How were the prosthetics leg being casted traditionally?5 answersTraditionally, the prosthetic leg was casted using a thermoformed frame made of a thermoplastic material or a laminated material, which was then ensheathed by a covering material.
What is the traditional casting method of prosthetics?5 answersThe traditional casting method of prosthetics involves the process of casting a rod from a raw material by continuously drawing the material from a mold in the horizontal direction while solidifying it. Another method includes using a split mold to form a cavity, where a lower mold, middle mold, and upper mold are used. Additionally, a casting method involves inserting a melt around a control element and withdrawing the melt on cooling, with the control element becoming an integral component of the cast component. Another casting apparatus includes a mold with first and second mold segments, and a transfer device that transfers a core to the first mold segment and receives and transfers a casting. Furthermore, a method for preventing cracking and reducing cost in cast steel involves packing fluid sand into the hollow parts of hollow cores and removing the sand at the optimum timing after the cast steel starts solidifying.
What are the different types of fractures? Describe each.?5 answersFractures can occur due to traumatic force sustained by a participant with another body, the ground, or an object. There are four types of bone in the human skeleton, and the types of fractures that can occur are wide and varied. Fractures can be classified as open or closed based on visual inspection, and imaging modalities can further assess the type and displacement of the fracture. Children are more likely to heal faster due to a higher intrinsic rate of bone remodeling, but certain fracture types can potentially affect growth and development outcomes. Fractures in tight fractured reservoirs with low permeability are mainly in a vertical pattern, with different groups of fractures distributed at various inclination angles. The connectivity and development degree of fracture systems can vary. Convolutional neural networks have been used for the classification of automobile fractures into ductile, fatigue, and brittle types.
How does ortho braces works?4 answersOrthodontic braces work by applying targeted and precise pressure to the treatment area, allowing for the correction of teeth alignment. The braces consist of flexible panels made of breathable elastic fabric, such as perforated neoprene or AIRPRENE, which are secured around the torso using closure structures. In the case of orthopedic braces, adjustable strap loops, sliding rings, and a shank embedded in the main panel are used to provide compressive forces to the treatment area. For orthodontic braces, a system of clamps and wires is used to attach the braces to the teeth and facilitate the movement of the wire along the teeth. Additionally, orthodontic braces may have brackets with a diamond-shaped tie-wing configuration that allows for multiple force vectors in different directions, reducing the time and effort required for installation and adjustment. Overall, orthodontic braces work by exerting pressure on the teeth to gradually move them into the desired position.
How is rehabilitation of fracture healing in osteoporosis?4 answersRehabilitation of fracture healing in osteoporosis involves a combination of medical treatment, nutritional interventions, and physical rehabilitation. Exercise is an important component of rehabilitation, as it can increase bone density and prevent postmenopausal bone loss. Multi-modal exercise is strongly recommended for reducing pain, improving physical function, and enhancing quality of life post-fragility fracture. Outpatient physiotherapy has a stronger evidence base for hip fractures compared to vertebral fractures. Nutritional care after fragility fracture is also crucial for improving morbidity and mortality outcomes. Education plays a role in increasing understanding of osteoporosis and utilization of rehabilitation services. Rehabilitation interventions are inter-reliant, and further research is needed to investigate the interaction of exercise, nutrition, and other multi-modal therapies.
How can mobile education be used to improve the outcomes of patients with a fracture?4 answersMobile education can be used to improve the outcomes of patients with a fracture by providing patient education and engagement. The use of mobile device applications (apps) can deliver information regarding injury, treatment, and recovery for orthopaedic and other injuries, allowing patients to access relevant information at their convenience. Additionally, the adoption of mobile technology among older adults with fractures supports the feasibility and acceptability of electronic interventions in this population. Point-of-care educational apps designed for surgeons and healthcare professionals can also contribute to better patient care by providing evidence-based information on topics such as osteoporosis, delirium, anticoagulation, and pain. The advancements in mobile technology enable personalized and up-to-date information, tracking of personal health data, patient reminders, and cost-effective communication, offering new opportunities for healthcare providers to integrate mobile health into clinical practice.
