Abstract
Abstract A bore is provided in bone, the bore communicating with a slot provided in the bone's cortical layer and with a channel of larger size than the slot located in cancellous bone below the slot. The slot overlays the channel and is in communication therewith. A length of suture is knotted to a size greater than the width of the slot, and the knot is introduced to the channel via the bore. The remainder of the suture is passed through the slot whereby the length of suture is anchored in the bone. Instead of knotting the suture, it can be attached to a bead having a diameter greater than the width of the slot, the bead being received within the channel to again anchor the suture.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
87 words
A method for anchoring suture to bone, comprising: surgically preparing the bone by forming a slot in a cortical layer of the bone which overlays and communicates with a channel formed in a cancellous portion of the bone, the channel having a width greater than the width of the slot; and introducing a length of suture into the channel whereby at least one end of the suture passes through the slot, said suture including a portion within the channel which is retained against passage through the slot.
Claim 2
Independent Claim
87 words
A method for anchoring suture to bone, comprising: surgically preparing the bone by forming a slot in a cortical layer of the bone which overlays and communicates with a channel formed in a cancellous portion of the bone, the channel having a width greater than the width of the slot; and introducing a length of suture into the channel whereby at least one end of the suture passes through the slot, said suture including a portion within the channel which is retained against passage through the slot.
Claim 3
Dependent Claim
30 words
A method according to claim 1, wherein said suture portion is retained by a knot formed in the suture and having a width greater than the width of the slot.
Claim 4
Dependent Claim
29 words
A method according to claim 2, wherein said knot is formed at the opposite end of the suture whereby a single segment of the suture passes through the slot.
Claim 5
Dependent Claim
26 words
A method according to claim 2, wherein said knot is formed intermediate the ends of the suture whereby two segments of suture pass through the slot.
Claim 6
Dependent Claim
22 words
A method according to claim 1, further comprising: forming a bore in the bone which communicates with the slot and the channel.
Claim 7
Dependent Claim
35 words
A method according to claim 5, further comprising: introducing a bead through the bore into the channel, said bead having a width greater than the width of the slot and carrying said length of suture.
Claim 8
Dependent Claim
17 words
A method according to claim 6, wherein said suture extends through a passage formed in the bead.
Claim 9
Dependent Claim
32 words
A method according to claim 7, wherein said bead is joined to the suture intermediate the ends of the length of suture whereby two segments of the suture pass through the slot.
Claim 10
Dependent Claim
23 words
A method according to claim 6, wherein said suture is received and retained within a slot provided on the exterior of the bead.
Claim 11
Dependent Claim
36 words
A method according to claim 9, wherein said bead is joined to the suture intermediate the ends of the length of suture whereby two segments of the suture pass through the slot in the cortical layer.
Claim 12
Dependent Claim
40 words
A method according to claim 5, wherein said suture portion is retained by a knot formed in the suture and having a width greater than the width of the slot, said knot being introduced through the bore into the channel.
Claim 13
Dependent Claim
29 words
A method according to claim 11, wherein said knot is formed at the opposite end of the suture whereby a single segment of the suture passes through the slot.
Claim 14
Dependent Claim
26 words
A method according to claim 11, wherein said knot is formed intermediate the ends of the suture whereby two segments of suture pass through the slot.
