Radiographically, endosteal and periosteal thickening of the diaphyses of long bones (Figs.
Radiologically, the hallmark of the disorder is bilateral, symmetrical cortical thickening of the diaphyses of the long bones occuring on both the periosteal and endosteal sides of the diaphyses.
The diaphyses of major long bones usually are affected.
Compression plate fixation of acute fractures of the diaphyses of radius and ulna.
(1) The diaphyses of the femur, tibia, and humerus are also common sites of primary tumor involvement.
Imperfect treatment of fractures of the radius and ulna diaphyses leads to a loss of motion as well as muscle imbalance and poor hand function.
