Fig. 1Preoperative left tibia anteroposterior (A) lateral (B) images show the nonunion, osteolytic bone defect and hardware the failure on the fibular fracture site.
Fig. 2Operative photos (A-D) show the broken plate and extensive gray-black colored tissue around the plate, and clean bony tissue after the removal of the plate and gray-black colored tissue.
Fig. 3Postoperative left tibia anteroposterior (A) lateral (B) images show the internal fixation with rush pin and autogenous bone graft for bone defect and nonunion site.
Fig. 4Histologic photos demonstrate the fibrous stroma admixed with bone and necrotic debris (white arrow) (A: H&E, ×40) and inflammatory cells (white arrow) and foreign-body giant cell (black arrow) (nuclei arranged haphazardly) in the fibrous stroma (B: H&E, ×200).
Fig. 5Final follow-up left tibia anteroposterior (A) lateral (B) images show bony consolidation of fibular nonunion and bony defect area.
