Method and apparatus for mandibular osteosynthesis
First Claim
1. An apparatus for osteosynthesis of a mandible comprising:
- an elongated plate having a plurality of apertures, said plate having a portion A, a portion B, and a portion C, each of said plurality of apertures within said portion A and within said portion B being disposed in relatively close spaced relationship, and each of said plurality of apertures within said portion C being disposed in relatively widely spaced relationship, wherein said plate between next adjacent apertures within said portion A has a first width, and said plate between next adjacent apertures within said portion C has a second width, said second width being substantially less than said first width.

Abstract
An apparatus for osteosynthesis of a mandible. An elongated plate has a plurality of apertures. The plate has a first portion, a second portion, and a central portion intermediate the first and second portions. Each of the apertures within the first portion and within the second portion are disposed in relatively close spaced relationship, and each of the apertures within the central portion are disposed in relatively widely spaced relationship. The width of the plate between apertures is less in the central portion than in the first portion. The plate is more easily bent within the central portion than within the first portion, and can be bent to a relatively small radius in the central portion without distorting the apertures within the central portion. The central portion is sized and located to overlie the symphysis of the mandible.

31. A method of surgically repairing a mandible comprising the steps of:
-
a) providing an elongated plate having a plurality of apertures, said plate having a portion A and a portion B, each of said plurality of apertures within said portion A being disposed in relatively close spaced relationship, and each of said plurality of apertures within said portion B being disposed in relatively widely spaced relationship;
b) providing a fastener having means for engaging said mandible and having means for engaging an aperture of said plate;
c) securing said elongated plate to said mandible with said fastener; and
d) bending said plate to substantially conform to said mandible such that said central portion overlies the symphysis of said mandible.

32. An apparatus for osteosynthesis of a mandible comprising:
-
an elongated plate operable to be attached to the mandible, said elongated plate including;
a single row of apertures disposed longitudinally along said elongated plate;
a first portion having at least three apertures of said single row disposed therein;
a second portion having at least another three apertures of said single row disposed therein;
the distance between each next-adjacent aperture of said at least three apertures of said first portion being greater than the distance between each next-adjacent aperture of said at least another three apertures in said second portion.

33. An apparatus for osteosynthesis of a mandible having a symphysis and a posterior portion and adapted for fastening to the mandible by fasteners, said apparatus comprising:
-
an elongated plate defined by a length greater than its width and having a first portion, a second portion, and a generally central portion intermediate said first and second portions; and
a plurality of apertures disposed in a row along said length of said elongated plate and including at least three next-adjacent apertures in said first portion and at least three next-adjacent apertures in said second portion spaced closer together than at least three next-adjacent apertures in said central portion, said central portion operably appliable to the symphysis by the fasteners to allow unimpeded fastening of said elongated plate to the mandible.

34. An apparatus for osteosynthesis of a mandible having a symphysis and a posterior portion and adapted for fastening to the mandible by fasteners, said apparatus comprising:
-
an elongated plate operable to be attached to the mandible, said elongated plate including;
a single row of apertures disposed longitudinally along said elongated plate;
a first portion having at least three next-adjacent apertures disposed therein;
a pre-contoured second portion having at least another three next-adjacent apertures disposed therein;
wherein said at least three next-adjacent apertures within said first portion are disposed in relatively closely spaced relationship and said at least another three next-adjacent apertures within said pre-contoured second portion are disposed in relatively widely spaced relationship, and wherein said second portion is operably appliable to the symphysis and said first portion is operably appliable to the posterior portion of the mandible, the relatively widely spaced relationship of said at least three next-adjacent apertures within said second portion allowing unimpeded fastening of said elongated plate to the mandible by the fasteners.
