Hyperbaric Oxygen Therapy for Primary Sternal Osteomyelitis

Abstract and Introduction

Abstract


Introduction: Primary osteomyelitis of the sternum is a rare condition, which accounts for 0.3% of all cases of osteomyelitis reported in the literature. The diagnosis requires a high degree of suspicion and confirmation by percutaneous biopsy. The treatment consists of resection of the periosteum and affected bone. Despite reports of successful conservative treatment using antibiotics alone, early surgical intervention plus bacterial control is the definitive treatment; it reduces morbidity, and is the most cost-effective approach for the patient. We report a case of primary osteomyelitis surgically treated with debridement and antibiotics, followed by hyperbaric oxygen therapy.

Case presentation: A 39-year-old Brazilian man without a significant medical history presented with primary osteomyelitis. After a normal chest radiograph and normal laboratory test results, he was treated with 2 weeks of nonsteroidal anti-inflammatory drugs. One month later a presumptive diagnosis of Tietze syndrome was made and he was prescribed prednisolone (60mg/day) for 3 weeks. The following month he presented to our service with swelling, redness, and warmth in the area between his left third and fourth ribs. Subsequent magnetic resonance imaging revealed a large collection of liquid (8.8×6.8×20.2cm) in his chest wall, between the body and the manubrium of the sternum. An area of soft, friable tissue with a large amount of pus was found in his sternum during surgical debridement. Subsequent treatment consisted of antibiotic therapy using metronidazole and cefotaxime plus hyperbaric oxygen therapy. On postoperative day 10 the incision was sutured. The patient was discharged on postoperative day 15 on a regimen of oral ciprofloxacin, and completed hyperbaric oxygen therapy as an out-patient.

Conclusions: The satisfying outcome of this patient reflects the quick action to promote surgical debridement and use of antibiotics, which are both recommended treatments. The closure of the wound in 10 days after debridement suggests that the hyperbaric oxygen therapy might have indirectly, but not conclusively, aided in the premature closure of the wound, avoiding a longer healing by second intention or muscle flap rotation closure.

Introduction


Primary osteomyelitis of the sternum is a rare condition, which accounts for 0.3% of all cases of osteomyelitis reported in the literature. It differs from secondary osteomyelitis, which results from complications of sternotomy. The primary form affects mainly young people and may be associated with intravenous drug use, trauma, or a central access catheter placed in the subclavian vein. The causative organisms are bacteria and, occasionally, fungi.

The onset is usually insidious, and the condition is slowly progressive, characterized by edema, redness, tenderness, mass development and pain radiating to the shoulder. The differential diagnosis includes cellulitis, abscess, and bone or soft tissue tumors. The diagnosis requires a high degree of suspicion and confirmation by percutaneous biopsy.

The treatment of primary as well as secondary sternum osteomyelitis consists of resection of the periosteum and affected bone. Unless grossly infected, the posterior periosteum must be kept intact to preserve the mediastinal integrity. Despite reports of successful conservative treatment using antibiotics alone, early surgical intervention plus bacterial control is the definitive treatment; it reduces morbidity, and is the most cost-effective approach for the patient. After debridement, options described in the literature for wound closure are secondary intention closure or muscle flap rotation. We report a case of primary osteomyelitis surgically treated with debridement and antibiotics, followed by hyperbaric oxygen therapy (HBOT).
