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.
Genital Warts
Genital warts are sexually transmitted growths caused by certain types of human papillomavirus, or HPV. They may appear as small bumps or clusters around the genital or anal area and are often painless. HPV can be transmitted even when visible warts are absent. The HPV types that commonly cause genital warts are different from the types most strongly associated with some cancers.

InfectionDiagnosis
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.
Genital Warts
Genital warts are usually diagnosed by visual examination of the affected skin or mucosal areas. A healthcare professional may examine the size, shape, color, and distribution of the lesions. HPV testing is not generally required to diagnose typical visible genital warts. If a lesion has an unusual appearance, is pigmented, ulcerated, bleeding, or does not respond as expected, additional evaluation or biopsy may be considered.
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.
Genital Warts
HPV vaccination can help prevent infection with HPV types that cause genital warts and some cancers. Safer sexual practices, including condom or other barrier use, can reduce but do not completely eliminate HPV transmission because uncovered skin can also transmit the virus. Limiting the number of sexual partners and avoiding sexual contact when visible genital warts are present may also reduce exposure.
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.
Genital Warts
Risk is associated with sexual contact with a person who has HPV, including vaginal, anal, or oral sex. Having multiple sexual partners and not using barrier protection can increase exposure to HPV. A weakened immune system may make HPV infection more difficult to control. Genital warts can occur even when a person has had only one sexual partner and even when the partner has no visible symptoms.
