PURPOSE This study was designed to assess the necessity of additional supporting fixation to the traditional internal fixation for unstable intertrochanteric fractures of femur. MATERIALS AND METHODS Seventy two cases of unstable intertrochanteric fractures (modified Boyd-Anderson type III, IV) in the elderly were reviewed, which were internally fixed with Dynamic Hip Screw. 48 cases were treated with Dynamic Hip Screw only(Group I) and 24 cases with Dynamic Hip Screw and additional trochanteric supporting plate(Group II). In 13 cases with weak femoral cortx, we added wiring to the side plate. We measured neck-shaft angle, degrees of displacement of greater trochanteric fragment, slippage of hip screw on plain radiographs. RESULTS Varus change in neck-shaft angle, displacement of greater trochanteric fragment and slippage of hip screw revealed 7.3°, 5.4 mm, and 10.7 mm respectively in group I, while 2.1°, 0.1 mm and 3.8 mm respectively in group II. There were no pullout of cortical screws. CONCLUSION Internal fixation with additional trochanteric supporting plate to the conventional Dynamic Hip Screw was effective in unstable intertrochanteric fractures of the femur in the elderly. Added wiring to the side plate was also helpful in weak femoral cortex.
The purpose of this study is to evaluate the efficacy of augmentative plate fixation for the femoral nonunion after intramedullary nailing. We reviewed eleven femoral nonunion after intramedullary nailing, which were treated with augmentative plate internal fixation. All cases were initially managed with interlocking intramedullary nailing. Five were hypervascular and six were avascular. Leaving the intramedullay nail in situ, an augmentative plate fixation was applied to the fracture site to counter the rotational instability. A simultaneous bone grafting was performed in six avascular nonunion to repair the bony defect. The union time was 8.2 months in average( 7.8 months in hypervascular and 8.5 months in avascular). In conclusion, augmentative plating leaving the intramedullary nail in situ is an useful alternative for the treatment of femoral nonunion after intramedullary nailing. The technique is simple and does not require any special instruments. It facilitates an early weight bearing and gives a quick recovery from nonunion.
