INJURIES & CONDITIONS – HIP JOINT



HIP OSTEOARTHRITIS


  • HIP PAIN . Hip Osteoarthritis (Hip OA), Cartilage Damage and the Ageing Hip
    – OA is usually a slowly progressive condition, where the thickness and smoothness of the cartilage gradually reduces.
    (1) Subchondral Sclerosis: hardening of the bone just below the cartilage surface. It shows up in the later stages of osteoarthritis. “Chondra” is another word for cartilage, so subchondral means “beneath the cartilage.” “Sclerosis” means hardening.
    (2) Osteophytes or Bone Spurs: To make up for the lost cartilage, the damaged bones may start to grow outward and form bone spurs.
    (3) Subchondral Cyst: a fluid-filled space inside a joint that extends from one of the bones that forms the joint. It may require aspiration (drawing the fluid out).
  • ORTHOINFO .
    – The ball and socket is covered with articular cartilage, a smooth, slippery substance that protects and cushions the bones and enables them to move easily
    – The surface of the joint is covered by a thin lining called the synovium which produces a small amount of fluid that lubricates the cartilage and aids in movement
    – In osteoarthritis, the cartilage in the hip joint gradually wears away over time. As the cartilage wears away, it becomes frayed and rough, and the protective joint space between the bones decreases. This can result in bone rubbing on bone.


FAIS – FEMORAL ACETABULAR (HIP) IMPINGEMENT


  • HIP PAIN
    – FAIS refers to early contact (impingement) between the bones of the hip during movement, due to a variation in shape of the bones of the hip joint (femur (thigh bone) and/or acetabulum (hip socket))
  • ORTHOINFO .
    – FAI is a condition in which extra bone grows along one or both of the bones that form the hip joint giving the bones an irregular shape. Because they do not fit together perfectly, the bones rub against each other during movement.


LABRUM TEAR


  • MAYO CLINIC . Acetabular Labrum
    – The smooth cartilage lining the socket merges into a ring of fibrous cartilage (labrum) that follows the outside rim of your hip joint socket.
    – Besides cushioning the hip joint, the labrum acts like a rubber seal or gasket to help hold the ball at the top of your thighbone securely within your hip socket
