(25) found that MRI had a 100% positive predictive value, with the interosseous membrane
best viewed on axial T2-weight images.
An assistant applies pressure on the interosseous membrane
(IOM) of the forearm, while the physician pushes posteriorly on the ulnar head and pronates the forearm.
 Circumtibial transfer should be reserved for patients with a calcified and unyielding interosseous membrane
; these are usually elderly with recurrent inflammation and infection in the foot.
The common interosseous artery is a short branch of the ulnar, passes back to the proximal border of the interosseous membrane
and divides into anterior and posterior interosseous arteries.

Excellent to good results were observed in those who were treated by open reduction of ulnar fracture by callus trimming with indirect reduction of radial head via interosseous membrane
Directly beneath the FCR tendon there was a bulky and longitudinally oriented muscle belly arising from the distal radius and having an oblique origin from the interosseous membrane
and the ulna distally (Figure 1).
The radial head may be considered as a multifunctional conjoint stabilizer of the elbow because it serves to check instability in three planes: the coronal plane as it works with the medial collateral ligament to prevent valgus instability; the saggital plane as it works mainly with the posterolateral ligamentous structures, the coronoid process and the medial ligaments to prevent posterior dislocation; and in the axial plane as it works with the interosseous membrane
to prevent the shaft of the radius riding up.
These include arthrosis of the elbow joint space, ossification of elbow ligaments (including the annular and collateral ligaments), disruption of the joint capsule leading to capsular fibrosis , soft tissue contracture, ectopic calcification of surrounding soft tissue structures (including myositis ossificans of the brachialis muscle), failure of fracture healing , and bone fragments that inadvertently remain in the interosseous membrane
The dissection stops anteriorly once the interosseous membrane
is reached and posteriorly once the aponeurosis separating the peronei from the posterior flexors was reached.
The joint capsule of the DRUJ and the interosseous membrane
(IOM) constitute the remaining static restraints.
The ATA was of a good caliber size at origin (about 2.6 mm in diameter), passes through the oval aperture in the proximal part of the interosseous membrane
to reach the extensor compartment where we observed the ATA supplying very prominent muscular branches to muscles in the anterior leg compartment (Fig.
This variant muscle originated from the posterior surface of the distal third of the shaft of the ulna, the adjacent interosseous membrane
, and from the internal surface of the antebrachial fascia occupying the interface of the superficial-deep forearm extensors (Figure IB).
The interosseous membrane
and the synostosis were then exposed and excised (Figure 3), and the flap was turned into the distal radioulnar space (Figures 4(a) and 4(b)).
