Active clinical trials for "Scoliosis"

In this study, which aims to evaluate the respiratory functions and respiratory muscle strength of individuals with Adolescent Idiopathic Scoliosis (AIS), it is planned to investigate the relationship between the respiratory parameters obtained and the severity, type, location of the curvature, rotation angle and wearing brace. The population of the study consists of individuals with AIS, and the sample consists of individuals with AIS followed in the Goztepe Prof. Dr. Suleyman Yalcin City Hospital, Orthopedics and Traumatology Clinic. For this purpose, it was planned to include at least 60 individuals with AIS, aged 10 years and older, with at least 20 degrees of scoliotic curvature, who applied to the clinic for the first time or came for control. Pulmonary Function Tests (PFT) will be applied to evaluate the respiratory functions of the participants involved, and intraoral pressure measurement (MIP, MEP) will be applied to evaluate the inspiratory and expiratory muscle strengths; The severity of the scoliotic curvature will be measured with the Cobb method on the same day's radiograph, and the axial rotation angle will be measured with the Scoliometer. IBM Statistical Package for Social Sciences Version 24 statistical program will be used in the analysis of the data. Continuous variables will be given as mean ± standard deviation, qualitative variables as numbers and percentages. Pearson Correlation analysis will be used for the relationship between the variables, Independent Samples t-test will be used for the comparison of independent groups, and statistical significance will be taken as p≤0.05 in all measurements. It is thought that this planned study will contribute to studies evaluating the respiratory functions and respiratory muscle strength of individuals with AIS, which have been designed in different types and reported different results in the literature. Evidence-based data obtained by determining the clinical parameters associated with these values are expected to guide clinicians in terms of being holistic in the treatment of individuals with scoliosis, and in which situations and for what purpose pulmonary rehabilitation approaches should be included.

Adolescent idiopathic scoliosis (AIS) is a common disorder of unknown etiology in which the vertebrae and discs gradually develop a curvature that is first detected in patients between 11 and 20 years of age. The deformity is 3-dimensional, with a coronal curve measured from radiographs by the Cobb angle . The Cobb angle measurement of scoliosis represents the sum of the angular wedging of each vertebra and disc between the superior and inferior end vertebrae . Although a small curve is well tolerated and does not require treatment, a large curve can progress to the point that it is cosmetically unacceptable, interferes with chest wall mechanics, and produces cardiac and pulmonary compromises. The natural history of AIS apparently includes 2 stages: the initiation of the curve and its subsequent progression. The factors responsible for the initiation of the curve are unknown, but the subsequent progression of the curve is clearly associated with the adolescent growth spurt . The primary risk factors for progression include age at onset and the magnitude of the curve; young patients with large curves are at the highest risk . Although numerous treatment methods have been recommended for patients with AIS, the only accepted treatment includes bracing for skeletally immature patients with curves between 25 and 40 degrees and operative correction with spinal fusion for patients with curves greater than 45 degrees. For many teenagers, the cosmetic and social concerns associated with bracing has caused compliance problems with wearing the brace and many patients only wear the brace at home . While operative intervention completely corrects the scoliosis or rib hump, it eliminates segmental spinal motion, and concentrates stresses at the ends of the fusion potentially leading to disc degeneration and back pain. Despite satisfactory short-term results of operative instrumentation and fusion, a less invasive technique preserving more motion with a smaller scar represents a major improvement. Realizing this goal is contingent on treating curves early, before they progress to an irreversible deformity, and when there is still enough residual growth and remodeling potential. ApiFix Ltd has developed a novel implant for less invasive treatment of AIS. The MID-C system is designed to correct the deformity step by step along a period of time, giving the skeletal and soft tissues time to accommodate any incremental correction. The MID-C System inherent benefits are: Only two screws are used Incision size is much smaller Simpler operation with shorter operative time Less complications (attributed to the three points above). Minimal spinal mobility loss. All the device components are made of materials well accepted in the orthopedic field and are fully biocompatible (see Investigator Brochure). The unique concept of the system and the materials used may provide favorable results as follows: Smaller scare, quicker healing period and better spine mobility over the years. This study is designed to demonstrate that the MID-C System is safe and effective.

The EOS® imaging system, a new imaging modality which offers low dose, weight bearing and full body X-ray imaging, requires a new standing position where patients put their hands and forearms on the wall vertically for stability. Although this method provides enough support for the patients during the extended X-ray acquisition time, its impact on the postural balance and sagittal profile of the spine and sacro-pelvic parameters has not been evaluated. The goal of this study is to identify the impact of patients' arm positioning on the sagittal profile and postural balance of the patient and subsequently propose a standardized method for full spine X-ray acquisition in the EOS® imaging system.

It is current practice for children who have surgery for early onset scoliosis (EOS) to be treated with insertion of extendable implants known as growth rod systems. This allows the growth potential of the child to be maximised during the period of growth. However, the child must undergo an average of 6 further surgeries to lengthen the rods every 6 months. Sometimes this may continue for several years. This requires repeated general anaesthesia and places the patient at risk of complications as well as on-going costs to the hospital with each admission and theatre episode. Magec is a magnetic growth rod from Ellipse technologies (distributed by SurgiC). The rod is inserted in exactly the same way as the conventional growth rod systems. The base implants i.e screws and hooks remain the preferred choice of the user. The only change is that a different rod is used. There are several advantages to this device. Firstly, after the initial insertion, further lengthenings, unlike current systems, do not need to be carried out in theatre under a general anaesthetic. In contrast, they can be done in an outpatients setting with a non-invasive technique. The rods are lengthened using an external magnetic device. The lengthenings are done in a controlled manner using an age related growth guide. Thirdly, the change from a theatre based intervention to an outpatient procedure will have cost-savings. The investigators also believe that there will be psychosocial benefits to the child and family by the avoiding the stress associated with repeated surgery at such a young age. In terms of risk assessment the device does not place the child at any more risk than would be expected from inserting any of the existing systems. In the event of failure of the rods the worst outcome is a revision to conventional rods.

In the present retrospective study, it was hypothesized that application, in scoliosis surgery, of a protocol for blood and fluid management, based on goal directed fluid therapy, cell salvage and tranexamic acid, could lead to reduced allogeneic red blood cells transfusion. The patients will be enrolled in a retrospective observational study and divided in two groups. Patients in no protocol Group received a liberal intraoperative fluid therapy and patients in protocol Group received fluid therapy managed according to a stroke volume variation based protocol. The protocol included fluid therapy according to SVV monitor, permissive hypotension, tranexamic acid infusion, restrictive RBC trigger and use of perioperative cell savage.

The purpose of this study is to determine the effect of double end spinal instrumentation from the upper thoracic to the pelvis with sacro-iliac fixation on the gait of ambulating patients with pelvic obliquity 6 month after surgery.

The purpose of this study is to translate and culturally adapt the quality of life profile for spinal deformities (QLPSD) to Turkish language and test the validity and reliability of Turkish version of QLPSD in patients with adolescent idiopathic scoliosis.

The investigators collected retrospective data of severe (>80o) and rigid scoliosis patients who underwent preoperative traction before correction surgery from 2016 to 2018. The first group consisted of patients who underwent Cotrel traction exercises and second group underwent continuous-progressively increasing Skull Tongs Femoral Traction (STFT) traction. Posterior fusion was performed in all patients. Intraoperative parameters (blood loss, operation time and level instrumented) and radiologic change (initial, post-traction and postoperative Cobb Angle) was evaluated and analyzed
