RESUMEN
Introduction: Distal Radius Fracture Specially Colle's fracture is one of the most common fractures among the old patients it has many complications and causes a lot of problem for patients
Objective: One type of fracture is unstable fracture, which its treatment is more difficult, and there are different kinds of treatment for it. So we to decided study 543 patient with unstable distal radius fracture that had been treated with pin and plaster during 1997 - 2001
Material and Methods: We studied 543 patients with unstable fracture of the distal radius. In this method after reduction we insert two pins one distally into the base of second and third metacarpus and other proximally inside of the ulna or some time radius bone and after reduction We incorporate both sides of the pins into plaster for 6 to 8 weeks and finally we remove the cast and pins and follow up the patients in this study
Results: 189 cases were men and others were women .the ages of the patients were between 20 and 90 years. The complications were pin site infection 46 patients [8.4%], restriction of wrist movement in pronation and supination 43 patients [7.9%], flextion and extention 41 patient [7.5%], malunion in dorsal angulation of distal fragment 48 patients [8.8%], shortening of distal radius 44 patients [8.1%], nerve entraptment [carpal tunnel syndrome] 17 patients [3.1%], lateral displetment of distal radius 27 patients [4.9%]
Conclusion: The advantages of these methods are simplicity of application and cheapness for the patients and safety for the surgeon and patient with good result in compare of other methods the same as external fixation, open reduction internal fixation or percutaneous pin fixation under fluoroscopy
