摘要:
A system for interconnecting fractured femoral bone segments comprising: a marking tool for marking skin; a guiding device for advancing a first guide wire into the proximal end region and for guiding the drilling of a central bore for a screw; an alignment arrangement including second and third guide wires inserted substantially parallel to the central bore and indicating the correct insertion distance for the intramedullary nail inside the femur for fixation at the proximal end of the femur; a targeting jig including a first arm and a corresponding second arm arranged substantially parallely to the first arm, the first arm having a graduated scale on its free end region and the second arm having a similarly graduated scale; an insertion tool attachable to a proximal end of an Intramedullary nail and for insertion of the nail into a medullary canal of femur; one or more marking tools for further marking the skin in two substantially orthogonal planes at the distal end of the femur; a distal fixation jig including lateromedial and anteroposterior guiding parts-arranged substantially orthogonal to each other.
摘要:
A surgical bone rasp includes a body having posterior, anterior, medial, and lateral surfaces. The medial surface includes a proximal curved portion shaped to extend substantially along a concave medial curve. The proximal curved portion includes a plurality of teeth. Each tooth in the plurality includes a tooth gullet wall, a tooth undercut, and a tooth land between the proximal and tooth undercuts. The tooth lands can be generally flat and can extend along the concave medial curve. The tooth gullet walls can be parallel to one another and can be angled to extend away from the body between a distal direction and a medial direction. The tooth undercuts can be parallel to one another, can be angled to extend away from the body in a medial direction, and can be equally spaced apart along the longitudinal axis.

A scalable modular hip resurfacing arthroplasty system includes (1) an alignment guide 204 for precise guide pin insertion, (2) a modular cannulated cylindrical reamer assembly 710 for accurate femoral head cylindrical reaming and central bone channel drilling, (3) a saw guide 1004 for an accurate femoral head osteotomy, (4) a soft tissue protector 1200 with a stepped design to shield and retract tissues, (5) a hip retractor 1500 that seats onto a prepared femur, (6) an outer hole drill guide 1700 aiding drilling of peripheral holes, and (7) a femoral resurfacing implant 2010 with a cap portion and central stem adapted for multiple modular attachments including plates. A method for preparing the proximal femur for hip resurfacing with novel stepped cylindrical femoral head osteotomy and central bone channel drilling, leaving an intact collar of cortical bone above the femoral head articular rim.

La présente invention concerne un manche (1) amovible pour une râpe (2) chirurgicale ou similaire, le manche (1) et la râpe (2) coopérant au droit de leurs extrémités d'assemblage par des faces de contact au moins sécantes à la direction moyenne de transmission des efforts entre le manche (1) et la râpe (2), ledit manche (1) comportant un dispositif d'assemblage (5) démontable et étant caractérisé en ce que le dispositif d'assemblage (5) démontable comporte, d'une part, un moyen d'assemblage (6) par emboîtement, selon une direction globalement perpendiculaire aux dites faces de contact, mettant en oeuvre au moins deux organes complémentaires: un tenon (7) creux et une mortaise (8) et, d'autre part, un moyen de verrouillage (9) desdits organes complémentaires (7, 8) en leur position emboîtée c'est à dire lorsque le manche 1 amovible et la râpe (2) sont solidarisés, leurs faces de contact étant appliquées l'une contre l'autre.
摘要:
The present invention relates to a medical implant for reducing pain in diseased joints such as synovial joints, in particular ball and socket joints such as the hip joint and the shoulder joint. One embodiment relates to a medical implant for attachment to and at least partly covering the femoral head, said medical implant comprising a dome shaped shell with an orifice, said shell having a height h1, an equatorial shell radius rs and an orifice radius ro wherein the shell radius rs > ro, and h1> rs, and the orifice is defined by a circumferential rounded edge.
