Filter by:The purpose of the study is to examine the changes in function and performance biomechanics in patients undergoing spinal fusion corrective surgery for adolescent idiopathic scoliosis (AIS).
A multicenter, prospective, non-randomized, single-arm observational study evaluating the Providence nighttime bracing system in patients diagnosed with adolescence idiopathic scoliosis.
OsteoAMP is a novel allograft bone graft substitute (BGS) that has been processed to retain multiple endogenous growth factors for use in spinal fusion. The study is designed to obtain a higher level of clinical evidence for OsteoAMP in spinal fusion procedures and not to garner FDA regulatory approval. This is a prospective, non-randomized, non-controlled, multi-center study of OsteoAMP in instrumented, posterolateral lumbar fusion (PLF) in patients with degenerative disc disease, degenerative spondylolisthesis (up to grade 1), and/or mild degenerative scoliosis, up to 25 degree curvature. Patients that are scheduled to undergo instrumented, posterolateral spinal fusion surgery as part of their medical treatment and comply with the study eligibility criteria will be given the opportunity to consent and be entered into the study.
Scoliosis is a disease that involves lateral and/or rotational deformity of the spine and can affect up to 4% of the population. Typically, surgery is considered when Cobb's angle, which is a measurement used for evaluation of curves in scoliosis on an anterior-posterior radiographic projection of the spine, is greater than 50 degrees in the thoracic region (40 degrees in the lumbar region) or when the curvature causes significant pain, or respiratory and cardiovascular restriction. Patient undergoing this surgical correction experience severe pain in the postoperative period and the management includes the use of opioid-based patient-controlled analgesia (PCA).
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.
Test the hypothesis to recruit larger motor responses to transcranial stimulation.
Measurement of bone length in subjects diagnosed with kyphosis and scoliosis using the Lunar iDXA x-ray scan.
The purpose of this study is to evaluate the effectiveness of chewing gum on reducing post-operative ileus and reducing post-operative gastrointestinal symptoms in pediatric patients undergoing surgical correction of scoliosis. This study would provide minimal risk to its study population, and has the opportunity to provide a benefit to patients undergoing scoliosis surgery. If shown to be effective, this could lead to changes and improvement of the post-operative course for pediatric scoliosis patients.
The hypothesis of this study is that moderate scoliosis patients have postural and kinematic differences (static and dynamic) compared with healthy volunteers and it is possible to characterize and quantify. The aim of this study is the detailed analysis of postural anomalies in moderate scoliosis patients compared with healthy volunteers
Surgical correction of scoliosis with instrumentation carries significant blood loss and needs for blood transfusion with its inherent risk and cost. In recent years, there is an increased interest in utilizing autologous blood as part of perioperative blood conservation strategy. The foremost mechanical methods of perioperative conservation of red blood cells including intraoperative cell salvage (ICS) and acute normovolemic hemodilution (ANH). They should be considered in all cases where significant blood loss (>1000 ml) or >20% estimated blood volume is expected, in patients with multiple antibodies or rare blood types and those who refuse allogenic blood products. Literature search has revealed that both cell salvage method and ANH utilized in elective surgeries are capable of minimizing allogenic blood transfusion respectively. Surgeries which are of significant relevance are aortic surgery, cardiac surgery and arthroplasty orthopaedic surgery. Combining the above two techniques such as in ATIS trial 2002 also shows that it is safe and significantly reduced allogenic blood requirements in aortic surgery. However till date, there is still lack of strong evidence that autologous blood transfusion technique is beneficial for scoliosis surgery in reducing allogenic blood transfusion. Hypothesis: The investigators hypothesize that the addition of ANH to ICS would confer additional benefit than using cell saver alone. By combining cell saver with hemodilution technique, the difference between pre-operative and post-operative Hemoglobin level will be smaller than using cell saver technique alone, hence minimizing the variation in perioperative Hemoglobin level - a predictor of allogenic blood transfusion.
