Successful Reimplantation of Extruded Ulnar Diaphyseal Segment: A Case Report and Review of Literature.

Case: A 32-year-old man presented with a type II open both-bone forearm fracture and segmental bone loss because of complete extrusion of a diaphyseal fragment (3 cm) of ulna. The patient presented to our level 1 trauma center after a motor vehicle collision. The extruded segment underwent sterilization and immediate reimplantation with internal fixation approximately 6 hours after arrival. Our patient achieved union by 7-month follow-up, demonstrated excellent functional outcomes, and was free from infection at 1-year follow-up.

Conclusion: In select cases, successful reimplantation can be achieved by meticulous debridement, sterilization, and immediate reimplantation with internal fixation.
