Osteochondroma in the Rib: A Case Report Reviewing Magnetic Resonance Imaging Findings

Osteochondroma is a benign bone tumor that is most commonly found in the extremities and is prevalent in adolescents, with a peak incidence before the age of 20 years. Herein, we present a rare case of a 33-year-old man with an asymptomatic tumor on the right anterior rib that was pathologically confirmed to be a rib osteochondroma after surgical excision. We describe the computed tomography and magnetic resonance imaging (MRI) procedures and highlight the importance of MRI as a critical diagnostic tool for osteochondroma.

Treatment of Infected Nonunion of the Femur with Marked Shortening by Compression and Gradual Distraction at the Nonunion Site: A Report of 2 cases / 대한정형외과학회잡지

The authors report two cases of successful reconstruction in infected nonunion of the femur involving marked shortening by compression and gradual distraction at the nonunion site using Ilizarov external fixator. At first, infection was controlled by radical excision & the administration of systemic antibiotics for four weeks and we also started compression at the nonunion site 3 days after operation. Autogenous iliac bone graft was added to strengthen the site of new bone formation lastly. In this report, the role of the compression seems to provide a good environment for distraction osteogenesis by focal necrosis and triggering inflammation. Compression and gradual distraction may be one of the treatment mordalities for nonunion of a long bone with massive bone loss or shortening, even infected.
