X ray and CT imaging in the diagnosis of the application of the ischemic necrosis of femoral head / 中国医学装备

Objective:To investigate the diagnosis value of the X-ray and CT imaging, in the ischemic necrosis of femoral head.Methods: Seventy cases of patients with ischemic necrosis of femoral head were given X ray examination and CT examination, comparing two test results of two methods of inspection.Results: The result of statistical analysis, the rate of X-ray examination was 55.7%, the rate of CT examination was 81.4%. By chisquare test, CT examination compared with X-ray had significant difference (x2=1.389,P<0.05).Conclusion: Compared with X-rays, the sensitivity of CT examination in early diagnosis of avascular necrosis is high; CT examination is an effective method in early diagnosis of ischemic necrosis of femoral head.

Interventional Therapy of Ischemic Necrosis of Femoral Head by Continuative Administration of Medicines through Indwelling Catheter in Artery / 实用放射学杂志

Objective To study the curative effect of ischemic necrosis of femoral head(III ,IV stage)by continuative administration of medicine through indwelling catheter in artery.Methods Thrombolysis in 19 cases with ischemic necrosis of femoral head(III,IV stage) were treated with continuative administration of medicines through indwelling catheter in lateral femoral circumflex and medial femoral circumflex artery and obturator arteriae using Seldinger technique.Results All patients were followed-up for 6～12 months.The curative effect was evaluated by angiography,the clinical symptoms and the change of bone.The ratio of the improvement of clinical symptoms was 75.8%,63% of the necrotic area of femoral head showed hyperplasia.Conclusion By continuative administration of medicine through indwelling catheter in artery in treating ischemic necrosis of femoral head (III ,IV stage) has remarkable therapeutic effect.

The Application of Intramedullary Decompression and Pressor Infusion for ischemic Necrosis of Adult Femoral Head / 实用放射学杂志

Objective To observe the curative effect of adult ischemic necrosis of femoral head by intramedullary decompression and arterial pulse pressor infusion.Methods 82 patients with ischemic necrosis of femoral head were treated in the combined treatment of percutaneous intramedully decompression and pulse pressor five medicine combined infusion in target vessels using ZC-Ⅰ-discome.Results By follow-up for 12～48 months,the painful in hip joint was alleviated and joint movement was also improved.The regenerative vessels and bone in femoral head and neek were obvious.Conclusion This therapcutic methods is safe and superior to single interventional medicine treatment for ischemic necrosis of femoral head.
