Objective To explore the use of femoral medullary core decompression with calcium carbonate artificial bone implantation for the treatment of ischemic necrosis of femoral head. Methods In May 2010 to June 2013, the thigh bone marrow core decompression for the treatment of bone graft Ficat Ⅰ - Ⅲ options were 42 patients with ischemic necrosis of bone;Age 27-57,preoperative pain 6 to 18 months, an average of 10 months. All of the patients in the preoperative and postoperative 3 months and 6 months Harris score, and dual hip X-ray and CT examination. Results All patients were followed up for 6 to 36 months, an average of 18 months. Harris score at 3 months, 6 months after operation compared with preoperative rise sharply(P<0.01).After 3 months and 6 months the clinical curative effect of preoperative significantly improved, P<0.01; And the clinical curative effect of postoperative 6 months was superior to that of postoperative 3 months, P<0.05. Patients with postoperative 3 months and 6 months after the imaging stability factor of the preoperative improved significantly, P<0.01; And 6 months after imaging stability factor significantly better than 3 months postoperatively, P<0.05.6 months postoperatively, 37 cases of patients with X-ray shows hip keep basic form, no obvious necrosis, CT showed necrosis area, different degree of repair, 3 cases of single hip symptoms worsen, 1 case of postoperative march showed femoral head necrosis is aggravating, choose operation, 1 case of femoral neck fracture caused by trauma after bone choice after surgery. Conclusions Marrow core decompression plus calcium sulphate artificial femoral head bone implantation treatment of ischemic necrosis of femoral head with a small surgical injury, quicker recovery of joint function, relieve clinical symptoms, the advantages of the short-term effect is satisfied, curative effect is worth looking forward to for a long time.
