This case report calls into question the need for possible acute interosseous membrane
INTRODUCTION Normal function of forearm requires intact skeletal structures, interosseous membrane
, proximal and distal radioulnar joints and neurovascular structures to put hand more effectively in space.
Multiple soft tissue stabilization procedures have been described ranging from weaving a slip of extensor carpi ulnaris (ECU) tendon through the distal ulna and interosseous membrane
, to creating a sling around the distal ulna with ECU and FCU tendon, to placing an Achilles allograft as a soft tissue interposition between the radius and ulna.
On the dorsum of the foot, we observed an hypertrophied perforating fibular artery (HPFA) traversing the interosseous membrane
to enter the extensor compartment.
The PIN descended deep to the extensor pollicis longus (EPL) muscle on the posterior surface of the interosseous membrane
sending two to three short nerve branches to supply the EPB and El muscles (Figure 3C).
The interosseous membrane
becomes increasingly relaxed with further supination or pronation.
The anterior interosseous artery courses down the forearm and pierces the interosseous membrane
to anastomose with the posterior interosseous and joins the dorsal carpal network.
In such cases, successful outcomes have been reported (Turner & Cooper, 1971; Janda et al.; Bliss & Menelaus, 1986; Georgiadis & Aronson; Fernandez-Feliberti et al.; Vogt) where the tibialis anterior muscle is surgically transposed by passing it posteriorly through the interosseous membrane
and attaching it to the calcaneus.
(3,4,5,6) [Figure 1 and 2] The latter structure is the primary restrictor of diastasis of this complex, and blends proximally with the interosseous membrane
. (3,4,5,6) Yet while the anatomical complexity is minimal, the diagnostic efficacy with respect to this condition appears to be suspect, as evidenced by the large discrepancy of incident data.
Ossification of the interosseous membrane
(OIM) of the leg may exhibit some features similar to those of myositis ossificans.
After giving muscular branches in the flexor compartment it is running deep and gave a branch which is piercing the interosseous membrane
. So, in the present case the muscles of forearm are being supplied by the common interosseous artery instead of ulnar artery.
The ankle syndesmosis is made up of four ligaments, including the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), the transverse tibiofibular ligament (TTFL), and the interosseous ligament (IOL), a distal extension of the interosseous membrane
