Injuries In Netball
Netball is a sport that has one of the largest female participation rates within the Commonwealth of Nations, Commonwealth, most popular in the United Kingdom, Australia and New Zealand, with more than 20 million athletes participating in the sport. Netball is a Ball Sports, ball sport played by two teams of seven players in which goals are scored by shooting the ball through a netted ring. Netball relies heavily on Endurance, muscular endurance and bursts of rapid acceleration to “break free” from an opponent as well as, sudden and rapid change of directions in combination with jumping to receive a pass, intercept a ball or rebound. The sudden stop-start motion of the game is what often leads to serious Sports injury, injuries in participants. Higher grade players, in both senior and junior competitions, are more susceptible to injuries than lower grade players, due to the high intensity and rapid pace of the game. An injury is most commonly defined as one that has occurred whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rachel Dunn Crop
Rachel () was a Bible, Biblical figure, the favorite of Jacob's two wives, and the mother of Joseph (Genesis), Joseph and Benjamin, two of the twelve progenitors of the tribes of Israel. Rachel's father was Laban (Bible), Laban. Her older sister was Leah, Jacob's first wife. Her aunt Rebecca was Jacob's mother. After Leah conceived again, Rachel finally had a son, Joseph (son of Jacob), Joseph, who would become Jacob's favorite child. Children Rachel's son Joseph (Genesis), Joseph was destined to be the leader of Israel's tribes between exile and nationhood. This role is exemplified in the Biblical story of Joseph, who prepared the way in Egypt for his family's exile there. After Joseph's birth, Jacob decided to return to the land of Canaan with his family. Fearing that Laban would deter him, he fled with his two wives, Leah and Rachel, and twelve children without informing his father-in-law. Laban pursued him and accused him of stealing his teraphim. Indeed, Rachel had taken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankle
The ankle, the talocrural region or the jumping bone (informal) is the area where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. The main bones of the ankle region are the talus bone, talus (in the foot), the tibia, and fibula (both in the leg). The talocrural joint is a Synovial joint, synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus. Structure Region The ankle region is found at the junction ...

Fracture
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress (mechanics), stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially, it is called a shear crack, slip band, or dislocation. #Brittle, Brittle fractures occur without any apparent deformation before fracture. #Ductile, Ductile fractures occur after visible deformation. Fracture strength, or breaking strength, is the stress when a specimen fails or fractures. The detailed understanding of how a fracture occurs and develops in materials is the object of fracture mechanics. Strength Fracture strength, also known as breaking strength, is the stress at which a specimen structural integrity and failure, fails via fra ...

Sprain
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movement. Sprains may be mild (first degree), moderate (second degree), or severe (third degree), with the latter two classes involving some degree of tearing of the ligament. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. An equivalent injury to a muscle or tendon is known as a strain. The majority of sprains are mild, causing minor swelling and bruising that can be resolved with conservative treatment, typically summarized as RICE: rest, ice, compression, elevation. However, severe sprains involve complete tears, ruptures, or avulsion fractures, often leading to j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although ...

Anterior Cruciate Ligament Injury
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. The most common injury is a complete tear. Symptoms include pain, an audible cracking sound during injury, instability of the knee, and knee effusion, joint swelling. Swelling generally appears within a couple of hours. In approximately 50% of cases, other knee joint, structures of the knee such as surrounding ligaments, cartilage, or Meniscus (anatomy), meniscus are damaged. The underlying mechanism often involves a rapid change in direction, sudden stop, landing after a jump, or direct contact to the knee. It is more common in athletes, particularly those who participate in alpine skiing, Association football, football (soccer), netball, American football, or basketball. Diagnosis is typically made by physical examination and is sometimes supported by magnetic resonance imaging (MRI). Physical examination will often show tenderness aro ...

Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. The term cruciate is Latin for cross. This name is fitting because the ACL crosses the posterior cruciate ligament to form an "X". It is composed of strong, fibrous material and assists in controlling excessive motion by limiting mobility of the joint. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 and 90° of knee flexion. The ACL is the most frequently injured ligament in the knee. Structure The ACL originates from deep within the notch of the distal femur. Its proximal fibers fan out alo ...

Meniscus (anatomy)
A meniscus (: menisci or meniscuses) is a crescent-shaped fibrocartilage, fibrocartilaginous anatomy, anatomical structure that, in contrast to an articular disc, only partly divides a synovial joint#Structure, joint cavity.Platzer (2004), p 208 In humans, they are present in the knee, wrist, acromioclavicular joint, acromioclavicular, sternoclavicular joint, sternoclavicular, and temporomandibular joints; in other animals they may be present in other joints. Generally, the term "meniscus" is used to refer to the cartilage of the knee, either to the lateral meniscus, lateral or medial meniscus. Both are Cartilaginous#Fibrocartilage, cartilaginous tissues that provide structural integrity to the knee when it undergoes tension (mechanics), tension and torsion (mechanics), torsion. The menisci are also known as "semi-lunar" cartilages, referring to their half-moon, crescent shape. The term "meniscus" is from the Ancient Greek word (), meaning "crescent".

Anterior Talofibular Ligament
The anterior talofibular ligament is a ligament in the ankle. It passes from the anterior margin of the fibular malleolus, passing anteromedially to insert at the lateral aspect of the talus at the talar neck , in front of its lateral articular facet. It is one of the lateral ligaments of the ankle and prevents the foot from sliding forward in relation to the shin. It is the most commonly injured ligament A ligament is a type of fibrous connective tissue in the body that connects bones to other bones.

Sprained Ankle
A sprained ankle (twisted ankle, rolled ankle, turned ankle, etc.) is an injury where sprain occurs on one or more ligaments of the ankle. It is the most commonly occurring injury in sports, mainly in ball sports (basketball, volleyball, and football) as well as racquet sports (tennis, badminton and pickleball). Signs and symptoms Knowing the symptoms that can be experienced with a sprain is important in determining that the injury is not really a break in the bone. When a sprain occurs, hematoma occurs within the tissue that surrounds the joint, causing a bruise. White blood cells responsible for inflammation migrate to the area, and blood flow increases as well. Along with this inflammation, swelling and pain is experienced. The nerves in the area become more sensitive when the injury is suffered, so pain is felt as throbbing and will worsen if there is pressure placed on the area. Warmth and redness are also seen as blood flow is increased. There is also decreased ability t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatigue (medical)
Fatigue is a state of tiredness (which is not sleepiness), exhaustion or loss of energy. It is a symptom of any of various diseases; it is not a disease in itself. Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states. However, fatigue is complex and in up to a third of primary care cases no medical or psychiatric diagnosis is found. Fatigue (in the general usage sense of normal tiredness) often follows prolonged physical or mental activity. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of cognitive activity which impairs cognitive ability, can manifest as sleepiness, lethargy, or directed attention fatigue, and can also impair physical performance. Definition Fatigue in a medical context is used to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
