Cambios radiográficos en fracturas de radio distal extraarticulares tratadas con fijación percutanea seis meses después del trauma

Abstract

Although not all malunions of distal radius fractures are symptomatic, the end point of the treatment of these fractures is to restore and maintain the anatomy of the radius until it heals, however with the use of closed reduction and percutaneous fixation it is not clear whether or not there are radiological changes over time. The anatomical reduction and the persistence of this reduction in the long term determines the likelihood of complications. The aim is to determine whether or not this treatment maintains radiographic stability measurements in patients with distal radius fractures with Clancey technique, evaluating pre-surgical, surgical and control six-month follow-up of patients treated at the Hospital Universitario Mayor, measuring the four radiological variables proposed by Graham in distal radius fractures (Radial inclination, radial height, volar tilt, ulnar variance) in 23 patients. In this way it can be determined which patients are indicated to perform this type of intervention. It was found that Clancey technique re-establishes the parameters of normality regarding the 4 radiological criteria but with the passage of time a loss of initial reduction is observed. No statistically significant differences were found in the different age groups. Although this technique is inexpensive compared to open reduction and internal fixation, the reduction that is achieved after the initial management is lost with the passage of time in a high percentage of patients.
