Summary

Custom pelvic implants (CPIs) offer a reliable solution for complex hip revision surgery with severe bone loss. These patient-specific implants provide durable fixation and improved function, demonstrating high survivorship in challenging acetabular reconstructions.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Radiology

Background:

  • Severe acetabular bone loss and pelvic discontinuity pose significant challenges in revision total hip arthroplasty.
  • Standard reconstructive techniques may fail to achieve durable fixation or restore hip biomechanics.

Purpose of the Study:

  • To review the evolution, nomenclature, indications, and design of custom pelvic implants (CPIs).
  • To outline preoperative evaluation, surgical techniques, and outcomes for CPIs in acetabular reconstruction.

Main Methods:

  • Review of literature on CPIs, from early designs to modern porous-coated implants.
  • Discussion of CT-based modeling, implant design considerations, and surgical management of pelvic discontinuity.
  • Analysis of published midterm to long-term outcomes and economic comparisons.

Main Results:

  • CPIs are patient-specific, additively manufactured monoblock constructs designed for maximal fixation.
  • Surgical techniques focus on construct stability and osseointegration, with effective management of pelvic discontinuity.
  • Published outcomes show high implant survivorship, improved function, and low mechanical failure rates, with revisions mainly due to infection or instability.

Conclusions:

  • Custom pelvic implants provide an effective and reproducible strategy for complex acetabular reconstruction.
  • Appropriate patient selection, design collaboration, and surgical execution are crucial for successful CPI application.
  • CPIs are cost-comparable to other advanced options, offering reliable fixation in challenging cases.
