Biological reconstruction after resection of bone tumors of the proximal tibia using allograft shell and intramedullary free vascularized fibular graft: long-term results.
Reconstruction after excision of bone tumor of the proximal tibia is a challenging issue for the reconstructive surgeon. The combined use of a free fibular flap and allograft can provide a reliable reconstructive option in this location. This article describes the authors' long-term follow-up using this technique. Twenty-seven patients that had resection of proximal tibia bone tumors underwent reconstruction using this technique. Only 21 patients that had primary reconstruction were included in this study. All patients had their surgeries performed at least 24 months before the end of the study. The average age at time of operation was 18.1 years. The average follow-up time was 139.3 months. Limb salvage was 82.7%. The average length of the resected tibial segment was 15.3 cm and that of the residual proximal tibia remaining after resection was 2.7 cm. The average time of union of fibula was 5.4 months and for union of allograft was 19.1 months. Primary union of the allograft was achieved in 90.5% of cases. Full weight-bearing was achieved at an average of 21.6 months. Ten patients (47.6%) had 14 local complications. The (MTSRS) average score at final follow-up was 27.3. Local recurrences occurred in two patients (9.5%). Distant metastasis to the lung occurred in three patients (14.3%). One patient died of disease. This technique provides good long-term results in reconstruction of proximal tibia. The viability of the fibula is a cornerstone in both success of reconstruction as well as successful management of complications.
