A Comparative Study of Fracture Fixation in Distal Radius: Cast Alone Versus Percutaneous K-Wire Fixation with Cast

Immobilization is traditionally used for conservative treatment, it often fails to maintain reduction in unstablefractures. Percutaneous K-wire fixation provides an alternative with potentially improved anatomical outcomes.Methods: A retrospective cohort study was conducted on 50 patients with closed distal radius fractures (AOtypes A2, A3, and C1), divided equally into two groups. Group A received closed reduction with casting alone,while Group B underwent closed reduction with percutaneous K-wire fixation followed by casting.Radiographic parameters—radial height, radial inclination, and ulnar variance—were measured immediatelypost-reduction and at 6-week follow-up. Functional evaluations included pain (VAS), range of motion, gripstrength, and patient satisfaction. Independent t-tests were used for statistical comparisons.Results: Group B showed significantly improved maintenance of anatomical alignment compared to Group A.Mean radial height was 9.4 ± 1.4 mm in Group B versus 7.0 ± 1.6 mm in Group A; radial inclination was 22.0 ±2.7° versus 17.8 ± 3.2°; and ulnar variance was +0.4 ± 0.5 mm versus +2.1 ± 0.8 mm, respectively (p < 0.001).Group B also demonstrated earlier return to activities, higher grip strength, lower pain scores, and greater patientsatisfaction.Conclusion: Percutaneous K-wire fixation with casting may offer improved radiological and functionaloutcomes compared to casting alone for unstable distal radius fractures. Further prospective studies arewarranted to confirm these findings.
