Anatomic reduction and stable internal fixation are effective methods for achieving optimal functional results in adult forearm fractures. High success rates of union were reported with absolute stability using conventional lowcontact dynamic compression plating, particularly in the treatment of simple forearm diaphyseal fractures. Locking plates are biomechanically stronger implants, allowing biological fracture fixation. As fixation with the locking plates does not result in a compression force on the bone beneath the implant, the incidence of bone necrosis due to interruption of the blood supply and periosteal damage is lower. However there is still need maximum compression for optimal healing in simple transverse or short oblique fractures, using lag screws or positioning the screws into the combined hole eccentrically. After the achievement of the compression at the fracture surface, locking screws are added to the fixation within the purpose of neutralization. Locking plates can be placed using bridge plating technique for the treatment of comminuted fractures. Recent studies have shown that locking plates have no superiority to conventional plates, particularly in the treatment of diaphyseal forearm fractures. However, compression in the fracture zone with more rigid fixation is possible with locking plates thanks to their combined holes. When applied in accordance with the basic principles of fixation, locking plating may offer similar results to those of conventional plating in the treatment of adult forearm fractures.
