Prospective data will be collected in approximately 250 patients sustaining BCFx with or without any additional fracture(s) of the symphysis. Patients will be followed according to the standard (routine) at approximately 6 weeks and 3 months after the treatment. Data collection will include fracture details (i.e. classification, mechanism of injury), treatment details, functional and patient-reported outcomes, and anticipated or procedure-related adverse events (i.e. complications).

Detailed Description

Fractures of the condyles occur in around one third of patients sustaining a mandibular fracture. Bilateral fractures are reported in around one fifth to one third of all fractures of the mandibular condyles and are often combined with other fractures of the mandible or facial skeleton.

The treatment of condylar fractures, and in particular of bilateral condylar fractures (BCFx), is complex due to many different fracture patterns, surgeon's preferences, local constraints of the health care system and patient characteristics. Briefly, BCFx can be treated using either closed treatment (CTx) (e.g. intermaxillary fixation [IMF] and/or functional therapy) or surgical treatment (i.e. open reduction and internal fixation [ORIF]) in both fractures, or a combination of closed treatment and ORIF. The relationship of these treatments with the final outcome remains elusive, since the available literature does not report specific data for patients sustaining BCFx and has ignored or inadequately reported patient-reported outcomes. Consequently there is a lack of clinical evidence to assist the decision-making process.

Therefore, the purpose of this registry is to collect data in a standardized manner regarding the treatment, the clinical and the patient-oriented outcomes, and the complications of BCFx.


Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
