Functional Outcome of Displaced Intra-articular Fractures of the Distal Radius: Comparison of Closed Reduction Percutaneous Pinning with or without External Fixation versus Open Reduction Plate Fixation

Abstract

Objectives. The purpose of the study was to determine the outcomes of closed reduction percutaneous pinning (CRPP) with or without external fixation (EF) with open reduction and internal fixation (ORIF) using plate and screws. Methods. Outcomes of ORIF versus CRPP, with or without external fixation for intra-articular distal radius fractures were compared through a multicenter, non-randomized, ambispective cohort study. A validated Filipino version of the DASH score (FIL-DASH) was used as primary outcome measure.Results. The ORIF group consisted of 13 patients and the CRPP group, eight patients. Pain scores, post-operative complications and radiographic measurements were also evaluated. Mean FIL-DASH score for the ORIF group (M=26.69, SD=4.88) was significantly higher versus the CRPP group (M=14.59, SD=10.64; t(19)=3.58, p=0.002). No significant differences in radiologic parameters, pain scores, and complications were found.Conclusion. The study demonstrates that functional outcomes post-CRPP with or without external fixation compares favorably over ORIF for distal radius fractures at one-year post-surgery.
