GUTIERREZ OLIVERA, Natalia del Milagro et al. Osteosintesis percutanea con placas volares bloqueadas en fracturas metafisarias distales de radio: Descripcion de la tecnica y resultados preliminares. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2016, vol.81, n.2, pp.76-83. ISSN 1852-7434.

Objective: To evaluate objective and subjective outcomes after closed reduction and minimally invasive volar locked T-plate osteosynthesis for distal radius fractures with metaphyseal involvement. Methods: We retrospectively evaluated six patients treated with minimally invasive volar locked T-plate osteosynthesis for unstable extra-articular or partial articular distal radius fractures with metaphyseal involvement, between 2007 and 2012. Average age: 40.17 years. According to the AO/OTA classification, all patients had 23A3 type fractures. Indirect reduction was performed. Two volar small incisions were made; a volar locked compression T-plate was introduced in the sub-muscular plane, under radioscopic guidance. Analysis included radiological parameters, range of motion and strength. Subjective results were assessed using DASH score and the Visual Analogue Scale. Results: All fractures healed within 2.4 months. Radiographic outcomes showed no differences between the first postoperative control and the last one at one-year follow-up. Average flexion and extension 70° and 60°, pronation and supination: 79° and 80°. Grip strength: 78.4%. DASH score 19.82 and visual analogue scale: 1.5 points. Conclusions: Minimally invasive technique decreases surgical injury and complications. It is an option in patients with metaphyseal comminution, severe soft tissue injuries and high energy trauma. Percutaneous volar locked compression plate allows to obtain a stable fixation and to restore distal radius anatomy in radius fractures with metaphyseal involvement.
