To determine the risk of condylar fracture, or of needing to have a transcondylar screw placed, and to identify risk factors in a cohort of dogs with humeral intracondylar fissure (also known as incomplete ossification of the humeral condyle) that was initially managed non-surgically.
A retrospective owner survey of dogs diagnosed with humeral intracondylar fissure as an incidental finding and managed non-surgically with a minimum of two years follow-up. Body weight, age, estimated fissure size, gender and contralateral fracture at the time of diagnosis were evaluated as potential risk factors for the development of a humeral condylar fracture or for having a transcondylar screw placed.
Data were available for 30 dogs (34 elbows). Six humeral condyles with a mean fissure size of 50% fractured at a mean of 14 months after diagnosis. A transcondylar screw was placed across two humeral condyles with fissure sizes of 60 and 100% at 11 and 17 months. No risk factors were identified for fracture/screw placement. For those cases that did not fracture or have a screw placed mean fissure size was 52% and mean follow-up time was 56 months (range 29 to 79 months).
Eighteen percent of cases progressed to fracture and 24% in total required surgery. This information allows clinicians and owners to make an informed decision regarding surgery when faced with a dog with humeral intracondylar fissure identified as an incidental finding.
确定患有肱骨髁间裂（也称为肱骨髁不完全骨化）且最初采用非手术治疗的犬只队列中髁突骨折或需要置入髁间螺钉的风险，并识别相关风险因素。
对诊断为肱骨髁间裂且为偶然发现并接受非手术治疗且至少随访两年的犬只进行回顾性主人调查。评估体重、年龄、估计的裂缝大小、性别和诊断时的对侧骨折情况，作为肱骨髁骨折发生或置入髁间螺钉的潜在风险因素。
有30只犬（34个肘部）的数据可用。6个平均裂缝大小为50%的肱骨髁在诊断后平均14个月发生骨折。在11个月和17个月时，分别对裂缝大小为60%和100%的2个肱骨髁置入了髁间螺钉。未识别出骨折/螺钉置入的风险因素。对于未发生骨折或未置入螺钉的病例，平均裂缝大小为52%，平均随访时间为56个月（范围29至79个月）。
18%的病例进展为骨折，总计24%的病例需要手术。这些信息使临床医生和主人在面对偶然发现肱骨髁间裂的犬只时，能够就是否进行手术做出明智的决定。
