Tumour endoprosthetic reconstruction for primary aggressive and malignant bone tumours of the distal femur.

UNLABELLED

At the Philippine General Hospital, tumour endoprostheses have become an option for reconstruction after limb saving surgery for primary bone tumors. We performed a retrospective review of patients with primary bone tumors of the distal femur who underwent tumor excision and reconstruction using tumor endoprostheses. Outcome measures included prosthetic survival, functional outcome and complications. Twenty-two patients were evaluated; 14 males and 8 females, with a mean age of 18 years and a mean follow-up of 56 months. The overall 2-year endoprosthetic survival rate was 86%. Mean MSTS was 23/30. There were a total of 6 revisions. Failure modes included 3 infections, 3 aseptic loosening, 4 structural failures, 2 soft tissue failures and 3 tumor progression. Our early results show that tumor endoprosthesis reconstruction is an acceptable option for patients with primary bone tumor of the distal femur. Survival rates, failure modes and functional outcomes are comparable to other reported studies.
