【摘要】 1只6月龄雄性博美犬，2个月前从沙发上摔下后左前肢持续不负重，服用止疼药后未见明显好转。骨科检查发现患犬左前肢肘关节屈曲内旋、伸展受限，鹰嘴外旋，肌肉量较右前肢少，肘关节伸展受限。CT扫查可见左侧肱尺关节脱位，尺骨近端相对于肱骨远端向外旋转约90度。综合病史、骨科检查及CT扫查结果诊断为左侧先天性肘关节Ⅱ型(肱尺关节)脱位。通过尺骨近端截骨术复位肱尺关节，并固定近端尺骨和桡骨进行治疗。术后10个月电话回访，该犬左前肢功能恢复良好。说明对于先天性肘关节Ⅱ型脱位的病例，可采用尺骨近端截骨术进行肱尺关节复位及尺骨与桡骨固定来治疗。更多还原

【Abstract】 A 6-month-old male Pomeranian, falling from the sofa 2 months ago, continued to be not weight-bearing on his left forelimb, and did not see significant improvement after taking painkillers. Orthopedic examination showed that the affected dog has limited flexion and extension of the elbow joint of the left forelimb and external rotation of the olecranon, with less muscle mass than the right forelimb and limited extension of the elbow joint. CT scanning revealed left humerulnar joint dislocation, with the proximal ulna rotating outward approximately 90 degrees relative to the distal humerus. Based on the medical history, orthopedic examination and CT scanning, it was confirmed that the congenital left elbow joint(humerulnar joint) dislocation type Ⅱ was confirmed. The humerulnar joint was reduced by proximal ulna osteotomy and treatment was performed by fixation of the proximal ulna and radius. The telephone return visit 10 months after surgery showed that the dog’s left forelimb function recovered well. The results suggested that for cases of congenital elbow joint dislocation type Ⅱ, proximal ulnar osteotomy could be used for the treatment of humerulnar joint reduction and ulna and radius fixation.更多还原
