Abstract
Introduction: Intraarticular fractures of distal radius are associated with high energy mechanisms, are severe and difficult to obtain a surgical reduction. The aim of our paper is to compare the clinical, radiographically and activity results in workers treated with surgical and conservative procedures.
MATERIAL AND METHODS: A prospective study was organized in 43 heavy-labour workers (34 male and 9 female) with unstable fractures of distal radius, treated between 2003 and 2005. The minimal follow-up was of one year. The mean age were 40 years (22–65 years) and dominant limb was involved in 40% of the cases. To treatment groups were established. Group 1, conservative treated with indirect reduction and cast immobilization (n=20) and Group 2 surgically treated with indirect reduction and percutaneous fixation with K-wires and cast immobilization (n=24).
Pain, mobility and radiograhs were evaluated and also strength (isokinetics), functionality (DASH score) and, finally, the return to work at 3, 6 and 12 months.
RESULTS: Fracture healing was obtained at 7 weeks but the time to return to work were 14 weeks after surgery. Pain score, at 12 months, were 2,3 points for conservative treatment and 2,9 points for the surgically group. The flexion – extension mobility loss, in relation to the contralateral wrist, was lesser in the conservative group at 3 and 6 month but similar (11°) at 12 months in both groups. Radiographs corrections were anatomically in 38% of the cases of group 1 and in 80% of group 2. Functional and strength results were similar in both groups. All the patients return to the same work activity.
CONCLUSIONS: Percutaneous fixation of unstable intraarticular distal radius fracture is comparable to the conservative treatment but the percentage of anatomical reductions was higher. It would be of importance in the evolution of the patients.
