Closed reduction and percutaneous Kirschner wire fixation of displaced Colles fracture in adults.
Pak J Surg Jan ;24(1):31-7.

Objective: To find out the outcome of percutaneous Kirschner wire fixation, after closed reduction, in Colles Fracture. Design & Duration: Quasi experimental prospective study from February 2005 to July 2007. Setting: Department of Orthopaedics (Unit I), Civil Hospital, Karachi. Patients: Thirty three adult patients with displaced Colles Fracture. Methodology: Closed reduction and manipulation was done followed by percutaneous Kirchner wire fixation of the displaced Colles fracture through radial styloid across the fracture and one pin was passed in the interval between first and second dorsal extensor compartment. After reduction and fixation the arm was immobilized in a cast above the elbow with the forearm and wrist in neutral position. Kirschner wire was removed after six weeks, followed by support with a wrist splint. The results were assessed by Weiland?s criteria based on radiology and statical analysis was done using t-test and p-value. Results: Out of the total 33 cases, the outcome was excellent in 7(21.2%), good in 25(75.8%), and fair in 1(3%) case. The overall success rate was more than 95%. There was a statistically significant difference from pre-operative to post-operative, on the average, in radial angle (t=10.82, p=0.001), palmar angle (t=19.74, p=0.001) and radial length (t=9.6, p=0.001). Conclusion: Percutaneous Kirschner wire fixation is a minimally invasive technique that provides an effective means of maintening the anatomical fracture reduction. It does not required highly skilled personnel or sophisticated tools for application.
