To investigate the incidence of implant-related complications when humeral unicondylar fractures in immature dogs are stabilised with a transcondylar bone screw and epicondylar Kirschner wire (K-wire)/pin.
Records of cases treated by the author in this clinic over a 10-year period were screened for those involving humeral condylar fractures. These were then reduced to include those patients who were less than 7 months of age with unicondylar fractures and follow-up radiographs.
Thirty fractures in 29 dogs met the inclusion criteria. All of these had been stabilised with a transcondylar bone screw and epicondylar K-wire. Fracture healing was documented in all dogs. Surgical site infection was not recorded. Implant-related major complications were reported in four (13%) dogs and successfully treated by either implant removal or replacement. Short-term outcome was judged as excellent in 23 out of 30 and good in seven out of 30 of these fractures.
The use of a transcondylar bone screw in combination with an epicondylar K-wire is an appropriate fixation method for humeral unicondylar fractures seen in puppies less than 7 months of age.
研究在月龄小于 7 个月的犬只的肱骨髁骨单髁骨折中，使用经髁骨螺钉和髁外克氏针/销固定时，与植入物相关的并发症的发生率。
对作者所在诊所 10 年来的病例记录进行筛选，找出涉及肱骨髁骨折的病例。然后将这些病例进行简化，纳入年龄小于 7 个月的犬只的单髁骨折和随访的 X 光片。
30 例 29 只犬的骨折符合纳入标准。所有病例均采用经髁骨螺钉和髁外克氏针固定。所有犬只均有骨折愈合的记录。未记录到手术部位感染。4 只（13%）犬报告了与植入物相关的主要并发症，并通过植入物取出或更换成功治疗。30 例中，23 例短期结果为优，7 例为良。
对于月龄小于 7 个月的犬只的肱骨髁骨单髁骨折，使用经髁骨螺钉联合髁外克氏针是一种合适的固定方法。
