[The therapeutic posture in desmoid tumor].

BACKGROUND: The desmoid tumor is a histologically benign neoplasm originating in muscular-aponeurotic structures and possesses a high tendency of local recurrence. The aggressive nature of the tumor obliges radical surgery to be performed principally in extra-abdominal tumors. METHODS: Twelve patients were treated from 1983 to 1993. The treatments performed prior to and after histologic diagnosis, the time of evolution when radical treatment was carried out upon diagnosis and the evolution after treatment were evaluated. RESULTS: Of the patients with desmoid tumor 8 were males with a mean age of 29.9 +/- 12.5 years. In eleven cases the presentation was as a tumor and was of pain in only one case. All the patients were surgically treated with a total of 27 interventions being carried out. Three patients also received pharmacologic treatment with tamoxifen, in 2 cases associated to sulindac. In two radiotherapy was used but not as a first line treatment. Following a mean follow up of 38 +/- 17 months no mortality has been registered but 5 patients are not disease free. CONCLUSIONS: The therapeutic attitude to the desmoid tumor should be radical surgery in both the primary tumor and the recurrences with medical treatment being performed in specific situations.

Treatment of Galeazzi fracture-dislocations.

Among 33 patients with a Galeazzi-type fracture-dislocation of the forearm, there were two children and 26 adults with a classic Galeazzi injury, and five patients with a Galeazzi-equivalent lesion. The worst results were obtained in type-I lesions. Closed reduction was primarily successful in children. The results of surgical treatment were much better in adults. It is advisable to treat this complex injury by anatomic reduction and internal fixation of the radial shaft fracture. Immobilization in a fully supinated position is recommended to reduce the dislocation of the distal radioulnar joint. Additional temporary radioulnar fixation with Kirschner wires is also necessary in cases of severe derangement of the distal radioulnar joint.

Osteochondritis dissecans of the patella. 12 cases followed for 4 years.

Osteochondritis dissecans of the patella in 9 patients (6 men, 3 women; mean age 19 years) was located in the median ridge and paramedial areas and was bilateral in 3 patients. All patients were initially treated conservatively with complete relief of symptoms in 5. In 7 patients fragments were excised and the crater was curetted and drilled. At follow-up after 4 (2-8) years, the patients had no restriction of activities and they had no pain.

[Nickel, chromium and cobalt release from a metal prosthesis in metal-sensitive patients].

Six rejected stainless steel hip prostheses that had been removed from 15 metal sensitive patient were immersed in different solutions in various containers and maintained at 37 degrees C in complete darkness. Two months later by means of atomic absorption spectrophotometric studies we were able to determine the amount of nickel, chrome and cobalt released in a saline solution. When the chromium oxide passivation coat of the metal prostheses is damaged by orthopaedic surgical implantation procedures the prostheses may rust, releasing metallic ions.

Internal fixation of fractures of the proximal end of the radius in adults.

Eight cases of internal fixation for fractures of the proximal end of the radius in adults are discussed. The reasons for this procedure, after considering the patient's age and activity and the type of fracture, was to avoid the sequelae of resection of the radial head. By following an appropriate technique, and provided that there are no compications, the results obtained have been excellent.
