Bilateral Condylar Fractures Registry

Study Overview
=================
Brief Summary
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mandibular movements (mobility index) | Interincisal opening/maximal opening is defined as distance in millimeters between the edges of the incisors of the mandibular and the maxillary bone. Lateral movements: With the mandible slightly open, it is defined as the distance in millimeters from the labioincisal embrasure between the central incisors to the labioincisal embrasure of the mandibular incisors Protrusive movement: With the mandible slightly open, it is defined as the distance in millimeters between the incisal edges of the maxillary central incisor to the mandibular central incisor. Depending on the score, the mobility index will be calculated as follow: 0 points: normal mandibular mobility 1 - 4 points: slightly impaired mobility 5 - 20 points: severely impaired mobility | 3 months |
