Abstract
Abstract A locating anchor for a replacement ligament is described. The anchor comprises a bar which is operable to extend across the opening of a bone tunnel through which the replacement ligament passes. The bar has a number of characterising features. The bar may not include any lateral support, the bar may be recessed, the bar may have a fixing groove, preferably, for ligament sutures or fixing means may be provided at each end of the bar to fix the ends of the bar in the bone surrounding the tunnel opening. A method of fixation is also defined. The bar is particularly useful in avoiding hindrance to the surgeon caused by the necessity to thread sutures through the fixation device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
39 words
A locating anchor for a replacement ligament comprising a bar which
is operable to extend across the opening of a bone tunnel through which the
replacement ligament passes characterised in that the bar does not include any
lateral support.
Claim 2
Dependent Claim
39 words
A locating anchor for a replacement ligament as claimed in claim 1,
characterised in that fixing means are provided at each end of the bar to fix
the ends of the bar in the bone surrounding the tunnel opening.
Claim 3
Dependent Claim
41 words
A locating anchor for a replacement ligament as claimed in any
preceding claim, characterised in that the mid portion of the bar is recessed
with respect to its ends so that it may be seated within the end of the tunnel.
Claim 4
Dependent Claim
59 words
A locating anchor for a replacement ligament as claimed in any
preceding claim, characterised in that the locating anchor is recessed in such
a way that the angle of the recessing portion of the bar extending from one
end to the recessed mid portion is substantially equal to the angle between the
surface of the bone and the tunnel.
Claim 5
Dependent Claim
37 words
A locating anchor for a replacement ligament as claimed in any of
claims to 1 to 4, characterised in that the base of the recess is formed to be
substantially perpendicular to the axis of the tunnel.
Claim 6
Independent Claim
53 words
A method of anchoring a replacement ligament comprising the steps of: tying at least one end of the replacement ligament to a locating anchor
comprising a bar which extends across the opening of a bone tunnel through
which the replacement ligament passes characterised in that the bar does not
include any lateral support.
Claim 7
Dependent Claim
67 words
A method of anchoring a ligament as claimed in claim 6, characterised
in that the method includes the step of fixing a locating anchor in accordance
with the first aspect of the present invention at one of the entrances to the
tunnel, characterised in that the method includes the step of typing the
ligament over the locating bar which is fixed at the end of the tunnel.
Claim 8
Dependent Claim
95 words
A locating anchor for a replacement ligament comprising a bar which
is operable to extend across the opening of a bone tunnel through which the
replacement ligament passes characterised in that the mid portion of the bar
is recessed with respect to its ends so that it may be seated within the end of
the tunnel to an extent which allows a knot to be tied thereto and to be wholly
contained within the tunnel characterised in that fixing means are provided to
fix the anchor to the bone prior to tying of the knot.
Claim 9
Dependent Claim
52 words
A locating anchor for a replacement ligament comprising a bar which
is operable to extend across the opening of a bone tunnel through which the
ligament passes characterised in that a locating groove is formed in the bar on
its mid portion to locate the ligament, and thereby to prevent slipping use.
Claim 10
Dependent Claim
55 words
A locating anchor for a replacement ligament comprising a bar which
is operable to extend across the opening of a bone tunnel through which the
ligament passes characterised in that fixing means are provided at each end of
the bar to fixedly secure the ends of the bar in the bone surrounding the
tunnel opening.
