Active clinical trials for "Scoliosis"

Scoliosis is a structural, tridimensional deformity of the spine. Characterized by lateral curvature and rotation of the vertebrae with functional limitations and cosmetic problems, idiopathic scoliosis, which accounts for 75% to 80% of all scoliosis, is the most common of all types. (1, 2) Surgical treatment is an effective way to correct severe spine deformity when the deformity progressively worsens and cannot be positively corrected by brace treatment. Spinal correction surgery is one of the most invasive surgical procedures and usually results in moderate to severe levels of postoperative pain. (3) Severe pain may induce implant complications such as construct dislodgement, broken instrumentation, and implant loosening which requires additional revision procedures These conditions adversely affect postoperative outcomes.(4) In the past several years, pain has become an important indicator for evaluating indicators of outcome and quality of life after surgery. Effective analgesia after surgery could improve patients' prognosis.(5) The erector spinae block is a recently described ultrasound-guided technique in which local anesthetics is injected into a fascial plane between the tips of the thoracic transverse processes and the overlying erector spinae muscle (longissimus thoracis).(6) The available evidence indicates that erector spinae block is effective in reducing opioid requirements and improving the pain experience in a wide range of clinical settings. They are best employed as part of multimodal analgesia with other systemic analgesics

This is a second study in a series of 3 studies. The first study assessed exercise compliance of scoliosis patients (adults and children). This study will look at different strategies to improve exercise compliance after a patient has completed an intensive course of treatment at Scoliosis SOS Clinic. It will be a randomised control trial. The control group will receive the regular exercise schedule that is created for the patients at the clinic, there will be two intervention groups, one using the exercise schedule with a diary and one using the exercise schedule with a mobile application. Compliance will be monitored through a questionnaire at their first and second check-up appointments which will take place every 3 months for a patient under the age of 18 and every 6 months for a patient who is 18 years old or over.

The present project aims to test the feasibility of a new management mechanism for inter-visit monitoring of adolescent patients with idiopathic scoliosis that improves the quality and safety of current orthopedic treatments using information and communication technologies (ICT).

Two recent studies showed that having two attending spine surgeons performing complex adult spine deformity surgery instead of one, decreased complications, unplanned surgeries within 30-days [Ames], 90-day readmissions, wound infection, pulmonary embolism/deep vein thrombosis and post-operative neurologic complications [Sethi]. However, both studies were retrospective and did not evaluate any cost-savings associated with having two spine surgeons instead of one performing complex spine deformity surgery. Most cost-effectiveness studies have used traditional accounting (TA) methods to determine costs. A few cost-effectiveness studies have used time-driven activity-based costing (TDABC) [Kaplan] in medicine [Au, Balakrishnan] and none in spine surgery. Objectives: The objectives of the study are (1) to determine if dual spine attendings reduce downstream costs compared to a single spine attending for complex spine surgeries using traditional accounting methods; and (2) to demonstrate an application of the TDABC method to evaluate the operating room phase during complex adult spinal deformity surgery and compare it to traditional accounting methods (TA).

