Unitherm-Cemcon's (Austria) Mono Airduct System (M.A.S.) is a multifuel rotary kiln burner used for clinker burning in cement plants. M.A.S. allows for burning different fuels together, works without interruption and produces good quality clinker. The nozzle outstream system creates on airstream, where the total primary air is guided in the outer burner duct to create a flame shape that can be changed to meet the requirements of different kilns. Improvements to M.A.S. and its operation are discussed.

- Abstract
This retrospective report focuses on the diagnosis of the Paxillus syndrome, based on two fatal cases of haemolysis following the consumption of Paxillus involutus . These mushrooms are still consumed regularly, despite earlier reports of life-threatening autoimmune haemolytic anaemia. Such cases are nevertheless rare, and thus far no toxin could be identified that causes this unusual form of mushroom poisoning. All these factors contribute to the difficulty in diagnosing the Paxillus syndrome. The following aspects support the diagnosis in the two cases presented here: Both patients consumed the mushroom oftentimes before, yet allegedly without ill effects. Symptoms occurred 2-3 h after the last consumption, exacerbating into circulatory collapse, multiorgan failure, and death. Disseminated intravascular coagulation was identified as cause of death by autopsy of patient 1. Patient 2 died of multiorgan failure, mainly hepatic. Our mycological analyses could identify the consumed mushroom in both cases as Paxillus involutus . Furthermore, we could exclude anticoagulants and several other drugs as trigger for the haemolysis by post-mortem toxicological analysis. However, findings in each of the two cases may have led to the haemolysis, independent of the consumption of Paxillus involutus . Patient 1 carried the anti-erythrocytic antibody, auto-anti-e. Patient 2 contracted chronic hepatitis C years prior to the current incident. Considering the rarity of the Paxillus syndrome, our findings suggest that these patients were particularly susceptible for haemolysis after consuming this mushroom over a prolonged period. Occurrence of the Paxillus syndrome may thus be restricted to regular consumers of Paxillus involutus mushrooms with an existing predisposition for haemolysis.

- Abstract
Background: In a large randomised trial in patients with seasonal allergic rhinitis (SAR), acupuncture was superior compared to sham acupuncture and rescue medication. The aim of this paper is to describe the characteristics of the trial's participating physicians and to describe the trial intervention in accordance with the STRICTA (Standards for Reporting Interventions in Controlled Trials of Acupuncture) guidelines, to make details of the trial intervention more transparent to researchers and physicians., Methods: ACUSAR (ACUpuncture in Seasonal Allergic Rhinitis) was a three-armed, randomised, controlled multicentre trial. 422 SAR patients were randomised to semi-standardised acupuncture plus rescue medication (RM, cetirizine), sham acupuncture plus RM or RM alone. We sent a questionnaire to trial physicians in order to evaluate their characteristics regarding their education about and experience in providing acupuncture. During the trial, acupuncturists were asked to diagnose all of their patients according to Chinese Medicine (CM) as a basis for the semi-standardised, individualized intervention in the acupuncture group. Every acupuncture point used in this trial had to be documented after each session, Results: Acupuncture was administered in outpatient clinics by 46 (mean age 47 ± 10 years; 24 female/ 22 male) conventionally-trained medical doctors (67% with postgraduate specialization such as internal or family medicine) with additional extensive acupuncture training (median 500 hours (1st quartile 350, 3rd quartile 1000 hours with 73% presenting a B-diploma in acupuncture training (350 hours)) and experience (mean 14 years in practice). The most reported traditional CM diagnosis was 'wind-cold invading the lung' (37%) and 'wind-heat invading the lung' (37%), followed by 'lung and spleen qi deficiency' (9%). The total number of needles used was higher in the acupuncture group compared to the sham acupuncture group (15.7 ± 2.5 vs. 10.0 ± 1.6)., Conclusions: The trial interventions were provided by well educated and experienced acupuncturists. The different number of needles in both intervention groups could be possibly a reason for the better clinical effect in SAR patients. For future trials it might be more appropriate to ensure that acupuncture and sham acupuncture groups should each be treated by a similar number of needles., Trial Registration: ClinicalTrials.gov: NCT00610584.

