A Comparison of Sugar Tong Splint and Radial Gutter Short Arm Splint after Closed Reduction of Distal Radius Fracture

Abstract

Purpose: Various methods of immobilization exist in the nonsurgical treatment of the distal radius fracture, among which sugar tong splint is the most commonly used. In this study, we observed the results after treating the distal radius fracture with radial gutter short arm splint without elbow immobilization.

Materials and Methods : Among the fracture of distal radius who have been under conservative treatment after closed reduction, 48 patients (from January to December of 2005) were treated with sugar tong splint, and 57 patients (from January to December of 2007) were treated with radial gutter short arm splint. The loss of reduction after closed reduction of the two groups was compared. The types of fractures were determined as either stable or unstable based on the fracture segment. Follow up examination of the stability was performed 8 weeks later.

Results: There were 105 patients (male, 52; female, 53) with mean age of 50.2. Of the 57 patients with the sugar tong splint, loss of reduction was shown in 11 cases out of the 31 unstable fractures and none in 17 stable fractures. In the radial gutter short arm splint group, 12 cases out of 33 unstable fractures showed loss of reduction. Only one case in 24 stable fractures treated by the radial gutter splint has failed. There was no statistically significant difference in the reduction loss rate between the two immobilizing methods (p-value=0.37), as well as the type of reduction loss (p-value>0.05).

Conclusion: Sugar tong splint and radial gutter short arm splint had no difference in maintaining reduction. Sugar tong splint has been considered as the most effective method of maintaining reduction by preventing rotation of the forearm and flexion-extension of the elbow. Furthermore, radial gutter short arm splint can minimize limitation of the elbow motion and daily life activity. Based on our results, radial gutter short arm splint, which only immobilize the wrist joint, had a good results as well.
