Abstract:
(EN) An external fixation device (100) in combination with an electrical stimulus generator (160) for use in the promotion of osteosynthesis in the healing of a bone fracture. Implemented as follows: using a standard external fixation device (160); fix the site of the bone fracture by inserting a first and second pair of fixation pins (112, 114, 122, 124) on each side of the fracture site; fixing at least one cathode (142) in electrical contact with the bone adjacent to the fracture site; and the cyclically applying a voltage between the fixation pins (112, 114, 122, 124) and the cathode (142). Whereby, current flows in a defined cycle from cathode (142) to one of the two pairs of fixation pins (112, 114, 122, 124), then from one pair of pins to the other, then from the cathode (142) to the other pair of electrodes.
(FR) Dispositif de fixation externe (100) combiné avec un générateur de stimuli électrique (160) à utiliser pour promouvoir l'ostéosynthèse lors de la cicatrisation d'une fracture d'un os. Il est utilisé de la manière suivante: on emploie un dispositif de fixation externe standard (160), on fixe le site de la fracture de l'os en insérant une première et une seconde paires de broches de fixation (112, 114, 122, 124) de chaque côté du site de la fracture, on fixe au moins une cathode (142) en contact électrique avec l'os près du site de la fracture et on applique de manière cyclique une tension entre les broches de fixation (112, 114, 122, 124) et la cathode (142). Cela permet au courant de s'écouler dans un cycle défini depuis la cathode (142) à l'une des deux paires de broches de fixation (112, 114, 122, 124), puis d'une paire de broches à l'autre puis de la cathode (142) à l'autre paire d'électrodes.
