![]() ![]() To facilitate further evaluation, the dog was premedicated with methadone (0.2 mg/kg, SC) and acepromazine maleate (10 μg/kg, SC), and anesthesia was induced with propofol (3 mg/kg, IV) and maintained with isoflurane (1.5%) in oxygen. All other general, neurologic, hematologic, and thoracic radiographic findings were unremarkable. Orthopedic examination revealed non–weight-bearing lameness, muscle atrophy, and loss of typical morphology and alignment of the right pelvic limb as well as signs of pain on palpation of the right tibia. Sterile nonadherent gauze was placed over the wound to prevent possible further contamination and secured with light bandaging. Physical examination revealed a 2-cm skin wound on the right pelvic limb over the craniomedial aspect of the midtibial region. The owners had declined surgery to treat the ruptured CrCL at the time of diagnosis because of the dog's advanced age. The dog had a 6-month history of weight-bearing lameness of the right pelvic limb lameness caused by complete CrCL rupture, which had been diagnosed elsewhere. At the 2-month recheck examination after implant removal, the dog was walking normally.ĬLINICAL RELEVANCE Simultaneous treatment of tibial fracture and CrCL rupture with unilateral external fixation was successful in this dog and may be helpful in similar cases.Ī 12-year-old obese (37 kg ) spayed female American Staffordshire Terrier was admitted for evaluation of acute non–weight-bearing lameness of the right pelvic limb attributed to motor vehicle–related trauma that occurred 2 hours previously. Both the tibial and fibular fractures healed within 16 weeks after surgery. The 2 main tibial fragments were manipulated via the frame clamps to restore limb length and alignment and tibial plateau slope. TREATMENT AND OUTCOME The tibial fracture and CrCL rupture were treated by closed reduction and simultaneous tibial plateau leveling by indirect fluoroscopic-guided alignment, plus stabilization with a monoplanar external fixator. The fractures were classified as second-degree open, severely comminuted, complex nonreconstructible diaphyseal fractures. Radiography was performed, and tibial and fibular fractures were diagnosed. The dog had non–weight-bearing lameness of the right pelvic limb with associated muscle atrophy and signs of pain on palpation of the right tibia. They had declined surgery for CrCL repair because of the advanced age of the dog.ĬLINICAL FINDINGS Physical examination revealed a 2-cm skin wound on the craniomedial aspect of the midtibial region. The owners reported a chronic, progressive weight-bearing lameness of the right pelvic limb secondary to a complete cranial cruciate ligament (CrCL) rupture that was diagnosed 6 months previously. CASE DESCRIPTION A 12-year-old obese spayed female American Staffordshire Terrier was admitted for evaluation of acute non–weight-bearing lameness of the right pelvic limb attributed to motor vehicle–related trauma that occurred 2 hours previously. ![]()
