Abstract Introduction In a Monteggia fracture dislocation, it is important to reduce the ulnar fracture completely.Extensive plastic deformation of the proximal ulna may make reduction by closed manipulation impossible.Case presentation We Hockey Masks report the case of a four-year-old Caucasian boy in whom the plastic deformation of the proximal ulna Twin Bookcase Storage Bed was reduced, and this reduction was maintained, using intra-medullary stacked nailing.Conclusion The technique of stacked nailing is a useful addition to the armamentarium in the management of the potentially awkward Monteggia fracture.