- Abstract
Purpose of the Study: From an initial group of 206 hips in 190 patients we carried out a retrospective clinical and radiological control of 74 hips in 72 patients covering a period of 20 years., Material and Method: Indications in 74 operated hips evidenced 48x(64.9%) primary and 26x(35.1%) secondary coxarthrosis. The average age at the time of operation was 53 years (37 years-68 years). All 72 patients with 74 hips received cement-free self- cutting Alloclassic screw cups of pure Titanium together with a cement-free square Alloclassic stem consisting of Titan- Aluminium-Niob alloy according to Zweymüller. Regarding the technique of operation we used the approach after Watson-Jones in the supine position. As prophylaxis against thrombosis 40% of the patients received derivates of heparine and 60% had anticoagulant therapy with cumarine. Prophylaxis against heterotopic ossifications were not carried out at this juncture in our department., Results: After an average post-operational examination lapse of 20 years we were able to examine 72 patients (37.9%) with 74 hips (35.9%) clinically and radiologically. Further classification of the 72 patients records 47 females and 25 males. The average age at the time of operation was 53 years and at the time of post-operational check-up to 74 years. For the clinical post-operational check-up (n=74) we used the Harris Hip Score. Further evaluation shows 12x(16.2%) excellent results, 26x(35.1%) good and 29x(39.2%) fair results. In 7 patients (9.5%) we had to observe poor results because of multimorbidity, although also in these cases stability of TEP had been achieved. The radiological post-operational check-up of the 74 stable hips (35.9%) shows an average excentric position of the head of 1.4 mm (0 mm up until 4 mm) compared with 1 mm after 10 years. Over an average of about 20 years we carried out an exchange of the inlay and the head because of excentric position of the head, which correlates to a rate of reoperation of 6.8%., Discussion: In 2000 and 2001 we published our 10 year results with cement-free Alloclassic screw cup and cement-free stem in 133 hips in 123 patients and compared our findings with those of other authors. After 10 years we saw only 3 % complications with cups and an overall re-operation rate of 6.7%. The 20-year-results show in all cases stable components of both cups and stems. 5 patients (6.8%) had to undergo re-operation with an exchange of inlay and head, whereby the components of the prosthesis themselves turned out to be stable. An average polyethylene abrasion of 1 mm after 10 years compares with a value of abrasion of 1,4 mm after 20 years. The 6.8% rate of re-operation after 20 years indicates the excellent results of the use of cement-free Alloclassic total endoprosthesis system of the hip according to Zweymüller., Conclusions: The biocompatible qualities of modern prosthesis material lead to a quicker and optimal bony incorporation of the pros- thesis components. The excellent 20-year-results show a broad indicative spectrum, component stability of the prosthesis in all patients and therefore encourage the further use of cement-free hip implants in the future.

- Abstract
Purpose of the Study: The aim of our retrospective study is to show that in cases of very serious degenerative alteration of the shoulder as well as massive Cuff arthropathy, there is a valid reason for the indication of an inverse prosthesis of the total shoulder joint. We therefore describe operation technique as well as evaluation of our own results, including complications., Material: From October 2000 to October 2005, 24 patients had 25 Delta prostheses implanted. All these 25 implantations were carried out by the author personally, using the Delta prosthesis, in Hybrid technique., Method: In all 25 implantations we used a lateral access by splitting the Deltoideus. We implanted the Glenoid component cement free, and we cemented the prosthesis of the Humerus in all our cases. After an average post-operational examination time of 3 years and 9 month, we examined clinically and radiologically, 23 patients (92%) with 24 implants. Pain, mobility and activity in every-day life were considered in the clinical post-operative check up., Results: Evaluation of pain showed that 14 patients (60,9 %) were free from pain and 9 patients (39,1 %) showed a great improvement in their medical state. In all cases we could clearly see that as far as mobility and activity in every-day life were concerned, a significant improvement hat occurred. The post-operative rate of complications showed the figure of 2 luxations (8 %). The luxation of the first patient could be repositioned in a non-operative way. The second patient was reoperated twice and we exchanged the shaft of the Humerus. In no instance did we discover any obstacle to the healing of wounds or any infections., Discussion: When the indication is carefully handled the inverse prosthesis of the shoulder is an excellent way of treatment of serious degenerative alteration of the shoulder joint and major Cuff arthropathy. The operation, which is technically demanding, should only be carried out by an operator experienced in shoulder operations. The rate of luxations can certainly be lowered with the accumulation of experience and strict adherence to the precise way in technique called for by this operation., Conclusion: With elderly patients the inverse shoulder prosthesis is a good alternative way of treatment of serious degenerative alteration of the shoulder and massive Cuff arthropathy.

