This study introduces a novel fibular segment technique for trans-tibial amputations, creating a solid bone bridge (synostosis) between the tibia and fibula. This method enhances distal weight-bearing capacity for amputees using prostheses.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Regenerative Medicine

Background:

  • Trans-tibial amputations often face challenges with stump healing and prosthetic rehabilitation.
  • Conventional techniques may limit distal weight-bearing capabilities.
  • The Ertl procedure, using osteoperiosteal flaps, has been a historical approach.

Purpose of the Study:

  • To present an alternative surgical method for synostosis in trans-tibial amputations.
  • To evaluate the efficacy of using a fibular segment instead of tibial osteoperiosteal flaps.
  • To assess the impact on distal weight-bearing and prosthetic rehabilitation.

Main Methods:

  • A modified technique involving a fibular segment was applied to 15 trans-tibial amputees between May 1997 and February 2003.

  • The procedure aimed to create a synostosis (bone fusion) between the tibia and fibula.
  • Patients were subsequently rehabilitated with prosthetic devices.

    • Main Results:

    • All 15 patients achieved a solid synostosis between the tibia and fibula.
    • Successful prosthetic rehabilitation was reported for all patients.
    • Remarkable distal weight-bearing capacity of the stump was observed compared to conventional methods.

    Conclusions:

    • The fibular segment technique offers a viable and effective alternative for achieving synostosis in trans-tibial amputations.
    • This method significantly improves distal weight-bearing, enhancing prosthetic use and patient outcomes.
    • Further research may explore long-term benefits and broader applications.
