Abstract
Claims
1. A method for the precise placement of implants, a. A step of performing primary provisional reaming (PP reaming) within the bone to obtain a cavity having a depth corresponding to achieving the maximum range of motion of the joint that demonstrates soft tissue balance, b. A step of establishing a bone reference mark (BRM) corresponding to the length of the stem of the trial in which the maximum range of motion of the joint is achieved, wherein the length of the stem corresponds to the depth of the cavity, c. The step of performing secondary scratching reaming (SS reaming) within the bone cavity with respect to the diameter of the implant until the scratching of the implant is achieved, Methods that include...
2. The method according to claim 1, wherein the step of performing the primary provisional reaming includes reaming the bone cavity using a reamer.
3. The method according to claim 1, wherein the step of establishing the bone reference mark (BRM) includes performing a trial reduction and marking the level of the reamer on an adjacent bone corresponding to the soft tissue balance being achieved.
4. The method according to claim 1, wherein the step of performing the secondary scratch reaming includes further reaming the bone cavity with a reamer to increase the diameter of the bone cavity.
5. The method according to claim 1, wherein the step of performing the secondary scratch reaming includes performing trial reduction using a final trial to achieve scratch fitting.
6. The method according to claim 1, further comprising the step of selecting a definitive implant having dimensions corresponding to the final trial.
7. The method according to claim 1, wherein if an old implant is present in the bone cavity, the method further includes the step of removing the old implant using an implant extractor before the primary provisional reaming.
8. The method according to claim 1, wherein the method comprises a step of primary trialing after the primary preliminary reaming, the primary trialing comprising inserting one or more trials in succession until a trial that is perfectly suitable for the bone cavity is found.
9. An implant system for precise placement of implants, a. One or more trials, b. A reamer comprising a plurality of aligners provided on the body of the reamer, wherein the reamer is configured to perform primary provisional reaming (PP reaming) within the bone to obtain a cavity having a depth corresponding to the maximum range of motion of the joint that shows the soft tissue balance, and the reamer is configured to perform secondary scratching reaming (SS reaming) within the bone cavity relative to the diameter of the implant until scratching of the implant is achieved. c. The aligner establishes a bone reference mark (BRM) corresponding to the length of the stem of one of the one or more trials in which the maximum range of motion of the joint is achieved, and the length of the stem corresponds to the depth of the cavity. Implant system.
