Overview

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.
Hyperprolactinemia
Hyperprolactinemia is an abnormally elevated level of the hormone prolactin in the blood. Elevated prolactin can interfere with normal reproductive hormone function and may cause menstrual irregularities, infertility, reduced libido, erectile dysfunction, or unexpected milk production. Symptoms and effects depend on the degree and duration of prolactin elevation and its underlying cause.

Diagnosis

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.
Hyperprolactinemia
Diagnosis generally begins with a blood test measuring prolactin. Because prolactin levels can vary and may be temporarily elevated, testing may sometimes be repeated under appropriate conditions. Healthcare professionals review medicines and associated symptoms and may check thyroid function and other laboratory values. Pituitary imaging, usually with MRI, may be considered when prolactin remains elevated or a pituitary disorder is suspected.

Prevention

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.
Hyperprolactinemia
Many causes of hyperprolactinemia cannot be prevented. Reviewing medicines with a healthcare professional before making changes, managing thyroid and other systemic diseases, and seeking evaluation for persistent menstrual, fertility, sexual, or unexpected milk-production symptoms can help identify the condition early. People with symptoms suggesting a pituitary disorder should follow recommended testing and medical follow-up.

Risk Factors

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.
Hyperprolactinemia
Risk depends largely on the underlying cause. Factors may include use of medicines known to increase prolactin, pituitary disorders such as prolactinomas, thyroid disease, pregnancy, breastfeeding, and conditions affecting kidney or liver function. Persistent hormonal or reproductive symptoms may warrant evaluation, particularly when accompanied by visual symptoms or other signs suggesting a pituitary disorder.
