Brief Summary

Neurogenic paraosteoarthropathies are peri-articular bone formations that may occur as a result of central neurological injury. Their occurrence limits reeducation and recovery capacities. Neurogenic paraosteoarthropathies sometimes cause complications (pain, joint stiffness, vascular and nerve compression, pressure sores) in patients already suffering from severe neurological sequelae affecting functional prognosis. A lot of clinical research work has been carried out within Dr Salga team. Subsequently, a collaboration was born with fundamental research teams (Pr Levesque, Pr Le Bousse Kerdilès, Pr Banzet, Pr Genêt) allowing translational work between humans and animals. The clinical application of recent research findings now makes it possible to launch the very first prospective study on neurogenic paraosteoarthropathies.

Detailed Description

Based on the results of collaborative and translational (human-animal) work, investigators wish to conduct the first prospective study that would allow:

(i) To assess the incidence of Neurogenic paraosteoarthropathies (clinical suspicion and radiological confirmation). The prospective nature of this clinical data collection will make it possible to avoid the biases attributed to the retrospective studies conducted to date.

ii) Early detection of patients at risk of developing Neurogenic paraosteoarthropathies, using specific biomarkers and clinical parameters. Early diagnosis could prevent complications and functional impact of Neurogenic paraosteoarthropathies.

Investigators have chosen to restrict population to patients most at risk of developing Neurogenic paraosteoarthropathies as a result of the central neurological event in order to have 2 populations appear at the end of the study: a population with Neurogenic paraosteoarthropathies and a population without Neurogenic paraosteoarthropathies that can be compared.
