Postoperative osteomyelitis due to Mycobacterium fortuitum. A case report.

A rare case of osteomyelitis of the tibia caused by Mycobacterium fortuitum which developed after closed intramedullary Küntscher nail fixation is reported. After extraction of the nail, combination therapy with antituberculous drugs, ofloxacin, and interleukin 2 was undertaken and bony union was achieved. Since a bone cyst formed during union, curettage and conventional cancellous bone grafting were performed. The patient is now pain-free even with prolonged weight-bearing. The success of treatment in this case is in contrast to other reports of the disease.