- Abstract
Aim of Study: The aim of our study is to show the long-term results using the Zweymüller cementless Alloclassic stem., Method: In our retrospective study 133 from 206 cases (64.4%) were examined after 10.6 years. The examination was done clinically (Scheme after Merie d'Aubigné) and radiologically. The average age was 72 years (48-92 years) at the time of examination., Results: Intraoperative complications occurred in 3 cases (1.5%), 2 were temporary sciatic-nerve paresis and 1 was a stem fissure. Nine cases had been revised (6.7%). In four of these cases the inlay and the head had to be changed, in two cases mechanical loosening of the cup was found; furthermore, there were one removal of heterotopical ossification and one early infection. Stem problems appeared in only one case with deep infection and had been revised twice. There was neither stem sinking nor mechanical loosening in our series. The average polyethylene wear using a ceramic head with 32 mm diameter was 1 mm after 10.6 years. Clinically excellent results were found in 90% of the cases., Conclusion: The long-term results using the cementless Zweymüller stem with a rectangular transversal section and easy operation technique over 20 years are excellent Because of the cortical anchorage and the biocompatible titanium alloy the Zweymüller stem can be used in all femur forms and in different age groups.

Weissinger M and Helmreich C
- Abstract
Because our department of orthopaedic surgery deals with the cementless hip replacement for more than 15 years, we have performed a retrospective study and a critical analysis of our patients. In the time between 01. 05. 1987 and 31. 12. 1989 we implanted 206 primary cement-free total endoprostheses of the hip in 190 patients. After an average time taken for postoperative check-ups of ten years and seven months we evaluated 133 hips (64,6 %) in 123 patients (64,7 %) clinically and radiologically. The clinical postoperative check-up according to the score of Merle d'Aubigne demonstrated very good and good results in 90 % of our cases. After 10,6 years the radiological measurement showed an average polyethylene wear of 1 mm. The critical analysis of our patients amounted to 3 % of cup complications.The therapy with the reoperations of 9 patients (6,7 %) will also be discussed. In the discussion we are concerned with the results and problems of other authors, who are engaged with the cementless hip replacement. Summarizing we can declare, that the cementless Alloclassic cup to Zweymüller has a lot of advantages: ideal primary stability simple surgical technic optimal bony incorporation low polyethylene wear For the future we recommend a change of the headsize from 32 mm to 28 mm. In young and active patients we propose a metal-metal or a ceramic-ceramic pairing. Key words: cementless cup, primary stability, low polyethylene wear, 28 mm headsize.

- Abstract
The aim of our retrospective study is to show how very circumspect we are to use this method. The clinical symptoms of our patients were lumbalgia or lumboischialgia with or without neurological deficiencies. All these patients were resistent to conservative therapies. We accepted for operation only patients who suffered from protrusions and types of prolaps without perforation of the posterior longitudinal ligament. 179 operations on the vertebral discs were performed in our department between 01. 01. 1992 until 31.12.1997. Of this number 165 (92 %) were conservative nucleotomies (63 females and 102 males) and 14 patients (8 %) hat percutane nucleotomies and discos-copies (6 females and 8 males). The average age at the time of operation was 49 years (from 12 to 81 years) with patients who had an open operation, whilst the patients who had percutane nucleotomy had an average age of 42 years (26 to 56 years). The time span between postoperative checkups was on average about 40 months (3 years and 4 months). The shortest postoperative checkup period was 2 months and the longest 71 months (5 years and 11 months). Of the 14 cases mentioned we operated 9 patients in the segment L4/5, 4 patients in the segment L5/S1 and one patient in the segment L3/4. In 7 instances it was the right side that was injured and 7 times it was the left side which was injured. We performed all operations under general anaesthesia, the patient lying prone on the abdomen with lumbal lordosis raised as much as possible. We always used an X-ray picture enlarger on two planes. As far as subjective pain is concerned, an analysis of the findings gives the following results: 100 % improvement 6 patients, 80 % improvement 2 patients, 50 % improvement 3 patients, no improvement 3 patients. Five praeoperative existing motorial deficiencies had completely vanished postoperatively. As to eventual complications, we had one patient suffering from a lesion at the root of L4 on the right side with postoperative Spondylodiscitis L3/4 who was treated in a conservative way. When patient selection for this method is critically considered, the advantage of endoscopic operation lies in minimal invasion and rapid rehabilitation is associated with it.

