Transient osteoporosis of the hip is a rare condition that tends to resolve on its own. It typically begins with bone marrow edema and can cause pain upon weight-bearing and difficulty walking. It most commonly affects men aged 40-50 and pregnant women. While the exact causes of this condition are not fully understood, it is associated with factors such as previous traumas, arthritis, vascular disorders like avascular necrosis, infections, alcohol and heavy smoking, hypothyroidism (underactive thyroid gland), low testosterone levels, vitamin D deficiency, pregnancy, and lactation.
