Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 114 words
An internal fixation device comprising: an elongated member comprising metal having a generally silver color and including a first end portion, said first end portion having an external thread and having a region coated with titanium nitride which borders an uncoated region at a first borderline; and a first component having an internal thread for engaging said external thread on said first end portion, said coated region on said first end portion being axially so located as to be visible prior to said first end portion disengaging from said first component when said elongated member is rotated in a direction which causes said first component to move outwardly relative to said first end portion.
Claim 2
Dependent Claim 114 words
An internal fixation device comprising: an elongated member comprising metal having a generally silver color and including a first end portion, said first end portion having an external thread and having a region coated with titanium nitride which borders an uncoated region at a first borderline; and a first component having an internal thread for engaging said external thread on said first end portion, said coated region on said first end portion being axially so located as to be visible prior to said first end portion disengaging from said first component when said elongated member is rotated in a direction which causes said first component to move outwardly relative to said first end portion.
Claim 3
Dependent Claim 103 words
The device of claim 1 wherein said elongated member further includes: a second end portion having an external thread and a region coated with titanium nitride which borders an uncoated region at a second borderline; and a second component having an internal thread for engaging said external thread on said second end portion, said coated region on said second end portion being axially so located as to be visible prior to said second end portion disengaging from said second component when said elongated member is rotated in a direction which causes said second component to move outwardly relative to said second end portion.
Claim 4
Dependent Claim 11 words
The device of claim 2, wherein said coated regions are gold-colored.
Claim 5
Dependent Claim 26 words
The device of claim 2, wherein said coated region of said first end portion is axially longer than said coated region of said second end portion.
Claim 6
Dependent Claim 23 words

Claim 8
Dependent Claim 19 words
The device of claim 2, wherein said internal thread of one of said components has a titanium nitride coating.
Claim 9
Dependent Claim 37 words
The device of claim 1, wherein said elongated member includes a middle portion having a hexagonal cross-section for allowing said elongated member to be gripped and turned, said hexagonal portion being located between said two end portions.
Claim 10
Dependent Claim 11 words
The device of claim 1, wherein said elongated member comprises steel.
Claim 11
Dependent Claim 11 words
The device of claim 1, wherein said elongated member comprises titanium.
Claim 12
Dependent Claim 16 words
The device of claim 1, wherein said coated region of said first end portion is gold-colored.
