title: Internal fixation of fractures of the neck of the femur using von Bahr screws and allowing immediated weight bearing: a prospective clinical study.
abstract: This article presents the results of von Bahr screw fixation in 103 patients, allowing immediate weight bearing. After a follow-up period of 1 year, a failure rate of 18% was recorded. Analysis of the series shows that the failures are due to inadequate reduction of the displacement during operation, especially when the head is in varus, and to bad positions of the screw. The high failure rate was not related to the initial displacement of the fracture.
