The effect of intramedullary cement on intercalary allograft reconstruction of bone defects after tumour resection: a pilot study.

摘要: OBJECTIVE A pilot study to evaluate the surgical and functional results of resection reconstruction diaphyseal bone tumours with cemented uncemented intercalary allografts. DESIGN retrospective case series. SETTING quaternary care unit within a teaching hospital. PATIENTS Twenty-two patients treated between 1988 1992, mean follow-up 38 months (range from 20 70 months). INTERVENTIONS Diagnostic biopsy in all patients. Preoperative postoperative chemotherapy high-grade sarcoma. En-bloc excision tumours. Reconstruction defect (15 patients) or (7 MAIN OUTCOME MEASURES Nonunion at one both osteosynthesis sites, death systemic disease, amputation. RESULTS Six 22 died disease graft intact, 3 subsequently had amputation for either local recurrence (2 failure free tissue transfer (1 patient), leaving 13 alive allograft situ an average 36 24 64 There were no revision procedures remove replace original allograft.
