RUCHELLI, Luis S; MANGUPLI, Martín M; GOMEZ, José M  y  ALLENDE, Bartolomé Luis. Salvataje de fracturas laterales de cadera con clavo-placa de 95º (AO/ASIF). Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2016, vol.81, n.4, pp.281-286. ISSN 1852-7434.

Introduction: Contemporary techniques for reduction and internal fixation make most femoral neck and intertrochanteric hip fractures heal without problems. Most of these fractures are treated with closed reduction and internal fixation achieving excellent results. Treatment failure of hip fractures usually leads to pain and disability. Therapeutic alternatives can be limited to two options, with the exception of the conservative non-operative treatment in critical patients: a new fixation system or an arthroplasty. The valgus osteotomy aims to transform the shear forces in the area of nonunion into compressive forces, thereby stimulating fracture healing. Methods: Fourteen patients with intertrochanteric hip fracture nonunion were retrospectively evaluated between January 2010 and February 2014. All patients underwent revision surgery in order to achieve a valgus position of the proximal fragment, using a 95º blade plate (AO/ASIF). The objective of this study was to evaluate the clinical and radiographic results of intertrochanteric hip fracture nonunion treated with this method. Results: Fracture healing was achieved in all 14 patients. Average healing time ranged from three to six months. The Harris score averaged 82.65. Hardware removal was not performed after fracture healing. Conclusion: The 95° blade plate is still a very good option in cases of proximal femur nonunion, provided the preoperative planning and the surgical technique are correct and the postoperative care is adequate.
