This also applies to the lower leg, where lengthening is extremely difficult to predict, since short- the osteotomy is usually performed through the diaphysis, ening then occurs after the lengthening. This involves an osteotomy with the chisel, with preservation of the medullary vessels.

There is little risk of malignancy purchase raloxifene 60mg line menstruation on full moon, as malignant transformation has been estimated as less than one half of one percent. Appropriate orthopedic referral is indicated once the diagnosis is established. Most patients will develop problems relative to the bony involvement such as angular deformity, scoliosis, and limb length inequality. Pathologic fractures are managed in a conventional orthopedic fashion and healing is to be anticipated. Hemangiomatosis and lymphangiomatosis Hemangiomatosis and lymphangiomatosis are hamartomatous lesions of primarily the deep soft tissues that by their presence affect the size, shape, and length of the limbs. The lesions 137 Osteochondroma may consist primarily of hemangiomatous type tissue, or of tortuous dilated lymphatic channels, most likely arising from a common cellular origin (Figures 6. Clinically, patients so affected may present with pain in the extremity, but more usually as a result of regional gigantism, leg length discrepancy, and limb deformity. Well defined, rounded calcifications (phleboliths) may be seen on radiographs. In more involved cases an entire limb or an entire portion of the body may be involved with these slowly enlarging lesions. The clinical manifestations usually require a combination of plastic surgery and orthopedic surgery. Osteochondroma (osteochondromatosis) The basic lesion of osteochondroma or osteochondromatosis is a benign cartilage capped protrusion of osseous tissue arising Figure 6.

It is best conceived as the body’s attempt to form an additional bone in an abnormal location. It is likely that these lesions arise as an aberration in the direction of growth within the peripheral portion of the epiphyseal growth plate, producing a bone that then proceeds to grow along the path of least resistance. The lesions seen in the solitary form of osteochondroma and in multiple form of osteochondromatosis (multiple hereditary exostosis) are histologically identical in nature. The most common location for a solitary osteochondroma is the distal end of the femur and the proximal end of the tibia and humerus. Clinically the lesion is recognized as a hard, Miscellaneous disorders 138 non-mobile mass that is usually non-painful. Occasionally irritation of surrounding tissues will produce a localized bursitis or tendonitis. Radiographic appearance is characteristic, with a bony protuberance with the same bony texture as the adjacent bony tissue from which it arises (Figure 6.
