A coincidental anterior interosseous nerve palsy after volar plate fixation of a distal radius fracture diagnosed by 3D-CT.

A case presented dysfunctional flexion of the thumb and index fingers after volar plate fixation for of distal radius fractures was diagnosed anterior interosseous nerve palsy and confirmed by 3D-CT. 3D-CT was useful to confirm the continuities of tendons, which excluded the most common complication of tendon ruptures after volar plate fixation. Also, it was superior to needle electromyography which is unreliable due to the accompanying damage of the pronator quadratus following volar plate fixation.
