Fifteen cases of radial fractures in adult horses weighing more than 300 kg are discussed. Four of the horses were destroyed on humane grounds immediately because of a poor prognosis and expense of internal fixation; and two horses at five days and five weeks, respectively after treatment by cast application was initiated. Internal fixation was used in nine horses but of these only two horses recovered completely and resumed their former activities. In eight cases, two plates were applied, one lateral or medial and the other cranial. The internal fixation techniques of all nine horses were scrutinised and suggestions made for the future treatment of radial fractures. These suggestions are (1) the use of ASIF 5.5 mm cortical bone screws using the total width or thickness of the bone in each case. (2) Application of the dynamic condylar screw with its plate in distal or proximal fractures to allow more support. (3) Incorporation of a cancellous bone graft to the fracture. (4) Possible table recovery to prevent breakdown of the fixation during recovery. It is important that bone plates are applied over the total length of the bone. The fact that only two out of 15 horses survived and recovered completely underlines the problems associated with treatment of radial fractures in the adult horse.
讨论了15例体重超过300公斤成年马的桡骨骨折病例。其中4匹马因预后不良和内固定费用高昂，立即被人道毁灭；另外两匹马分别在开始石膏固定治疗后的第5天和第5周死亡。9匹马采用了内固定，但其中只有两匹马完全康复并恢复了以前的活动。8例中，应用了两块钢板，一块置于外侧或内侧，另一块置于颅骨侧。对所有9匹马的内固定技术进行了审查，并对桡骨骨折的未来治疗提出了建议。这些建议是：（1）根据每种情况使用ASIF 5.5毫米皮质骨螺钉，螺钉应贯穿骨的总宽度或厚度。（2）在远端或近端骨折中应用动力髁螺钉及其钢板，以提供更多支撑。（3）在骨折处植入松质骨移植。（4）可能的术后康复措施，以防止康复过程中固定失败。将骨板覆盖在骨的全长上很重要。15匹马中只有两匹完全存活并康复，这一事实凸显了成年马桡骨骨折治疗中存在的问题。
