Introduction and Objective. The treatment of severe deformities often requiring aggressive techniques such as vertebral resection and osteotomies with high comorbidity. To mitigate this risk, several methods have been used to achieve a partial reduction of stiff curves. The objective of this study was to evaluate and quantify the effectiveness of the Perioperative Halo-Gravity Traction (HGT) in the Treatment of Severe
Introduction and Objective. Pectus carinatum is a common congenital anterior chest wall deformity, characterized by outward protrusion of sternum and ribcage resulted from rib cartilage overgrowth. The protrusion may be symmetrical or asymmetrical. Pectus carinatum association with mitral valve diseases, Marfan's syndrome, and scoliosis enforces that poor connective tissue development as possible etiological factor. Despite the coexistence of pectus carinatum and scoliosis has attracted the attention of some researchers, the association between pectus carinatum and the other
Intervertebral disc (IVD) degeneration is responsible for severe clinical symptoms including chronic back pain. Galectins are a family of carbohydrate-binding proteins, some of which can induce functional disease markers in IVD cells and other musculoskeletal diseases. Galectins −4 and −8 were shown to trigger disease-promoting activity in chondrocytes but their effects on IVD cells have not been investigated yet. This study elucidates the role of galectin-4 and −8 in IVD degeneration. Immunohistochemical evidence for the presence of galectin-4 and −8 in the IVD was comparatively provided in specimens of 36 patients with spondylochondrosis, spondylolisthesis, or
The pelvic girdle and spine vertebral column work as a long chain influenced by pelvic tilt.
Spinal surgery deals with the treatment of different pathological conditions of the spine such as tumors, deformities, degenerative disease, infections and traumas. Research in the field of vertebral surgery can be divided into two main areas: 1) research lines transversal to the different branches; 2) specific research lines for the different branches. The transversal lines of research are represented by strategies for the reduction of complications, by the development of minimally invasive surgical techniques, by the development of surgical navigation systems and by the development of increasingly reliable systems for the control of intra-operative monitoring. Instead, specific lines of research are developed within the different branches. In the field of oncological pathology, the current research concerns the development of in vitro models for the study of metastases and research for the study of targeted treatment methods such as electrochemotherapy and mesenchymal stem cells for the treatment of aneurysmal bone cysts. Research in the field of

Summary Statement. Patients with adolescent idiopathic scoliosis show clear signs of abnormal motor coordination between the long superficial paraspinal muscles and the deep rotators. These findings suggest an abnormal behavior of the deep rotator muscles at the concave side. Introduction. An imbalance between the myoelectric activity of the muscles of the convexity and the concavity has been described in patients with adolescent idiopathic scoliosis (AIS). These findings are based on EMG patterns recorded with surface electrodes that do not distinguish between deep and superficial muscles. This work was aimed at analyzing the coupled behavior of the superficial and deep paraspinal muscles in subjects with AIS at both sides of the curve. Material. A total of 16 females (mean age, 16.2±4.3 years) with AIS between 20 and 35° Cobb (mean, 32.8±11.9°) underwent electromyography of the paraspinal muscles by direct intramuscular disposable concentric electrodes (Dantec DCN. TM. ) of 25mm and 37mm in length, and 0.46 mm. in diameter. A total of 4 electrodes were inserted at the apex on both sides of the curve (2 in deep rotator muscle and 2 in the long paraspinal superficial muscles). Myoelectrical activity was recorded simultaneously in the four muscle groups in different positions: standing, flexion, extension, right and left lateralizations, and rotations toward the side of the concavity and convexity. A 4-channel Keypoint® electromyography device (Medtronic, Denmark) was used. The recorded signals were analyzed in a laptop with Windows. ®. 7 Intel Core i3 64bit with Matlab. ®. R2012a. The following parameters were analyzed: Signal power, Mean and Median frecuency, and the Dimitrov spectral index, a marker of muscle fatigue. In addition, the signal power in each task was normalised by the signal power in standing position. The records were compared with those obtained in 4 healthy subjects, matched in age, without
