[Shoulder prosthesis].

In our department, 25 shoulder prostheses were laid in 24 patients. The main indication remains omarthritis with or without necrosis (13). Fifteen Neer's prostheses (13 total, 2 simple humeral ones) were laid. The posterior approach was chosen in 14 cases. Out of the 20 shoulders reviewed, 8 presented with preoperative muscle atrophy, 8 with no postoperative muscle atrophy, including 8 with posterior approaches. In 4 cases of posterior approach, postoperative atrophy of the infraspinatus muscle was noted, but these four patients were all satisfied or very satisfied. The analysis was carried out according to our grading (0 to 20) of Neer's prostheses. The overall results are excellent for simple humeral prostheses on traumatic lesions. In the other cases, the main benefit is obtained for shoulders in a stable state. The improvement remains poor for the mobility and function of the shoulder. The patients are satisfied on a whole, especially with the improvement of pain.

[Surgical treatment of anterior instability of the shoulder using an anteglenoid stop].

102 instable shoulders (either instable shoulders in athletes or true recurrent dislocation) have been stabilized by a Latarjet-type anteglenoid stop. In 3/4 of cases the patients were young men under 30 years of age, and 3/4 of the patients were athletes, most often of a high level. The diagnosis is based on history taking, as the clinical examination is virtually negative. The radiological assessment is easy: no arthrography, CT or other complex examinations are required. Bernageau's false-profile glenoid view shows lesions of the anterior edge of the glene in 95% of all cases. The operated patients were followed up for 6 months to 20 years (average distance 5 years). No recurrence of dislocation has been noted. Instability was experienced in only one case. Minimal pain is noted in 45% of all cases. A lower sporting performance than before the first dislocation was achieved in 7 cases, ie. about 10%. Normal articular motion is recovered except for outward rotation, which is generally decreased by about fifteen degrees. This perfectly settled, ironed-out procedure certainly is reliable. One point is worth discussing: does the formation of an intraarticular bony stop predispose to later arthrosis? This is what we are attempting to define for the patients we have operated first.

[Viability of new valvular homografts. Myth or reality?].

Use in cardiac surgery of aortic homografts as a valvular substitute is old and was specially developed in France by F. Fontan. In fact, these first allografts were non-viable and the results, in aortic position, were not better than current bioprosthesis. Renewed interest is related to the important notion of "viability" allowed by an immediate procurement (organ donors), preparation in nutrient medium RPMI with low doses of antibiotics and final storage at -196 degrees C (cryopreservation). We have reviewed our initial experience concerning 32 implanted homografts in children either in reconstruction of the right ventricular outflow tract (in many forms of congenital heart disease) or in aortic position. No mortality was observed. The only failure was due to an initial sizing mistake leading to an aortic valve replacement at 13 months. No late deterioration (mean follow-up: 12.5 months) was detected by echocardiography. These results seem to confirm other larger series (as O'Brien's, Brisbane, Australia). Biologic, histological and immunological assessments of "viable" homografts are discussed. The limits of the technique are reported.

[Elastometric study of the distal scaphoid ligamental complex and the scapho-lunar ligament].

Six wrists from fresh cadavers have formed the subject of a functional, histological and biomechanical study. This one has been realized by two methods: the one analytical, the other in the whole and in situ. The diverse experiences show up the pre-eminent role of the distal scaphoid ligamentous complex relative to the scapholunar ligament. This fact is in opposition to the generally admitted theories. It modifies the therapeutic approach to lateral carpal instabilities.

[Total hip prosthesis: what is the life expectancy? Survey of 430 prostheses with a 10 to 12 year follow-up in 253 cases].

In 1987 we made a review of all total hip prostheses inserted at Hopital Henri Mondor in 1974-1975-1976. These were of the metal-polyethylene Charnley-Muller or Lagrange-Letournel type (430 prostheses inserted in 349 patients). 178 hips were reexamined and 177 were lost to follow up. 61 patients had died. Overall, good results were found in 65% of patients reviewed - 12.5% had been reoperated upon. Although the newer models of prostheses are full of promise, none has stood the test of 10 years of use.

[Lesions of the rotator cuff of the shoulder. Surgical treatment. Apropos of 100 surgically treated cases].

After reviewing 98 cases with an average follow-up period of one to nine years, the authors describe the surgical indications for simple reinsertion of the supraspinatus muscle, reinsertion with muscle belly transfer, acromioplasty, and simple removal of intratendinous calcifications. The painful shoulder without tendinous tears confirmed by arthrography and with anterior involvement is easily improved by resecting the acromiocoracoid ligament, the anterior border and the inferior portion of the acromion. This anterior release can be associated with a curettage of calcifications if present. Tears of the supraspinatus can be reinserted on the greater trochanter without muscles transfer in 90% of cases. Satisfactory pain relief and function return while only very extensive tears with significant muscle retraction may require transfer of the muscle belly. Surgical repair of the rheumatologic should however, is performed rarely, and should be reserved for the infrequent cases that do not respond to medical therapy.

[Surgical opening of the carpal tunnel. Long-term results].

The authors present the results of surgery of a short series cases of compression of the median nerve. All cases involved idiopathic acroparesthesia. The surgical technique was the same in all cases: opening and resection of the large annular ligament, and opening of "loge de Guyon". All the patients were seen again by the same observer 1 to 6 years later (average time after surgery 2 1/2 years). The results were excellent as regards pain and subjective sensory disorders. In contrast, the muscular atrophy was little improved. The results of comparative electric examinations (19 cases) were improved, except where there were pre-operative signs of considerable denervation. In conclusion, the authors think that surgical opening should be restricted to patients presenting signs of serious denervation and to those who no longer benefit from medical infiltration treatment.
