Tendon Rupture
Tendon rupture is a condition in which a tendon separates in whole or in part from tissue to which it is attached, or is itself torn or otherwise divided in whole or in part. Examples include: * Achilles tendon rupture * Biceps tendon rupture * Anterior cruciate ligament injury * Biceps femoris tendon rupture and Quadriceps tendon rupture * Cruciate ligament#Rupture * Patellar tendon rupture Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. Often there is sudden onset of pain and walking is difficult. In a complete rupture, the ability to extend that knee is decreased. A pop may be felt ... References {{reflist Injuries ...

Patellar Tendon Rupture
Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. Often there is sudden onset of pain and walking is difficult. In a complete rupture, the ability to extend that knee is decreased. A pop may be felt when it occurs. Injury to the patellar tendon generally requires a significant force such as falling directly on the knee or jumping from a height. Risk factors include patellar tendinitis, kidney failure, diabetes, and corticosteroid, steroid or fluoroquinolone use. There are two main types of ruptures: partial and complete. In most cases, the patellar tendon tears at the point where it attaches to the knee cap. Diagnosis is based on symptoms, physical examination, examination, and medical imaging. Small tears may be treated with rest and orthopedic splinting, splinting, followed by physiotherapy. Larger tears typically require surgery within a couple of weeks. Outcomes are generally good. Rates in the general population are not clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tendon Rupture -- Smart-Servier
A tendon or sinew is a tough, high-tensile-strength band of dense fibrous connective tissue that connects muscle to bone. It is able to transmit the mechanical forces of muscle contraction to the skeletal system without sacrificing its ability to withstand significant amounts of tension. Tendons are similar to ligaments; both are made of collagen. Ligaments connect one bone to another, while tendons connect muscle to bone. Structure Histology, Histologically, tendons consist of dense regular connective tissue. The main cellular component of tendons are specialized fibroblasts called tendon cells (tenocytes). Tenocytes synthesize the extracellular matrix of tendons, abundant in densely packed collagen fibers. The collagen fibers are parallel to each other and organized into tendon fascicles. Individual fascicles are bound by the endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and elastic fibres. Groups of fascicles are bounded by the e ...

Achilles Tendon Rupture
Achilles tendon rupture is when the Achilles tendon, at the back of the ankle, breaks. Symptoms include the sudden onset of sharp pain in the heel. A snapping sound may be heard as the tendon breaks and walking becomes difficult. Rupture typically occurs as a result of a sudden bending up of the foot when the calf muscle is engaged, direct trauma, or long-standing tendonitis. Other risk factors include the use of fluoroquinolones, a significant change in exercise, rheumatoid arthritis, gout, or corticosteroid use. Diagnosis is typically based on symptoms and examination and supported by medical imaging. Prevention may include stretching before activity and gradual progression of exercise intensity. Treatment may consist of surgical repair or conservative management. Quick return to weight bearing (within 4 weeks) appears okay and is often recommended. While surgery traditionally results in a small decrease in the risk of re-rupture, the risk of other complications is greater. ...

Biceps Tendon Rupture
A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle. It can affect any of the three biceps brachii tendons - the proximal tendon of the short head of the muscle belly, the proximal tendon of the long head of the muscle belly, or the distal tendon. __TOC__ Signs and symptoms When a tendon of the biceps brachii ruptures the muscle belly retracts, meaning that it goes from a lengthened position under tension at two attachments, to a shortened position with a single attachment. This shortened position forms a bulge which is referred to as "Popeye's deformity," due to similarity in appearance to the cartoon character Popeye. Other signs at the time of injury may include ecchymosis, swelling, and/or a sharp pain accompanied by an audible popping sound. The pain may persist for prolonged periods of time depending on the response to the individualized treatment plan. Distal tendon rupture will cause significant weakness with ...

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 joint swelling. Swelling generally appears within a couple of hours. In approximately 50% of cases, other structures of the knee such as surrounding ligaments, cartilage, or 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, 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 around the knee joint, reduced range of motion of the knee, and increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biceps Femoris Tendon Rupture
Biceps femoris tendon rupture can occur when the biceps femoris is injured in sports that require explosive bending of the knee as seen in sprinting Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an op .... If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle. Avulsion of the biceps femoris tendon is the complete pulling away of the tendon from the bone. This most commonly occurs where the long head attaches to the ischial tuberosity. Injuries to biceps femoris are more common than to other hamstring muscles. One theory for this is the fact that each of the two heads are innervated by different branches of the sciatic nerve. In states of fatigue or when the muscle is not fully warmed up, uncoord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadriceps Tendon Rupture
A quadriceps tendon rupture is a tear of the tendon that runs from the quadriceps muscle to the top of the knee cap. Signs and symptoms Symptoms are pain and the inability to extend the knee against resistance. A gap can often be palpated at the tendon's normal location. Diagnosis The diagnosis is usually made clinically, but ultrasound or MRI can be used if there is any doubt.

Cruciate Ligament
Cruciate ligaments (also cruciform ligaments) are pairs of ligaments arranged like a letter X. They occur in several joints of the body, such as the knee joint and the atlanto-axial joint. In a fashion similar to the cords in a toy Jacob's ladder, the crossed ligaments stabilize the joint while allowing a very large range of motion. Knee Structure Cruciate ligaments occur in the knee of humans and other bipedal animals and the corresponding stifle of quadrupedal animals, and in the neck, fingers, and foot. * The cruciate ligaments of the knee are the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). These ligaments are two strong, rounded bands that extend from the head of the tibia to the intercondyloid notch of the femur. The ACL is lateral and the PCL is medial. They cross each other like the limbs of an X. They are named for their insertion into the tibia: the ACL attaches to the anterior aspect of the intercondylar area, the PCL to the post ...
