Your Achilles tendon is a large band of tissue in the back of your ankle. You use it almost every time you move. But repeated stress can make the tendon more prone to injury. A complete tear through the tendon is known as an Achilles tendon rupture.
The anterior cruciate ligament (ACL) is one of the most common ligaments to be injured. The ACL is often stretched and/or torn during a sudden twisting motion (when the feet stay planted one way, but the knees turn the other way).
Avascular necrosis (also called osteonecrosis, aseptic necrosis, or ischemic bone necrosis) is a disease that results from the temporary or permanent loss of blood supply to the bone. When blood supply is cut off, the bone tissue dies and the bone collapses.
Low back pain can range from mild, dull, annoying pain, to persistent, severe, disabling pain in the lower back. Neck pain is pain that occurs in the area of the seven cervical vertebrae in the neck area.
A concussion is an injury to the head area that may cause instant loss of awareness or alertness for a few minutes up to a few hours after the traumatic event. Although they range from mild to severe, they are serious injuries that can harm the way the brain works.
This condition occurs when an abnormal growth of bone occurs where the plantar fascia attaches to the heel bone. It’s caused by long-term strain on the plantar fascia and muscles of the foot, especially in obese people or joggers.
As we age, the intervertebral disc may lose water and become dried out. As this happens, the disc compresses. This may lead to the deterioration of the tough outer ring allowing the nucleus, or the inside of the ring, to bulge out.
Lateral epicondylitis, also known as tennis elbow, is characterized by pain on the outside (lateral side) of the elbow. The pain is caused by damage to the tendons that bend the wrist backward away from the palm.
Mallet finger is a deformity of a finger caused when the extensor tendon is damaged. This generally occurs when a ball or other object strikes the tip of the finger or thumb and the force damages the thin tendon that straightens the finger.
Medial epicondylitis, also known as golfer's elbow, baseball elbow, suitcase elbow, or forehand tennis elbow, is characterized by pain from the elbow to the wrist on the inside (medial side) of the elbow.
Osteoarthritis, the most common form of arthritis, is a chronic degenerative joint disease that affects mostly middle-aged and older adults. Osteoarthritis is characterized by the breakdown of joint cartilage.
Osteochondritis dissecans (OCD) occurs when a small piece of bone and cartilage in a part of a joint separates from the bone around it. OCD is most common in the knee joint, but it can happen in other joints such as the elbow and ankle.
Jumper's knee, also known as patellar tendonitis, is a condition characterized by inflammation of the patellar tendon, which connects the kneecap to shin bone (tibia). The condition may be caused by overuse of the knee joint, such as frequent jumping on hard surfaces.
Runner's knee, also known as patellofemoral pain syndrome, is a condition characterized by dull pain around the front of the knee (patella), where it connects with the lower end of the thigh bone (femur).
The plantar fascia is a ligament-like band running from your heel to the ball of your foot. If your foot moves incorrectly, the plantar fascia may become strained. The fascia may swell and its tiny fibers may begin to fray, causing plantar fasciitis.
The posterior cruciate ligament (PCL) is also a common ligament to become injured in the knee. However, the PCL injury usually occurs with sudden, direct impact, such as in a car accident or during a football tackle.
The posterior tibial tendon runs along the inside of the ankle and foot. If this tendon is strained, your foot may hurt when it moves forward to push off the ground. Or you may feel pain when your heel shifts from side to side.
Repetitive motion injuries, also called repetitive stress injuries, are temporary or permanent injuries to muscles, nerves, ligaments, and tendons caused by performing the same motion over and over again.
Rheumatoid arthritis is a chronic disease that causes inflammation of the joints. The inflammation can become so severe that the function and appearance of the hands, as well as other parts of the body, can become affected. In the hand, rheumatoid arthritis may cause deformities in the joints of the fingers, making it difficult to move the fingers.
Scoliosis is a type of spinal deformity and should not be confused with poor posture. Spinal curvature from scoliosis may occur on the right or left side of the spine, or on both sides in different sections.
The shoulder joint is the most frequently dislocated major joint of the body - often caused by a significant force that separates the shoulder joint's ball (the top rounded portion of the upper arm bone, or humerus) away from the joint's socket (glenoid).
Although the shoulder is the most movable joint in the body, it is also an unstable joint because of its range-of-motion. Because the ball of the upper arm is larger than the socket of the shoulder, it is susceptible to injury.
A SLAP tear is an injury to a part of the shoulder joint called the labrum. The labrum is the cuff of cartilage that extends the socket part of the shoulder blade to better accept the ball end of the arm bone.
Fractures are breaks in the bone that are often caused by a blow or a fall. A fracture may be classified as a simple fracture (a thin fracture that may not run through the entire bone), or a compound fracture, in which the broken bone protrudes through the skin.
With synovitis of the hip, the synovium (lining of the joint) is inflamed (painful and swollen). With arthritis, a large amount of the articular cartilage (firm tissue covering the “ball” and “socket” of your hip) is damaged.
If you have thoracic outlet syndrome (TOS), the nerves or blood vessels just below your neck are compressed, or squeezed. It can be between the muscles of your neck and shoulder or between the first rib and collarbone.
Trigger finger is an irritation of the sheath that surrounds the flexor tendons. When you try to straighten your finger, it will lock or catch before popping out straight. If trigger finger is severe, your finger may become locked in a bent position.
A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. When the bursa becomes inflamed, the condition is known as bursitis.
Turf toe is a sprain of the big toe joint usually resulting from injury during sports activities. The injury is generally caused by excessive upward bending of the big toe joint from either jamming the toe, or repetitive injury when pushing off repeatedly when running or jumping.
