Transient osteoporosis of the hip is a rare condition that causes bone loss temporarily in the superior section of the femur. It is mostly found in young or middle-aged men between the ages of 30 and 60, and women in their later stages of pregnancy or early postpartum period (following childbirth). The majority of patients present with a sudden onset of pain in the groin area.

Osteoarthritis

This causes lateral hip pain and is thought to be caused by inflammation of the trochanteric bursa. It often presents with pain which can radiate to the lateral knee when side-lying on the affected side or when sitting down for prolonged periods. It is investigated with ultrasound and then MRI if required.

This would be unusual to present initially in the hip region. It would also normally present with morning stiffness lasting over an hour and/or systemic symptoms of fatigue, fever or loss of appetite. The pain generally gets better after activity. X-ray features would include erosions or significant soft tissue swelling.

Rheumatoid Arthritis
QuestionChoice
This is the death of the femoral head as a result of vascular disruption. Symptoms are often similar to osteoarthritis with progressive pain on activity. Risk factors include steroids, trauma and radiation. In mild-to-moderate AVN, radiographs may demonstrate sclerosis and changes in bone density. In advanced disease, bone deformities, such as flattening, subchondral radiolucent lines (crescent sign), and collapse of the femoral head, are evident.

A 69-year-old woman who has been taking oral steroids for the last year for giant cell arteritis presents with progressive pain in her left groin. The pain started insidiously and has been getting worse for the past two months. On examination, movement of her hip is painful in all directions but there is no evidence of limb shortening or external rotation. A weight-bearing hip X-Ray shows a crescent sign.