- Abstract
Our retrospect study refers to the problem of improved flexibility of the hip joint, elongation of the leg as well as decrease of pain. Patients suffering from Coxa vara, a high positioned Trochanter and a short neck of the femur underwent triple osteotomy with a distal transposition of the Trochanter major. All 8 patients had a thorough clinical (according to the scheme by Merlé de Aubigné) and radiological postoperative checkup. The results were analyzed and showed an average increase of the length in leg of 1.9 cm and and average increase of capacity of abduction of 11 degrees. From these findings we draw the conclusion that triple osteotomy operation should be performed only on patients whose hip joints are free from arthrosis or show only insignificant symptoms of arthrosis.

Weissinger M and Helmreich C
- Abstract
In the submitted paper the authors describe in the introduction various possible ways of using autologous, homologous and heterologous transplants. A graft taken from the patellar ligament with two bone blocks from the patella and head of the tibia is, because of the great structural strength, the transplant of choice. As far as the surgical technique is concerned, the authors abondoned the open method because of its known disadvantages such as major arthrotomy and associated damage of proprioceptors of the knee joint. The authors are using the semi-open arthroscopic method, whereby artroscopic methods are definitely preferred. Positive aspects of arthroscopic methods are definitely preferred. Positive aspects of arthoscopy such as inspection of the joint, treatment of associated injuries, sparing of Hoffa's body and atraumatic surgical technique all are an advantage for the patient. An obvious advance in the surgical technique is the fixation of bone blocks by interference screws. This leads to early functional treatment using Lennox-Hill's orthesis and full burdening after 3-4 weeks. As most recent animal experiments confirmed that incorporation of the transplant from the lig. patellae is not completed before 12-14 month, it is no advantage to allow the patients to relieve the weight on the extremity. Shortening of the period of treatment reduces also trophic disorders on the operated extremity. Key words: instability of the knee joint, anterior cruciate ligament, plastic operation.

- Abstract
Between January 1, 1988 and December 31, 1993 125 operations of the anterior cruciate ligament were performed in 27 women and 98 men. 58 operations were on the left side, 67 on the right side. In the case - history an injury during leisure time was recorded in 84.8% of the patients, during sports activities in 94%. Of 125 patients 122 were examined by arthroscopy, three were operated by the semiopen approach. The mean age at the time of surgery was 29 years. The selection of the time of surgery indicates that 98% of the patients were operated as early secondary operations and as secondary operations (after 4 weeks). Of 125 patients 122 (97.6%) were examined repeatedly after a mean interval of 43 months. For evaluation the authors used a modification of the "Lysholmscore". According to the latter in 95% very good results were achieved. For evaluation of the stability the authors used a strict test, i.e. the Lachman test and KT-1000 measurements. As to severe complications, they recorded one deep infection, as to late complications there were two cases of arthrofibrosis with "cyclops syndrome". Key words: anterior cruciate ligament, ligamentoplasty.

- Abstract
In the submitted paper the authors give an account on the development of arthroscopy of the joint of the hand and comments on arthroscopic anatomy and technique of the procedures. In the authors' hospital the procedure is carried out under general anaesthesia, the patient lies on his back with the arm suspended in extension by the fingers, using a 3-5 kg weight. The authors use a needle arthroscope of Storz Co. with a diameter of 2.7 mm which is inserted into the joint from a dorsomedial approach. During the period between Jan. 1, 1990 and Dec. 31, 1993 14 arthroscopies of the joint of the hand were made in 10 women and 4 men, three times on the left and 11 times on the right hand. The mean age of the patients was 25 years and the mean follow-up period 2 years (8 months - 3 years). Revealed surgical findings: - chondromalacia 7 times; - damage of the disk twice; - rupture of the disk and chondromalacia 3 times; - synovitis once; - no pathological intraarticular finding once (cysta lunata without perforation). By surgery with irrigation and arthroscopic procedures such as resection of a ruptured disk and elimination of a defect of the authors were able to achieve improvement in mor than 70% of the patients.

