目的探讨环锯在骨骼病变活检与治疗中的应用价值。方法 2007~2009年采用环锯法取病变骨组织23例,其中四肢骨19例,髂骨4例,借助术中透视机定位,并用环锯通过皮肤小切口建立工作通道,钻开病变处骨质,取出病变组织送检。结果患者全部活检成功并得到明确病理诊断,23例中,骨脓肿2例,骨肉瘤6例,软骨肉瘤2例,转移性骨肿瘤5例,非骨化性纤维瘤2例,骨纤维异样增殖症2例,骨样骨瘤2例,软骨母细胞瘤2例。无病理性骨折等并发症发生。结论环锯法通道活检术具有类似开放活检获取成形病变组织块的优点,活检阳性率、病检确诊率高,值得在临床进一步推广应用。 Objective To investigate the application value of band saw in biopsy and treatment of skeletal diseases. Methods From 2007 to 2009, 23 cases of diseased bone tissue were obtained by ring saw method, including 19 cases of limbs and 4 cases of ilium. Through the intraoperative fluoroscopy, a working channel was established through the skin incision with a ring saw, and the lesion bone was drilled Quality, remove the diseased tissue for inspection. Results All patients were successfully biopsied and confirmed by pathology. Of the 23 cases, 2 were bone abscess, 6 were osteosarcoma, 2 were chondrosarcoma, 5 were metastatic bone tumors, 2 were non-ossifying fibroma, 2 cases of osteoarthritis, 2 cases of osteoid osteoma, 2 cases of chondroblastoma. No pathological fracture and other complications occurred. Conclusions The method of ring saw biopsy has the advantages of open biopsy to obtain the lesion tissue, the positive rate of biopsy and the high rate of pathological examination, which is worth further popularizing and applying in clinic.
