Summary
Modular endoprosthesis reconstruction for bone tumors shows promising results, particularly for distal femur cases. However, caution is advised for proximal tibia and femur reconstructions due to potential complications and poorer functional outcomes.
Area of Science:
- Orthopedic Surgery
- Oncology
- Biomedical Engineering
Background:
- Bone tumors present significant challenges in limb salvage surgery.
- Modular endoprosthetic reconstruction is an option for replacing resected bone segments.
Purpose of the Study:
- To evaluate the functional outcomes and survival rates of patients undergoing resection of bone tumors and reconstruction with Kotz modular endoprostheses.
Main Methods:
- Retrospective analysis of 33 patients treated with Kotz modular endoprosthesis after bone tumor resection.
- Follow-up averaged 50 months, assessing tumor recurrence, metastasis, and functional results.
Main Results:
- Overall survival was impacted, with 36% mortality and 27% metastasis at follow-up.
- Distal femur reconstructions (17/22) yielded excellent or good functional results.
- Proximal tibia and proximal femur reconstructions showed poor functional outcomes (4/4 and poor/fair for 4/6, respectively).
Conclusions:
- Kotz modular endoprosthetic reconstruction is effective for distal femur bone tumors.
- Its application in proximal tibia and proximal femur bone tumors requires careful consideration due to higher complication rates and poorer functional results.
