Threaded Pin and Volar Plate Fixation of Distal Radius Fractures: Early Functional Recovery

To assess the results of threaded pin fixation and volar plate fixation of extra-articular distal radius fractures.

A retrospective case comparison study of patients undergoing operative fixation of distal radius fracture and postoperative therapy at 1 hand clinic was performed. Clinical variables included implant type along with the assessment of the volar tilt; radial height; postoperative wrist flexion, extension, pronation, and supination; key pinch; and grip strength. The duration of postoperative hand therapy was recorded. An independent Student t test was used to compare the 2 groups.

Forty-three patients were identified (21 threaded pin and 22 volar plate). The mean ages were 46 years and 54 years for the threaded pin and the volar plate groups, respectively. Preoperative and postoperative radiographic parameters were similar for both the groups. No loss of reduction was observed. There were no statistically significant differences for postoperative range of motion or pinch and grip strength at the time of discharge from therapy. The threaded pin group had a mean duration of 65 days of therapy, and the volar plate group had a mean duration of 132 days of therapy.

Both groups achieved equivalent range of motion and functional recovery; however, the threaded pin group required significantly less therapy than the volar plate group. At the time of discharge from therapy, radiographic and clinical outcomes were similar for both types of implants, but the patients treated with a threaded pin required significantly less therapy and were discharged from therapy an average of 67 days sooner than the patients undergoing volar plate fixation.
