Mechanics of the antebrachial interosseous membrane: Response to shearing forces

Structural properties of reconstruction constructs for the interosseous ligament of the forearm

“…Their results are not comparable directly with those obtained in our study because we applied load along the direction of IOL fibers to isolated IOL constructs. In general the stiffness and strength measurements for the intact interosseous membrane reported by McGinley et al 16 and Wallace et al were higher than those we obtained for the intact IOL, likely because of the difference in loading mode and the fact that accessory bands would contribute additional stiffness and strength.…”

“…20 Other studies have examined the tensile properties of the IOL. McGinley et al 16 reported on ultimate load and modulus of the entire interosseous membrane (IOL and accessory bands) loaded in a shearing mode with force applied along the axis of the radius and ulna oblique to the direction of IOL fibers. Wallace et al reported on stiffness and ultimate load for a similar testing configuration.…”

Form and function of the oblique cord (chorda obliqua) in anthropoid primates

“…Because of its fiber orientation, the oblique cord is not likely to be involved in transferring force from the radius to the ulna during axial loading activities, contrary to reports of the interosseous membrane (Morris 1879;Schneiderman et al 1993;Birkbeck et al 1997;Skahen et al 1997;Markolf et al 1998;Pfaeffle et al 1999;McGinley et al 2001;Shepard et al 2001;Kaufmann et al 2002;but see Halls and Travill 1964). As the forearm is compressed and the radius is shifted proximally against the capitulum, the fibers of the interosseous membrane, which run from the radius proximally to the ulna distally, become taut and the load is shifted from the radius to the ulna through the membrane.…”

Oblique cord (chorda obliqua) of the forearm and muscle-associated fibrous tissues at and around the elbow joint: a study of human foetal specimens

“…The interosseous membrane of the forearm is most taut at the neutral position of the hand [5,18,28] and it plays a role in load transfer from the radius to the ulna during axial loading activities [15,25,27]. In contrast, because the fibre direction is at a right angle to the fibres in the interosseous membrane, the oblique cord is most taut during supination and is unlikely to play a role in axial load transfer from the radius to the ulna.…”
