This retrospective study was conducted to evaluate the outcome for cattle with diaphyseal fractures of the femur, but not including capital physeal injuries.
Sources of information were medical records of cattle having a definitive diagnosis of diaphyseal femoral fractures and telephone survey of owners.
Medical records for 26 cattle with femoral fracture were found; of the 20 aged less than 2 months, 15 were treated surgically, 4 conservatively (stall rest) and 1 was euthanased without treatment. The surgical treatment varied according to the configuration of the fracture and the surgeon's experience. Surgery for mid-diaphyseal fractures had a significantly better surgical outcome then distal diaphyseal fractures (P < 0.05), as there were significantly fewer postoperative complications. Of the 15 calves treated surgically, 10 were discharged from hospital and 5 were retained in the herd without noticeable lameness. Of the 4 calves treated conservatively, 3 were alive at follow-up, but 2 were still lame. Of the 6 older cattle, 3 were euthanased without treatment and 3 were treated conservatively, 2 of which were alive at follow-up but 1 was still lame.
Conservative treatment of femur fracture in cattle is possible but associated with complications during the convalescence. Continued research is needed to optimise distal diaphyseal fracture stabilisation in young cattle.
本回顾性研究旨在评估股骨骨干骨折牛的治疗结果，但不包括股骨头骨骺损伤。
信息来源为确诊股骨骨干骨折牛的病历以及对牛主人的电话调查。
共找到26例股骨骨折牛的病历；在20头年龄小于2个月的牛中，15头接受了手术治疗，4头保守治疗（圈舍静养），1头未治疗即实施安乐死。手术治疗根据骨折形态和外科医生的经验而有所不同。骨干中部骨折的手术效果明显优于骨干远端骨折（P < 0.05），因为术后并发症明显更少。在15头接受手术治疗的犊牛中，10头出院，5头留在牛群中，无明显跛行。在4头接受保守治疗的犊牛中，3头在随访时存活，但2头仍跛行。在6头年龄较大的牛中，3头未治疗即实施安乐死，3头接受保守治疗，其中2头在随访时存活，但1头仍跛行。
牛股骨骨折的保守治疗是可行的，但恢复期会出现并发症。需要持续开展研究以优化幼龄牛骨干远端骨折的固定方法。
