Abstract:
Objective To investigate technique and indications of proximal femoral autograft for pelvic reconstruction after tumor resection.Methods Between October 2006 and May 2011,5 patients with primary malignant pelvic tumor underwent tumor resection,pelvic reconstruction by proximal femoral autograft,and hip reconstruction by tumor prosthesis.There were 3 males and 2 females,aged from 19 to 55years (average,30.6 years).There were 3 cases of chondrosarcoma and 2 cases of primitive neuroectodermal tumor (PNET).The tumor involved zone Ⅰ and zone Ⅱ in 3 cases,and zone Ⅱ and zone Ⅲ in other 2cases.All 5 patients were followed up,and complications,MSTS (Musculoskeletal Tumour Society) score and prognosis were recorded.Results At final follow-up,one patient died of pulmonary metastasis,one patient survived with local recurrence,and other 3 patients survived without recurrence.The complications consisted of local recurrence,prosthesis loosening,nonunion,infection,and sciatic nerve palsy.One patient underwent revision surgery for prosthesis loosening 26 months after the initial operation.One patient underwent amputation for local recurrence 6 months after the initial operation.The average MSTS score was 19.2.Conclusion Proximal femoral autograft is an effective method for pelvic reconstruction after tumor resection,which can be used for defect in zone Ⅱ and zone Ⅲ,as well as in zone Ⅰ and zone Ⅱ.However,the method has a high rate of complications.The short-term result is similar to that of pelvic prosthesis,while the long-term result needs further observation.
