Introduction:

The proximal resection of the tibia with endoprosthetic reconstruction is a complex limb preservation procedure in the presence of tumors of the proximal tibia. Recent advances in implants and surgical techniques have made this option preferable to amputation for many patients. Long-term survival and recurrence rates are similar between limb salvage and limb ablation.

Case report:

A 55-year-old woman with the pain of six months of evolution in the upper third of the left leg to 2 cm below the tibial tuberosity and increased volume in this area, with imaging and biopsy studies, confirmed osteosarcoma, without metastasis; proximal tibial resection and endoprosthetic reconstruction were performed.

Conclusions:

The proximal resection of the tibia with prosthetic reconstruction may be associated with significant complications; however, these can be minimized with proper preoperative planning and meticulous technique.
