[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.

[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.

[Early general complications of total hinged knee prosthesis].

16 early deaths (within 24 hours) were observed after 758 knee joint replacements. In eight instances the patient died during the operation, and the other eight few hours later. The author discussed several possible causes: toxicity of the monomere, fat embolism hyperpressure in the medullary canal, hemorrhage. Several per and post operative precautions are recomanded.

The "caviar" madreporic knee prosthesis.

The madreporic ("caviar") prosthesis is a hinged knee prosthesis that can be inserted without the use of cement. The surfaces of the intramedullary stems are constructed with contiguous spheres one mm in diameter. These spaces are filled by bone trabeculae and haversian bone, providing permanent biologic fixation. Experimental madreporic knee arthroplasties in dogs show that bone probes these surfaces and produces solid attachments. Histologically, the trabeculae remain separated from the metal by a fine layer of fibrous tissue. The method of insertion of the prosthesis is simple. Preparing the epiphyses before any bone resection avoids the possibility of rotational positioning errors. The form of the intramedullary stems offers good positioning in the frontal plane. The analysis of an initial series of 15 cases shows results that are far from outstanding. The 2 deaths, the 2 cases of sepsis, and the recuperation of only mediocre motion can be explained, at least in part, by the advanced age of the patients and the poor bone quality of the rheumatoid patients. Nevertheless, this type of prosthesis has 2 important advantages. It avoids the complications from the use of acrylic cement and allows for a revision operation for cases of failed surface replacement designs. Obviously further experimentation with noncemented designs will continue and definitive studies will be reported later.
