To determine the outcome of femoral fractures repaired with 4.0- and 4.7-mm interlocking intramedullary nails in cats.
Retrospective study.
12 cats with diaphyseal femoral fractures.
Records of all cats in which the 4.0- and 4.7-mm interlocking nail system was used for repair of diaphyseal femoral fractures at the Animal Medical Center and Florida Veterinary Specialists between 1996 and 2000 were reviewed. Information included signalment, type of fracture, size of the implant, details of the surgery, intra- and postoperative complications, fracture healing, and clinical outcome.
Femoral fractures in 12 cats were repaired. Eleven of the fractures were comminuted, with 2 of these being open. Clinical outcome was excellent in 7 cats, good in 3, and fair in 1. One resulted in a nonunion. Complications included screw breakage (1 cat) and fracture distal to the nail (1). Fracture distal to the nail occurred from a second trauma.
Use of the interlocking nail has been limited in cats because of the small diameter of the medullary canal. Use of the 4.0-mm nail will allow for greater application of this implant in small patients. Results of this study indicate that the 4.0- and 4.7-mm interlocking nails can be used to repair simple or comminuted diaphyseal femoral fractures in cats.
确定使用4.0毫米和4.7毫米带锁髓内钉修复猫股骨干骨折的效果。
回顾性研究。
12只股骨干骨折的猫。
回顾了1996年至2000年间在动物医疗中心和佛罗里达兽医专科医院使用4.0毫米和4.7毫米带锁髓内钉系统修复股骨干骨折的所有猫的记录。信息包括特征、骨折类型、植入物尺寸、手术细节、术中和术后并发症、骨折愈合情况及临床结果。
12只猫的股骨干骨折得到修复。其中11处骨折为粉碎性骨折，2处为开放性骨折。7只猫临床结果优秀，3只良好，1只尚可。1例出现骨不连。并发症包括螺钉断裂（1只猫）和钉远端骨折（1例）。钉远端骨折由二次创伤引起。
由于猫的髓腔直径较小，带锁髓内钉在猫中的应用受到限制。4.0毫米髓内钉将使该植入物在小型动物中得到更广泛应用。本研究结果表明，4.0毫米和4.7毫米带锁髓内钉可用于修复猫的简单或粉碎性股骨干骨折。
