[Operative versus conservative treatment of non-displaced fractures of the scaphoid bone. Results of a controlled multicenter cohort study].

PURPOSE: Within a prospective, multicenter cohort study we investigated whether operative treatment of scaphoid bone fractures leads to earlier return to previous activity levels.

METHODS

Only isolated, acute, complete, stable and non-displaced fractures of the mid-third of the scaphoid bone were included. A total of 94 patients with the same number of fractures were recruited. In the operative group, fractures were fixed with a cannulated screw and had postoperative splint immobilization for a maximum of 1 week. In the conservative group a short arm cast was applied until fracture union was achieved. Both groups were followed for 6 months.

RESULTS

By 15 weeks patients receiving surgical treatment had returned significantly earlier to their full time work and home activities and achieved significantly better results for functional status, pain, and overall satisfaction. However, after screw fixation, complication rates concerning union and secondary operative management were higher.

CONCLUSION

Operative treatment primarily facilitates earlier return to previous activity levels, as well as better functional status, less pain and higher patient satisfaction, but conservative treatment seems to be safer and associated with a lower complication rate.
