[Current status of spinal injuries in winter sports].

Parallel with a marked escalation in the number of injuries of the skull, shoulder girdle and upper extremities in recent years, the incidence of spinal injuries has also intensified. This is due to an increase in speed and deceleration traumas, such as are particular to collision accidents. Of all patients with winter sports injuries at the Department of Traumatology at Innsbruck University Hospital, 4.9% have a spinal trauma. A retrospective ten-year study was undertaken to analyze the surgically treated spinal injuries out of overall winter sports injuries. Between 1982 and 1992 862 spinal injuries were surgically treated, 10.9% (94) of which were suffered in winter sports accidents. Of these winter sports injuries, 81.7% (76) were due to skiing accidents. The age group 15 to 25 years made up the largest contingent at 39.8% (37). Most spinal traumas (47.3%), whether suffered in winter sports or not, were located in the thoracolumbar region or the lumbar part of the spine, followed by 38.7% at the cervical vertebrae. Serious snowboard accidents are especially predestined for injuries of the cervical vertebrae. The age group 51 to 60 years also shows a trend to injure the cervical vertebrae; degenerative changes present in this age span cause a high percentage of accompanying neurological injuries. More than half (52.7%) of all surgically treated spinal injuries showed some loss or impairment of neurological function at the time of admission; 17.2% of these cases showed symptoms of a complete transverse lesion of the cord. 36% of all serious spinal injuries are accompanied by secondary injuries (such as craniocerebral trauma, thoracic trauma and other fractures).(ABSTRACT TRUNCATED AT 250 WORDS)

[The treatment of fresh anterior cruciate ligament ruptures in relation to age and level of sports activity].

Due to its exposure as well as a lack of securing muscles the knee is the human joint with the higher incidence of traumatic injury. The aim of this retrospective study was to illustrate our five-year results following conventional and surgical therapy and to relate these results to the extent of sports activity enjoyed by the accident victim. Assessment was made according to subjective, objective and functional criteria. The surgical group consisted of 52 patients and the conventionally treated group 31 patients. Subjective assessment of the surgical group showed 65.5% of the patients to have very good or good results, as opposed to 32% for the conventionally treated group. When related to average overall sports activities and when using the Innsbruck Scors a significant change was seen in both groups. Surgical patients who participated in competitive or leisure sports showed better results.

[Typical skiing injuries].

In a retrospective study of alpine skiing injuries which were seen at the Trauma Center of the University of Innsbruck in the years 1960-1991 a large change in "typical skiing injuries" was found. In the group of severe injuries, a large shift from the lower to the upper extremity (50.37%) has taken place. 3.93% of all patients were categorized as polytrauma patients in PTS groups II, IV, and 1.19% of all skiers died immediately after the injury. While 191 fractures and 118 capsular ligament injuries of the upper extremity were seen, 135 fractures and 229 severe capsular ligament lesions (mainly knee) of the lower extremity had to be treated.

[Treatment of acromioclavicular dislocations by a pin and tension band fixation].

Dislocations of the acromioclavicular joint are common injuries in sports and traffic accidents. The most widely used classification of these injuries is the one of Tossy, Tossy III and Tossy II injuries are indications for operative treatment. Among several different surgical approaches a very common procedure is the temporary fixation of the AC-joint by two pins, tendon band wiring and suturing of the ligaments. Recently we have been using a temporary transfixation by only one pin, tension band fixation with PDS and suturing of the ligaments. The advantages of this method are: preservation of clavicular rotation, easier operation and metal removal, and less damage of the joint cavity. Results and complications are presented.

Application of posterior plating and modifications in thoracolumbar spine injuries. Indication, techniques, and results.

