Abstract Background The necessity to reconstruct the pelvic ring after an iliac or iliosacral resection is still debated. Different reconstructive techniques are available, including autologous and homologous graft and custom-made prosthesis. The aim of this study was to evaluate the functional outcome and complications of patients who underwent resection of iliac bone and part of the sacrum for primary bone tumour and reconstruction with an allograft or autograft.Methods We retrospectively evaluated 18 patients (10 males and 8 female) with a mean age of 28 years (range 9–56) who were operated between 1992 and 2015. Six patients were reconstructed with an autograft (Group A) and 12 patients with an allograft (Group B). All complications were recorded. At final follow-up, patients with the original reconstruction still in site were functionally evaluated with MSTS Score.ResultsMean follow-up time was 107 months (range 4–221). Two patients (11.1%) had an external hemipelvectomy for local recurrence, and 3 patients died of the disease. Mean MSTS Score was comparable between the two groups 21.7 (range 20–25) in Group A and 19.9 (range 4–28) in Group B. Patients with partial sacral resection had an increased risk of local recurrence and lower MSTS Score [15.5 (range 7–20) vs. 22.2 (range 4–28)].Conclusions Biological reconstruction of pelvic ring with autologous or homologous bone graft gives acceptable functional results. However, the decision on how to reconstruct the pelvic ring after iliac resection should be taken on a patient-by-patient basis.
