摘要
目的探析MRI测量骨肉瘤侵袭髓腔范围的作用和确定合理截骨平面的准确性。方法入选30例行保肢术的骨肉瘤患者,术前均行X线片及MRI检查,术后肉眼观察肿瘤标本的肿瘤髓腔内范围,术中行骨髓组织取材,于术后同肿瘤标本同行病理学检查,判断微观范围。术后评价患者肢体功能。结果患者平均功能恢复率是81%,X线片测得的侵袭范围显著小于病理检查(P<0.05),而MRI测得的侵袭范围与病理检查相近,无显著差异。结论采用MRI诊断骨肉瘤的髓腔内侵袭范围准确性高,以此作为手术参考可靠性高,短期随访表明,以髓腔内边界外30mm作为截骨平面安全有效。
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 MRI 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 ~/00 ,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.
