Developmental dysplasia of the hip (DDH) or hip dysplasia is a condition that is seen in infants and young children because of developmental problems in the hip joint. The femur (thighbone) partially or completely slips out of the hip socket leading to dislocation at the hip joint. It is most common in the first-born baby with a family history of the disorder.
Hip and Groin Disorders
Hip and groin disorders are more common in athletes. They are caused by rapid acceleration and deceleration motion.
The rehabilitation time for hip and groin injuries is longer than most other injuries, therefore, early and accurate diagnosis is essential. The management of hip and groin injuries is complex due to the presence of multiple anatomic structures in that region. Moreover, the signs and symptoms of most hip and groin disorders are similar, making the diagnosis difficult.
Inflammatory Arthritis of the Hip
The inflammation of the joints is referred to as arthritis. Inflammation arises when the smooth lining called cartilage at the ends of bones wears away. In some cases, the inflammation is caused when the lining of the joint becomes inflamed as part of an underlying systemic disease. These conditions are referred to as inflammatory arthritis.
Hip pain, one of the common complaints, may not always be felt precisely over the hip joint rather in and around the hip joint. The cause for pain is multifactorial and the exact position of your hip pain suggests the probable cause or underlying condition causing it. Pain felt inside the hip joint or your groin area is more likely to be because of the problems within the hip joint.
Osteoarthritis of the Hip
Osteoarthritis, also called degenerative joint disease, is the most common form of arthritis. It occurs most often in the elderly. This disease affects the tissue covering the ends of bones in a joint called cartilage. In osteoarthritis, the cartilage becomes damaged and worn out, causing pain, swelling, stiffness and restricted movement in the affected joint.
Periprosthetic Hip Infection
A very small percentage of patients (less than 1%) who undergo hip replacement may develop an infection around the hip joint following surgery. This infection is called a periprosthetic hip infection. Your immune system is usually able to protect your body from bacteria or other infectious organisms by attacking it through the lymph system or blood stream.
Periprosthetic Hip Fractures
Hip replacement is a surgical procedure in which the damaged cartilage and bone are removed from the hip joint and replaced with artificial components. Any resulting fractures or breaks in the bone around the implant are called periprosthetic hip fractures. They usually occur around the stem of the implant and sometimes to the socket (acetabulum).
The hip joint is a ball and socket joint in which the head of the femur is the ball and the acetabulum forms the socket. The labrum helps to deepen the socket and provide stability to the joint. It also acts as a cushion and enables smooth movement of the joint. A hip labral tear is an injury to the labrum, the cartilage that surrounds the outside rim of your hip joint socket.
Avascular necrosis, also called osteonecrosis, is a condition in which bone death occurs because of inadequate blood supply to it. Lack of blood flow may occur when there is a fracture in the bone or a joint dislocation that may damage nearby blood vessels. Hip joint is most commonly affected; however, the knee and shoulder may also be involved.
