Event Description
This report is being filed after the review of the following journal article: cho, u. , byun, y. S. , suh, j. D. , yoo, j. (2021), osteoperiosteal decortication and autogenous cancellous bone graft combined with bridge plating for non-hypertrophic diaphyseal nonunion, clinics in orthopedic surgery, vol. 13, pages 301-306 (south korea). 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. 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. Seventeen nonunion cases with implant breakage or loosening and 1 nonunion case with malalignment were stabilized with 10- to 12-hole large fragment locking compression plates (lcp) (7 cases), 7- and 9-hole condylar blade plates (2 cases), or 9- to 12-hole lcp distal femur (8 cases) using a bridge plating technique after removal of the existing implants and correction of any malalignment. Twelve nonunion cases with a lack of stability without implant breakage or loosening were augmented by supplemental fixation with 6- to 10-hole small fragment or reconstruction lcp. One nonunion was fixed with a locked intramedullary nail and showed adequate stability without further support for improving stability. There were 20 men and 11 women, and the mean age of patients was 51. 7 years (range, 19¿79 years). The average follow-up period was 33. 3 months (range, 8¿108 months). The following complications were reported: in 1 patient, 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. This report is for an unknown synthes lcp construct. This is report 1 of 2 for (b)(4).
