Title
(EN) APPARATUS AND METHOD FOR ENHANCING BONE FORMATION
(FR) APPAREIL ET METHODE D'AMELIORATION DE LA FORMATION OSSEUSE
Abstract
(EN)
Apparatus and methods enhance bone formation. The methods and apparatus provide a mechanical load (60a, 60b) applied to the epiphysis (44, 45, 62) of a bone (24, 26, 64) associated with a joint (22). The magnitude of the mechanical load is oscillated and is applied periodically for a short durations of time. The applied mechanical force induces formation of trabecular (70) and cortical (68) bones. Embodiments of the apparatus include passively and actively actuated bands (28, 128, 228, 328) which are positioned around at least a portion of a joint and provide mechanical loading on the joint, for example, on the epiphysis of a bone and oriented traverse (54, 76) to the longitudinal axis (56, 78) of the bone.
(FR)
L'invention concerne un appareil et des méthodes permettant d'améliorer la formation osseuse. Ces méthodes et cet appareil comportent une charge mécanique (60a, 60b) appliquée sur l'épiphyse (44, 45, 62) d'un os (24, 26, 64) lié à une articulation (22). L'ampleur de la charge mécanique oscille et est appliquée périodiquement pour de courtes périodes de temps. La force mécanique appliquée permet d'induire la formation d'os trabéculaires (70) et de corticales (68). Des modes de réalisation de cet appareil ont trait à des bandes actionnées passivement et activement (28, 128, 228, 328) qui sont placées autour d'au moins une partie d'une articulation, qui engendrent une charge mécanique sur l'articulation, par exemple, sur l'épiphyse d'un os et qui sont orientés transversalement (54, 76) à l'axe longitudinal (56, 78) de l'os.
