Abstract
Aim and methods: We present our results on the treatment an outcome of femoral non-unions in our institution as tertiary referral centre. Retrospective analysis was performed using the ASAMI criteria.
Results: 19 patients, 12 men and 7 women were retrospectively assessed. Mean age was 40 years (range 17–72). 11 fractures were in the diaphysiseal area and 8 were in the supracondylar area. 5 cases were infected non-unions. Time from fracture to definitive treatment varied from 5 to 88 months (mean 21 months).
Open technique was used in 18 cases. In 8 cases we have used autogenous cancellous bone graft and in 3 cases BMP7 was used in addition to bone graft. 9 cases were treated with Ilizarov frame without bone graft, 6 with plate and bone graft, 3 with intramedullary nail and 1 with bone graft alone. Internal bone transport was carried out in 5 cases to achieve limb length equality.
Fracture union was achieved in 16 patients with 7 excellent and 8 good results as per ASAMI criteria. 15 cases achieved excellent to good functional results. Because of persistent infection, 2 distal femoral non-unions required transfemoral amputation. Treatment was discontinued due to psychiatric illness in 1 patient with Ilizarov frame. Two of the patients in supracondylar group developed knee stiffness. Pin tract infection is a common complication in Ilizarov group.
Conclusion: Adequate reduction and stabilization is key to success. Non-unions without any complications can be treated with exchange nail or open reduction and plating. Ilizarov method is effective for non-unions complicated by distal location, infection and bone loss. Psychological assessment is important before considering Ilizarov method of treatment.
