Doughnut-like spinal implant

A biocompatible metallic, plastic or combined metallic-plastic doughnut-like implant capable of frontal insertion between a superior and inferior lumbosacral vertebra, wherein said doughnut-like implant comprises a plurality of distinct generally upright load supporting curvatures;

• said doughnut-like implant further comprising:
• a) an asymmetrical central opening, including a central vertical axis, surrounded by said plurality of distinct generally upright load supporting curvatures;
• b) an anterior member, of said plurality of distinct generally upright load supporting curvatures, protruding forward and away from said central vertical axis;
• said anterior member further comprising one or more apertures proximate an inferior edge of said anterior member;
• c) a posterior member, of said plurality of distinct generally upright load supporting curvatures, protruding forward and toward said central vertical axis;
• said posterior member angled more acutely than said anterior member;
• d) a first tapered lateral member, of said plurality of distinct generally upright load supporting curvatures, intermediate between and connected with said anterior and said posterior members;
• said first tapered lateral member comprising an upper boundary and a lower boundary that taper toward each other as said first tapered lateral member traverses from said anterior member to said posterior member;
• e) a second tapered lateral member, of said plurality of distinct generally upright load supporting curvatures, intermediate between and connected with said anterior and said posterior members;
• said second tapered lateral member comprising an upper boundary and a lower boundary that taper toward each other as said second tapered later member traverses from said anterior member to said posterior member;
• f) a forwardly extending arm attached proximate an upper edge of said anterior member;
• and
• g) a plate, comprising an aperture, connected with said forwardly extending arm, wherein said plate extends upward from said forwardly extending arm.

A biocompatible doughnut-like implant capable of frontal insertion between a superior and an inferior vertebra;

• said doughnut-like implant comprising:
• a) an asymmetrical opening comprising a reference generally vertical axis;
• b) distinct load bearing curvatures surrounding said asymmetrical opening;
• said distinct load bearing curvatures comprising superior and inferior edges;
• c) a porous coating applied to one or more of said superior or inferior edges;
• d) a first load bearing curvature, of said load bearing curvatures, protruding forward and away from said reference axis;
• said first load bearing curvature further comprising one or more apertures proximate an inferior edge of said first load bearing curvature;
• e) a second load bearing curvature, of said load bearing curvatures, protruding toward said reference axis, wherein said second load bearing curvature is angled more acutely than said first load bearing curvature;
• f) third and fourth load bearing curvatures, intermediate between and connected with said first load bearing curvature and said second load bearing curvature;
• and
• g) a reference plane bisecting said third and fourth load bearing curvatures.

A biocompatible doughnut-like implant capable of frontal insertion between a superior and an inferior vertebra;

• said doughnut-like implant comprising an opening enclosed by a series of interconnected load bearing generally upright sections, wherein adjacent sections forming said opening of said interconnected load bearing generally upright sections include distinct curvatures, and wherein said series further comprises:
• a) an anterior section protruding forwardly and comprising one or more apertures proximate an inferior edge of said anterior section;
• b) a posterior section protruding forwardly and angled more acutely than said anterior section;
• c) first and second opposed lateral sections intermediate between and connected with said forward and said rearward sections;
• and
• d) a reference plane bisecting said first and said second opposed lateral sections.
