[Treatment of severe spinal deformity with 3D printing models].

Scoliosis is a complex deformity that affects all three planes of the axis of the spine. The association between neuromuscular pathology and vertebral alignment was initially described in 1960. Neuromuscular pathology is progressive and results in postural abnormalities.

[Biomechanical analysis of interespinous ligamentoplasty with polyester fiber after discectomy].

Introduction: There are different pathologies of the lumbar spine that condition a biomechanical and clinical instability for its treatment, various stabilization techniques have been carried out that try to preserve the movement and the transmission of load of the affected segment such as the interspinatus ligamentplasty with Dallos® fiber.

Objective: To show the biomechanical variations of functional segment of lumbar spine of pigs, before and after performing the discectomy and ligamentoplasty with Dallos® fiber.

Material And Methods: The lumbar segment was mounted in a servo-hydraulic multiaxial simulator.
