Acetabular fracture presents a challenging situation to trauma surgeons today due to its complexity. Finite element (FE) models can be of great help as they can improve the surgical planning and post surgery patient management for those with acetabular fractures. We have developed a non-linear finite element model of the pelvis and validated its fracture(More)
Posterior wall fracture is one of the most common fracture types of the acetabulum and a conventional approach is to perform open reduction and internal fixation with a plate and screws. Percutaneous screw fixations, on the other hand, have recently gained attention due to their benefits such as less exposure and minimization of blood loss. However their(More)
In a controlled study, the cognitive functions measured by different association tests in a group of 40 schizophrenic inpatients (ICD 295.1+.3+.6) were compared to those of a control group that was matched according to age, sex and IQ. The results indicate that the basic cognitive functions of schizophrenic patients do not differ significantly from those of(More)

In a retrospective study 80 inpatients (Sociotherapy, Therapeutic Community) were compared to 160 outpatients (80 patient Day Clinic, 80 patients Night Clinic). With a mean treatment duration of 4-5 1/2 month a significant decrease was found for each group in the frequency and duration of further hospital admissions after end of therapy. Day and Night(More)
After describing horse-riding as a facility in managing mentally ill patients, a program for chronic schizophrenic in-patients is presented. Clinical experience with this program and also results of a controlled study are reported. The therapeutic value and slope for horse-riding are discussed in relation to different diagnoses.

The efficacy of a token economy system was assessed in a study involving 76 chronic schizophrenics who were inpatients during a treatment period of four years. The interrelations between therapeutic success on the one hand, and socio-economic as well as course of disease-related factors on the other were studied, including psychopathology and the efficacy(More)
