Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Hand Surgery

Background:

  • Silicone implants for carpal bones historically faced issues with wear particles.
  • Titanium implants were designed as alternatives to silicone, addressing wear concerns.
  • These implants function as articulating spacers in carpal bone reconstruction.

Purpose of the Study:

  • To introduce and evaluate the clinical efficacy of titanium carpal bone implants.
  • To assess the long-term outcomes of titanium implants in scaphoid, lunate, and trapeziometacarpal joints.

Main Methods:

  • Development of titanium implants with modifications for stability and material properties.
  • Surgical application of these implants starting in 1985.
  • 10-year clinical follow-up and assessment of outcomes.

Main Results:

  • Titanium implants demonstrated promising results over a 10-year period.
  • Implants provided carpal stabilization, functional mobility, strength, and pain relief.
  • Design modifications accommodated titanium properties and enhanced stability.

Conclusions:

  • Titanium carpal bone implants represent a successful alternative to silicone, mitigating wear particle problems.
  • The 10-year clinical experience indicates significant potential for these implants in hand surgery.
  • These implants offer a viable solution for carpal bone defects, improving patient function and comfort.