- Abstract
Between January 1, 1989 and December 31, 1994 the authors performed in eight patients prolongation osteotomy of the neck of the femur with transposition of the greater trochanter. The patients comprised six women and two men, in four instances the left and four instances the right side was operated. The indications comprised in four patients congenital dysplasia of the hip joint with a shorter externity, is three patients Perthes disease, incl. in one patient postluxation m. Perthes, in one patient a state following fracture of the cervix. By Morscher's osteotomy prolongation of the extremity can be achieved and improved biomechanics of the hip joint. The method is recommended especialy younger patients with mild arthritic changes.

- Abstract
From 1st January 1988 to 31st December 1994, 105 patients were given 106 dynamic hip-screws in the Orthopaedic Department of the Public General Hospital, Zwettl. The average age at the time of operation was 77.6 years and the time lapse between the accident occuring and the operation performed was on average 31 hours. In 94.3% of the cases we could perform a closed reduction and in 88.7% we used a 135 degree-DHS. The four-hole plate dominated in 73.6% of the plates used. Internal complications totalled 23.6% out of which 9.5% of the patients died during their hospitalization. Here one must take note that the patients who died were of advanced age and multimorbid. We carried out clinical and radiological postoperative examinations on 54 patients (51.4%) with 55 operations (51.9%). The postoperative examinations took place on an average of 33 months (2 years and 9 months). The clinical postoperative examinations were carried out according to the Merle D'Aubigne system - 29 excellent, 58 good and 13 poor. The radiological postoperative examinations disclosed an ossian consolidation of 100% for 54 patients with 55 operations. Taking into account the classification of fractures according to the AO we find that the DHS is mainly used to treat fractures A 1/1-, A 1/2- and A 2/2-. With the exception of subtrochanteric fractures in which we have lately been using the Gamma-Nail, we have the DHS as a technically relatively simple and inexpensive implant in the treatment of pertrochanteric fractures of the neck of the femur.

- Abstract
Between Jan. 1, 1988 and Dec. 31, 1993 at the Orthopaedic Department of the hospital in Zwettl 12 patients with lateral dislocation of the patella were operated arthroscopically. In two habitual, in 10 relapsing and in one a new dislocation of the patella was involved. The patients were followed up clinically and radiologically, the mean follow-up period being 47 months. Every patient was subjected to complete arthroscopic examination of the knee joint. In the final stage of diagnostic arthroscopy an optical instrument was introduced from a medial retropatellar approach and lateral release was carried out. Subsequently from a 1.5 cm skin incision in the area of the medial facet of the patella a needle with a loop from the instrumentarium for sutures of the meniscus was inserted and from a medial parapatellar approach at both ends a PDS fibre, grade 0, was pulled out and by this thus developed U-shaped stitch medial capsulorrhaphy was achieved. In this way a total of 5-7 stitches were made. Extension of the U-stitches revealed on arthroscopy a satisfactory medialization of the patella. Further treatment involved application of a plaster tube in extension for 4 weeks: The authors discuss in the submitted paper the surgical technique and clinical and radiological results. Key words: dislocation of the patella, arthroscopy, lateral release.

- Abstract
Ever since percutaneous lumbar nucleotomy and discoscopy were introduced great hopes in this method were raised by specialists and patients. Based on the initial euphoric comments in the professional press, the authors started to use this procedure in 1992. During the period between Jan. 1 1992 and Dec. 31 1993 at the orthopaedic department of the General Hospital in Zwettel 69 operations of the disc were performed. The number comprised 62 conventional nucleotomies and 7 percutaneous nuc-leotomies combined with discoscopy. The mean follow-up period in patients with percutaneous nucleotomy and discocopy was 14 months (3-24). With regard to preoperative and postoperative development the therapeutic results were evaluated as follows. The authors proved strictly limited indications of this new surgical method and its inclusion in the therapeutic plan in protrusion and prolapse of the disc. As revealed by analysis, this method can be used to extend the hitherto valid therapeutic spectrum, if strictly limited indications are used. Key words: percutaneous nucleotomy, discoscopy.

