Abstract: Radius curvus is a clinical manifestation of the premature closure of the distal ulnar physis and the mostcommon physeal disease in dogs, representing 63% of all physeal injuries. There are few reports indicating the techniqueof stapling for treatment of radius curvus in squeletically immature dogs. The aim of this study is to report a case of radiuscurvus in a young dog successfully treated with a combination of 3 surgical tecniques 1- Stapling the medial and cranialportions of the distal radial physis; 2- Oblique osteotomy of the proximal ulna and ostectomy of the distal ulna, and 3-Dynamic external skeletal fixation in the elbow joint.Case A 5-month-old female dog was referred to the University Veterinary Hospital with a history of left thoracic limb deformity for 2 months. There was a history of possible traumatic event on the front limb, in addition to providing nutritionalsupplements daily. In the radiographic evaluation the changes were identified in the left thoracic limb shortening of theulna, procurvatum and medial angulation of the distal radius, increased joint space and articular incongruity of the elbowjoint. The dog was subjected to surgical treatment by the combination of three main surgical techniques. For the staplingof the distal radial physis the surgical approach on the cranial-medial surface of the distal radius was made. Two surgicalstaples were positioned in the distal radial physis. Thereafter a caudal approach was made to the distal region of the ulnardiaphysis for the distal ostectomy of the ulna. A bone segment of 1 cm in length of the distal ulnar diaphysis was removed.Another caudal approach was made to the proximal region of the ulnar diaphysis and a proximal oblique osteotomy of theulna was performed. For the dynamic external skeletal fixation in the elbow joint two Steinmann pins were inserted. Thefirst pin was proximal to the supracondilar...(AU)
