Therapy of enchondroma in long tubular bones

摘要

abstract_textpThe treatment of enchondroma in long tubular bones has been the subject of controversial discussions for several years. Whereas secondary malignancy is very rare when the enchondroma is located in a hand, a position near to the trunk represents a high risk of transformation into a chondrosarcoma. For an enchondroma in long tubular bones, authors recommend a whole variety of approaches ranging from regular controls to radical en bloc resection./ppBetween 1989 and 2001 we followed a concept of intralesional resection and cement filling. After an interval without recurrences, the cement was extracted andreplaced by a spongiosaplasty. Of 16 patients 12.5 suffered from an intralesional fracture in the course of the treatment, and 25 complained of persistent pain and loss of function after surgery. These complications led us to change our concept. Though there were two cases of secondary transformation into chondrosarcoma G1, we now prefer to keep the patients under close clinical and radiological control without performing surgery./p/abstract_text
