[Special aspects of operative treatment for distal femoral condylar fractures].

The concept of AO condylarplate has enabled successful surgical stabilisation for severe condylar and supracondylar fractures in 58% of our patients. We analyzed 113 fractures between 1968 to 1987. Comminuted zones were fixed by special methods. In 42% we preferred reconstruction by AO condylar-buttress-plate and bridging technics. There were clear indications for cancellous bone grafts in 52.6%, for revascularisizing segmental fragments, for supporting medial cortical zones and defect areas. The analysis demonstrated the effectiveness of several operative variants in 80.8%. The results are likely to support current recommendations to the use of special stabilizing methods for difficult situations.

[Results of treatment of multifragment and comminuted fractures of the femoral shaft in adulthood. Results of a community study].

Progress in osteosynthesis techniques has enabled successful surgical stabilisation of femur fractures with multifragment and comminuted zones. Support plating, intramedullary nailing combined with cerclage wires, and interlocked nailing have proved to stand out as osteosynthesis methods for high stability. A retrospective study was conducted into 73 medical centres throughout the GDR to analyse the effectiveness of several variants of osteosynthesis in 939 adult patients who had received surgical treatment for femur fractures with severe traumatisation of the bone. Interlocked nailing proved to be unambiguously superior to other techniques for good results and low rates of complications. This analysis is likely to support current recommendations to the effect that interlocked nailing should be definitely preferred to cope with multifragment and comminuted femur fractures.

[Status of treatment and results in femur shaft fractures in the adult].

Surgical stabilisation by unambiguous principles of indication is the major purpose of the treatment of femur fractures in adults. An analysis of effectiveness is under discussion regarding various methods of osteosynthesis and their applicability to different types of cases. A comprehensive account is given in this study of methods chosen for and results of femur fracture treatment of more than 4,240 cases in 73 hospitals and wards throughout the GDR. Osteosynthesis accounts for 77 per cent of all approaches. This study, therefore, is confined to evaluation of surgical methods. The need for differentiated approaches is underlined by the results so far achieved. Particular emphasis is laid on the fact that in 85 per cent of all cases good results were obtained by intermedullary nailing.

[Plate osteosynthesis using the support principle].

In the operative treatment of fractures there are special principles for plating by support. Osteosynthesis is indicated for comminnuted fractures and bone defects in the metaphysis. Plating for distance also is established for fractures and pseudarthroses with defects in the diaphysis. This method is especially recommended for fractures of the head of the tibia and for reconstructing the pilon tibial.
