Abstract: Objective To analyze MRI in measurement of osteosarcoma invasion medullary cavity function and determine the reasonable range of the accuracy of bone cutting plane .Methods Selected 30 osteosarcoma patients with limb-salvage surgery ,X-ray and M RI in preoperative ,postoperative naked eye tumor specimens scope of intramedullary tumor ,intraoperative bone marrow derived ,postoperative histopathological examination with tumor specimens counterparts to determine the micro range .Postoperative evaluated limb function of patients .Results The average rate of functional recovery in patients was 81% ,the range measured by X-ray was significantly less than the pathologic examination(P<0 .05) ,while MRI measured attack range similar to pathological ex-amination ,there was no significant difference .Conclusion The accuracy of scope of medullary cavity osteosarcoma invasion diag-nosed by MRI is high ,as the operation reference high reliability ,short-term follow-up showed that in intramedullary outside the boundary of a 30 mm as bone cutting plane is safe and effective .
