Abstract
|
|
|
Purpose : This study evaluated the oncological and functional results of a surgical treatment for malignant pelvic bone tumors using a low-heat-treated autologous bone graft.
Materials and Methods : Eleven patients with malignant pelvic bone tumors who were followed-upfor more than one year were enrolled in this study. There were six males and five females. The mean age was forty-one years and the mean follow-up period was thirty months. Nine patients had primary bone tumors and two patients had metastatic tumors with various histological origins. A surgical resection was carried out according to the anatomic location (Type I/II 3 cases, Type II 2 cases, Type II/III 6 cases). The surgical methods used were a wide resection, a low-heat- reated autologous bone graft, total hip arthroplasty and rigid internal fixation. The ISOLS score was used to determine the oncological outcome.
Results : The mean ISOLS score was 61.2% at the final follow-up. The index of pain and emotional acceptance showed high scores, but functional ability, support, walking ability and gait showed relatively low scores. Bone union was achieved at a mean post-operative 6 months. The post-operative complications were one case of a local recurrence, two cases of infection and one case of a dislocation of the total hip arthroplasty.
Conclusion : A wide resection and reconstruction with a low-heat-treated autologous bone graft in malignant pelvic bone tumors were satisfactory oncologically as well as functionally in the brief period. However, a longer follow-up and an examination of more cases will be needed.
