title: [Complications following osteosynthesis management of femoral neck fractures with spongiosa locking screws].
abstract: Osteosynthesis under pressure using two perforating cancellous bone screws in medial and lateral fractures of the neck of the femur and in some cases also in pertrochanteric fractures of the femur has proved successful, in our opinion, in surgery aimed at preserving the head of the femur, as has been confirmed at our hospital by follow-up studies. A striking fact that came to light during follow-up was that there was a higher percentage of incidence of necroses of the femoral head following Pauwels-I-type fractures. However, in our case it was only one necrosis of the head of the femur in a total of five Pauwels-I-type fractures treated by osteosynthesis. A final judgment can surely be passed only by studying a larger number of cases for a longer period of time. We will, therefore, follow up the fractures of the neck of the femur a few years later by re-examination. As a matter of principle, the aim of surgery in osteosynthesis of a medial femoral neck fracture can be attained by means of the cancellous bone screws. A very important aspect which is most essential for successful surgery is the accurate and controlled introduction of the screws via the guide wire. The infection risk is reduced by the small operative approach. In view of the fact that the follow-up examinations revealed more than 72% well-healed fractures of the neck of the femur, we do not think it necessary to effect any changes in our surgical procedure at the present time.
