摘　　要：目的:分析四肢关节滑膜结核的X线特点,提高对早期四肢关节结核的诊断水平。方法:回顾性分析本院2003年3月-2013年6月经MRI及手术证实的17例四肢关节滑膜结核的MRI及X线片资料,总结四肢关节滑膜结核的X线征象。结果:17例四肢关节滑膜结核中,12例未单关节受累,5例为多关节受累。有显著X线表现者6例,表现为关节囊膨隆,关节囊周围脂肪垫受压缩小,关节周围软组织层次不清。结合MRI表现对应发现X线表现者有9例,其X线主要表现为受累骨皮质毛糙,骨皮质下骨质密度略高,骨质密度减低,未发现骨小梁断裂征象。2例未见明显X线征象。结论:分析和总结关节滑膜结核的X线表现对早期四肢关节滑膜结核的筛选具有重要价值。Objective：To analyze the X-ray features of joint tuberculosis of the limbs,in order to improve the diagnos-tic level in early joint tuberculosis of the limbs.Methods：The X-ray appearances of 17 cases of joint tuberculosis of the limbs diagnosed by MRI and confirmed by operation and pathology in our hospital from March 2003 to June 2013 were analyzed retrospectively.The X-ray findings were summarized.Results：Of the 17 cases of joint tuberculosis,one joint was involved in 12 cases,and two or more joints were involved in 5 cases.6 cases had significant changes on X-ray,which appeared as dis-tension of the joint capsule,fat pad reduction and compression around the joint capsule and unclear boundaries of soft tissue around the joint.Changes on X-ray were found according to the MRI features,which appeared as rough cortical bone,slight-ly increased bone densiy under cortical bone and reduced bone density.Signs of trabecular discontinuity was not found.No obvious changes on X-ray were found in 2 cases.Conclusion：Analyzing and summarizing X-ray findings of limbs synovial tu-berculosis is useful for early diagnosis of the limbs synovial tuberculosis.
