Authors describe their new combined method for treatment of lower leg fractures. To this a new type fixator was developed which makes dynamization also possible. The other novelty in this country is the use of functional external fixing brace. In all of the 38 patients they had succeeded to obtain healing. No complication was found until now.
Authors report on the functional bracing of the fractured humerus. The advantage of the method is the preserved muscle and joint function with the use of a brace. This means ease for the patient in respect of the personal hygiene and living conditions. In elderly patients all other type of fixation around the chest means a substantial danger to the patients life because of the breath's movements depression.
Authors report on a new osteosynthesis based on the double nailing of femoral neck fracture and screwing, and developed from the "Uppsala" double screwing. The preliminaries of the double cannulated screwing method, its advantages, the experiences gained in 30 cases operated in one year and the early results are described.
The treatment of undisplaced femoral neck fractures, having been disputed for the past 50 years, is analysed on the basis of 111 observations during the period of 1981 to 1983. Osteosynthesis proved to be advantageous. Fixation with a three-flanged nail did not increase mortality rate, had no negative effect on late complications, while it could prevent dislocation and permitted full loading at an early stage.
An improvement of the results of treatment can be reached, beside respecting the indication of external fixateurs, with correct tactics of the treatment. Because of the disadvantages of the fixateur externe, we strive to restrict their use, to the time by all means necessary, and if possible to use other methods of fixation. This is motivated especially by the effect on fracture healing and the hindering of the movements and activity of the patient.
The value of internal fixation of fractures of the neck of the femur within 6 h was assessed in a review of a 3-year series. Three groups were compared, in which the operation was performed within 6 h, between 6 and 24 h and after 24 h respectively. The time and quality of union and the incidence of collapse of the head of the femur were significantly better in the first group. The difference in the results between the other two groups was not significant. In view of these data the authors recommend the internal fixation of fractures of the neck of the femur within 6 h.

A scanning electron microscopic study of the chondropathy of the patellar articular surfaces following knee injury was made. The early signs of degeneration were evident in the superficial membrane. Here, the fibres running parallel with the surface then turning deep become irregularly arranged, i.e. the amount of matrix embedding the fibres was reduced and the uncovered fibres became fragmented causing degeneration of the superficial membrane. During the progressive pathological process, as a result of the gradual deterioration of the interterritorial substance of the uncovered hyaline cartilage, spaces, fissures and deep pits were formed in the upper, then the lower, articular layers. The degeneration involved also the chondrons. With the disintegration of the chondrons the external and internal cell areolae disappear, the cell nests of chondrocytes are opened and the cells degenerate. Finally, the irregular cellular and fibrous structures and their remnants as well as the elements of connective tissue proliferation initially associated with the degenerative process can be visualized ultrastructurally.

The term 'deux étages fracture' is used in different meanings. Therefore, an exact definition seems necessary. 38 own cases of this kind treated in the last 5 years are analysed. Special problems of diagnosis and treatment of this type of fracture are dealt with. Because of the risky complications primary definitive treatment is emphasized especially in cases of compound fractures and in cases with severe simultaneous lesions.
A rather neglected method suitable for examination of the inner side of the knee-joint is discussed. After describing the types of arthroscope and the advantages and disadvantages of different techniques, the arthroscopic picture of the inner formations of the knee-joint is described. Results achieved during a year are summed up and the importance of arthroscopy in early diagnosis is emphasized.
