Disclosed is a method for limiting diffusion of wear debris of an in vivo implant and an in vivo implant apparatus with a function of limiting wear debris. According to the present invention, an elastomer seal is arranged at a wearing part between implant components that can move relatively and generate wear, such that an outlet for wear debris of the implant is always sealed within a sealing area formed by the seal and the implant components, thereby preventing the wear debris from diffusing outwards. The elastomer seal includes at least one flexible buffer part for reducing or completely offsetting relative motion between the implant components, thereby further reducing wear of a sealing part of the elastomer seal due to the relative motion between the parts. According to the present invention, the seal is tightly attached to in vivo implant components, such that the wear debris cannot escape, and a friction force between the seal and the in vivo implant is smaller than a force for driving the components to generate relative motion, such that the relative motion between the components may not be blocked, thereby solving the problem of wear debris escaping.

Systems, methods and apparatuses including an insert having a body with a plurality of bladders therein, a proximal surface and a distal surface. Two or more of the plurality of bladders are in fluid communication with one another. The plurality of bladders are expandable and contractible in volume. The proximal surface shapable by a change in the volume of one or more of the plurality of bladders. The proximal surface is configured to interface with a first arthroplasty implant of the patient. The distal surface is spaced from the proximal surface by the body and is configured to interface with a second arthroplasty implant of the patient.
