Reduction and intramedullary fixation of subtrochanteric fractures is often challenging. Osteosynthesis frequently fails and a higher rate of non-unions is found. The aim of this study was to evaluate the benefit of an additional cerclage to anatomically reduce and support the medial hinge. The application is based on the experience of the surgeon; as yet no biomechanical data are available. ⋯ In view of the more invasive operative approach with additional soft tissue injuries, application of an additional cerclage should still be considered carefully. Nevertheless, a mini-open approach to difficult fractures could be helpful in reducing the fracture with a clamp and is sometimes essential. The damage to the soft tissue must be weighed against the benefits of the procedure. An additional cerclage in oblique subtrochanteric fractures is a good option to ensure the reposition and cortical medial support if appropriate and to decrease osteosynthesis failure and rates of non-unions.
