Topic: Mandible Fractures
Presenter: Dr. Jose Luis Cebrian
Time: 47 minutes
In the field of mandibular fracture treatment, osteosynthesis failures are not very frequently found. Nevertheless, when they happen, it is not difficult to find a biomechanical explanation to these events.
The purpose of this lecture is to analyze the biomechanical principles related to the masticatory muscle-skeletal system that must be taken in consideration to avoid ostheosynthesis failure. A secondary objective is to establish the basis of treatment in case of non-union related to this failures.
To cover the first objective, we develop a thorough review of the four principles for predictable fracture treatment:
1. Anatomic reduction of the fractures
2. Stable ostheosynthesis taking in consideration biomechanical aspects
3. Non-traumatic surgical technique
4. Active mobilization, of muscles and joints nearby the fracture.
During this review we analyze concepts related to:
1. Type of fracture. Displacement, location, number of them
2. Type of ostheosynthesis: rigid, mecanically stable, load-sharing, load-bearing, locking vs. non-locking plates...
3. Type of patient: age, co-morbidities
We also outline the principles of treatment for ostheosynthesis failure focusing on the biomechanics of the masticatory system and the rational use of grafts.
Finally we propose clinical cases to illustrate the conclusions of the lecture, that in our opinion are the following:
1. System Biomechanic preservation is the base to prevent failures.
2.- In the case of a mandibular fracture we should follow the four principles for predictable treatment..
3.-This four principles should be observed during ostheosynthesis failure treatment.
