AI Technical Summary

Technical Problem

Conventional acetabular prostheses for hip arthroplasty often lead to post-operative wear and tear, pain, and the need for revision surgeries due to poor anatomical fitness, high invasiveness, and prolonged operation times.

Method used

A modular acetabular prosthesis system comprising a plurality of modules, each with both shell and augmentation components, that are appositionally fixed to the pelvis bone, forming a mating interface to reconstruct the acetabulum and augment the pelvis bone, thereby reducing operation time and invasiveness.

Benefits of technology

The modular system significantly reduces operation time and invasiveness, enhances anatomical fitness, and minimizes the need for revision surgeries by allowing precise and quick assembly of the prosthesis during surgery.

Abstract

Aspects in accordance with the present invention pertain to a prosthesis system comprising a plurality of modules, each of said modules being adapted for separate and appositional fixation thereof to a defective pelvis bone, such that when all the modules have been fixed to the pelvis bone, the modules communicate by a mating interface, thereby forming an acetabular prosthesis that is adapted to reconstruct an acetabulum and / or to augment the pelvis bone.
