[Clinical value of B ultrasonography in the diagnosis of transient synovitis of hip in dogs].

OBJECTIVE

To investigate the value of B ultrasonography in the early diagnosis of transient synovitis of hip (TSH) in dogs, and provide the valid base and data for the clinic early diagnosis of TSH.

METHODS

Eighty 2-3 month old dogs were injected 0.2% noradrenalin (NA) into the hip joint induced TSH. We observed 5 assessments that included the 99mTC-MDP triphasic imaging, X ray, B ultrasonography, the synovial fluid and the pathological tissue check in different time.

RESULTS

Early course of TSH presented the synovium of joint hemangiectasis, hyperaemia, synovium villus hyperplasia, edema, and joint inflammatory exudation. The ischemia of local blood supply of the femoral head was observed by 99mTC-MDP triphasic imaging. Ultrasonography showed the broadening of the anterior space of the hip, but the X ray showed no valid changes.

CONCLUSION

B ultrasonography can report the early changes of TSH and may be used in the early diagnosis of TSH in children.