Out of 281 patients with recent injuries to the thoracic and lumbar parts of the spine, 243 underwent posterior plating. Of these, 172 patients had an average follow-up of 3.2 years. The consecutive analysis of morphologic results led to modifications of the original Roy-Camille technique. In analogy to the system developed by Zielke for anterior derotation spondylodesis, plates were used in combination with VDS screws, threaded rods, and nuts, thus creating an implant with initial angle variability but final angle stability. The development of transpedicular reduction and cancellous bone grafting for the treatment of vertebral body fractures, later supplemented by transpedicular discectomy and intercorporal cancellous bone grafting, effected a significant improvement in the results of posterior plating. Although the use of traditional plating was followed by correction losses of 14 degrees, the loss could be reduced to less than 6 degrees by the new system, which nearly corresponds to the physiologic anatomy of the spine.

[The pattern of injuries of the ankle joint in ski boots--a retrospective analysis].

This study is dealing with the analysis of isolated ankle fractures in ski boots which are nowadays very seldom. Modern equipment and excellent prepared skiing facilities reduced this kind of trauma. In the early sixties about 60% of lower extremity injuries were caused by ankle fractures. Now, 25 years later, only 10% of injuries concerning to lower extremity are injuries of medial and lateral ankle or of the talofibular ligaments. At the department of trauma surgery of the university hospital of Innsbruck we use a questionnaire for winter sports injuries. We made a retrospective follow up study of the last three years, in which we found 100 patients with ankle injuries. Pilon tibial- and tibia shaft fractures are not included. The classification was made by the Lauge-Hansen system. Supination-inversion and supination-eversion fractures were found more often than others. Fractures of both medial and lateral ankles were only seen in three cases. One reason for this result could be a lack of movement of the ankle in the ski-boot. Modern plastic boots seem to protect ankle and distal tibia and fibula. Another remarkable result was the fact that we could not find any difference in the types of fractures comparing patients with released and not released bindings.

[What is the significance of posterior boot edge fracture in Alpine skiing?].

Lower leg fractures have decreased in number in alpine skiing since the winter season 1970/71. Yet it seems that the fracture rate remains at a 4% level since 1982/83. In this study we analysed 266 lower leg fractures treated in a period between october 1982 to october 1986 at the Department of Traumatology of the University of Innsbruck. When listing up the various types of lower leg fractures the numerous posterior boot top fractures were evident. These bending fractures with a dorsal wedge make up 82.1 percent of the open lower leg fractures. Radiological evaluation of the fracture type and the personal accident description give evidence of the fall mechanism. The dorsal bending fracture at the crossing of the middle to the distal third of the tibia is caused by a backward fall when the toepiece of today's ski-binding does not release the ski boot in the vertical plane. The high and stiff ski boot has no protective function in a backward fall and the so called "safety effect" of the calf muscles is not effective in such a case. This fracture occurs mainly in the 20 to 25 years age group. To avoid such serious lower leg fractures a toepiece of the ski-binding has to be found which releases not only in the transversal plane but also in the vertical plane, that is multidirectionally.

[25 years of Alpine skiing. In retrospect--the development and management of tibial fractures].

Due to the advancement in the development of ski, technique, equipment and improvement of the slopes in the last decades, there has been a change in the type, form and location of fractures of the lower leg. In a 25 year follow-up at the department of traumatology of the University of Innsbruck we analysed the winter months of the year 1960/61, 1970/71, 1980/81 and the year 1984/85. A shifting of the localization of injuries towards the upper part of the body has been found. There is no doubt that because of the development of modern ski-bindings lower-leg fractures have decreased significantly with adults. At the age between 11 and 15 years there has been no proportional change in the frequency of injuries. The operative treatment has increased in number in comparison with the conservatively treated fractures.

[Acute implantation technique of the ellipsoid heart for clinical left ventricular assistance (author's transl)].

The results of the first clinical trials of left ventricular assist devices are not encouraging. The only indication at present is in patients with cardiac failure after cardiac operations. The acute type of ellipsoid heart described in this paper-displays a canulation technique where the inflow canula inserted in the left ventricular cavity via the left atrium and the outflow canula is directly connected to the aortic canula of the cardiopulmonary bypass. The haemodynamic response shows the efficacy of this system. The circulation can be maintained in severe cardiac failure, as well as in ventricular fibrillation and cardiac arrest. On the basis of data obtained in experiments on 7 female calves this system is considered worthy of clinical trial.
