An avulsion fracture occurs when a tendon or ligament that is attached to the bone pulls a piece of the fractured bone off. Avulsion fractures can happen anywhere in the body but are most common in the ankle, hip, finger, and foot. They are more common in children than adults.

Cartilage is a tough, flexible tissue found throughout the body. Cartilage can become damaged as a result of an acute, sports injury. Cartilage injuries often involves the knees, although joints such as the hips, ankles and elbows can also be affected.

A dislocation injury is where a joint is forced out of normal position. Joints can be dislocated from injury. This usually happens from a fall, an auto accident, or sports. A dislocation is painful and immobilizes the joint. Common dislocated joints are shoulders, elbows, fingers, ankle, and hip.

A closed fracture is a broken bone that does not penetrate the skin. While a closed fracture does not penetrate the skin, there can still be severe soft-tissue injury associated with closed fractures. The most common closed fractures include: broken wrist, clavicle, arm and ankle fractures.

Ligaments are strong bands of tissue that connect bones at a joint. A sprain is an injury that causes a stretch or a tear in a ligament. Sprains may be classified as mild, moderate, or severe. A strain is a stretch or tear of a muscle or tendon.

The most common soft tissues injured are muscles, tendons and ligaments. These injuries often occur during sports and exercise activities, but sometimes simple everyday activities can cause an injury. Sprains, strains and contusions, as well as tendinitis and bursitis are common soft-tissue injuries.

Osteoarthritis is the most common form of arthritis. It occurs when the protective cartilage that cushions the ends of your bones wears down over time. Although osteoarthritis can damage any joint, the disorder most commonly affects joints in your hands, knees and hips.
