Three dogs were admitted for repair of bone fracture. Case 1 (Maltese, 1.8 kg, intact female, 5-month-old)and case 2 (poodle, 3.0 kg, intact female, 6-month-old) had non-weight bearing lameness in the left pelvic limb, andcase 3 (mixed, 3.3 kg, intact female, age unknown) had non-weight-bearing lameness in the left thoracic limb. Onorthopedic examination, there was pain, crepitus, palpable instability and substantial soft tissue swelling on the affectedside. No neurological deficits were identified. Radiographs revealed left proximal metaphyseal tibial and fibular fracturesin cases 1 and 2, and left proximal metaphyseal radial and ulnar fractures in case 3. All cases had closed long-bonefractures with short juxta-articular fracture segments. Under fluoroscopic guidance, proper placement of the ring fixationelements was confirmed during surgery. Two or three rings were used to stabilize fractures with traditional circularexternal skeletal fixators (CESF). Postoperative radiographs showed acceptable alignment and apposition of thepreviously identified fracture. Time to radiographic union ranged from 5 to 14 weeks and there were no signs ofimplant failure or pin tract infection. Functional outcomes were excellent in all cases. CESF can be successfully usedto reduce short juxta-articular fractures in which bone plates or external skeletal fixation cannot be applied.
