ABSTRACT
[Objective]To explore the change and its significance of the expression of basic fibroblastic growth factor(bFGF) and bone morphogenetic protein-2(BMP-2) of the local femoral head in nontraumatic osteonecrosis(NONFH). [Methods]Thirty samples of femoral heads of NONFH were collected as the experimental group and 10 fresh samples of femoral heads of femoral neck fracture as control group.The specimens were collected at the time of total articular replacement arthroplasty.The bone tissues from necrosis area and healthy area were made into general sections after immobility and decalcification.Pathological changes were exexamined by optical microscopy and the expression of bFGF and BMP-2 in femoral head was determined with in-situ hybridization technique.[Results]The organization structure of experimental group was disorganized,cracked,and the bone trabecula was rarefactive and non-intact.There were a great number of empty lacune in bone trabecula.The intensity and area of positive expression of bFGF and BMP-2 in femoral head of the experimental group were obviously lower than that of control group.The result had statistical significance(P
