A bone fracture reduction device (110, 500, 600) and system (100, 900, 1000). The bone fracture reduction device (110, 500, 600) may include two fixation apparatuses (51, 51', 400, 10311, 10312) and a control module (54, 1070).The two fixation apparatuses (51, 51', 400, 10311, 10312) may be configured to fix a first portion (561) and a second portion (563) of an object (53), respectively. Each of the two fixation apparatuses (51, 51', 400, 10311, 10312) may include: a base (401, 501) configured to accommodate component(s) of the fixation apparatus (51, 51', 400, 10311, 10312) and being equipped with a guide rail (503); a sliding block (409, 509); a first drive component (413, 513) configured to actuate the sliding block (409, 509) to move along the guide rail (503); a support component (407, 507, 1050) rotatably connected to the sliding block (409, 509); a second drive component (415, 515) connected to the sliding block (409, 509) and configured to actuate the support component (407, 507, 1050) to rotate with respect to the sliding block (409, 509); and a fixing component (419, 519) connected to the support component (407, 507, 1050) via a lifting component (417, 517, 517') and configured to accommodate the first portion (561) or the second portion (563) of the object (53).La présente invention concerne un dispositif (110, 500, 600) et un système (100, 900, 1000) de réduction de fracture osseuse. Le dispositif de réduction de fracture osseuse (110, 500, 600) peut comprendre deux appareils de fixation (51, 51', 400, 10311, 10312) et un module de commande (54, 1070). Les deux appareils de fixation (51, 51', 400, 10311, 10312) peuvent être configurés de sorte à fixer une première partie (561) et une seconde partie (563) d'un objet (53), respectivement. Chacun des deux appareils de fixation (51, 51', 400, 10311, 10312) peut comprendre : une base (401, 501) conçue pour loger un (des) constituant(s) de l'appareil de fixation (51, 51', 400, 10311, 10312) et munie d'un rail
