PURPOSE The minimally invasive transpsoas approach can be employed to treat various spinal disorders, such as disc degeneration, deformity, and lateral disc herniation. With this technique, visualization is limited in comparison with the open procedure and the proximity of the lumbar plexus to the surgical pathway is one limitation of this technique.(More)
STUDY DESIGN Retrospective review of a series of patients who underwent spinal surgery at a single spine unit during a 1 year period. OBJECTIVES To assess the incidence, treatment, clinical consequence, complications of incidental durotomy during spine surgery and results of 37 months clinical follow-up. SUMMARY OF BACKGROUND DATA Incidental durotomy is(More)
PURPOSE The minimally invasive lateral retroperitoneal transpsoas approach is a recent technique developed for lumbar interbody fusion and discectomy. The proximity of the retroperitoneal vessels and ventral nerve roots to the surgical pathway increases the risk of injury to these anatomical structures. A precise knowledge of the regional anatomy of the(More)
PURPOSE The alignment of the cervical spine is of primary importance to maintain horizontal gaze and contributes to the functional outcome of patients. Cervical spine alignment after correction of major sagittal imbalance has rarely been reported in the literature. METHODS Retrospective review of 31 consecutive patients with sagittal plane deformities(More)
BACKGROUND/PURPOSE Magnetic resonance imaging (MRI) is increasingly used to study skeletal muscles patients with muscular disorders. We report an MRI technique for evaluating the trunk muscles. This technique takes both the component surface area (CSA) and the density of the muscles on MRI axial slices into account . Using a computer-based image analysis(More)
BACKGROUND Lumbar spinal stenosis is degenerative disc disease most common manifestation. If stenosis degree seems poorly related to symptom severity, lumbar muscles role is recognized. Many studies report imaging methods, to analyze muscle volumes and fat infiltration (FI), but remain limited due to the difficulty to represent entire muscle volume(More)
PURPOSE Sagittal malalignment is frequently observed in adult scoliosis. C7 plumb line, lumbar lordosis and pelvic tilt are the main factors to evaluate sagittal balance and the need of a vertebral osteotomy to correct it. We described a ratio: the lumbar lordosis index (ratio lumbar lordosis/pelvic incidence) (LLI) and analyzed its relationships with(More)
The authors report a case of dorsal transscaphoid perilunate dislocation which is noteworthy because there was significant anterior displacement of the lunate together with the proximal part of the scaphoid. The lunate was propelled in front of the radial epiphysis and the proximal part of the scaphoid ended up in front of the metaphyseal part of the(More)
