It was the purpose of this study to use static and dynamic baropodometry pre- and postsurgery in patients submitted to knee replacement with a mobile bearing. Baropodometric analysis was accompanied by clinical and subjective evaluation. Data obtained from the baropodometer revealed considerable oscillations occurring between pre- and postsurgery. Static examination showed a significant increase in the percentage of loading on the side treated that was not observed in the dynamic evaluation. An analysis of the Knee Society score showed a considerable increase in values between pre- and postsurgery similar to how the interpretation of correlations presurgery revealed statistically significant values between function and length of step, between pre- and postsurgery data for scores for function and length of step and Knee Score. The short-term results obtained are encouraging but only a long-term follow-up will be able to confirm the use of evaluating total knee replacement.

The present work deals with a series of 28 patients (a total of 31 hips) suffering from coxarthrosis in dysplasia of the hip. All patients had undergone arthroplasty where an autograft of cortico-cancellous bone was taken from the head of the patientís femur. In 21 of these hips the prosthetic components were not cemented while the other 10 cases were. The patients (average age 57 years 5 months) underwent radiography and were clinically evaluated using the Harris Hip Score. The average follow-up was 6 years and 7 months. In the 10 hips which had been cemented, the average pre-operative Harris Hip Score was 46.9 points (range 24-85) while it was 80.5 upon check-up (range 50-98). In the 21 hips which were not cemented the average pre-operative Harris Hip Score was 44.3 points (range 21-62) while, at the time of check-up it was 90.8 (range 60-100). Only in 3 cases (9.67%) did the cotyloid portion require reoperation because of mobilization. In all cases (100%) the graft integrated perfectly with the host bone. The present study provides encouraging data regarding the use of autografts of cortico-cancellous bone taken from the head of the femur during hip replacement in patients with coxarthrosis in dysplasia of the hip. No differences were seen between the cemented and non cemented prostheses.

A total of 62 patients submitted to the surgical treatment of subcutaneous rupture of the Achilles tendon were followed up after a period of time ranging from 2 to 8 years. End-to-end suturing and reinforcement plastic surgery obtained excellent clinical results in more than 80% of the cases, with complications which were principally inherent to scarring. There were no cases of rupture. In cases with a longer follow-up, ultrasound examination revealed aspects of fibrillate restructuring of the tendon.

The rare posterior form of instability syndrome of the shoulder is taken into consideration. A diagnostic protocol aimed at revealing posterior slipping of the humeral head following spontaneous movement or with stress is suggested; this involves semiological maneuvers, and the help of radiographs in specific projections and CT scan. As for treatment, the importance of physiatric treatment is emphasized, and surgery advised in young patients who do not benefit from conservative treatment. The authors prefer posterior capsulomyoplasty associated with posterior glenoplasty in forms of the pathology characterized by excessive glenoid retroversion. Finally, 4 personal cases are presented.
