Abstract:
1. A percutaneous implant device, comprising: a. a biologically compatible metal alloy implant stem and a porous metal outer body member adapted for bone and soft tissue in-growth; b. said implant stem having a male tapered fluted stem portion adapted to be inserted into a female tapered cavity drilled within a bone of a broken limb; c. said implant stem having a cylindrical inner portion extending from and abutting said male tapered fluted stem portion, the cylindrical inner portion having a cylindrical core diameter adapted for press fitting said porous metal outer body member thereon; d. said porous metal outer body member having a central aperture with a bore diameter that is smaller than said cylindrical core diameter by an interference amount to integrally mate said porous metal outer body member with said cylindrical inner portion of the implant stem; e. said implant stem having a suture ring abutting said cylindrical inner portion and located distal from said male tapered fluted stem portion; f. one end of said porous metal outer body member abutting said suture ring; g. another end of said porous metal outer body member distal from said suture ring having a female taper abutting said male tapered fluted stem portion and being adapted to fit around and mate with a male taper surgically created on a bone end; h. said implant stem having an external member integral to said implant stem extending from said suture ring adapted for attachment to a hand of foot prosthesis; whereby the porous metal outer body is adapted to be press fit over the cylindrical inner portion so that said percutaneous implant device functions as a single unit; whereby the male tapered fluted stem portion and the female taper of the porous metal outer body are adapted for bone contact, generating bone in-growth; whereby said suture ring is adapted for suturing soft tissue thereto; whereby said outer surface of said porous metal body member is adapted to contact soft tissue generating soft tissue in-growth and thereby preventing lateral and longitudinal displacement of said percutaneous implant during healing and promoting bone and soft tissue in-growth.
