Experimental study on effect of traditional bone-knitting drugs on traumatic gu bi (bone-rheumatoid lesions)

Traditional bone-knitting drugs (TBKD) are used frequently in the treatment of bone fractures. An animal model of Gu Bi (bone-related rheumatoid lesions) with defects of articular cartilage as the main lesion was developed by surgical trauma under the stereomicroscope in Wistar rats and treated with TBKD. The results showed that TBKD could promote proliferation of cartilage cells around the traumatic site and improve the osteogenetic function in the traumatic state, suggesting that TBKD can be used in combination with other Chinese drugs to treat Gu Bi, including bony lesions of the late-stage rheumatoid arthritis and bony arthritis. But the experimental results also suggested that TBKD might have an effect of promoting development of inflammation, and therefore, should be used with care in the acute phase of inflammation.
