Acute posterior dislocation of the shoulder: diagnosis.
The authors describe the clinical and radiographic findings of posterior dislocation of the shoulder by examining 19 cases observed at the Rizzoli Orthopaedic Institute between 1981 and 1990; of the total number of cases, 16 were acute and 3 inveterate, equal to 1.7%. After analyzing the pathogenesis of the lesion, which was due to direct trauma, indirect trauma, or which occurred during an episode of convulsions, the authors call attention to the rareness of the lesion, and consequently the little amount of knowledge of the clinical and radiographic elements characterizing it. Three varieties are distinguished: subacromial (or retroglenoid), subglenoid, and subspinous. Finally, the results obtained with non-surgical treatment, which always allows for recovery of the joint relationships and complete functional recovery, are reported.

Changes in growth of the ilium after sopraacetabular osteotomy. Long-term evaluation.
It is commonly known that in acetabuloplasty according to the Pemberton-Zanoli method the insertion of the graft produces an immediate increase in the height of the iliac wing which in successive months could become hypergrowth caused by the hyperactivity of the underlying Y cartilage. A total of 40 cases of insufficiency of the acetabular roof treated by this method were examined based on measurements on follow-up radiograms and an evaluation of the spino-malleolar distance until puberty. The clinical evaluation showed that in 82.5% of cases there is dysmetria that is less than or equal to 0.5 cm. An evaluation of radiograms at the end of growth of the ilium [correction of ileum] did not reveal significant variations between the hemipelvis submitted to surgery and the contralateral one either in cases treated by acetabuloplasty alone or in those in which intertrochanteric osteotomy was associated. Acetabuloplasty according to the Pemberton-Zanoli method is thus effective in the treatment of acetabular dysplasia at a young age, obtaining long-lasting effects and ones that do not cause dysmetria in the adult.

CKS knee prosthesis: biomechanics and clinical results in 42 cases.
From 1991 to 1993 a total of 42 CKS prostheses were implanted for the following reasons: osteoarthrosis (34 cases), rheumatoid arthritis (7 cases) tibial necrosis (1 case). At follow-up obtained after 17 to 41 months the results were: excellent or good: 41; the only poor result was probably related to excessive tension of the posterior cruciate ligament. 94% of the patients reported complete regression of pain, 85% was capable of going up and down stairs without support. Mean joint flexion was 105 degrees. Radiologically the anatomical axis of the knee had a mean valgus of anatomical axis of the knee had a mean valgus of 6 degrees. The prosthetic components were always cemented. The posterior cruciate ligament was removed in 7 knees, so that the prosthesis with "posterior stability" was used. The patella was never prosthetized. One patient complained of peri-patellar pain two months after surgery which then regressed completely.

Does total hip arthroplasty mean sensorial and proprioceptive lesion? A clinical study.
Total hip arthroplasty means sacrificing the joint capsule and the mechanoreceptors contained therein. Recent neurophysiological experiences seem to redefine the sensorial and proprioceptive role of the joint capsule in favor of the activity of the muscular mechanoreceptors, particularly in the area of the coxofemoral joint. The authors have examined the sensorial lesion caused by total hip arthroplasty in a group of 20 patients. Clinical testing was conducted prior to surgery, 7 and 40 days later. The tests were aimed at exploring the perceptive and proprioceptive activity of the hip, and showed marked decrease in all of the receptorial activity one week after surgery. After 40 days perceptive function was completely recovered, as the scores for tests conducted were the same as those obtained prior to surgery: proprioceptive activity was instead considerably improved, with significant changes in most parts of the tests. The authors conclude by observing that total hip arthroplasty does not cause permanent lesion of the perception of joint movement; furthermore, renewed coxofemoral mechanics allow for a better proprioceptive response with strengthening of static and dynamic antigravitational reactions.

Chondromalacia of the patella. Natural progression.
A total of 42 cases of patellar pain in subjects aged an average of 17.2 years submitted to arthroscopy are analyzed. Femoropatellar balance, where indicated, led to resolution of disorders with full resumption of sports activity. In the remaining cases chondromalacia showed the features of an affection with a spontaneously favorable course, confirming the common orientation towards conservative treatment. Arthroscopy is effective for a correct classification of cartilaginous lesions, and it is a good instrument to use when attempting to achieve recovery of patellofemoral joint when disorders are caused by a lack of equilibrium.
