Objective: To compare functional and anatomical outcomes of closed reduction external fixation with Orthofix alone versus Orthofix supplemented by K-wires in distal radius comminuted intra-articular fractures.
Study Design: Quasi experimental study.
Place and Duration of Study: Department of Orthopedic Surgery, Sahiwal Teaching Hospital, Sahiwal, Pakistan from Jan 2025 to Apr 2025.
Methodology: Total 62 patients with closed distal radius comminuted intra-articular fractures (AO type 23-C3) were allocated into two groups with treating physician choice; Group-A external fixator plus K-wires, and Group-B external fixator alone. Functional outcome was assessed using Modified Mayo Wrist Score, while anatomical outcome was measured by radial length, radial angle, and volar tilt at 12 weeks postoperatively. Data were analyzed using SPSS 24. Independent sample t-test and Chi-square/Fisher’s exact test were applied, with p-value <0.05 considered significant.
Results: The mean MMWS at 12 weeks was significantly higher in Group-A (86.77±4.97) vs Group-B (83.54±7.34; p=0.047). At 6th-week postoperative assessment, volar tilt was significantly better in Group-A (11.80 ± 0.80°) versus Group-B (10.99 ± 0.86°; p<0.001), while no significant differences were observed in radial length (p=0.248) and radial angle (p=0.083). Functional outcomes were also more favorable in Group-A across most age groups, among females and in fall or sports-related injuries, though differences in RTA-related injuries were less marked.
Conclusion: The addition of K-wires to external fixation provides superior functional recovery and improved anatomical alignment particularly in terms of volar tilt, compared to external fixation alone in the management of distal radius comminuted intra-articular fractures.
