ABSTRACT

Case description: After normal delivery of her healthy child 20 days back, this 30-year-old woman presented to the authors with significant left hip pain and radiation to her left thigh limiting her routine activities. We are presenting the rare condition of transient osteoporosis of hip (TOH) with bone marrow edema which had been successfully managed with conservative treatment in the southern region of India.

Conclusion: We validate that our Indian pregnant women can face the challenge of this rare condition of TOH with bone marrow edema which can be treated well.

Keywords: Bone marrow edema Syndrome, Hip, Osteoporosis, Pregnancy, Transient.

INTRODUCTION

Transient osteoporosis of hip (TOH), or transient bone marrow edema syndrome (TBME), of unknown pathogenesis been reported well in the Indian subcontinent since 2009.1 This rare condition occurs in middle-aged men and younger pregnant women in their third trimester.14 It had occurred in a 50-year-old man as well in India4

We present the case of primigravida with TOH/TBME of left hip and well treated in the developing city of the Tamil Nadu State in India.

CASE DESCRIPTION

We are presenting a young woman who had been suffering with TOH and effectively managed. We authorize that our Indian pregnant women can get this rare condition of TOH with bone marrow edema. When diagnosed early, it can be treated well (Figs 1 to 3).

After normal delivery of her healthy child 20 days back, this 30-year-old woman presented to the authors with significant left hip pain and radiation to her left thigh limiting her routine activities. The pain started in the third trimester, but it was ignored and treatment was delayed. However, she pursued our conservative therapy with bisphosphonates and calcium (risedronate with calcium citrate maleate and cholecalciferol) for three months and recovered to her normal activities in this period. We are presenting this rare condition of TOH with bone marrow edema which had been successfully managed in the southern region of India.

DISCUSSION

Indian subcontinent had witnessed many pregnant women and middle-aged men are suffering from this disease in the recent two decades.5 In New Delhi there was a study had high incidence of men getting involved with TOH.6

Since it was first reported, it is a disease of the pregnant women well diagnosed clinically and radiologically through the magnetic resonance imaging (MRI). This condition produces severe hip pain and does limit normal activities. With a high index of clinical suspicion, MRI is the key element in diagnosing the disease. It causes effusion of hip joint and surrounding soft tissues. The conservative line of management including strict bed rest, analgesics with oral bisphosphonates completely cures the disease in a few months. The condition may produce stress fracture of the proximal femur if it is ignored and severe physical exhaustion is caused.7

The presentation in the hip is dull aching pain in the hip progressing over a period of time, with terminal limitation of movements. As classically reported, our patient had her hip getting involved but there are reports of involvement of spine, knee, ankle, and foot.6,8 The TOH may have migratory features. Both regional migratory osteoporosis (RMO) and TOH are considered part of the same spectrum. However, RMO involves the hip less commonly. It principally involves ankle, foot, and knee.1

Preliminary X-rays are most of the times normal in these patients, because it takes time for the osteopenia to develop. Typical radiographic findings are present within 4–8 weeks after onset of symptoms. But MRI is the proven diagnostic and rules out other causes of hip pain in the adult. Also, MRI shows distinctive features of bone marrow edema as early as 48 hours following the onset of pain. Hence it is better to take the MRI along with X-ray if we suspect the TOH clinically.1

As per the evidence, we advised her protective weight bearing. Oral bisphosphonates and calcium were given to her with regular follow-up.

Though the hip effusion is not so common, it was also seen in our case.

CONCLUSION

When an Indian woman in her last trimester of pregnancy experiences excruciating pain in her hip joints which is compromising her normal daily activities, she should be evaluated empathetically for TOH with bone marrow edema. Magnetic resonance imaging does support the diagnosis. Strict bed rest, analgesics, and bisphosphonates therapy will cure the disease fully.

We confirm that our Indian pregnant women can face the challenge of this rare condition of TOH with bone marrow edema which can be treated well conservatively.
