Abstract 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.
