Follow-up radiographs after fracture union at that time showed no evidence of disease (Fig. 1).
AP and lateral radiographs of the left forearm showing 6.5 cm long lesion in the region of the distal syndesmosis between the radius and ulna.

The lesion resulted in pressure erosions upon the distal radius and ulna, causing a slight splaying of the bones (Fig. 2).  
Triple-phase bone scan revealing moderately increased radiotracer uptake in the distal shaft of the left radius and left ulna, as well as in the distal physis of the left radius.

A triple-phase bone scan was administered and demonstrated increased uptake in the distal shaft of the left radius and left ulna, as well as in the distal physis of the left radius (Fig. 3).
(A and B) T1 MRI showing mass iso-intense to muscle. (C) T2 MRI axial view with overall increased signal intensity, but with a central area of decreased signal.

Dorsal plate fixation was used to stabilize the allograft, which extended from the native proximal radius to the proximal carpal row, effectively creating a single-bone forearm (Fig. 5).
