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.

Transient osteoporosis
QuestionChoice
This is is the death of the femoral head as a result of the vascular disruption. Symptoms are often similar to osteoarthritis. In mild-to-moderate AVN, radiographs may demonstrate sclerosis, although normally concomitant changes in bone density are noted. In advanced disease, bone deformities, such as flattening, subchondral radiolucent lines (crescent sign), and collapse of the femoral head, are evident.

Avascular necrosis (AVN)
QuestionChoice
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 typically investigated with ultrasound and then MRI if required.

Trochanteric bursitis
QuestionChoice
Pain in a joint which is worse with activity is typical of osteoarthritis. X-ray signs associated with osteoarthritis are nonuniform joint space loss, osteophyte formation, cyst formation and subchondral sclerosis.

Osteoarthritis

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.

An otherwise well 68-year-old female presents with pain after activity in her right groin. It started over a year ago and has been gradually worsening. Her GP sends her for a weight-bearing pelvic x-ray which reports loss of joint space, obvious osteophytes and subchondral sclerosis in the right hip joint.
