The Treatment Method and Results of Percutaneous Pinning and Dynamic External Fixator Application for Unstable Distal Radius Fractures.

Objective The aim of the present study was to present the results of patients with unstable distal radius fracture treated with closed reduction and percutaneous fixation followed by application of the Pennig dynamic wrist fixator to allow early wrist motion. Methods Twenty-five patients diagnosed with distal radius fracture and treated with closed reduction and percutaneous fixation followed by application of a dynamic wrist fixator were included in the study. There were 15 (60%) male and 10 (40%) female patients. The mean age of the patients was 47.32 (20-76) years. The mean period between initial trauma and operation was 8.52 (1-23) days. All patients were allowed active shoulder, elbow, and finger exercises immediately after surgery. Results Radiological evaluation was performed according to the criteria described by Sarmiento and modified by Lidstrom. Results were excellent in 12 (46.15%), good in 11 (42.30%), and fair in 3 (11.55%) patients. No patient had poor result. Functional scores were assessed according to the Gartland-Werley classification and modified by Sarmiento. Results were excellent in 14 (56%), good in 8 (32%), and moderate in 3 (12%) patients. Conclusion Use of the Pennig dynamic wrist fixator in the treatment of unstable distal radius fractures has advantages, such as ease of use, minimal surgical trauma, allowing early rehabilitation, and early return to daily activities as well as increased anatomical and functional results.
