           Introduction: Distal radius fractures are common problem in upper extremity fractures that affect wrist function. Several treatments include closed reduction and casting, closed reduction and percutaneous Kirschner wire fixation, and open reduction with plate screw fixation. However, there are many factors to choose a treatment; the closed reduction and percutaneous Kirschner wire fixation are some of the choices that provide good results.

           Methodology: The study design was retrospective descriptive study. All distal radius fractured patients were undergoing closed reduction using Chinese finger trap and hoist assisted surgical technique and percutaneous Kirschner wire fixation surgery at Takuapa hospital between 1^st January 2018 and 31^st December 2019. Radiographic images were measured the angle and height of distal end radius, compared before and after surgery, number of wires, wire construct patterns and time to remove wires.

           Results: 64 patients underwent surgery. The mean preoperative radiographic measurements; tilt angle dorsal 15.6 degrees, radial inclination 15 degrees, radial height 6.5 mm., ulnar variance 1.35 mm. Compared with after surgery; tilt angle volar 2.1 degrees, radial inclination 22.7 degrees, radial height 10.8 mm., ulnar variance 0.44 mm. There were statistically significant difference (p< 0.001) all parameters. All patients used Kirschner wire 1.6 mm in diameter. 62.5% of patients used 3 Kirschner wires. 79.7% of patients used cross Kirschner construct fixation. The mean time to remove wire was 43.7 days.

           Conclusion: Distal radius fracture patients were undergoing closed reduction using Chinese finger trap and hoist assisted surgical technique, and percutaneous Kirschner wire fixation provided well acceptable radiological outcomes.
