Abstract:
Objective To investigate the clinical efficacy of porous calcium phosphate bioceramics (PTCP)for treating stage FicatⅢ non-traumatic osteonecrosis of the femoral head(ONFH)in the patients aged below 60 years old.Methods A total of 41 patients (63 hips)with non-traumatic ONFH in our hospital from March 2006 to July 2009 were collected and divided into two groups.The group A (n=1 6)was performed the core decompression only,while the group B (n=25)was performed the core de-compression plus through the head-neck junction of the femur to opening the window light bulb shape focus debridement and impac-ting bone grafting combined with PTCP implantation.The various clinical evaluation indicators were observed and evaluated.Results No statistically significant differences in PRI were found at each time point in the group A.PRI at postoperative 1 month in the group B was significantly decreased than before operation,hereafter,the stable status was maintained and slightly risen again until postoperative 3 years(P =0.033).The Harris scores at postoperative all time points in the group A were significantly lower than those in the group B.The necrosis areas at postoperative 24 months,3,4,5 years in the group B were significantly decreased com-pared with before operation and lower than those in the group A.Conclusion PTCP implantation has satisfactory effect for the treatment of stage FicatⅢ non-traumatic ONFH in the patients aged below 60 years old.
