The objective of this study was to evaluate an X-ray films analysis software, i.e. to estimate the reliability and validity of clinical measurements by means of this software. The authors first performed tests of precision and reproducibility of measures. The precision for dynamic modules was estimated at ±2° for the lumbar analysis and ±3° for the cervical(More)
The purpose of the study was to report radiological outcomes after total disc replacement (TDR) in the cervical spine through a 24 months follow-up (FU) prospective study with a special focus on sagittal alignment and kinematics at instrumented and adjacent levels. Thirty-two patients, who sustained one-level TDR with a ball-and-socket arthroplasty(More)
Though the anterior lumbar interbody fusion with cages is an interesting option in the treatment of discogenic low back pain, cage-related complications opened the way to alternative options like circumferential fusion or recent ALIF techniques using cages and anterior instrumentation. As the latter are rather recent, the aim of this prospective study was(More)
The outcome assessment in instrumented lumbosacral fusion mostly focuses on clinical criteria, complications and scores, with a high variability of imaging means, methods of fusion grading and parameters describing degenerative changes, making comparisons between studies difficult. The aim of this retrospective evaluation was to evaluate the interest of(More)
Adult low-grade isthmic spondylolisthesis is often treated by posterolateral lumbar fusion (PLF), with a certain rate of complications and non-return to work. Alternatives to fusion, like pars defect repair (PDR), were used with encouraging results in young populations and athletes but their outcomes were rarely evaluated for adult patients. This(More)
Dynamic systems in the lumbar spine are believed to reduce main fusion drawbacks such as pseudarthrosis, bone rarefaction, and mechanical failure. Compared to fusion achieved with rigid constructs, biomechanical studies underlined some advantages of dynamic instrumentation including increased load sharing between the instrumentation and interbody bone graft(More)
Though well described in the literature, technical and clinical results of posterolateral fusion (PLF) in degenerative lumbar spine do not always reflect patient’s perception of outcome or satisfaction. Several tools were proposed for an objective outcome assessment: clinical scores, questionnaires investigating psychosocial factors and biomechanical X-ray(More)
