Transient hip osteoporosis is a rare condition affecting the hip bone. It is typically characterized by bone marrow edema, which can lead to pain during weight-bearing and difficulty walking. In most cases, the condition tends to resolve spontaneously. It is most commonly observed in men aged 40-50 and pregnant women. While its exact etiology is not fully understood, possible risk factors include previous trauma, arthritis, vascular disorders (e.g., avascular necrosis), infections, alcohol and heavy smoking, hypothyroidism, low testosterone levels, vitamin D deficiency, pregnancy, and breastfeeding.
