Understanding how to classify and quantify three-dimensional (3D) spinal deformities remains an open question in adolescent idiopathic scoliosis. The objective of this study was to perform a 3D manifold characterization of scoliotic spines demonstrating thoracic deformations using a novel geometric and intuitive statistical tool to determine patterns in pathological cases. ⋯ Quantitative evaluation illustrates that the complex space of spine variability can be modeled by a low-dimensional manifold and shows the existence of an additional hyper-kyphotic subgroup from the cohort of 3D spine reconstructions of Lenke Type-1 patients when compared with previous findings on the 3D classification of spinal deformities.

To conduct a cross-cultural adaptation of the Core Outcome Measures Index (COMI) into French according to established guidelines. ⋯ In conclusion, the French version of this short, multidimensional questionnaire showed good psychometric properties, comparable to those reported for German and Spanish versions. The French COMI represents a valuable tool for future multicentre clinical studies and surgical registries (e.g. SSE Spine Tango) in French-speaking countries.

To study the diagnosis and treatment strategy of esophagus perforation complicating anterior cervical spine surgery. ⋯ When a perforation is suspected, imaging techniques should be employed. Surgical treatment facilitates the healing of esophagus perforation. Supportive treatments including prohibition of oral intake, intravenous broad-spectrum antibiotic therapy, feeding with a nasogastric tube were mandatory parts of treatments.

Study aim was to find out if patients with Lenke type 1 curve exhibit smaller pedicles and specific pedicle width pattern compared with individuals with no scoliosis. ⋯ Our study showed that patients with Lenke type 1 curve exhibit smaller pedicles and asymmetric pedicle width compared with control subjects.
