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.
