Purpose: The aim of this study was to evaluate clinical availability and advantage of autogenous cancellous bone graft from proximal tibia metaphysis. Materials and Methods: A retrospective review was conducted of 58 cases of foot and ankle surgeries using bone graft from the ipsilateral proximal tibia from August 2008 to March 2012 in Konkuk University Medical Center (Seoul, Korea). The group included patients with isolated reconstructions as well as trauma in the foot and ankle area. Results: The mean volume of cancellous bone harvested from the proximal tibia was 14 ml (range, 5 to 28 ml) and allograft was added to the autogenous bone graft in order to fill the large bone defect for six cases. The bone graft was performed for 41 arthrodesises, seven supramalleolar tibial osteotomies, eight open reduction and internal fixation procedures, and two curettage and bone grafts of bone tumor. At final follow-up, one case (1.7%) showed mild pain on the donor site and the mean visual analogue scale score for pain was 0.1 (range, 0 to 2). There was no occurrence of major post-operative complication at the donor site. Solid union at final follow-up was observed in 97% of cases. Conclusion: Proximal tibial bone graft was found to be a viable alternative to the iliac crest bone graft in the aspect of cancellous bone graft with relatively sufficient quantity and minimal donor site morbidity [ABSTRACT FROM AUTHOR]

Backgroud: The aim of this study was to evaluate results of osteoperiosteal decortication and autogenous cancellous bone graft combined with a bridge plating technique in atrophic and oligotrophic femoral and tibial diaphyseal nonunion., Methods: We retrospectively reviewed 31 patients with atrophic or oligotrophic femoral and tibial diaphyseal nonunion treated with osteoperiosteal decortication and autogenous cancellous bone graft between January 2008 and December 2018. Patients with hypertrophic nonunion, infected nonunion, and nonunion treated with autogenous cancellous bone graft alone were excluded. The nonunion site was exposed by using the Judet technique of osteoperiosteal decortication. Nonunion with a lack of stability was stabilized with a new plate using a bridge plating technique or augmented by supplemental fixation with a plate. Nonunion with malalignment was stabilized with a new plate after deformity correction. Autogenous cancellous bone graft was harvested from the posterior iliac crest and placed within the area of decortication. A basic demographic survey was conducted, and the type of existing implants, mechanical stability of the implants, the type of implants used for stabilization, the operation time, the time to bone union, and postoperative complications were investigated., Results: The average follow-up period was 33.3 months (range, 8-108 months). The operation time was 207 minutes (range, 100-351 minutes). All but 1 nonunion (96.7%) were healed at an average of 4.2 months (range, 3-8 months). In 1 patient, bone union failed due to implant loosening with absorbed bone graft, and solid union was achieved by an additional surgery for stable fixation with a new plate, osteoperiosteal decortication, and autogenous cancellous bone graft. There were no other major complications such as neurovascular injuries, infection, loss of fixation, and malunion., Conclusions: Osteoperiosteal decortication and autogenous cancellous bone graft combined with stable fixation by bridge plating showed reliable outcomes in atrophic and oligotrophic diaphyseal nonunion. This treatment modality can be effective for treating atrophic and oligotrophic diaphyseal nonunion because it is very helpful stimulating bone union., Competing Interests: CONFLICT OF INTEREST: No potential conflict of interest relevant to this article was reported., (Copyright © 2021 by The Korean Orthopaedic Association.)
