A Case of Cranial Tibial Wedge Osteotomy Treatment of Canine Anterior Cruciate Ligament Rupture

Abstract:

A May poodle fell from a high place and the left hind limped.Surgery and rehabilitation were performed based on the results of palpation,blood biochemical and routine tests,tibial compression test,drawer test and Xray examination.The results showed that by palpating the affected knee joint,the dog had pain and resistance,the tibia was shifted forward relative to the femur;blood biochemical and blood routine examination showed no pathological indicators;tibial compression test and knee drawer test were positive;Xray examination showed the affected tibial plateau significantly forward,and tibial plateau angle (TPA) was 25°,and diagnostic result was anterior cruciate ligament rupture.Because the dog was young and in the stage of bone growth and development,and tibial plateau leveling osteotomy (TPLO) easily affected the epiphyseal plate development,so tibial wedge osteotomy (CTWO) was used.On the fifth postoperative day,the affected limbs of the sick dogs can exercise normally;on the 10th postoperative day,the affected limb fully regained its normal function,and the surgical suture was removed;after 2 months,the surgical bone plate was removed,TPA value was measured as 4°,and there were no complications.It indicated that the surgical method has ideal curative effect,and has the advantages of simple operation,high stability and accuracy, which is worthy of clinical promotion and application in pets.
