螺旋CT对复杂骨关节损伤的诊断价值

目的 :探讨螺旋CT对复杂骨关节损伤的诊断价值。方法 :采用回顾性方法 ,对 5 0例复杂骨关节损伤病人CT片进行分析。其中 31例同时做了X线平片和CT检查。将CT片与平片结果进行对照研究。结果 :5 0例病人 ,CT显示骨折 15 2处 ,关节脱位 2 5个 ,椎管狭窄 13例 ,脊髓损伤 12例 ,蛛网膜下腔出血 1例 ,胸水 4例 ,关节积液 6例 ,上颌窦积血 6处 ,鼓窦、乳突积血 4处 ,软组织损伤 10例。31例中CT显示骨折10 4处 ,平片显示 46处 ;CT显示关节损伤 2 1个 ,平片显示 9个 ;CT显示椎管狭窄 10例 ,脊髓损伤 9例 ,关节积液 5例 ,平片均未显示 ;CT显示椎弓畸形 1例、平片诊断椎弓骨折可能 ,经手术证实为畸形 ;股骨粗隆间骨折 1例 ,CT、平片均未显示。结论 :(1)螺旋CT能直观、准确判定骨折类型 ,骨折片大小、数目及位置 ;(2 )能充分显示骨折片移位对附近组织造成的损伤情况 ;(3)能充分显示关节损伤程度并判定其稳定性 ;(4 )对损伤骨关节周围的软组织改变显示清晰 ,对复杂骨关节损伤有很高的诊断价值 ,但对线性骨折显示欠佳 ,可造成漏诊 ,应采取其它检查方法避免

Diagnosis Worth of Spiral CT for Complex Bone Joint Damage

Objective: To discuss the worth of spiral CT for the diagnosis of complex bone joint damage. Method: 50 patients with complex bone joint damage were examined with CT. Among them 31 patients were examined with X-ray flat inspection. The results of the two examinations were compared and analysed. Results: The CT inspections of the 50 patients showed 152 fracture places, 25 joint dislocations, 13 spinal stenosis, 12 damage of spinal cord, 1 subarachnoid hemorrhage, 4 pleural effusion, 6 joint product liquid, 6 maxillaris sinus amass blood, 4 drum sinus and milk amass blood and 10 swelling of soft tissue. The CT inspections of the 31 patients who were examined with X-ray inspection showed 104 fracture places and X-ray flats 46 places. About joint damage CT showed 21 places and X-ray flats 9 places. 10 cases spinsl stenosis, 9 cases damage of spinal cord and 5 cases joint product liquid were sbowed on the CT but weren't showed on the X-ray flats. Conclusion: (1) Spiral CT can accuratly show fracture type, fracture flat size, number location. (2) Spiral CT can show fully the damage of nearby tissue caused by the fracture flat shift. (3) Spiral CT can show that joint damage level and the stability canbe judged. (4) Spiral CT can show the change of nearby soft tissne of the injured bone joint distinctly. Spiral CT has very high diagnosis value on the complex bone joint damage.
