Background: Diagnosis of damage to the interosseous
membrane of the forearm after trauma is difficult. Patients with
a proximal radial fracture and associated damage to the interosseous
membrane may have wrist pain in association with subluxation or dislocation
of the distal radioulnar joint. Accurate identification of injury
to the interosseous membrane may allow better planning of surgical
treatment.
Methods: T1 and T2-weighted magnetic resonance images that
were made in the axial, sagittal, and coronal planes were used to
evaluate the interosseous membrane in the forearms of cadavera,
volunteers, and patients. The images were evaluated subjectively
by two orthopaedic surgeons and a musculoskeletal radiologist.
Results: The interosseous membrane was most consistently visualized
on the axial images. Axial T2-weighted images showed the interosseous
membrane clearly. The addition of fat-suppression techniques allowed abnormalities
to be identified more accurately. Fast-spin-echo techniques were
used to obtain data quickly and accurately.
Conclusions: The intact and disrupted interosseous
membrane can be evaluated with use of magnetic resonance imaging.
Axial T2-weighted fast-spin-echo images with fat suppression in
the middle one-third of the forearm provide the most accurate information.
