To study the safety and efficacy of staged reconstruction of distal femoral (supracondylar) bone loss using autologous fibular strut, cortico-cancellous bone grafting.Single-centre, observational study, with review of literature.Urban Level I Trauma Center.Eighteen consecutive patients (mean age: 35 ± 8.5 years, all males) with open supracondylar fracture and intercondylar extension (OTA/AO type C3), operated between January 2010 and February 2014 with severe bone loss in 11 patients and moderate loss in 7.Single free fibular strut was used in 12 femurs and dual fibula in 5 femurs with autologous cortico-cancellous bone grafting in all.Clinical union, radiological union, and knee function using the Sanders' score.Mean follow-up was 45.5 ± 17 months. The mean radiological union time was 18 ± 2.6 weeks. Functional assessment after union revealed one patient with excellent knee function, 9 with good, 8 with fair, function according to Sanders' scoring. The mean knee range was 49 degrees (range 5–110 degrees) in which 9 patients achieved a knee range >80 degrees. Mean limb shortening was 2 cm (range 0–7 cm). No limb shortening was observed in 5 patients. Patients were pain free and had no significant graft or donor site morbidity.Staged fibular strut grafting, cortico-cancellous bone grafting for traumatic open supracondylar femoral fractures with significant bone loss is a promising technique with a good safety profile and long-term efficacy.Therapeutic Level IV.
