摘要

Despite recent improvements in osteotomy techniques and the development of new strategies to prevent hinge fractures, a certain rate of hinge fractures still remains after high tibial and distal femoral osteotomies, negatively affecting functional, radiologic, and patient-reported outcomes. Type II/III tibial fractures and dislocated fractures leading to biomechanical instability of the osteotomy are unfavorable predictors of unintended over- and undercorrection, delayed or absent bone healing, and implant failure with secondary loss of correction. Therefore, fracture-specific treatment with reduction of correction loss, additional osteosynthesis of the fractured hinge, and autologous cancellous bone grafting should be considered in daily clinical practice to reduce complication rates and improve bone healing. However, the success of hinge fixation must still be confirmed in clinical trials.