- Abstract
The authors evaluate the problem of heterotopic ossifications as a complication of total endoprostheses of the hip joint. The classification into stages as elaborated by Arcque was used and compared with the clinical correlate. The authors compared the year 1989 when the total number of prostheses was 150 without prophylaxis of ossifications, with the year 1992 when the total number of endoprostheses was 200 with prophylaxis. In 94% of the patients starting on the second day after surgery to the 21st postoperative day 2 x 50 mg Indomethacin (2 x 1 capsule Indocin forte) were administered. As a gastroprotective drug the patients were given Ranitidine, 2 x 150 mg (2 x film tablets Zantac 150). Complications such as gastrointestinal complaints and skin exanthemas were observed only in 6 patients. Prophylaxis of thromboembolic disease was used in 1992 in 65% of the patients by anticoagulants and in 35% of the patients by administration of low-molecular heparin. This procedure proved a very simple, effective and safe method for prevention of para-articular ossifications: [table: see text]

- Abstract
High-molecular polyethylene is used in many technical spheres and in orthopaedics it is used in particular as a sliding component. In orthopaedic endoprosthetics it serves as a material for the manufacture of sockets, whereby polyethylene sockets can be anchored with our without cement. Morphological research corroborates the suspicion of inadequate static firmness of the polyethylene used and this may lead to abrasion and thus mechanical loosening of Endler's screw socket and subsequently also of the metal shank. At the orthopaedic department of the General hospital in Zwettel (Austria) between 1984 and 1987 113 Endler sockets were implanted in 101 patients. So far 41 reoperations were made in 39 patients. In 71% of the patients replacement by a non-cemented socket according to Zweymüller followed, in 17% by a cemented socket according to Müller. In 4 joints at the same time also the femoral component had to be replaced, in 13 shanks bone rarefaction in the area of the calcar femoris was detected. In shanks with removable heads the head was always replaced. Clinical evaluation of the operated patients was done according to the procedure of Merle d'Aubigné.

- Abstract
In the first part of our paper innovations as regards the non-cemented endoprosthesis of the hip joint by Zweymüller's method are described. As a special advantage the double cone of the socket is mentioned which as to its anatomical shape is close to the acetabulum and makes only slight resection of the bone on the floor of the acetabulum possible. At the Orthopaedic Department of the hospital in Zwettl between 1984 and 1987 more than 100 polyethylene Endler screw sockets were implanted. From the end of 1987 to the beginning of 1993 the authors used non-cemented endoprostheses as designed by Zweymuller. Based on the mentioned advantage of the new biconical socket, as suggested by Zweymuller, the authors implant this generation since the beginning of 1993. During the period from Jan.1, 1993 to Dec. 31, 1993 68 endoprostheses of the hip joint of the new type were used during primary operations. The follow-up of patients respected clinical and radiological criteria (pattern of Merle d'Aubigne). Of 68 patients 67 (98.5%) were followed up. In the present retrospective study in particular heterotopic ossifications were investigated, whereby the years 1992 and 1993 were compared. Key words: non-cemented total endoprosthesis of the hip joint, non-cemented biconical socket.

- Abstract
Total endoprosthesis of the knee joint of the LCS type reduce due to the mobile placement of the menisci and rotatable components the mechanical demands on anchoring in bone and thus contribute to satisfactory biological integration. During the period between June 1, 1989 and December 31, 1991 in the orthopaedic department of the general hospital in Zwettel 41 patients had 42 total endoprostheses (LCS) of the knee joint implanted. The group comprised 34 women and 7 men. All patients were checked and evaluated according to Hungerdorf's schema. The age range was 62 to 79 years with an average of 65.8 years. The follow-up period was 8 to 38 months, mean 21 months. The results as regards pain, stability, mobility, axis of the extremity and ability to walk were evaluated as very good and good. The authors discuss also postoperative complications. They did not observe loosening of cement-free components.
