Functional outcome of cast immobilization versus volar-locked plate in fixation of AO type-C distal radial fractures in the elderly

Background Distal-end radius fractures account for 16% of all fractures. The incidence of this fracture has bimodal distribution with increasing number of elderly population affection. While closed reduction and cast immobilization may represent a good option in elderly patients, it may fail to maintain acceptable radiological parameters. Volar locking plate is an alternative option, but has its own complications. Patients and methods We prospectively conducted a study to compare the functional outcomes of isolated type-C distal radius fractures in 90 patients over 60 managed by closed reduction and cast immobilization (group A) or volar locking plates (group B). Patients were evaluated regarding radiological parameters, grip strength, range of motions, and quick disabiliy arm shoulder hand (DASH) score at 6 months follow-up. Results There was no statistical difference in range of motions between the two groups at 6 months follow-up. However, the results of quick DASH score and grip strength were better in group B with statistical significance at 3 months follow-up. No statistical differences in the results of quick DASH score and grip strength at 6 months follow-up. Conclusion Closed reduction and cast immobilization could provide an alternative comparable method for volar locking plates in the management of distal-end radius fractures in the geriatric population.
