Arthiritis

Hip arthritis is that form of arthritis that commonly causes pain, stiffness, and decreasing mobility of the hip joint. The quality of life and daily activities are affected due to pain and decrease in mobility. There are mainly two types of hip arthritis: osteoarthritis and inflammatory arthritis.

The most common form is osteoarthritis, in which cartilage in the hip joint wears down over time. Cartilage cushions the ends of the bones, enabling smooth movement of the bones. As the joints deteriorate, the bones begin to rub against each other, creating pain, stiffness, and limited motion. The possible causes of OA of the hip are age, injury to a joint, obesity, and/or genetics. Commonly, symptoms are worse following activity, better following rest; however, in time, the pain can become constant and severely impair mobility.

Inflammatory arthritis of the hip, such as RA, is an overactive immune system attacking normal joint tissue for chronic inflammation. This kind of arthritis does not only attack the articular surfaces but also the tissues surrounding the joint, leading to deformity of the joint and functional impairment if left unattended. Unlike in OA, pain and stiffness from inflammatory arthritis may be worse after morning rising or after periods of rest.

Both are treated with physical therapy, medications, and joint replacement surgeries in some advanced cases to relieve pain and restore functionality. Diagnoses, timing-wise, are therefore important in the preservation of hip health and limitation of joint damage.

Infections

Hip infections, also known as septic arthritis of the hip, are severe joint infections, which include symptoms such as intense pain, swelling, and limited movement of the hip joint. They generally are due to bacteria such as Staphylococcus aureus or Streptococcus that have entered the joint space through the bloodstream, following an injury, surgery, or infection somewhere else in the body. People with weakened immune systems, chronic illnesses, or recent joint surgeries are among those who are more at risk.

Infection of the hip can destroy joint tissue and cartilage with surprising speed and can have very serious complications if left untreated. Symptoms include hip pain that comes on suddenly and is often severe, swelling, redness, warmth around the joint of the hip, fever, and inability to bear weight. Of particular concern in children, hip infections could interfere with growth and permanently damage the joint.

Diagnosis is usually made by blood work, analysis of joint fluid, and studies of imaging, including X-rays or MRI, to confirm the presence and extent of infection. Treatment typically includes antibiotics to clear the infection and, in most cases, surgical drainage to drain infected fluid. Early intervention is imperative to avoid permanent joint destruction and preserve mobility. When the infection is severe, delayed treatment may lead to deformity of the joint that could necessitate hip replacement or reconstructive surgery for long-term mobility and function.

AVN

Avascular necrosis of the hip is also called osteonecrosis. The condition occurs due to a reduction or interruption of blood supply to the femoral head-a ball portion of the hip joint-resulting in the death of bone tissue. Because of a lack of blood supply, bones become thinner, weaken, and may collapse, thus causing hip pain, limiting mobility, and eventually leading to a loss of joint function. It can affect anybody, although AVN is more common between the ages of 30 and 50 years, apart from people who have risk factors such as the use of steroids, a habit of heavy drinking, trauma to the hip, or systemic diseases like lupus or sickle cell anemia.

Early-stage AVN may present with mild discomfort, but as the disease progresses, so does the pain, especially with weight-bearing, and may even be present at rest. Diagnosis is usually made on radiographic imaging such as X-rays, MRI, or CT, which will help identify changes in bone structure and the extent of damage.

Treatment options are staged for AVN, depending on the stage thereof. Early stages might include medications, while advanced stages may require core decompression, bone grafting, or hip replacement as surgical options to alleviate pain and improve functional joint use. Early diagnosis and intervention go a long way toward slowing the disease process in AVN and helping to preserve hip function.

Fractures

Most hip disorders result in serious fractures that affect mobility or quality of life, especially in older adults. The hip joint is a very crucial weight-bearing structure that may fracture due to trauma, falls, or other underlying conditions such as osteoporosis, which weaken the bone. Hip fractures can be broadly grouped into three categories: femoral neck fractures, intertrochanteric fractures, and subtrochanteric fractures. Each one of these types presents unique challenges with respect to treatment and recovery. For example, femoral neck fractures are intra-articular-that is, within the ball-and-socket joint-and their management usually requires very precise surgery, whereas intertrochanteric fractures are extra-articular  and tend to require specialized implants for the fixation of bone fragments.
