Overview

Scleroderma
Scleroderma is a group of autoimmune diseases characterized by abnormal hardening and thickening of the skin and, in some forms, changes affecting connective tissues and internal organs. The disease can vary considerably between individuals. Some forms mainly affect the skin, while systemic forms may involve the digestive tract, lungs, kidneys, heart, or blood vessels. Symptoms may include skin tightening, changes in skin color, joint stiffness, cold-sensitive fingers, digestive problems, or symptoms related to internal-organ involvement.
Avascular Necrosis
Avascular necrosis, also called osteonecrosis, occurs when reduced blood supply causes bone tissue to die. It most often affects the hip but can involve other joints such as the knee, shoulder, or ankle. Early disease may cause no symptoms, while progressive damage can produce persistent pain, stiffness, reduced movement, and eventually collapse of the affected bone or joint surface. The condition may develop gradually and can be associated with injury, certain medicines, medical conditions, or other factors that impair blood flow to bone.

Diagnosis

Scleroderma
Diagnosis is based on the medical history, physical examination, characteristic skin findings, and assessment for internal-organ involvement. Blood tests may identify autoimmune markers that support the diagnosis but do not establish it by themselves. Depending on symptoms, doctors may use lung function testing, chest imaging, heart evaluation, gastrointestinal studies, kidney tests, or other investigations. In selected cases, a skin biopsy or another tissue examination may help distinguish scleroderma from other disorders with similar features.
Avascular Necrosis
Diagnosis is based on symptoms, physical examination, medical history, and imaging of the affected bone. X-rays may appear normal in early disease, while magnetic resonance imaging can detect changes at an earlier stage. Additional imaging may help determine the extent of bone damage or joint collapse. Blood tests and other investigations may be used to identify an underlying condition or contributing cause, particularly when disease occurs at an unusual age or without an obvious risk factor.

Prevention

Scleroderma
There is no established way to completely prevent scleroderma because its exact cause is unknown. Early recognition of symptoms and regular medical follow-up can help identify organ involvement before complications become severe. People with relevant occupational exposures should follow appropriate safety measures. Avoiding smoking and managing associated cardiovascular, pulmonary, kidney, and other health problems may support overall health. Patients with established disease should follow individualized monitoring and treatment recommendations.
Avascular Necrosis
Some cases of avascular necrosis cannot be prevented, particularly when an underlying medical condition is responsible. Risk may be reduced by avoiding excessive alcohol consumption, using corticosteroids only as medically indicated, and discussing long-term corticosteroid exposure with a healthcare professional. Prompt assessment after significant joint or bone injury may be appropriate. People with medical disorders associated with osteonecrosis may benefit from appropriate management and monitoring for complications.

Risk Factors

Scleroderma
Risk varies according to the type of scleroderma. Factors that may be associated with increased risk include family history, other autoimmune disorders, genetic susceptibility, and certain environmental or occupational exposures. The disease is more common in women than men. Having an associated autoimmune condition or possible environmental exposure does not mean that scleroderma will necessarily develop.
Avascular Necrosis
Risk factors include prolonged or high-dose corticosteroid use, heavy alcohol consumption, previous fractures or joint trauma, and certain medical conditions affecting blood vessels or blood clotting. Associations have also been reported with disorders such as sickle cell disease, lupus, certain metabolic disorders, and some organ-transplant or cancer-related conditions. The risk varies according to the underlying cause, duration of exposure, and the location and extent of impaired blood supply.
