Limb salvage surgery for bone tumors offers a high success rate (91%) and good functional outcomes, comparable to amputation. While complications occur, prosthetic reconstruction provides patients with independence and improved mobility.

Area of Science:

  • Orthopedic Surgery
  • Oncology
  • Biomedical Engineering

Background:

  • Limb salvage surgery is the standard of care for musculoskeletal tumors, offering survival rates similar to amputation.
  • Reconstruction of large bone defects after tumor resection presents significant challenges.

Purpose of the Study:

  • To evaluate the efficacy of limb salvage reconstruction using custom or modular metal implants for large segmental bone defects.
  • To assess local recurrence, complications, and functional outcomes in patients with primary and metastatic bone tumors.

Main Methods:

  • Retrospective analysis of 32 patients who underwent limb salvage reconstruction with metal implants between 1985 and 1995.
  • Data collection included tumor type, location, recurrence, complications, functional status, and survival.

Main Results:

  • A high limb salvage rate of 91% was achieved.
  • Complications occurred in 28% of patients, but prosthetic failure requiring amputation was rare (3 patients).
  • Most surviving patients achieved independence with or without assistive devices, with no aseptic loosening or implant breakage in long-term follow-up (≥2 years).

Conclusions:

  • Limb salvage reconstruction with metal implants provides favorable functional outcomes and an acceptable complication rate for large segmental bone defects.
  • This approach offers patients a better functional result and more energy-efficient gait compared to amputation.
