Percutaneous facet screw fixation of lumbar spine with CT and fluoroscopic guidance: a feasibility study.

Purpose: To assess the feasibility of computed tomography (CT)- and fluoroscopy-guided percutaneous facet screw fixation following anterior lumbar interbody fusion (ALIF) or anterior pseudarthrosis in adults.

Materials And Methods: Institutional review board approval and informed consent were obtained for this study. One hundred seven consecutive adult patients (46 men, 61 women; mean age ± standard deviation: 56.

[Biometric and biomechanic analysis of lumbar posterior facets based on a CT-scan database].

Aim Of The Study: Our knowledge on anatomy of lumbar spine is based on few cadaver's study with old and few subjects. CT-scan is very precise for lumbar facet's morphology. We have analysed 400 subjects.

[Discoscanner: indications, technique, tips and tricks, interpretation].

Discography test associated with the scanner (discoscanner) is an exam that has been a renewed interest in recent few years. Thanks to the emergence of new interventions such as disc prosthesis, the procedures require confirmation of the disc level to deal with and the origin of discogenic symptoms. The aim of this paper is to describe the techniques, challenges and tips as well as the interpretation of functional and morphological examination.

Medicoeconomic evaluation of total disc replacement based on French National Health Care System data.

Introduction: Total disc replacement (TDR) has existed since 1984 but is not covered by the French national healthcare system (Sécurité Sociale). The present study assessed clinical outcomes, and also pre-, peri- and postoperative treatment costs.

Hypothesis: Surgical management of low back pain (LBP) provides medical and economic benefit.

[Posterior percutaneous arthrodesis under CT guidance after surgical anterior arthrodesis: a new technique].

Transfacet screws may be useful for stabilizing segments reconstructed with bone graft or cages, the role of supplementary posterior fixation, particularly minimally invasive techniques such as transfacetar percutaneous screws is relevant. To benefit from a mechanical fixation after anterior arthrodesis without the inconveniences of the open classical posterior surgical intervention, we have developed a new procedure performed under local anesthesia and CT guidance and based on the intra-articular application of screws. This study was designed to demonstrate the feasibility of using a CT-scan to perform posterior arthrodesis of the spine under local anesthesia.
