Traumatic spinal injuries often require surgical fixation. Specific three-dimensional degrees of instability after spinal injury, which represent criteria for optimum treatment concepts, however, are still not well investigated.

The aim of this review therefore was to summarize and quantify multiplanar instability increases due to spinal injury from experimental studies.

Systematic review.

A systematic review of the literature was performed using keyword-based search on PubMed and Web of Science databases in order to detect all in vitro studies investigating the destabilizing effect of simulated and provoked traumatic injury in human spine specimens. selleck kinase inhibitor Together with the experimental designs, the instability parameters range of motion, neutral zone and translation were extracted from the studies and evaluated regarding type and level of injury.

A total of 59 studies was included in this review, of which 43 studies investigated the effect of cervical spine injury. Range of motion increase, which was repon should be preferred to resection or transection of structures to ensure high comparability with the clinical situation.

Specific traumatic spinal injuries produce characteristic but complex three-dimensional degrees of instability, which depend on the type, level, and morphology of the injury. Future studies should expand research on the cervicothoracic, thoracic, and lumbosacral spine and should additionally investigate the destabilizing effects of the injury morphology as well as concomitant rib cage injuries in case of thoracic spinal injuries. Moreover, neutral zone and translation should be measured in addition to the range of motion, while mechanical injury simulation should be preferred to resection or transection of structures to ensure high comparability with the clinical situation.

The emergence of drug resistance has complicated the management of spinal tuberculosis (TB). While it is well known that the medical management of drug-resistant spinal TB is more difficult, the surgical outcomes of the same have not been studied sufficiently, particularly in children.

To analyze the surgical outcomes in a cohort of children treated for spinal TB, and to thus assess whether drug resistant (DR) disease is associated with poorer surgical outcomes.

Retrospective observational study.

All children diagnosed and treated for tuberculous spondylodiscitis at a single center between January 2014 and June 2017.

Surgical outcomes in terms of neurological status and kyphosis angle at final follow-up, and complication rates.

Radiographic and clinical data of children treated for spinal TB with minimum two-year follow-up were retrospectively analyzed. Data gathered included age, gender, level of spine affected, number of vertebrae involved, neurology (Frankel grade), microbiological reports, dur resistant disease.

We lack models that reliably predict 30-day postoperative adverse events (AEs) following spine surgery.

We externally validated a previously developed predictive model for common 30-day adverse events (AEs) after spine surgery.

This prospective cohort study utilizes inpatient and outpatient data from a tertiary academic medical center.

We assessed a prospective cohort of all 276 adult patients undergoing spine surgery in the Department of Neurosurgery at a tertiary academic institution between April 1, 2018 and October 31, 2018. No exclusion criteria were applied.

Incidence of observed AEs was compared with predicted incidence of AEs. Fifteen assessed AEs included pulmonary complications, congestive heart failure, neurological complications, pneumonia, cardiac dysrhythmia, renal failure, myocardial infarction, wound infection, pulmonary embolus, deep venous thrombosis, wound hematoma, other wound complication, urinary tract infection, delirium, and other infection.

Our group previously developed trformed in 59.1% of cases, which was comparable across cohorts. There was good agreement between the predicted AE and observed AE rates, Area Under the Curve (AUC) 0.64 (95% CI 0.56-0.710). The incidence of observed AEs in the prospective cohort was 17.8% among the low-risk group, 23.0% in the medium-risk group, and 38.4% in the high risk group (p =.003).

We externally validated a model for postoperative AEs following spine surgery (RAT-Spine). The results are presented as low-, moderate-, and high-risk designations.

Allograft and polyether-ether-ketone (PEEK) radiographic, biomechanical, histological properties have been extensively studied and both spacers have their advantages and shortcomings. There are no comparative randomized or double-blinded spinal fusion clinical trials reported to date.

The study's primary objective was to prospectively investigate clinical and radiological outcomes in patients undergoing lumbar interbody fusions and randomized to receive either PEEK or structural bone allografts.

A prospective, randomized, double-blinded clinical trial was initiated at a single center.

A total of 138 patients were enrolled, randomized and 121 patients completed the study.

The primary clinical outcome parameters were scored from standardized patient-reported questionnaires. The severity of lower back and leg pain was evaluated using the 11-point Visual Analog Scale (VAS). The Oswestry Disability Questionnaire was used to evaluate chronic disability and activities of daily living. Health-related qualitcally significant improvement in all clinical outcome measures at the end of the study regardless of the randomization group.

Although allograft-assisted surgeries may have reduced fusion rates, the study findings demonstrated that TLIF surgery with two different types of cages and in conjunction with rhBMP-2 resulted in similar radiological or clinical outcomes and a highly statistically significant improvement in all clinical outcome measures at the end of the study regardless of the randomization group.CTLA4-haploinsufficiency is a complex disease of immune dysregulation presenting with a broad spectrum of clinical manifestations. CTLA4-Fc fusion proteins such as abatacept have been described to alleviate immune dysregulation in several adult cases of CTLA4-haploinsufficiency. However, until now only few cases of pediatric CTLA4-haploinsufficiency treated with abatacept have been described. Here we present two pediatric cases of severe CTLA4-haploinsufficiency refractory to conventional immunosuppressive therapies that responded rapidly to treatment with abatacept. No side effects were observed during a follow-up period of 7-15 months. While one patient has successfully undergone HSCT the second patient continues to receive abatacept. Our cases demonstrate safe medium-term use of abatacept in the pediatric population.
