However, 2 years after the operation, bony union was not achieved and elastic nail breakage had occurred, and he complained of pain and limitation of activity (Fig. 1).
Radiographs taken immediately after surgical fixation with a mandibular locking plate. The plate fits the deformed humeral shaft.

Since his humeral shaft was extremely narrow with severe deformity, we used a locking plate for the mandibular bone, which was contoured to fit the medial side of the humeral shaft (Fig. 2).
Bony union of the non-union was confirmed 4 years after the surgery. A new fracture line (white arrow) is found at the distal part of the non-union.

No implant failure or refracture of his humeral shaft had occurred 4 years later, but a new fracture line was found in radiographs of the distal part of the non-union (Fig. 3).
