Summary
This study details a limb-salvage technique for proximal tibia tumors using endoprosthetic replacement and a gastrocnemius flap. While effective, it involves a significant complication rate and high revision probability.
Area of Science:
- Orthopedic oncology
- Surgical reconstruction
- Tumor endoprosthetics
Context:
- Limb-salvage surgery is crucial for proximal tibia tumors.
- Reconstruction of the extensor mechanism is a key challenge.
- Modular tumor endoprostheses offer a solution for bone defects.
Purpose:
- To describe a technique for limb-salvage surgery of proximal tibia tumors.
- To detail endoprosthetic replacement and gastrocnemius flap reconstruction.
- To evaluate the outcomes and complications of this procedure.
Summary:
- The technique involves en bloc tumor resection, intra-extra articular knee joint resection, and tibial osteotomy.
- Reconstruction utilizes a modular tumor endoprosthesis with gastrocnemius flap reattachment to the patellar tendon.
- Postoperative management includes drainage, bracing, and controlled weight-bearing.
Impact:
- The procedure achieves limb salvage but has a complication rate exceeding 10%, including infection and nerve palsy.
- Functional outcomes show a mean extension lag of 30°, with a 60-70% revision rate at 10 years.
- Despite challenges, this technically demanding resection is a recommendable procedure for proximal tibia tumors.
