Autogenous bone grafting were performed for all cases. The mean age of the patients was 49.1 years in Group 1, and 48.2 years in Group 2. The mean follow-up period was 19.3 months. \\r\\nResults: The union rate was 100% in Group 1, and 77.8% in Group 2 (p&lt;0.05). The average time of union was 7.6 months in Group 1, and 6.9 months in Group 2. The mean preoperative leg length discrepancy (LLD) was 8.3 mm in Group 1, 10.0 mm in Group 2; and the mean final LLD was 13.9 mm in Group 1, and 11.2 mm in Group 2. The mean length of hospital stay was 23.8\u00b13.3 days in Group 1, and 18.2\u00b12.7 days in Group 2; the mean amount of blood transfusion was 960 ml in Group 1, and 647 ml in Group 2; and the mean operative time was 3.7\u00b10.8 hrs in Group 1, and 2.7\u00b10.6 hrs in Group 2 (p&lt;0.05).\\r\\nConclusion: The union rate in patients with exchange of the previous hardware was better than in those with retained hardware in the treatment of subtrochanteric nonunion by complete removal of the interposed fibrous tissue and meticulous bone grafting leading to a biological environment to achieve bony union.\n\n\n\u00d6zet\n\nAma\u00e7: \u00c7al\u0131\u015fmam\u0131z\u0131n amac\u0131 kaynamayan subtrokanterik k\u0131r\u0131k tedavisinde daha \u00f6nce yerle\u015ftirilen fiksat\u00f6r\u00fcn ek bir tespit ile yerinde b\u0131rak\u0131lmas\u0131 ve daha \u00f6nceki fiksat\u00f6r\u00fcn de\u011fi\u015ftirilmesinden olu\u015fan iki ayr\u0131 y\u00f6ntemle elde edilen klinik sonu\u00e7lar\u0131 kar\u015f\u0131la\u015ft\u0131rmakt\u0131.\\r\\n\u00c7al\u0131\u015fma plan\u0131: \u00c7al\u0131\u015fmam\u0131zda kaynamayan 19 subtrokanterik k\u0131r\u0131k geriye d\u00f6n\u00fck olarak analiz edilerek, daha \u00f6nceki fiksat\u00f6r\u00fcn de\u011fi\u015ftirildi\u011fi 10 olgu (Grup 1) ile daha \u00f6nceki fiksat\u00f6r\u00fcn ek bir tespit ile yerinde b\u0131rak\u0131ld\u0131\u011f\u0131 9 olgunun (Grup 2) klinik sonu\u00e7lar\u0131 kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131.
