Abstract:
Objective To investigate the effeit of Reconstruction of tantalum metal rod implantation in the treatment of early ischemic necrosis of femoral head( Steinberg Ⅰ～Ⅱ period) ,to explore the early femoral head ischemic necrosis of minimally invasive treatme(n)t. Method 24 patients( Steinberg Ⅰ～Ⅱ period) using C-arm fluoroscopy machine,under the greater trochanter through the neck hole to avascular necrosis zone,the first zone of the medullary sclerosis core decompression, re-implantation of tantalum rod to the subchondral bone is about 0.5 cm, through the Harris score before and after surgery for comparison. Results After follow-up 9(2 ～ 12) months,preoperative pain and function were significantly limited nuitigation. The excellent rate was 83% after opertion. MRI manifestations in patients with stable,non-ischemic necrosis increased performance. Conclusion Core decompression can significantly reduce the pressure on the femoral head hardening region, tantalum rod weight-bearing area of femoral head implant provides a structural support for subchondral bone. This method has the characteristics decompression,structural support,minimally invasive,it is worth for clinical use.
