    PurposeThe objective of this study was to assess the efficacy of augmentation plating with retaining of previous implant in situ in cases of non-united oligotrophic or atrophic aseptic distal tibial diaphyseal and metaphyseal fractures without bone grafting depending on the unified bone healing and non-union theory.MethodsThrough the period between December 2019 and December 2022, twelve patients with distal third tibial non-unions who were fixed at time of fracture either by intramedullary interlocking nails (seven cases) or by minimally invasive plate osteosynthesis (five cases) were included. Non-union was diagnosed on basis of absence of any healing progression in three months period or absence of fracture healing after six months from index surgery. All patients had oligotrophic or atrophic non-union. Augmentation plating through an anterolateral approach was done on average of 7.25 months after initial surgery (6-9 months). Circumferential exposure of the fracture site and debridement of fibrous tissue were not necessary. No bone grafting was done as no cases had major bone defect.ResultsAll patients achieved complete radiological union with a mean time of 21.8 weeks (range 18-30 weeks) that mean full callus formation in all cortices. All patients were walking independently after three months (13weeks) from surgery and returned to work even in cases of absent complete radiological union. No cases had been complicated with wound healing problems (infection or dehiscence). One patient had incomplete ankle dorsiflexion (10°) due to tight calf muscles and one patient had paresthesia on the dorsum of the foot that was not improved at last follow up (one year after surgery).ConclusionAugmentation plating is a safe and effective option for management of distal tibial diaphyseal nonunion even in cases of oligotrophic or atrophic non-union.Copyright © 2023 Elsevier Ltd.
