There are few reports on the surgical treatment of secondary malignancy arising from an osteochondroma on the lateral side of the proximal tibia. From March 2008 to December 2011, 3 patients were treated for a secondary chondrosarcoma from an osteochondroma of the proximal tibia involving the fibula. The operative procedure can be summed up as follows: (1) resection of the tumor including the f...

defined as prominence of the medial or vertebral border of the scapula.1-3 Clinically, decreased range of active shoulder movement, upper girdle muscle weakness, pain, or cosmetic changes may be observed. However, in many cases it is no more than an incidental physical sign. The classic etiopathology of winging of the scapula is serratus anterior muscle impairment, secondary to long thoracic ne...

Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the ...

A 15-year-old female had been followed in our department of pediatric radiology since the age of 11, in order to control a solitary osteochondroma (exostosis) of the right distal femur. Radiographs of the right distal femur (face-profile) and high frequency ultrasound studies (12-5 MHz) of this area were performed to assess the size of the lesion and the thickness of the cartilaginous cap. Foll...

We defined the characteristics of dysplasia and coxa valga in hereditary multiple exostoses (HME) by radiological analysis of 24 hips in 12 patients. The degree and effect of the 'osteochondroma load' around the hip were quantified. We investigated the pathology of the labrum and the incidence of osteoarthritis and of malignant change in these patients. Coxa valga and dysplasia were common with...

RATIONALE Three-dimensional (3D) printed templates can be designed to match an individual's anatomy, allowing surgeons to refine preoperative planning. In addition, the use of computer navigation (NAV) is gaining popularity to improve surgical accuracy in the resection of pelvic tumors. However, its use in combination with 3D printing to assist complex pelvic tumor resection has not been report...

A 16-year old male patient visited the hospital complaining of inguinal pain and internal snapping of right hip joint. In physical examination, the patient was presumed to be diagnosed femoroacetabular impingement (FAI) and acetabular labral tear. In radiologic evaluation, FAI and acetabular labral tear were identified and bony tumor associated with internal snapping was found on the posteromed...