Scoliosis is a condition in which there is curvature of the spine occurring in the lateral plane. It occurs in structural forms, characterized by a fixed curve, and "functional" forms, characterized by a flexible or correctable curve. By anatomic necessity, this lateral deviation is associated with vertebral rotation, such that when this deformity occurs in the thoracic spine, a chest wall deformity, or "rib hump," develops. Often there is a primary structural curve with an adjacent secondary compensatory curve. Most cases of structural scoliosis are idiopathic and have their onset in early adolescence. Females are affected more often than males, and their curvature is more likely to worsen. Lumbar fusion surgery is usually associated with massive blood loss. In clinical practice the surgeon might measure the visible peri-operative bleeding including intra- and post-operative drainage, but ignore blood component penetration into the tissues, residual blood in vertebral canal and loss due to haemolysis, which are also known as hidden blood loss. In patients with adolescent idiopathic scoliosis (AIS), surgical treatment involves a posterior approach with multi-segmental pedicle screw fixation. Although this procedure is generally considered safe with few surgical complications, there are considerable variations in fusion length, surgical time, and the extent of soft-tissue exposure. Consequently, perioperative blood loss can be substantial, and the use of intraoperative and postoperative RBC transfusions are frequently required. Patient blood management (PBM) is an evidence-based, multidisciplinary approach developed over the last 10 years focusing on improving patient outcomes as well as reducing the use of RBC transfusions. PBM includes several preventive measures to manage bleeding risks, reduce iatrogenic blood loss, and modify decision thresholds for the appropriate administration of blood therapy. All patients for elective surgery in whom blood loss is expected to be > 500 ml should have their hemoglobin checked pre-operatively and be investigated if they are found to be anemic. In the general population, anemia is defined as a hemoglobin less than 130 g. in men and less than 120g. in women by the WHO. It was proposed that the cut-off value/trigger be changed to hemoglobin more than 130 g for both men and women. Women with hemoglobin levels between 120 and 129 g. are not considered to be anemic according to the WHO definition, leaving them at a potential disadvantage when undergoing major surgery

There has been a growing trend amongst surgeons to use a construct for correction of scoliosis which involves segmental instrumentation with pedicle screws. Pedicle screw proponents cite greater curve control in all planes, which results in improved spinal curve correction. Some surgeons have noted due to the increased strength of the all screw construction that the rod is now the weak part of the spinal fixation. Although no evidence has been raised in regards to hardware failure there is a perception that a loss of balance in the sagittal plane is the result of flex in the titanium rod. A novel solution to the issue of rod flexibility is raised with the expedium super steel instrumentation which allows for greater stiffness than a 5.5 mm titanium rod with the same lower profile. This study aims to compare the new super steel technology with other established instrumentations used to correct spinal stenosis.

As a registry, the primary objective of the study is a data collection initiative. The study will collect clinical and radiographic outcomes of patients implanted with Medicrea's PSR. The secondary objective is to collect clinical and radiographic outcomes of patients with Medicrea hardware as a control cohort to the patient-specific rods.

The goal of the study is to analyze the influence of bracing on sagittal balance in scoliosis. In special we want to observe if there is a difference between two types of TLSO-brace, namely boston and cheneau. Retrospective analyses of Full Spine X-rays of patients who underwent bracing-therapy in the context of scoliosis. Different spinopelvic parameters will be analyzed: pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, spinopelvic angle, spinosacral angle, thoracal kyphosis. Four different X-rays will be reviewed for these parameters: Profile before bracing therapy Profile after initiation of bracing therapy Profile immediately after termination of bracing therapy Profile more than 3 months after termination of brace It concerns patients with idiopathic scoliosis (exclusion of congenital scoliosis, neuromuscular scoliosis and associated spondylolisthesis). Goal of the study is to check if treatment with TLSO-brace has a delordosing effect on sagittal balance (decrease of lumbar lordosis). The zero-hypothesis: TLSO causes no decrease in lumbar lordosis. Secondary goal is to compare the effect of the BOSTON TSLO-brace and otherwise the CHENEAU TLSO-brace on spinopelvic parameters and lumbar lordosis in special.

The aim is to assess the influence of asymmetric training on the locomotor system in sweep rowers. To analyse possible changes objectively, the axial position of the hull will be assessed using Moiré topography, and the symmetry of foot loading will be monitored with a pedobarograph. Furthermore, the Visual Analog scale and Cluster of Laslett will determine whether an asymmetric load can provoke pain in the lumbar region or cause a blockage in the SI joint. In the experimental study, there will be three different groups of participants. Selected sweep rowers will make the first study group. The second group will consist of scull rowers, and the last control group will consist of people with no experience with rowing. The selected participants will undergo the first measurement at the turn of the spring and summer seasons when intensive preparation for rowing competitions begins, in which sweep rowers train mainly on water and asymmetrically. The measurement results in the three groups will be further compared with each other to evaluate whether statistically significant differences can be found.
