[Aseptic loosening of the Charnley prosthesis].

Out of 100 Charnley prostheses implanted for idiopathic arthrosis and followed up a minimum of 5 years after surgery, 59 were fixed, 24 were characterised by probable radiologic loosening of the femoral component, 13 by probable loosening, and 4 by possible radiologic loosening of the acetabular component. None of the patients was submitted to further surgery. Some of the features of the patients were found to be associated with a higher incidence of femoral loosening. In most of the cases loosening was minimal, only radiologic, and not clinically apparent, and numerous technical improvements in the use of cement and in the design of the prosthesis were introduced subsequent to the period when these patients were operated on.

[Total hip prosthesis according to Charnley. Review of our cases].

This is a follow-up study of 363 Charnley hip replacements out of 548 implanted from 1970 to June 1984. Clinical results, with a 2-year minimum follow-up (average 5 years, maximum 15 years) are excellent or good in 89.5% of the cases. In the group with minimum 5-year follow-up (average 7, maximum 15 years) the clinical results remain good to excellent in 89.2% of the cases. Radiographic results have been studied in the group with minimum 5-year follow-up. Component stability or radiographic loosening have been studied, taking into account the presence of radiolucent lines between bone and cement, between metal and cement, or based on component migration or positional shift. We have detected radiographic loosening in 11.5% of the acetabular and 13.5% of the femoral components. A correlation was sought between radiographic loosening and some clinical (diagnosis, weight, follow-up period) and radiographic (postoperative component position, polyethylene wear, cement technique, periosteal reaction, myositis ossificans) parameters. There is no strong relationship between radiographic loosening and clinical results, as 28 of 35 radiographically loose prostheses maintained excellent or good results. Finally, the results of a selected group of 29 hips, with a minimum follow-up of 10 years, is reported.

[Tuberous sclerosis: a multidisciplinary study of 15 cases].

Report of a multidisciplinary study of patients affected with tuberous sclerosis, 8 of them males and 7 females, with ages ranging from 19 months to 23 years; 11 of these cases were sporadic, while the remaining 4 cases lacked information regarding family data. The following skin signs were observed: Pringle's adenoma in 9 cases; achromatic spots in 9 cases; periungueal fibroma in 3 cases. One of the patients had a heart tumor. Two patients had borderline intelligence, while the other 13 were mentally retarded of varying degrees. Epileptic seizures were present in 13 patients, atypical absence and tonus crises were frequent. Three of the patients had had infantile spasms in the first year of life as the first neurological symptom of the disease. Computer assisted axial tomography was performed in 7 cases and was positive in all of them, by revealing intracranial calcifications even in 4 cases in which the standard X-ray pictures had been silent about this eventuality.
