Mean follow-up period was 3.8 (range: 2.2 to 9.0) years. The displaced lesser trochanteric fragment was reduced anatomically and fixed with 16-gauge stainless steel cerclage wire. Clinical outcomes included Harris Hip Score (HHS), thigh pain, groin pain and walking ability. Radiographic outcomes included stem fixation and stability, osteolysis, heterotopic ossification and subsidence. The stable reduction group was determined when anatomic reduction of posteromedial fragments was achieved with ?1 mm gap of fragment.\n\nResults: Mean HHS was 82 (range: 78 to 99) at the final follow-up. Thirty-one hips (21.7%) experienced thigh pain and 19 (13.3%) groin pain. One hundred and twelve patients (80.6%) regained their pre-injury level of ambulation. All femoral stems showed osseointegration without aseptic loosening and osteolysis. The mean stem subsidence was 3.1\u00b12.4 (range: 0 to 18) mm. The extent of subsidence was significantly higher in patients with unstable reduction. The survival rate was 94.2%.\n\nConclusion: Cementless bipolar hemiarthroplasty appears to be a suitable method for the treatment of intertrochanteric fracture in octogenarians. However, stable fixation of the posteromedial fragment is necessary to avoid stem subsidence.\n\n \n\n\u00d6zet\n\n \n\nAma\u00e7: Bu \u00e7al\u0131\u015fman\u0131n amac\u0131, sekizinci dekatta bulunan hastalarda instabil intertrokanterik k\u0131r\u0131klar i\u00e7in sementsiz stem ile bipolar hemiartoplastinin klinik ve radyografik sonu\u00e7lar\u0131n\u0131 de\u011ferlendirmek ve stemin \u00e7\u00f6kmesi ile ili\u015fkilendirilen etmenleri belirlemek idi.\n\n\u00c7al\u0131\u015fma plan\u0131: \u00c7al\u0131\u015fmaya 139 (119 kad\u0131n, 20 erkek) hastaya ait 143 kal\u00e7a dahil edildi.
