The history of electrical bone healing and the vast amount of laboratory and clinical data that support its efficacy are reviewed. The paper presents guidelines for the proper use of electrical stimulation and a description of the various systems available. The use of electrical stimulation to treat scaphoid fractures is covered in detail. Contraindications to the use of electrical stimulation are also addressed.
Low fractures of the femoral neck are often treated by reduction and internal fixation with a sliding screw and plate. In base of the neck fractures, a supplemental cannulated screw should be used to prevent rotation of the femoral head and neck during sliding screw insertion. It is critical that the large sliding screw and the smaller supplemental screw are inserted in parallel alignment, without impinging upon each other. This article describes an easily manufactured guide that facilitates parallel placement of the screws and assures adequate clearance between the two screws.
