Alterations in Hip Angles Following of Juvenile Pubic Symphysiodesis in Ten Dogs with Hip Dysplasia

Abstract

The purpose of this study is to evaluate of preand postoperative clinical and radiological outcomes of 3-5 month-old, 10 dogs with hip dysplasia after juvenile pubic symphysiodesis. Pain scoring of hip extension test, Ortolani signs and Bardens palpations were performed preand postoperatively, on 1st, 3rd, and 6th months by clinical examinations. Norberg-Olsson angles on standard ventrodorsal on extended radiological views and distraction index on distracted hip radiological views were evaluated by radiological examinations. Juvenile pubic symphysiodesis was applied every 2.0 to 3.0 mm among to the entire length of the growth plate of the pubis via unipolar needle electrocautery (40 W, for 12 to 30 seconds). Acetabular full coverage on the femoral head was provided as a result of ventrolateral rotation of the acetabulum following juvenile pubic symphysiodesis procedure. The hip extension test, Ortolani signs and Bardens palpations were turned from positive to negative. In conclusion, juvenile pubic symphysiodesis is a successful and safe procedure which can be easily applied for prophylaxis and/or treatment of hip dysplasia (HD) in 3-5-month-old, large-breed puppies, which are predisposed to hip dysplasia or showing the initial clinical signs of hip dysplasia.
