Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
Osteosynthetic single-piece compression plate (1) with a plurality of holes (2) disposed along the longitudinal axis (5) of the compression plate (1) for the insertion of bone screws, characterized in that the cross-sectional area (6) of the compression plate (1), which is orthogonal to the longitudinal axis (5) of the plate (1), has, at least in a segment (7) of the plate length, a trapezoidal form, whereby the shorter basis of the trapezoidal cross-sectional area (6) corresponds to the bone application line (3a), which is formed by the intersection of the bone application surface (3) and the cross-sectional area (6) orthogonal to the longitudinal axis (5) of the plate (1)
Claim 2
Dependent Claim
110 words
Osteosynthetic single-piece compression plate (1) with a plurality of holes (2) disposed along the longitudinal axis (5) of the compression plate (1) for the insertion of bone screws, characterized in that the cross-sectional area (6) of the compression plate (1), which is orthogonal to the longitudinal axis (5) of the plate (1), has, at least in a segment (7) of the plate length, a trapezoidal form, whereby the shorter basis of the trapezoidal cross-sectional area (6) corresponds to the bone application line (3a), which is formed by the intersection of the bone application surface (3) and the cross-sectional area (6) orthogonal to the longitudinal axis (5) of the plate (1)
Claim 3
Dependent Claim
57 words
Osteosynthetic compression plate (1) according to claim 1, characterized in that the non- parallel, lateral surfaces (8) adjacent to the bone application surface (3) of the trapezoidal cross- section of the compression plate (1) are forming an exterior angle with the bone application surface (3) in the range from 10° - 70°, preferably from 30° - 50°.
Claim 4
Dependent Claim
22 words
Osteosynthetic compression plate (1) according to claim 1 or 2, characterized in that the enlargement of the cross-sectional area (6) is continuous.
Claim 5
Dependent Claim
22 words
Osteosynthetic compression plate (1) according to claim 1 or 2, characterized in that the enlargement of the cross-sectional area (6) is discontinuous.
Claim 6
Dependent Claim
31 words
Osteosynthetic compression plate (1) according to one of the claims 1 to 4, characterized in that the bone application line (3a) is degenerated - at least partially - to a point.
Claim 7
Dependent Claim
28 words
Osteosynthetic compression plate (1) according to one of the claims 1 to 4, characterized in that the bone application surface (3) is degenerated to a segment-like, broken line.
Claim 8
Dependent Claim
35 words
Osteosynthetic compression plate (1) according to one of the claims 1 to 4, characterized in that the bone application surface (3) is degenerated to a series of points which are disposed along a straight line.
