Modular components in total hip arthroplasty offer benefits but pose risks. This study highlights modular neck fractures as a potential complication, necessitating revision surgery even with well-fixed implants.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science

Background:

  • Modularity in total hip arthroplasty (THA) is increasingly adopted.
  • Advantages include enhanced visualization during acetabular revision and improved biomechanics.

Observation:

  • Disadvantages of modularity encompass component dissociation, junctional failure, corrosion, and generation of metal debris.
  • Two cases of modular neck fracture in THA are presented.

Findings:

  • Modular neck fracture is a potential complication of modular total hip arthroplasty.
  • These fractures can necessitate revision surgery despite well-fixed components.

Implications:

  • Highlights the risks associated with modular hip implants.
  • Suggests careful consideration of modular neck design and patient selection.
