Filter by: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.
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).
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.
To evaluate the restoration and maintenance of thoracic kyphosis and coronal curve correction demonstrated through the surgical implantation of the K2M MESA Rail™ Deformity System as compared to literature reported outcomes for standard Cobalt Chrome (CoCr) rod systems in the treatment of Adolescent Idiopathic Scoliosis (AIS).
This is a study comparing pain control utlilizing one or two epidural catheters, along with a hydromorphone PCA, for analgesia following surgery for correction of scoliosis.
Adolescent idiopathic scoliosis surgery is an extensive procedure associated with significant blood loss frequently requiring the transfusion of blood. Tranexamic acid (TXA) is a synthetic antifibrinolytic (prevents breakdown of the blood clot) that has been used to extensively reduce transfusion in pediatric major surgery, including cardiac, craniofacial and orthopedic surgery. In this prospective randomized double-blinded study, the investigators wish to evaluate the hypothesis that TXA is more effective than standard of care at decreasing blood loss and blood transfusion perioperatively in children and adolescents undergoing idiopathic scoliosis surgery.
Objectives Primary objective: Determine if there is a clinically significant difference in percent Cobb curve correction in a low- vs. high-implant density cohort through a prospective randomized controlled trial. Design and Outcomes Randomized clinical trial of equivalence to test the efficacy and safety of low vs. high implant density instrumentation for spine deformity surgery in AIS patients with Lenke IA curve patterns. Interventions and Duration Intervention: low-implant density group or high-implant density group. Duration: 2 years. Sample Size and Population Target population: 10 to 17 years old with AIS who will undergo instrumented spinal fusion. Sample size needed (power = 90%) is 174 subjects with 87 in each group.
For AIS, the caring of patients with spinal deformities has a long and varied history. Severe spinal deformities can greatly reduce pulmonary and cardiac functions, which may lead to death from cardiopulmonary failure. Therefore, surgery is generally suggested when the curvature of the spine is greater than 45-50 degrees. The adverse psychological impact of orthoses treatment on patients and its poor compliance has been a well-recognised problem. Some orthotic research studies indicate that early intervention of spinal deformities is particularly desirable. Taking into consideration current clinical practices, if the curve is less than 20 degrees, even if the child is at a high risk of progressive spinal deformity during the age of 10-16 at puberty, treatment is nothing more than just observation. This project aims to combine clinical experience with textile and materials sciences to research and develop a posture correction girdle for adolescents with early scoliosis. As a result, this will reduce the future likelihood of brace wear or surgery. In this study, the eligible subjects will be given tailor-made posture correction girdles to wear it 8 hours daily. Monitoring and observation will be provided during the six months girdling period. Data will be collected before and after the girdling by X-ray radiograph for analysis, in order to comparison the spine curvature condition. Locomotion of the subject with and without wearing the posture correction girdle will also be reference.
Evaluate the long-term outcomes following operative and nonoperative treatment of childhood scoliosis.
The purpose of this study is to evaluate the relationship of A) The distal fusion level B) The total length of fusion and the post-operative range of motion in the unfused vertebral segments below the fusion in patients with Adolescent Idiopathic Scoliosis.
