Bone plate suture anchor
View Patent ↗A suture anchor insert comprising a body configured to be inserted into a hole in a bone plate. The body has a proximal end, a distal end, a length extending between the proximal and distal ends and substantially corresponding to a thickness of a bone plate, a sidewall, at least one plate engaging member extending outwardly from the sidewall to secure the body to the bone plate, a recess defined by the sidewall, and a transverse edge formed on the sidewall. A crossbar extends inwardly from the sidewall across the recess such that a free end of the crossbar is normally disposed distally of the transverse edge. The crossbar is flexible such that when a distally directed force is applied, the free end of the crossbar is positionable in the recess. The free end of the crossbar is engageable with the transverse edge to limit proximal motion of the crossbar.
1. A suture anchor insert, comprising:
a body configured to be slidably inserted into a hole in a bone plate, the body having a proximal end, a distal end, a length extending between the proximal end and the distal end and so dimensioned as to substantially correspond to a thickness of the bone plate, a sidewall, a recess defined by the sidewall, and a transverse edge formed on the sidewall, the proximal end of the body terminating in at least one lip extending outwardly from the sidewall to be engageable with an upper surface of the bone plate to secure the body to the bone plate; and
a crossbar extending inwardly from the sidewall across the recess such that a free end of the crossbar is normally disposed distally of the transverse edge of the body, the crossbar being flexible such that when a distally directed force is applied to the crossbar, the free end of the crossbar is positionable in the recess and when a proximally directed force is applied to the crossbar, the free end of the crossbar is engageable with the transverse edge to limit proximal motion of the crossbar,
wherein the body has at least one slot formed within the sidewall and wherein the distal end of the body terminates in a second lip extending outwardly from the sidewall to be engageable with a lower surface of the bone plate.
2. The suture anchor insert of claim 1 , wherein the slot extends from the distal end toward the proximal end.
3. The suture anchor insert of claim 2 , wherein the body has a pair of diametrically opposed slots, each slot extending from the distal end toward the proximal end.
4. The suture anchor insert of claim 1 , wherein the body is moveable between a compressed position wherein the body is slidable into the hole of the bone plate, and an expanded position wherein the body is secured within the hole in the bone plate.
5. The suture anchor insert of claim 4 , wherein the body has a crossbar window, the crossbar window having a proximal end forming the transverse edge of the body, and wherein the crossbar is normally disposed in the crossbar window such that when the body is in the compressed position, the crossbar is moveable within the crossbar window without limiting compression of the body.
6. The suture anchor insert of claim 1 , wherein the second lip is curved to facilitate slidably inserting the body into the bone plate.
7. The suture anchor insert of claim 1 , wherein the body has a helical thread extending outwardly from the sidewall between the proximal end and the distal end.
8. The suture anchor insert of claim 7 , wherein the proximal end of the body is configured to engageably receive a driver.
