the dorsal and palmar radioulnar ligaments of the TFCC are cut. 4,5 In normal situations, the influence of the DIOM on DRUJ stability is relatively inconsequential. However, after a TFCC injury, an ulnar head resection, or a Sauvé-Kapandji procedure, the DIOM has a more important role in the stability of the ulnar head or ulnar stump. The clinical relevance of the DIOM includes its stabilizing effect on the DRUJ in ulnar shortening procedures. Recent study has revealed that ulnar shortening with the osteotomy performed proximal to the attachment of the DIOM has a more favorable effect on stability of the DRUJ as compared to distal osteotomy, The distal radius with the distal interosseous membrane and TFCC viewed from the dorsoulnar side.

“…We created 3D computer bone models of the radius, ulna, and humerus from CT data using an original computer program based on the Visualization Toolkit (Kitware, Clifton Park, NY, USA). Volume-based registration [13,21,22,26] was performed semiautomatically to determine relative positions between volume images represented at different coordinates. We expressed transformation of the radius with respect to the ulna in helical axis parameters, which are defined as rotation about and translation along a unique axis [15,16].…”

“…The interosseous membrane is a complex of ligaments and membranes, each of which plays a different functional role [8,22,25,33]. Moritomo et al [22] investigated in vivo and 3D change in length of the interosseous membrane ligaments using a novel technique combined with normal anatomic data. They found the central band comprising the broadest and thickest fibers in the interosseous membrane [8,33], accessory band, and distal oblique bundle are almost isometric during forearm rotation, although there is slight laxity during pronation.…”

Background Forearm kinematics and interosseous membrane function in chronic radial head dislocations sustained in childhood are unknown. Several procedures have been performed to reduce the radial head on the basis of static preoperative assessment in only one forearm position, but clinical results are not always favorable. Questions/purposes We investigated the in vivo threedimensional (3D) kinematics and length changes of interosseous membrane ligaments during forearm rotation in chronic radial head dislocations using 3D CT registration techniques. Methods We examined 10 patients with chronic radial head dislocations (seven Type 1 and three Type 4 Monteggia lesions). To quantify kinematics, the axis of rotation (AOR) and radial head motion were investigated using computer bone models constructed from CT data placing the forearm in three positions. We also created six interosseous membrane ligaments and calculated their 3D lengths during forearm rotation.

The distal radioulnar joint (DRUJ) is a trichoid diarthrodial joint, allowing simultaneous pivoting and forearm rotation. The DRUJ along with the interosseous membrane (IOM) and the proximal radioulnar joint (PRUJ) make up the forearm joint. The ability to supinate and pronate has given the human species the uniqueness of being able to move the forearm and wrist without affecting the hand's ability to grasp objects. The complex motion of the forearm requires an intricate relationship of the osseous and soft tissue anatomy, balancing motion and stability.
