[Fractures of the acetabulum (author's transl)].

The results of conservative and operative treatment of dislocated fractures of the acetabulum are compared. The types of fracture are described where surgical stabilisation is indicated. Depending of the type of fracture, the causes of unsatisfactory results following operative treatment are: primary lesions of the cartilage, difficulties with reduction and retention, septic complications. The aim of surgery is first of all the anatomic reconstruction of the supporting area of the acetabulum. 2/3 of our patients were operated between the 2nd and the 14th day. The lateral position with the extremity freely movable is recommended for dorsal and lateral approach. A trochanter traction screw with extension facilitates the operative reduction. It was possible to re-examine 45 of 64 cases after a period of between 2 and 13 years. Results were evaluated according to the scheme by Merle d'Aubigné. 35 patients had very good or good results, in 3 cases secondary arthrodesis was necessary and in one case a total hip prosthesis was implanted. Dislocated acetabular fractures should be be operated as soon as possible if conservative methods fail. Late reconstruction may also be successful. The lesion of the sciatic nerve is an absolute indication for operation. Satisfactory results can be achieved by anatomic reconstruction even in cases with multiple fragmentation.

[New classification of epiphyseal-plate injuries with regard to therapy and prognosis (author's transl)].

In this report a new simple classification of epiphyseal-plate injuries with regard to therapy and prognosis is pointed out. The classification can be used for each epiphysis and will be demonstrated on the injuries of the distal lower leg. Type I: There is complete separation of the epiphysis from the metaphysis without and with a metaphyseal fragment. The prognosis for growth is excellent after conservative or operative treatment. Type II: The fracture which is intraarticular (epiphyseal fragment) and the fracture across the full thickness of the epiphyseal plate and through a portion of the metaphysis needs accurate reduction. The prognosis for growth is good only after open operation. Type III: This relatively uncommon injury results from a very severe crushing force applied through the epiphysis to one area of the epiphyseal plate. The prognosis in this type is decidedly poor. The need for regular follow-up observation in these cases is obvious. At the end the good results of 40 patients after epiphyseal-plate injuries of the distal lower leg are presented.

Enflurane or halothane anaesthesia for patients with cerebral convulsive disorders?

Of a total of 45 patients suffering from epilepsy, 29 received enflurane and 11 halothane anaesthesia, while 5 were given both agents successively during the same operative procedure. EEGs recorded during anaesthesia were compared with the corresponding preoperative records taken while awake and during sleep. It was demonstrated that neither enflurane nor halothane exacerbates a pre-existing susceptibility to seizure activity and that both these inhalation anaesthetics are suitable for cases suffering from cerebral convulsive disorders.

[Childhood injuries treated at a university clinic for traumatology (author's transl)].

The accidents to all children up to the age of 14 years admitted to the I. Universitätsklinik für Unfallchirurgie in Wien in 1976 (2977 children) were analysed as to age-distribution, cause of accident, type and location of injury. There was an increase in accidents to older children. 13% of the injuries were due to traffic accidents; 60% occurred in the course of play; 27% on the field of sport. More than 60% were only minor injuries such as abrasions, lacerations, crushed fingers and toes etc., 30% bone fractures and ligamental injuries; 2,5% brain traumas. Most of the bone fractures were localized iment and no lethal injuries.

[Longitudinal rupture of the aortic arche (author's transl)].

This is a case report of a 75 year old man who sustained a longitudinal rupture of the aortic arch in addition to cerebral and extremity trauma following a traffic accident. An emergency operation without the use of the heart-lung-machine could not save the patient's life. Possible mechanisms leading to this unusual damage to the aortic arch are discussed.

[Enflurane anaesthesia for epileptic patients (author's transl)].

Enflurane anaesthesia with continuous EEG-registration was given to 21 patients, aged 3 to 53 years, who had a history of cerebral convulsions. 11 patients were children up to the age of 14 years. There was no obvious changes or correlation between enflurane concentration and intraoperative EEG-findings. The registered cramp potentials were the same as those registered preceeding the operations. Provocation as a result of the enflurane anaesthesia was not observed in any patient. The anticonvulsive basic treatment preceeding the operations made the interpretation of our results difficult. The warning by some authors against the use of Enflurane anaesthesia in patients with a history of cerebral convulsions could not be confirmed. Therefore, we conclude that a history of cerebral convulsions is not a general contraindication for the use of enflurane.
