Lack of performance

For les intra-articular fractures, plate osteosynthesis is the indicated technique. Despite the absence of consensus, in recent years, the use of open reduction associated with internal plate fixation has considerably developed. Indeed, this therapeutic option allows a more anatomical reduction and stable fixation.

First-generation posterior plates presented complications related to the size of the plate, notably tendon lesions. Over the last ten years, a new generation of thinner anterior plates has reduced these complications.

In the literature, few studies have compared these two techniques in terms of functional and radiological outcomes. The hypothesis of this research is that osteosynthesis using a posterior plate is more effective than that with an anterior plate in terms of functional recovery in patients older than 45 years.
