Five New World camelids were admitted to the Western College of Veterinary Medicine between 1996 and 2003 for evaluation of femoral fractures. There were three alpacas and two llamas. Four of the animals were female and three were less than 3 months of age. Fracture configurations consisted of distal physeal fractures (three), a comminuted diaphyseal/metaphyseal fracture, and a transverse diaphyseal fracture. Fractures were diagnosed with a combination of physical examination and radiographs in all cases. All five fractures were repaired with internal fixation and three animals were discharged from the hospital with fractures that healed. One cria underwent successful internal fixation but died from pulmonary oedema during recovery from anaesthesia. Postoperative complications were rare and limited to inadequate fracture stability in one alpaca and prolonged recovery to weight bearing in another. One llama with a comminuted metaphyseal fracture, repaired with a 4.5 mm dynamic compression plate, subsequently had catastrophic failure of the bone 17 days after surgery. Overall the clients were pleased with the outcome of discharged animals. Although femoral fractures are considered rare, they pose a unique opportunity for the large animal veterinarian to successfully achieve fracture union with the aid of internal fixation.
1996年至2003年间，有5只新大陆骆驼科动物被送往西部兽医学院评估股骨骨折情况。其中有3只羊驼和2只美洲驼。这些动物中有4只为雌性，3只年龄小于3个月。骨折类型包括远端骨骺骨折（3例）、粉碎性骨干/干骺端骨折和横行骨干骨折。所有病例均通过体格检查和X光片相结合的方式诊断出骨折。所有5处骨折均采用内固定修复，3只动物出院时骨折已愈合。1只幼畜内固定手术成功，但在麻醉恢复过程中死于肺水肿。术后并发症很少见，仅1只羊驼出现骨折固定不充分，另1只恢复负重时间延长。1只患有粉碎性干骺端骨折的美洲驼，用4.5毫米动力加压钢板修复，术后17天出现灾难性的骨衰竭。总体而言，客户对出院动物的治疗结果感到满意。尽管股骨骨折被认为较为罕见，但对于大型动物兽医来说，借助内固定成功实现骨折愈合是一个独特的机会。
