Chondromyxoid fibroma: a study based on 18 cases.

The authors report on 18 cases of chondromyxoid fibroma seen at the Institute of Orthopedics and Traumatology, University of São Paulo, from 1953 to 1990. A survey of the literature on chondromyxoid fibromas was conducted and radiographic analysis of all cases is presented, with a mean follow-up of 64 months. The surgical treatment employed in each case is discussed, with emphasis on the use of cement as an adjuvant. This procedure was used in 10 patients, who have been free of recurrence up to the present time.

[Surgical treatment of malignant bone neoplasms at level of the knee with wide resection and reconstitution with non-conventional endoprosthesis].

Forty-five patients with malignant bone tumors of the knee were submitted to wide resection and reconstitution of the joint with a custom made endoprosthesis. The mean follow-up was seven years and seven months. There were observed nine complications: in four cases the tumor recurred locally and in one case an artery was injured. The end result was considered good in 36 patients and poor in nine patients. The better results achieved in recent years were due to modifications introduced in chemotherapy for the osteosarcoma, the new system of staging of the bone tumors and new oncological and compartmental surgical techniques.

[Surgical approach to giant cell tumors of the distal radius].

The authors review 15 patients with giant cell tumor of the distal part of the radius in the period from 1980 to 1993. Pain was always present. The treatment of stage 2 with marginal resection and methylmethacrylate yielded excellent result. In the treatment of stage 3 the authors emphasize the need of wide resection. In these patients the best functional results were obtained with the use of vascularized proximal epiphyseal fibular graft, preserving some painless mobility of the wrist and forearm.

[Osteoblastoma: analysis of the treatment of 24 cases].

The authors study 24 patients with the histologic diagnosis of osteoblastoma treated from 1953 to 1996, with a mean follow-up of 33.4 months. Two were considered as a malignant osteoblastoma. Twenty-two cases were operated, and in 2 of these was performed only a selective embolization to pelvic and spine localization. It was discussed clinical and radiographic aspects and the response to treatment. It was obtained 20 good and 4 poor results.

[Current status of the treatment of high grade bone sarcomas].

The authors present a review of the changes occurred in the treatment of high grade bone sarcomas in the last 20 years. It was discussed the multidisciplinary approach for the local and systemic control of these tumors particularly the neoadjuvant chemotherapy that leads to an increase in the overall survival not only for the osteosarcoma but also for the Ewing sarcoma. They showed the possibilities for limb reconstruction after wide resection of the lesion that includes non conventional endoprosthesis and allografts.
