This study is a blinded randomized control trial.50 patients between 18 and 70 age old with distal radius fracture are included.After dividing them randomly in two groups,during the first 6 hours of admission,the intervention group will be blocked by a anesthesiologist. In favor of making a continuous block lasting for 48 hours,a pomp will be attached to the end of the catheter. This pomp will infuse the anesthetic drug continuously.The control group will not undergo any block. Both groups will be visited on 24hr, 72 hr ,first week,mounths 1 ,2 and 6 for pain assessment and evaluating complex regional pain syndrome.CRPS will be diagnosed based on IASP criteria and data will be analyzed by SPSS18.
