OBJECTIVE
To find out how the site and type of condylar fracture are affected by its aetiology and the age and sex of the patient.
DESIGN
Retrospective study.
SETTING
Tertiary referral centre, Finland.
MATERIAL
Radiographs of 101 children (aged 15 years or less) with 119 condylar fractures.
MAIN OUTCOME MEASURES
Site of fracture and degree of displacement.
RESULTS
A total of 26 of the 119 fractures were intracapsular (22%) and 93 (78%) extracapsular. Only among patients less than 6 years of age was there a preponderance of intracapsular fractures (7/12 fractures in 10 patients, 58%). In the older children 78% (83/107) were in the condylar neck. There were few subcondylar fractures (5/119, 4%). Only 6 fractures were displaced (5%). Dislocation of the condyle from the glenoid fossa was common in all age groups.
CONCLUSION
The site of condylar fracture is age related, but not associated with sex or aetiology.
目的
探究髁突骨折的部位和类型如何受其病因以及患者年龄和性别的影响。
设计
回顾性研究。
地点
芬兰的三级转诊中心。
材料
101名15岁及以下儿童的119例髁突骨折的X线片。
主要观察指标
骨折部位和移位程度。
结果
119例骨折中共有26例为囊内骨折（22%），93例为囊外骨折（78%）。仅在6岁以下患者中囊内骨折占优势（10例患者中的12例骨折中有7例，58%）。在年龄较大的儿童中，78%（83/107）的骨折位于髁突颈部。髁突下骨折很少（5/119，4%）。仅6例骨折有移位（5%）。髁突从关节窝脱位在所有年龄组中都很常见。
结论
髁突骨折的部位与年龄有关，但与性别或病因无关。
