methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

Our colleague, L. G. Parsons', has briefly outlined the historical facts regarding a disorder of the skeleton bearing the various names-hereditary deforming chondrodystrophy, multiple cartilaginous exostosis, diaphysial aclasis (Keith) or Ollier's disease; and Brailsford' has recorded the radiological details of a similar condition under the term chondro-osteodystrophy. The disease produces a s...

Subungual exostoses and hyperostoses of the great toenail are a differential diagnosis of nail tumors. We present 3 cases of subungual exostosis/hyperostosis with secondary nail dystrophy: a 36- and a 37-year-old woman as well as an 8-year-old boy. Two of the 3 patients suffered from pain. The 2 female patients presented with the classic dorsolateral firm protrusion, while the child presented w...

A 61-year-old Japanese man underwent right total hip arthroplasty for hereditary multiple exostosis. At first presentation, he had suffered from coxalgia for a long time. On radiographic images, there was a gigantic femoral head, increased shaft angle, and large diameter of the femoral neck. He had also developed coxarthrosis and severe pain of the hip joint. The transformation of the proximal ...

INTRODUCTION Recent innovation in wetsuit technology has opened the way for year-round surfing/water sport along the UK coast. Resulting exposure to low water temperatures combined with wind chill have been associated with external auditory canal (EAC) exostosis, also known as “surfers’ ear.” This condition is characterized by multiple, bilateral outgrowths of temporal bone (Fig. 1) into the EA...

The subungual exostosis is a benign bone tumor on the distal phalanx of a digit, beneath or adjacent to the nail, often bringing in discussion many differential diagnosis. We present a 14-year-old boy with a cutaneous nodular lesion, painful to the easy touch on the latero-internal half of the nail of right big toe with extension in the cutaneous part of this. He suffered many treatments, espec...

Buccal exostoses are broad-based, non-malignant surface growth occurring on the outer or facial surface of the maxilla and/or mandible, found usually in the premolar and molar region. Etiology is still not established, but it has been suggested that the bony overgrowth can be because of abnormally increased masticatory forces to the teeth. They tend to appear in early adolescence and may very s...
