ority of subaxial cervical spine traumatic injuries.Level of Evidence 4.

The AO Spine Subaxial Cervical Spine Injury Classification System has shown to be reliable and suitable for proper patient management. The study shows this classification is substantially generalizable by geographic region and surgeon experience, and provides a consistent method of communication among physicians while covering the majority of subaxial cervical spine traumatic injuries.Level of Evidence 4.

Biomechanical cadaveric study.

The aim of this study is to evaluate the effect of degeneration on biomechanical properties of the passive structures of the lumbar spine.

While the load apportionment among the passive structures in healthy spines follows well-defined contribution patterns, it remains unknown how this load distribution and sagittal preload changes by degenerative processes of the intervertebral disc (IVD).

50 lumbar spinal segments were tested in a displacement-controlled stepwise reduction study in flexion, extension, axial rotation, lateral bending, anterior, posterior and lateral shear. The intertransverse ligaments (ITL), supraspinous and interspinous ligaments (ISL&SSL), facet joint capsules (FJC), facet joints (FJ), ligamentum flavum (LF), posterior longitudinal ligament (PLL), anterior longitudinal ligament (ALL) and spondylophytes (SP) were subsequently reduced. The results were set in relation to IVD-degeneration, quantified with Pfirrmann classification.

In flexion, a loo notable load-redistributions between the passive spinal structures. With further degeneration, reduced contribution of the LF and PLL and higher loads on the IVD are observed in flexion. VEGFR inhibitor In the other tested loading directions, the relative load on the IVD is reduced, while higher FJ-exposure in axial rotation, anterior and lateral shear is observed. Furthermore, the preload of the spinal structures is reduced. These observations can further the understanding of the degenerative cascade in the spine.Level of Evidence N/A.

Retrospective review of prospective multicenter database.

The aim of this study was to investigate how preoperative mental status affects preoperative and postoperative disability and health scores in adult spinal deformity (ASD) patients.

The relationship between health-related quality of life (HRQOL) and depression has previously been documented. However, the influence of depression on clinical outcomes among ASD patients is not well understood.

ASD patients with minimum 2-year follow-up were stratified based on preoperative mental health measured by Short Form 36 (SF-36) mental component score (MCS). Patients with MCS in the 25th and 75th percentile of the cohort were designated as having low and high MCS, respectively. After matching by preoperative demographics and deformity, pre- and post-HRQOL were compared between the two groups. Further analysis was performed to identify individualized questions on the SF-36 that could potentially screen for patients with low MCS.

Five hundred thirteen patiless likely to be satisfied postoperatively, even when similar clinical goals are achieved. Incorporating psychological factors may assist in decision making.Level of Evidence 3.

ASD patients with low MCS are more likely to experience functional limitations before and after surgery and are less likely to be satisfied postoperatively, even when similar clinical goals are achieved. Incorporating psychological factors may assist in decision making.Level of Evidence 3.

Prospective cross-sectional study.

We designed this study to investigate whether adolescent girls with idiopathic scoliosis show a predisposition for eating disorders (EDs) and alterations of the quality of life and body image self-perception, compared to same-age healthy females.

Idiopathic scoliosis is the most common spinal deformity of adolescence. Recent findings about the impairment of the self-body image in adolescents with idiopathic scoliosis provide a common trait of scoliosis and EDs and could lead to the suspicion of an association between these two pathological conditions. Despite this, current literature shows the lack of evident results about the impact of adolescent idiopathic scoliosis (AIS) on the possibility to develop of EDs.

One hundred forty-four females with diagnosis of AIS (aged 10-18 years) formed the scoliosis group. One hundred forty-six same-age healthy girls were enrolled in the control group. For all subjects, we considered sport practice. Only for Scoliosis Group, we al not seem to be affected by orthotic management. However, quality of life and self-body image could be impaired in scoliotic girls, especially when they practice physiotherapy exercises, whereas those who practice sport seem to be preserved in this regard.Level of Evidence 4.

The AIS cohort in our study demonstrated lower levels of eating psychopathology than healthy controls. Surprisingly, eating behavior does not seem to be affected by orthotic management. However, quality of life and self-body image could be impaired in scoliotic girls, especially when they practice physiotherapy exercises, whereas those who practice sport seem to be preserved in this regard.Level of Evidence 4.

A retrospective cross-sectional study.

This study aims to determine whether the sacroiliac (SI) joint motion correlated to pelvic incidence (PI) change from standing to supine position in patients with degenerative spinal diseases.

PI was found an unstable parameter after adolescence as the fixed nature of PI was challenged by several studies. The SI joint has been shown to have some motion, age-related degenerative changes of cartilage and SI ligaments contribute to SI joint instability.

The study contains both specimen study and radiographic study. One human specimen was acquired, on which PI was measured with different sacrum-ilium positions. In radiographic study, patients with old thoracolumbar fracture, lumbar disc herniation, stenosis, and spondylolisthesis were included. Ankylosing spondylitis (AS) patients were also included as control group. PI was measured on standing x-rays and scanogram of computed tomography images in supine position.

Specimen study result revealed that SI motion would lead to the change of PI with fixed pelvic thickness.
