Summary
Postoperative fever after megaprosthesis surgery for bone cancer is common and usually a normal response. Monitor for atypical fever patterns or other symptoms, as these may indicate infection.
Area of Science:
- Orthopedic Oncology
- Surgical Infection Research
Background:
- Early postoperative fever following megaprosthesis replacement surgery raises concerns for orthopedic oncologists regarding potential infection.
- Distinguishing between normal physiological responses and infection-related fever is crucial for patient management.
Purpose of the Study:
- To determine the incidence and patterns of fever after megaprosthesis replacement for lower-extremity osteosarcoma.
- To identify factors associated with fever development.
- To assess the clinical significance of fever in relation to surgical wound infection.
Main Methods:
- Retrospective review of 71 patients undergoing megaprosthesis reconstruction for localized, unoperated lower-extremity osteosarcoma.
- Analysis of postoperative fever (body temperature ≥38 °C) incidence, timing, and resolution.
- Correlation of fever patterns with the occurrence of surgical wound infections.
Main Results:
- Fever occurred in 87.3% of patients within the first two postoperative weeks, with 62% peaking on postoperative day 1.
- The majority (94%) of febrile patients resolved their fever by postoperative day 5.
- No significant association was found between the presence of fever and surgical wound infection (5 infections in 71 patients).
Conclusions:
- Fever within the first five postoperative days is a common and likely physiological response to megaprosthesis replacement for bone sarcomas.
- Atypical fever patterns (e.g., multiple peaks, persistent fever) or accompanying physical findings warrant further investigation for potential infection.
