  • a transtibial amputation is an amputation of the lower limb below the knee.
  • a transtibial prosthesis is an artificial limb that replaces the portion of the leg below the knee that is missing.
  • the shape of the residual limb varies for each individual and generally requires a custom-fitted prosthesis.
  • a custom-rfitted prosthesis that is comfortable is difficult to fabricate and costly.
  • the initial cost of a conventional prosthesis for a transtibial amputee typically ranges from $6000 to $14,000. In addition, there are additional costs to ensure the comfort and functionality of the device.
  • the present state of prosthesis fabrication often requires three or more visits to the prosthetist and there are multiple steps in the fabrication process. First, a cast mold of the residual limb is made and a positive cast that resembles the residual limb is generated. Then, a prosthetic socket is built to custom-fit over the positive cast. Sometimes a check or temporary socket is made to insure a better fit. Typical fabrication techniques require specialized facilities. Generally, the final prosthesis requires post-fabrication adjustments as the residual limb tissue changes over time.
  • Residual limbs may also grow or otherwise change shape, which may occur rapidly. In some instances, it may be necessary to replace a prosthetic device every six months to a year. It is desirable to create a prosthetic device which is adjustable to provide continued support and comfort as a residual limb changes.

Abstract

L'invention concerne un dispositif prothétique modulaire à ajustement rapide qui peut être fabriqué à bas coût à l'aide d'une technologie de modem et de matériaux polymères de pointe. Le dispositif prothétique modulaire à ajustement rapide sera immédiatement adapté au membre résiduel et aligné pour une démarche optimale sans outils ni laboratoires spécialisés, réduisant les nombreuses étapes intervenant dans une construction classique de prothèse onéreuse nécessitant une main-d'œuvre importante. Le dispositif prothétique modulaire à ajustement rapide s'adapte également au changement de dimension et de forme du membre, éliminant le besoin de multiples prothèses et ajustements à une prothèse existante pendant la vie d'une personne amputée.
