[Follow-up results of osteosynthesis of medial femoral neck fractures with the dynamic hip screw].
The operative treatment of subcapital femoral neck fractures of stages Garden III and IV in the young patient is still a problem. The current methods of osteosynthesis show a high rate of avascular necrosis of the femoral head. We controlled 24 patients with subcapital femoral neck fracture, who were treated with a dynamic hip screw (DHS). The average age of these patients is 55 years. They were examined after 30-89 months from the operation. All patients were assessed regarding clinical and radiological parameters. All of the six patients with femoral neck fractures of stages Garden I and II had no pain, their clinical results were good. In one of these patients we found a partial avascular necrosis of the femoral head. Four out of the 18 patients with femoral neck fractures of stages Garden III and IV had painful complications, 3 of them needed a reoperation. Fourteen patients of the group with femoral neck fractures of stages Garden III and IV had no pain and wer satisfied with the result. But in this group we found 7 patients with partial avascular necrosis of the femoral head. These results are discussed and compared with data published elsewhere.
