Fig. 4-31 cont’d C, Postoperative radiographs 10 weeks after initial
surgical repair show healed fractures, and the fracture lines are not visible.
The bony callus is smooth and contains a normal trabecular pattern.
The margins of the ulnar fragments are smooth and a dense
cortical shadow is forming. There is a small amount of bony callus
around the proximal end of the bone plate. The bone plate and screws
are intact. D, The bone plate has been removed and the healing of the
fracture is apparent. There is some loss of bone density beneath the
bone plate; however, this is minimal. The radius has healed without
deformation and with minimal callus due to the rigid immobilization
provided by the bone plate. The ulna has also healed but with a larger
amount of callus. The changes in the radius represent the usual pattern
of bone healing associated with rigid fixation. Diagnosis: Healed fracture.
