Clinical observations on Blauth's total endoprosthesis of the knee joint.

This article reports on 207 implantations of the Blauth hinged endoprosthesis of the knee joint. Follow-up was possible in 188 (91%) of the implanted cases. The results could be clearly evaluated with a comparison between the time before and after operation, by means of a four-point system. They were very good in 85% and good in 11% of the cases, with an average follow-up period of 33 months, maximum longer than 8 years. The rheumatoid patients showed somewhat better results than those with osteoarthrosis. One of the main features of the success of the implanation in our follow-up patients was the relief from pain. To date, neither aseptic loosening nor fracture of prosthesis has been observed. The follow-up results, based on clinical aspects and constructional characteristics of the model during an observation period as long as 8 years, were encouraging. There was convincing evidence that because of the efficiency and predominance of the Blauth endoprosthesis no modification of the model was needed for further implantations. Technical complications could be prevented by careful manipulation. However, infection was still the most serious complication, affecting predominantly rheumatoid arthritis patients [6]. It always caused troublesome problems in management and jeopardized the success of the arthroplasty. The patella syndrome was another postoperative problem, though it was less serious than infection.

[Suggestion for technical facilitation of Blauth's knee endoprosthesis implantation].

Unsatisfactory seats of the prosthesis in femur and tibia within our clinical and roentgenological materials have been analysed. Upon this basis, the authors suggest some technical improvements with implantation of Blauth's prosthesis of knee joint as follows: 1) Preoperative exact plan of bone resections according to a.p. and lateral X-ray films of knee joint with the aid of cut-out X-ray films of the prosthesis and/or of our test-apparatus of femoral shaft. 2) Ascertain the horizontal line of tibia with the help of a vertical line of tibial shaft drawn preoperatively. 3) It should be emphasized, that finger groping during operation is indispensable.

Moebius syndrome: report of case.

This is a review of diagnosis, etiology and abnormalities of Moebius syndrome. The Moebius syndrome is rare and the cause is still unclear. It presents a case of a premature newborn baby with Moebius syndrome, showing unilateral facial nerve palsy, asymmetry of facial expression, inability to tightly close the right eyelids, asymmetry of the angles of the mouth with frequent drooling, poor sucking ability, dysphagia, extremity abnormalities and other cranial nerve involvement (VIII, IX, X, XI). He also had hypoplasia of the pons, a heart defect, and bilateral cryptorchism. The baby died of apnea on the 41st day after birth.
