[Percutaneous neuromodulation with pulsating radiofrequency vs cryoablation for the treatment of patients with lumbar facet syndrome].

Introduction: lumbar spine pain affects a high percentage of the population and has a significant socioeconomic impact. Lumbar facet syndrome has a prevalence between 15-31% with lifetime incidence of up to 52% in some series. Due to the use of different types of treatment and different patient selection criteria, the success rate varies in the literature.

[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.

[Application of the Graf method for diagnosis and early detection of hip dysplasia].

Introduction: Developmental hip dysplasia (DHD) is the most common disorder affecting pediatric hip; screening all neonates clinically, and using ultrasonography selectively for those babies who are at high risk is a widespread recommendation. our goal is to evaluate the impact that USG diagnosis and early treatment of DHD has had on the child population of our unit.

Material And Methods: Retrospective, descriptive and cross-sectional study.

[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.
