Abstract
In this study, we aimed to show the results of exchange nail and decortication in patients whose subtrochanteric femur fractures were treated with intramedullary nails and subsequently developed fracture nonunion and nail breakage com- plications. This study consisted of patients presenting with subtrochanteric femur fractures between January 2013 and April 2019 who underwent surgery and later experienced nail breakage due to hypertrophic nonunion. There were a total of 10 patients aged 26-62 years (Avg 40,30, SD: 9,989). Nine patients were smokers, and 1 patient had diabetes and hypertension. Three patients were admitted to the trauma center due to a car accident and 7 patients were admitted because of a fall. The infection parameters of all patients were normal. All patients had pathological movement complications and pain at the fracture site. Preoperatively, medulla diameter was measured with standard radiography in all patients. The diameters of the old nails applied to the patients ranged from 10 to 12 mm, and the diameters of the newly applied nails ranged from 14 to 16 mm. The fracture lines of all patients were opened to remove the broken nails, and decortication was performed. No additional autograft or allograft was applied to any patient. Union was achieved in all patients. We conclude that the use of larger diameter nails in conjunction with decortication will prevent nail breakage, improve healing and provide early union in patients with subtrochanteric femur fractures with hypertrophic pseudoarthrosis.
