Fig. 1-B The radial head is reduced, and the distal fragment is supinated.



Fig. 1-C A vascularized fascio-fat graft is inserted in a volar-to-dorsal direction between the separated radius and ulna.



Figs. 2-A through 2-D: Photographs illustrating the intraoperative procedure.



Fig. 2-B After separation of the synostosis and the synchondrosis, the radial head (arrow) is trimmed and a trapezoid-shaped wedge of bone is resected to reduce the dislocated radial head.



Fig. 2-C The radius is fixed with a four-hole titanium plate.



Fig. 2-D The vascularized fascio-fat graft is shown along with a segment of skin obtained from the ipsilateral arm.



Figs. 3-A through 3-F: Case 7.



Fig. 3-B Lateral roentgenogram showing the posterior dislocation of the radial head.



Fig. 3-C Computerized tomographic scan showing the synostosis of the radius and ulna and a thin intervening septum.



Figs. 3-D, 3-E, and 3-F: Roentgenograms and computerized tomographic scans made two years and six months postoperatively.
