Experimental study of hormone induced ischemic femoral head necrosis treated with ultrashort wave in early stage / 中华物理医学与康复杂志

ABSTRACT

Objective To observe the effectiveness of early intervention with ultrashort wave diathermy in the treatment of experimental avascular necrosis of femoral head (ANFH). Methods Thirty New Zealand white rabbits were divided into three groupsa normal group(group A),a model group(group B) and an ultrashort wave diathermy group(group C). The animals in groups B and C were subject to injection of horse blood serum and methyl prednisolone to induce ANFH, while those in group A were administered with injection of normal saline. The TXA 2, PGI 2, TG, TCh and hemorrheological indice were tested with all the rats. Results The animals in the model group were found with ANFH manifesting avasular necrosis of femoral head bone cells, decrease of bone marrow cells, high blood viscosity and imbalance of TXA 2 PGI 2. The ultrashort wave diathermy group demonstrated significant improvement with regard to the blood supply, the TG level and blood viscosity,as well as the PLT activity and the TXA 2 PGI 2 ratio. Conclusion The ultrashort wave diathermy could be an effective treatment method for preventing ANTH when used in the early stage of development of the condition.
