目的探讨与对比骨感染性炎症与骨肿瘤的影像学改变,为以后四肢长骨的骨感染性炎症影像结果和骨肿瘤影像结果提供鉴别参考依据。方法选取2011年2月—2014年2月收治的95例患者作为研究对象,其中47例骨感染患者为骨感染组,48例骨肿瘤患者为骨肿瘤组。对两组患者分别采用X线、CT和MRI进行观察分析,计数资料采用四格表卡方检验进行比较,P<0.05为差异有统计学意义。结果骨感染组骨质破坏累及骨垢的分布率为33.33%,骨干髓腔改变的分布率为29.41%,病变边界清晰可辨的分布率为22.22%,层状连续骨膜新生骨的分布率为90.91%,Codman三角的分布率为20.00%,死骨形成的分布率和髓腔内脓肿的分布率都为100.00%;骨肿瘤组的骨质破坏累及骨垢的分布率为66.67%,骨干髓腔改变的分布率为70.59%,病变边界清晰可辨的分布率为77.78%,层状连续骨膜新生骨的分布率为9.09%,Codman三角的分布率为80.00%,死骨形成的分布率和髓腔内脓肿的分布率都为0,两组比较差异均有统计学意义(均P<0.05)。结论合理利用X线平片、CT和MRI等多种影响学手段对四肢长骨的骨感染性炎症患者和骨肿瘤患者进行检查,充分了解各患者各征象的意义,将有助于两类疾病的鉴别,有效避免误诊。
Objective To investigate and compare the imaging changes of bone inflammation and bone tumor, and to provide evidences for the imaging results of the bone inflammation of long bones in the future. Methods Ninety-five patients admitted to our hospital from February 2011 to February 2014 were selected as the experimental group, including 47 cases of bone infection as bone infection group and 48 cases of bone tumor as bone tumor group. The two groups of patients were observed by X-ray, CT and MRI analysis, count data using four-table chi-square test for comparison, P <0.05 for the difference was statistically significant. Results The distribution rate of bone scale involvement in bone destruction was 33.33% in bone infection group, the distribution rate in medullary cavity was 29.41%, the discernable distribution rate in diseased boundary was 22.22%, and the distribution rate of laminar periosteal new bone was 90.91%, Codman’s triangle distribution rate was 20.00%, the distribution rate of sequestrum and intramedullary abscess distribution rate were 100.00%; bone destruction group involving bone destruction rate of 66.67% of bone scale, bone marrow The distribution rate of cavity change was 70.59%, the discernable distribution rate of lesions was 77.78%, the distribution rate of layered periosteal new bone was 9.09%, the distribution rate of Codman triangle was 80.00%, the distribution rate of senescence and The distribution rate of intramedullary abscess was 0, the difference between the two groups was statistically significant (P <0.05). Conclusion It is reasonable to use X-ray, CT and MRI and other influencing measures to examine the patients with bone-inflamed inflammation of the long bones and the patients with bone tumors. It is of great significance to fully understand the significance of each symptom in each patient, Identification, effectively avoid misdiagnosis.
