Patent number: 6030385Abstract: An orthopaedic device for the gradual correction of angular and longitudinal defects of elongated bones, comprising at least one first clamp for a first group of screws insertable in a proximal portion of a bone, and at least one second clamp for a second group of screws insertable in a distal portion of the bone, a longitudinal guide bar positioned externally of the limb to be corrected for slidably supporting the clamps; at least one of the clamps is selectively orientable about a substantially transverse axis for carrying out angular corrections of the bone. There are provided a compression/distraction device movably coupleable with the clamps for carrying out longitudinal corrections of the bone. The orientably clamp is adjustable angularly in a predetermined geometric plane, as well as adjustable transversely for the group of bone screws carried by the clamp parallel to themselves for compensating the lateral movement induced by the angular correction.Type: GrantFiled: February 11, 1998Date of Patent: February 29, 2000Assignee: Orthofix S.r.l.Inventors: Giovanni Faccioli, Daniele Venturini, Sander Ten Veldhuijs

Patent number: 6027506Abstract: An all-mechanical system for bone-drilling alignment of a blind distal bone-screw hole of an installed intra-medullary nail, wherein the system provides (i) a drill jig that features a longitudinally adjustable nail-contactable contact-rod mounting in the jig and (ii) a drill-guide which can align with the blind distal bone-screw hole for a correct nail-contactable adjustment of the contact rod. The system enables the surgeon to check-out the drill jig in assembled relation to a selected intramedullary nail, prior to nail installation, and to perform an adjustment to compensate for nail diameter when the contact end of the rod engages the nail. He can then either visually satisfy himself of the drill-guide/bolt-hole alignment, or he can use a plug-gage or trocar tool having guidance in the drill guide, and checking for whether the plug gage has entry into the bone-screw hole in the intramedullary nail.Type: GrantFiled: June 9, 1998Date of Patent: February 22, 2000Assignee: Orthofix, S.r.l.Inventors: Giovanni Faccioli, Stefano Rossi
