Summary
Deep allograft infections after massive bone tumor resections are common, often polymicrobial, and necessitate allograft removal. Soft tissue complications are key risk factors, impacting limb salvage outcomes.
Area of Science:
- Orthopedic Surgery
- Oncology
- Infectious Diseases
Background:
- Massive allograft implantations are used in treating bone tumors.
- Deep infection is a significant complication following allograft procedures.
- Understanding risk factors and outcomes is crucial for patient management.
Purpose of the Study:
- To analyze the incidence, risk factors, and outcomes of deep infections after massive allograft implantations.
- To evaluate the effectiveness of salvage procedures and identify factors influencing limb salvage.
Main Methods:
- Retrospective analysis of 75 massive allograft implantations.
- Review of 10 cases with deep allograft infections.
- Evaluation of outcomes using the revised Mankin classification.
- Statistical analysis (Chi-square) for risk factors like chemotherapy.
Main Results:
- 13.3% of patients developed deep allograft infections, mostly within 1 month post-surgery.
- Polymicrobial infections occurred in 50% of cases.
- Wound and soft tissue complications were major risk factors; chemotherapy was not significant.
- All infected allografts required removal; limb salvage was achieved in 7/10 patients, with 3 requiring amputation.
- Salvage options included vascularized fibula transfers and repeat allograft implantation (which also became infected).
Conclusions:
- Deep infection is a serious complication of massive allografts, often requiring allograft removal.
- Meticulous soft tissue management, including flaps, is critical to prevent infection.
- Outcomes are variable, with a significant need for amputation in some cases.
