An inflammation of the hip bursae, fluid-filled cavities through which tendons pass. Bursae assist movement and reduce joint friction. Sometimes, bursae become inflamed and cause hip bursitis pain. They can become inflamed from overuse, an injury, rheumatoid arthritis, osteoarthritis, gout or from having had hip bursitis in the past.
A death of the tissue due to lack of blood supply. Hip avascular necrosis can lead to a weakening of the bones, small cracks and chips and eventual disintegration of the hip joint. Hip avascular necrosis can happen after a dislocated or fractured hip, in people who abuse alcohol or people who either abuse steroids or take them for long periods of time under doctor’s supervision. People with arteriosclerotic heart disease can also experience hip avascular necrosis. It is often a long-term, chronic condition.
A wear-and-tear disease that is characterized by a progressive wearing away of the cartilage that is intended to act as a cushion between the bones in a joint. As the protective cartilage is worn away by hip arthritis, bare bone is exposed within the joint. The friction of two bones rubbing against one another induces inflammation, which in turn, causes hip arthritis pain and stiffness. It runs in families, in people who are overweight and in people over the age of 50. Osteoarthritis is the most common form of hip arthritis.
Iliotibial Band Syndrome
Inflammation of the iliotibial band, a stretch of fibrous tissue that runs from the hip to below the knee, on the outer side of the leg. Hip iliotibial band syndrome typically occurs at the end of the thigh bone where there is a bursa (fluid-filled cavity) which should facilitate a smooth gliding motion. When inflamed, the iliotibial band does not glide easily, and hip iliotibial band syndrome is the result.
The labrum is a type of cartilage that surrounds the socket of ball-and-socket joints, such as the hip. It is designed to stabilize the joint and also allow for flexibility and motion. A tear in this ring of cartilage is a hip labral tear and can be caused in one of two ways. A degenerative hip labral tear is the result of overuse and wear-and-tear and can be seen in the early stages of hip osteoarthritis. An acute hip labral tear is caused by a fall, a sports injury or any other traumatic impact.
Hip impingement, also known as Femoroacetabular Impingement (FAI), occurs when bone spurs (calcified bony projections) form around the hip joint, causing the bone to pinch together when the hip is moved. The spurs are caused when the ball and socket of the hip joint are rubbing against each other, causing friction and damage to the bone and cartilage. Hip impingement can also cause hip labral tears and may be one of the early signs of hip arthritis.
A hip fracture is a partial or complete break or breaks in the femur (thigh bone) of the hip joint. One type is the ”femoral neck fracture,” which happensclose tothe hip joint and can interrupt blood supply to the head of the femur. This is a common fracture among older adults and can be related to osteoporosis. The “intertrochanteric hip fracture” occurs three to four inches from the hip joint. It does not impact blood supply to the bone and may be easier to repair.
