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 * * Patellar tendon rupture 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 band of dense fibrous connective tissue that connects muscle to bone. It sends the mechanical forces of muscle contraction to the skeletal system, while withstanding tension. Tendons, like ligaments, are made of collagen. The difference is that ligaments connect bone to bone, while tendons connect muscle to bone. There are about 4,000 tendons in the adult human body. Structure A tendon is made of dense regular connective tissue, whose main cellular components are special fibroblasts called tendon cells (tenocytes). Tendon cells synthesize the tendon's extracellular matrix, which abounds with densely-packed collagen fibers. The collagen fibers run parallel to each other and are grouped into fascicles. Each fascicle is bound by an endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and elastic fibers. A set of fascicles is bound by an epitenon, which is a sheath of dense irregular connective tissue. The who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 of the Achilles tendon usually occurs due to a sudden, forceful push-off movement, an abrupt dorsiflexion of the foot while the calf muscle is engaged, or direct trauma. Chronic degeneration of the tendon, often from tendinosis, also increases the likelihood of rupture. Common risk factors include fluoroquinolone or corticosteroid use, sudden increases in physical activity, inflammatory conditions such as rheumatoid arthritis, gout, and chronic overuse or improper training. Diagnosis is primarily based on clinical symptoms and physical examination, with imaging such as ultrasound or MRI used for confirmation when needed. Prevention may include stretching before activity and gradual progression of exercise intensity. Treatment may consist of sur ...

Biceps Tendon Rupture
A biceps tendon rupture or bicep tear is a complete or partial tendon rupture, 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. The characteristic finding of a biceps tendon rupture is the Popeye sign. Patients often report an audible pop at the time of injury as well as pain, bruising, and swelling. Provocative physical exam maneuvers to assess for a rupture include Ludington's test, Hook test, and the Ruland biceps squeeze test. Treatment and prognosis are highly dependent on the site of the injury described in further detail below. __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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Biceps Femoris Tendon Rupture
Biceps femoris tendon rupture can occur when the biceps femoris The biceps femoris () is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this ... is injured in sports that require explosive bending of the knee as seen in sprinting. 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, uncoor ... [...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.
