| Objective: Pelvis is an important part of the human body,which is a complex anatomical structure with a lot of vital organs surrounded. Tumor in this region is often bulky, transgression and a broader scope of comparison the incidence of occult, found in many advanced tumors,and it brings the patient with enormous harm of physics and psychology.At the same time, the operations to the pelvic tumor is very difficult,which need Technology high,and many postoperative complications occur after the operations,pelvic tumor is a major problem for bone-science,this article will explore the pelvic tumor's resection, reconstruction and complications through the observion of our hospital's treatment of pelvic tumors .Methods: The retrospect analyses March , 2003 till March , 2008, six patients with an average age of 41.5 year old(17-58 year old) including three males and three females.of which two cases are giant cell tumour of bone, one case is chondrosarcoma, three cases are metastatic tumour.Allotted type method according to Enncking pelvis tumour location: The tumours involved the zones I and II according to Enncking classification in two patients , the zones II and III in two patients, the zones I andâ…£in one patient, the zones I,II and III in one patient. the acetabulum tumour blood-supply arterial was embolismed for three patients ,the patients were treated by sections of plevic tumour and allosome plevic transplantion and steel plate inner.two cases were treated by replacement of artifical articulatio coxae more.One patient was treated by sacral tumor resection after abdominal aortic blocked, one patient was treated by pelvic tumor resection and arthroplasty of a saddling shape of prosthesis, one patient was treated by resection of pelvic tumour and artifical prosthetic replacement. We observe the pelvic healing, quality of life and related complications through the postoperative follow-up of patients.Rezults: bone union occurred fifteen months(range 12 ~ 18 months) in six patients who were followed up ranged from one to five years, there was repulsion occurred in 2 cases in 2 weeks after surgery,and they were recovered by dressing.One case received debridement and untreated femoral head due to infection after deactivation and reimplant of tumor section.there were continuously tumor-free without complications during follow-up.At the final followup.the average functional score was 57.25according to the Harris Postoperative functional evaluation standards, what is whether the physical pain, function, scope of activities carried out score.Conclusions:1.Variant pelvic replacement to the patients with pelvic tumor. are relief of pain can walk independently,the methods also can reduce the morbidity rate,make the rate of allograft fusion pelvis higher,and could be achieved with a high level of patient satisfaction,However, there would be some disadvantage such as wound infection.2. there would be early to reach firm fixed for Shape of saddlding prosthesis and adjustable artificial replacement for the treatment of pelvic tumour, but the metal prosthesis fix to the residual pelvic difficultly and pelvic relaxation, joint dislocation would occur late, At the same time, the metal prosthesis infection rate is also higher.3.embolization treated to the pelvic tumor target Vascular Preoperative and blocking to the abdominal aortic Intraoperative can reduce bleeding, risk of surgery and increase the rate of tumour resection, improving the efficacy of surgical treatment.
