Bone plate system with inserts for contacting an adjacent bone surface
The disclosure relates to a bone plate systems and method. A system comprises a bone plate having a bone facing side, a front side being arranged substantially opposite to and facing away from the bone facing side, and at least one insert receiving portion, the system further comprising at least one insert defining a contacting region for contacting an adjacent bone surface and being releasably receivable in said insert receiving portion, wherein the insert is insertable into the insert receiving portion from the bone facing side.
1. A bone plate system, comprising:
a bone plate having a bone facing side, a front side arranged substantially opposite to and facing away from the bone facing side, and an insert receiving portion; and
an insert defining a contact region for contacting an adjacent bone surface of a bone and being releasably receivable in the insert receiving portion,
wherein the insert is insertable into the insert receiving portion from the bone facing side, and
wherein the contact region is configured for interlocking with the bone such that the insert remains in contact with the bone when secured to the bone and separated from the bone plate.
2. The bone plate system of claim 1 , wherein the insert comprises a release portion accessible from the front side of the bone plate.
3. The bone plate system of claim 1 , further comprising:
a fixing member receiving portion configured to receive a fixing member for securing the bone plate to a bone, the fixing member receiving portion and the insert receiving portion being at least partially separated from one another.
4. The bone plate system of claim 1 , wherein the insert further comprises a fixing member receiving portion configured to receive a fixing member for securing the bone plate to a bone.
5. The bone plate system of claim 1 , wherein the insert receiving portion comprises a recess that is connected to the front side.
6. The bone plate system of claim 1 , wherein the insert is configured to engage the insert receiving portion.
7. The bone plate system of claim 6 , wherein the insert comprises a stop portion configured to abut against the insert receiving portion so as to limit an insertion depth of the insert.
8. The bone plate system of claim 1 , wherein at least one of the insert and insert receiving portion comprises a locking portion for being lockable with the respective other of the insert and insert receiving portion.
9. The bone plate system of claim 8 , wherein the locking portion comprises a snap-fit portion.
10. The bone plate system of claim 1 , wherein the contact region is configured to extend beyond an adjacent portion of the bone facing side towards an adjacent bone surface.
11. The bone plate system of claim 1 , wherein the contact region is configured to be flush with an adjacent portion of the bone facing side.
12. The bone plate system of claim 1 , wherein the contact region is larger than the insert receiving portion.
13. The bone plate system of claim 1 , wherein the contact region comprises a plurality of protruding members arranged to protrude towards an adjacent bone surface.
14. The bone plate system of claim 13 , wherein the protruding members comprise spikes.
15. The bone plate system of claim 1 , wherein the contact region comprises a bone ingrowth portion.
16. The bone plate system of claim 1 , wherein the contact region comprises a porous material.
17. A bone plate system, comprising: a bone plate having a bone facing side, a front side arranged substantially opposite to and facing away from the bone facing side, and an insert receiving portion; and an insert defining a contact region and a release portion, the contact region for contacting an adjacent bone surface and the release portion being releasably receivable in the insert receiving portion, wherein the insert is insertable into the insert receiving portion from the bone facing side, and wherein the insert includes at least one deflectable operating portion that in a first position inhibits removal of the insert from the insert receiving portion of the bone plate and in a second position allows removal of the insert from the insert receiving portion; and wherein the contact region is configured for interlocking with the bone such that the insert remains in contact with the bone when secured to the bone and separated from the bone plate.
18. The bone plate system of claim 17 , wherein the release portion is accessible from the front side of the bone plate.
19. The bone plate system of claim 1 , further comprising:
a fixing member receiving portion configured to receive a fixing member for securing the bone plate to a bone, the fixing member receiving portion and the insert receiving portion being at least partially separated from one another.
20. A method of operating a bone plate system comprising a bone plate and an insert, the bone plate having a bone facing side, a front side being arranged substantially opposite to and facing away from the bone facing side, and an insert receiving portion, the insert defining a contact region for contacting an adjacent bone surface of a bone and being releasably receivable in the insert receiving portion, the method comprising the steps of:
arranging the bone plate such that the contact region of the insert releasably receivable in the insert receiving portion abuts against the adjacent bone surface of the bone;
securing the bone plate to the bone by way of at least one fixing member; and
removing the at least one fixing member and releasing the insert from the insert receiving portion of the bone plate such that the bone plate can be removed from the bone while the insert remains in contact with the adjacent bone surface of the bone.
21. A bone plate system, comprising: a bone plate having a bone facing side, a front side being arranged substantially opposite to and facing away from the bone facing side, and an insert receiving portion; and an insert defining a contact region for contacting an adjacent bone surface and being releasably receivable in the insert receiving portion, wherein the insert is insertable into the insert receiving portion from the bone facing side, and wherein the contact region is configured to be substantially parallel to the bone facing side and to exceed a largest cross-section of the insert receiving portion; and wherein the contact region is configured for interlocking with the bone such that the insert remains in contact with the bone when secured to the bone and separated from the bone plate.
