A new method of operative stabilization of injuries of the dorsal ring of the pelvis is demonstrated. The necessity of conservation of the elasticity of the pelvic ring is discussed. ⋯ This method is simple and involves little risk. Special instruments and implants are not necessary.

Comparative Study
[Comparative results of compression and non-compression operation methods following medial femoral neck fracture].
This is a personal clinical and radiological follow-up of 65 patients with fractures of the femoral neck who were treated in 1973 to 1984 at our hospital. 30 patients were operated by nailing according to Smith-Petersen and in 35 patients osteosynthesis was performed by means of three or four lag screws. A comparative study between these two methods was done. The two main complications of femoral neck fracture, a vascular head necrosis and pseudarthrosis, were of special interest. ⋯ Fracture displacement was primarily responsible for the development of aseptic necrosis, but we could see also a relation between head necrosis and the inclination of the fracture line. Fractures of the type PIII/GIII/IV are those with the highest rate of avascular necrosis. Furthermore, the development of both, aseptic necrosis and pseudarthrosis, is strongly influenced by incomplete reduction.

Subject of this investigation is the influence of postoperative tibio-fibular ossification on the development of arthrosis of the ankle. Changes of the biomechanics of the joint can be evaluated by computed tomography. Posttraumatic and postoperative changes of the mobility of the fibular in relation to the tibia may be quantified by CT investigation and evaluated with respect to the development of arthrosis.

The medical expert as evidence in a liability process is himself under the criteria of accuracy which he has to proof by the doctor of his choice, for presentation at court. To know the viewpoints and circumstances are an assumption to judge the apparent lack of accuracy of the concerned person.
