To report metacarpal fracture repair in a bull.
Clinical report.
Simmental bull (n = 1; 870 kg).
A comminuted right metacarpal fracture was repaired using 2 transfixation pins (6 mm diameter) through the distal metaphysis and diaphysis of the radius and a full limb synthetic resin cast.
Slight bending of both pins occurred 1 day after surgery. Both pins were loose and removed at 31 days and a full-limb cast reapplied. The cast was changed at approximately -4 week intervals. On day 50, the right carpus had moderate overextension and a valgus deformity. An exercise program was started on day 62, and on day 110, the cast was replaced with a Robert-Jones-bandage. At 130 days there was circumferential callus formation and the bull was discharged. At 6.5 months, overextension of the right carpus had resolved and carpal valgus had improved. The bull returned to at 7.5 months after surgery, and was successfully used for 4 years.
For highly valuable cattle like this breeding bull, a surgical treatment of such a fracture should be attempted despite a primarily poor prognosis.
报告一头公牛掌骨骨折的修复情况。
临床报告。
西门塔尔公牛（n = 1；870千克）。
通过2根直径6毫米的贯穿针经桡骨远端干骺端和骨干修复右侧粉碎性掌骨骨折，并应用全肢合成树脂石膏。
术后1天两根针均出现轻微弯曲。两根针均松动，于31天时取出并重新应用全肢石膏。大约每隔4周更换一次石膏。在第50天时，右腕关节出现中度过度伸展和外翻畸形。在第62天开始实施运动计划，在第110天时，石膏被换成罗伯特-琼斯绷带。在130天时出现环形骨痂形成，公牛出院。在6.5个月时，右腕关节的过度伸展已消失，腕关节外翻有所改善。该公牛在术后7.5个月时恢复，成功使用了4年。
对于像这头种公牛这样的高价值牛，尽管最初预后不佳，仍应尝试对这种骨折进行手术治疗。
