RESUMEN
UNLABELLED: To evaluate objective and subjective outcomes after minimally invasive volar locked plate fixation of distal radius fractures with metaphyseal extension, we retrospectively evaluated 13 patients with unstable distal radius fractures with metaphyseal extension, treated by minimally invasive volar locked plating. Patients' average age was 41 years. Two volar incisions, 2 to 3cm long, were made; indirect reduction was performed and a volar locked T-plate was placed submuscularly under fluoroscopy guidance. Twelve fractures healed after an average of 2.46 months; one patient needed revision due to a new injury. The plate had to be removed in one patient. On X-rays, radial height averaged 12.78mm, radial inclination averaged 21.34° and volar tilt averaged 8.22°. Flexion averaged 75°, extension 71.5°, pronation 82.08° and supination 83.08°. Grip strength averaged 83.75% of the contralateral wrist. The DASH score averaged 13.91 points and pain assessed on VAS averaged 0.92 points. In unstable distal radius fractures with metaphyseal extension, minimally invasive plate osteosynthesis using volar locked plates led to good reduction and stable fixation, with low pain levels, and good functional and esthetic results. Indirect reduction techniques, fluoroscopy, and restoration of radial length, rotation and alignment, are necessary to achieve these outcomes. LEVEL OF EVIDENCE: IV.
