Hướng dẫn giảm chấp nhận được là (1) xuyên tâm rút ngắn | Plating of the Distal Radius Arvind D. Nana MD Atul Joshi MD and David M. Lichtman MD Abstract Distal radius fractures are common injuries that can be treated by a variety of methods. Restoration of the distal radius anatomy within established guidelines yields the best short- and long-term results. Guidelines for acceptable reduction are 1 radial shortening 5 mm 2 radial inclination 15 3 sagittal tilt on lateral projection between 15 dorsal tilt and 20 volar tilt 4 intra-articular step-off 2 mm of the radiocarpal joint and 5 articular incongruity 2 mm of the sigmoid notch of the distal radius. Treatment options range from closed reduction and immobilization to open reduction with plates and screws options are differentiated based on their ability to reinforce and stabilize the three columns of the distal radius and ulna. Plating allows direct restoration of the anatomy stable internal fixation a decreased period of immobilization and early return of wrist function. Buttress plates reduce and stabilize vertical shear intra-articularfractures through an antiglide effect whereas conventional and locking plates address metaphyseal comminution and or preserve articular congruity reduction. With conventional and locking plates intraarticular fractures are directly reduced with buttress plates the plate itself helps reduce the intra-articular fracture. Complications associated with plating include tendon irritation or rupture and the need for plate removal. J Am Acad Orthop Surg 2005 13 159-171 Distal radius fractures constitute up to 15 of all extremity Patients include both active elderly individuals and younger persons involved in high-energy trauma. Consequently restoration of wrist function to close to preinjury levels is of concern to patients in both groups. Anatomic restoration of the distal radius and ulna is of major importance in achieving normal wrist function open reduction has become increasingly useful in reaching this goal. The advantages of .
