Filter by:The purpose of this study was to assess pain (rest, activity, and night pain using the Visual Analog Scale), disability (neck using the Neck Disability Index; lumbar using the Oswestry Disability Index), and curvature (cervical, thoracic, and lumbar using the Spinal Mouse) in primary caregivers of children with cerebral palsy.
Spinal deformity is common in childhood and adolescence. Any spinal deformity, especially one that affects the thoracic spine, can affect lung function.The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. The investigators aimed to measure the diaphragmatic thickness in adolescents with increased thoracal kyphosis (thoracal hyperkyphosis) deformities.
Spinal deformity is common in childhood and adolescence, and can often present as scoliosis or increased thoracic kyphosis deformity with various etiologies.The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions.Any spinal deformity, especially one that affects the thoracic spine, can affect lung function.In the planned thesis study, investigators will measure the diaphragm thickness in adolescent idiopathic scoliosis patients with scoliosis deformities affecting the thoracic region, whether there is any relationship between the impact in the thoracic region and the diaphragm thickness, and the three-dimensional exercise (Schroth exercise-Barcelona Schroth therapy) applied in investigators' clinic for scoliosis, before and after the treatment of the diaphragm. Investigators aimed to show whether there is any change in thickness.
Idiopathic scoliosis of developmental age (AIS) is the most vertebral deformity in the adolescent population, with a prevalence of 1-3%. The treatment of AIS depends on the morphology and extent of the curve and the growth potential residual, can range from simple clinical-radiological monitoring, to the use of braces to, in the most severe cases, correction surgical correction. The indication for surgical correction of AIS depends on the location, extent and flexibility of the scoliotic curve and not least on the patient's age or, better, the skeletal age. The primary goal of surgery is to correcting the deformity by preventing its progression, preserving as many motion segments as possible; secondarily, the surgery aims to restore the coronal and sagittal balance of the spine.
Neuromuscular scoliosis (SNM) are deformities related to the impairment of normal function of the central nervous system (CNS) and/or peripheral nervous system (PNS) resulting in alterations to the of the functional unit represented by the integrated motor sequence (SIM). At the level of the spine, dysfunction of the SIM results in altered dynamic support of the spine. This results in a control of the trunk that is not harmonious due to the lack of effective mechanisms of muscle compensation. In particular, a greater degree of pelvic tilt with respect to the ground plane, with an increase in the degree of the so-called pelvic obliquity (OP), a fundamental parameter in walking and maintaining the seated posture. Spinal deformity causes severe alterations of the rib cage resulting in respiratory failure that often requires ventilatory supports and is associated with frequent airway infections, including pneumonias, often fatal. SNMs also express other comorbidities: cardiac (heart failure), neurological (epilepsy), nutritional that necessitate careful management multidisciplinary and especially anesthesiological evaluation for the peri-operative management. The surgical treatment of SNM constitutes a topic that is still debated due to both the bio-mechanical peculiarities of SNM and the clinical features, particularly comorbidities, that characterize this patient population. Compared with idiopathic scoliosis surgery, in SNM there is a higher rate of complications. To date, most of the complications are respiratory in nature (23%), followed by complications mechanical of the implanted surgical instrumentation (13%), and surgical site infections (11%). Furthermore, there is evidence that SNM surgery correlates with increased blood loss intraoperative. To date, it is recognized in the literature that the safest and most effective surgical treatment for SNMs is arthrodesis posterior instrumented with pedicle screws extended to the pelvis. In the years, mini-invasive surgical techniques have become increasingly prominent. invasive with the goal of reducing operative time, blood loss and complications themselves.
Aging-induced changes in the spine can lead to adult spinal deformity, causing a forward and/or lateral shift of the trunk. While mild cases may have compensatory mechanisms, severe deformities necessitate treatment. Surgery with instrumentation effectively corrects deformities, but complications are common. Precise pre-operative planning based on X-rays is essential. However, radiological imaging has limitations, including ionizing radiation exposure and static nature. Marker-based optoelectronic motion analysis systems offer potential benefits for dynamic spine assessment. This study aims to test the feasibility of using motion analysis systems to characterize spinal alignment and balance in patients with adult spine deformity. The primary objective is to assess the practical implementation, measurement capability, and resources required for motion analysis. Secondary objectives include investigating errors in absolute spinal curvature assessment and developing compensation strategies. The project will recruit 20 patients (non-operated and operated) seeking medical attention for adult spine deformities and 10 healthy controls. Participants will undergo biplanar imaging and motion analysis to capture static and dynamic spine alignment during common activities. The data will help build patient-specific musculoskeletal models, offering potential insights into improving surgical planning for adult spine deformities.
There are still a large number of severe spinal deformity cases which would keep progressing without treatment. These patients not only have severe appearance deformity, but also suffer from cardiopulmonary compression, reduced abdominal volume, and even spinal cord injury. It is crucial to provide safe and effective surgical intervention for these patients. The corrective surgery with 3-column osteotomy is reported to be an effective surgical strategy for severe spinal deformity. However, due to the great corrective stress on the rods, there is an increased number of patients requiring revision surgery due to rod fracture (3.7%-15%). In patients with 3-column osteotomy, the osteotomy area and the upper and lower adjacent segments are mostly stress-concentrated areas, and the rod is prone to fatigue fracture. Therefore, it is necessary to reinforce the osteotomy area and adjacent segments to reduce the risk of rod fracture. Our previous study found the risk of rod fracture could be reduced by using satellite rods with duet connectors or dominos. However, in the traditional satellite rod technology, the connection of the main rod and the satellite rod rely on the traditional single slot screw and duet connectors. The two are separated and not a whole in the mechanical structure. The stability of the fixation is relatively insufficient, and stil deserves room for improvement. Based on the traditional duet connectors, we further invent a novel dual-headed pedicle screw, which is an combination of traditional single slot screw and duet connector. Compared with the traditional duet connector, the novel dual-headed pedicle screw theoretically has stronger stability between the main rod and satellite rod, due to its integration of screw and connector. Hence, the purpose of this study is to verify the strong stability of the novel dual-headed screw by biomechanical study in cadavers performed with long spinal fusion (T12-pelvis) with L3 pedicle subtraction osteotomy (PSO). And to further investigate its effectiveness in severe adult spinal deformity patients receiving corrective surgery with PSO. If the biomechanical properties and clinical effects of the novel dual-headed screw have been confirmed, the promotion of the product has great prospects in the world. The severe spinal deformity patients would benefit from this study when they receive spinal corrective surgery with 3-column osteotomy, using satellite rods technology by this novel dual-headed screw.
Unplanned re-operation is one of the common negative indicators reflecting the quality and safety of surgery in the medical industry and has become one of the ten goals for the improvement of national medical quality and safety in China since 2022, while about 40% of unplanned re-operations in Peking University Third Hospital in recent years occur in spine patients of the orthopedics department. This project intends to establish a high-quality and sustainable ambispective disease cohort for spine surgery in Peking University Third Hospital based on the unplanned re-operations that occurred in the Orthopedics Department of Peking University Third Hospital from January 2012 to December 2025. The investigators further summarize and analyze clinical causes and risk factors of re-operations, aiming to explore scientific coping strategies and provide reference for continuous improvement of medical service quality.
