简要总结
This pilot study is part of a global project that aims to better define and understand features of FBSS/POPS "post-operative persistent syndrome patients (shortened as "FBSS" in the following project). FBSS is the acronym for Failed Back Surgery Syndrome, which has been defined as a chronic condition resulting from spinal interventions. Despite anatomically successful spine surgery, a significant proportion of patients is experiencing chronic refractory back and leg pain. In a recent multicentre study conducted on more than 100 refractory FBSS patients, (ESTIMET Study), the mean delay between pain occurrence and FBSS diagnosis was 5 years. Therefore, FBSS pattern and potential responder stratification might guide us to eventually develop a decision tool for identifying FBSS patients. Easing and helping diagnosis of FBSS should improve referral yield to specialists and accelerate patient flow through the care pathway. Hence, FBSS patients, who usually present a long standing history of pain, would have access to "appropriate" therapies earlier. This could lead to better outcomes. The aim of this multicentre, prospective study is to collect specific data that are not collected in routine in order to better define and understand the potential FBSS population and to accelerate the diagnostic and optimize the choice of appropriate treatment.
A multidisciplinary approach through a pain management clinical network, as it has been structured in Poitiers, will ensure that an exhaustive characterization of FBSS patients and their care pathway will be collected. In addition, since the cooperation between orthopaedic and neuro spine surgeons is not a common relationship found all over Europe (as it is observed in Poitiers), this study also aims to better understand the development of interactions between physicians/professionals and the substantial advantage which would result from bridging this gap. The N3MT (NeuroMapping Tools) software developed in Poitiers to collect data and assess objectively pain surface and intensity changes, before/after any treatment, with quantitative measurements, will be used as the central key of this project.
